It´s Modular!

Always get excited when things are modular.

This is a new concept as it does not use a tradtional sequencer but reads the modules loaded with a sample/synthesizer in the order they are in the chain. 
So think that it can lead to happy accidents and to think a little bit more non-linear.
It is as is a little bit basic with not too much choice in modules but it looks like it can be expanded in all kinds of directions depending on the will of the creator.

It also records sound, making it a fun thing to use for enviromental sound collages.

It is for free and does not come with adverts.

Cool with a small new modular addition to the Android universe and if expanded futurewise can be something mighty interesting...

This music composition app lets you record sounds anytime and anywhere with your phone. You can arrange them in a graph-based scoring layout to create intriguing compositions.

Instead of starting with a cluttered interface narrowing your inspiration at the moment you open the app, the Pocket Composer starts with a blank white canvas, ready for your imagination.

Features:

- 16 track polyphony
- record sounds
- import .wav from SD-card
- synthesizer module
- audio fx: ringmodulator, delay, filters
- save and export to SD-card, share via e-mail, bluetooth, google drive, ...

This is made by a developer that have made some other apps that is based on using the Caustic engine. He is also the web director of the Cautic website, singlecellsoftware.com.

This app seems to me to be the most advanced one yet and if not paying attention it may seem simplistic but seeing the videos it shows to have a lot of possibilities that are not obvious and still being an easy app to use. (Having not used it though, it is still not clear to me how the synthesizer parts work).
​Can imagine that this would be a very good app for some people.
Also as it is based on the Caustic engine it will be very stable and probably work very good on lower spec devices. Always surprised how good Caustic works on my five year old devices that was not that good to begin with!

Drum Pad Beats is a fun beat/composer - scene/remixer to capture those ideas when that flash of inspiration hits while away from the studio.

Drum Pad Beats is aimed at users that want to create rhythms and melodies using pads and step sequencers. With the added ability to export their creations to wav, ogg or midi loops (zip, pcmsynth for Caustic), user ideas can be taken farther in mobile or desktop Digital Audio Workstations.

Great for sharing beats/tracks as dpb files and remixing another artist's track, the track could then be remixed again adding even more flavor. Drum Pad Beat's project file contains everything another user needs to take that idea even farther.

This app was pretty nice some years ago specially as there was not too many good apps competing but there was no saving so it was a little bit sad as personally did not feel much interest in spending time to have the work lost when closing the app...
Well I missed that there is now a Pro version that came out some months ago. with saving.
So it is nice for anyone that likes a nice beat box that is simple to work with and it does only cost two monies!
The free version is also still available to test...

Google Play:
https://play.google.com/store/apps/details?id=com.vtrsoftware.pureSynthPro

Vintage additive music synthesizer

pureSynth consists in four additive synthesizers plus one beat generator controlled by a five grid sequencers.

Synthesizers:

It's possible to save parameters of each synthetiser and load them individualy.

There is a view to control all parameters of all synthetisers and beatbox easily.

Each synthesizer has six oscillators to generate the fundamental note plus five harmonics: second, third, fifth, seventh and ninth. The oscillators can generating a sine wave, triangular wave, square wave and sawtooth wave. 

In order to control the notes pureSynth has an envelope controller which controls the attack time, decay time, sustain time, release time and sustain level.

It's posible to clear all marked notes pressing reset button(long click).

The note range accessible from the pad is controllable dragging a finger over it vertically. From midi note 12 to 84 is possible (7 octaves).

One LFO modulator is included in each synthesizer, it modulates the signal from 0 Hz to 20 Hz.

There are two sound effects possible: distortion and delay.

BeatBox:

Reproduces up to 12 sample beats and the volume of those beats can be controlled by separate. Those beats are: bell, block, clap, cymbal, hat, 3 difference kicks, misc, shaker and snare.

Sequencers:

There is a view to visualize all sequences of all sequencers where you can activate/deactive each sequence by separate.

Sequencers go up until 16 sequences of 16 steps. 


The main menu includes a three ways equalizer, BPM controller(from 25bpm to 200bpm), ON/OFF button and controls to record the audio output(all files are stored in pureSynth folder in sd card) which you can share with your contacts.

Have had fascination over the idea to create music from just vocals and have tried sometimes using Melodyne. For me it has not been easy as the things that come up using my head instead of an instrument or sequencer have been far less interesting.

In the end maybe having an instrument at hand to just pick out the notes is easier.
Having said that and maybe leaving the impression of negativity over such an app like this…
​I must say that I like it.

First on my mind was will it work, as there are other apps that have been trying their hands on note recognition but failed miserable. As anyone that tried these apps will tell you, that it is hard to use a garbled mess of random midi notes for anything.

Second was, will the app be used and not just occupying real estate on the phone/tablet?
Feel that yes there is definitively use for it. Maybe for me the first use is to quickly take out music that I am listening to without using an instrument and having the midi notes available for later.  Or use the bassline off a song as a starting point etc.

And yes it actually works! It does find the hummed notes with accuracy and there is some heavy algorithms going on behind the scene as it takes some times to transform the audio into midi, but it works.
There is also the problem of latency that they solved by letting the app listen to the metronome and audio recordings and get adjusted.
I mention these concerns as they are the most important to know if anyone is interested in getting the app.

​There is some setting up and trial and error but not too much and my biggest critique is that it only records two bars for each track but understandably it would be too heavy processing and waiting time otherwise. And for doing a bassline/melody/beat it works out fine.

Hopefully they maybe add a sequencer window that can be used for importing the midi and as such make longer tracks possible piece by piece.

Also feel that they should have a free version with maybe just one track and no saving or similar as even if it is not costing a fortune it is good to test it first just to know how well it performs on whatever device. But there is always possible to test it anyway and return it after an hour or two so it is not a big thing.

So it will be fun to see if I end up using this app or not but in either case I am happy that it is installed and having the possibilities that it offers.

P.s the sounds are General Midi but midi can be exported to use in other apps/programs.

HumBeatz is the revolutionary music making app that allows you 
to hum, whistle or beatbox and turn it into the musical instrument of 
your choice. Now you can quickly create musical parts and song sketches with just your voice!

HumBeatz is a four track loop recorder with two detection modes, Hum and Beatz. The detection mode translates your recordings to notes which are then played back by the included instruments or drum kits. You can also skip detection and use it as a simple loop recorder.

Hum detection allows you to quickly turn your whistling or humming into one of the over 30 virtual instrument included. Get your ideas out fast and easily anywhere!

Beatz detection translates your beatbox to any of the included drum 
kits! Using our machine learning algorithms you can also teach HumBeatz what types of sounds to use for your beatboxing.

Included with HumBeatz are a variety of drum kits and instruments, two effects (Reverb and Delay), a four-track Mix page and a Teach page.

HumBeatz is an excellent tool for any musician on the go and opens up music creation to everyone.

The developer has made one unique drum machine called Dragon and one Drone synthesizer called Wiisp. This is the latest app and is focused on using the motions sensors in a device for controlling a shitload of parameters.
Each parameter can be controlled by desired amount back n forth and sideways.

It really is worth spending some time with it to get out as much as possible from it.
Think this will appeal to people that are not afraid to take some time to find the sweet spots and some will be confused and run for shelter in more conventional music apps.

Yapps just like his other apps the graphics are bare bones which will scare off some but personally I find appealing, as it fits with the rawness that can be made sound wise.

Google Play:
play.google.com/store/apps/details?id=com.thiiird.fang

Fang is a synth app based on motion modulated control through accelerometer information. Each parameter can be linked to different directions of motion. Contains presets, WAV recording, a stepped arpeggiator with diatonic scale locking, a multi-pattern sequencer, wave shaping oscillators, resonant filter with envelope and pitch following, and an effects rig (including formant (vowel) filter, pitched delay, reverb, down-sample, bit reduction.) Capable of strange sonic textures, complex evolving arpeggios, or classic sequenced synth sounds.

Notes are generated with a sequencer and keyboard. The sequencer works by moving a step at the rate specified. There are four patterns that can be played and edited independently.

The keyboard has a set of notes that can be played or buttons which hold notes. Held notes can be cut off by sequencer notes and play notes of the same pitch.
The arpeggiator receives notes from the sequencer and keyboard. Its rate is controlled by both synced time and ms that are added together. It has variable steps, step transpose and gate. The steps and timing can be reset periodically with the optional arp reset. There is optional diatonic scale locking as well, allowing you to select a root note and scale from major, dorian, phyrygian, lydian, mixolydian, minor, and locrian.

The synth's sounds are generated with five voices, each with two oscillators that modulate between triangle and saw. Modulation is effected by an envelope. There is a pitch envelope that effects both oscillators. The oscillators are capable of fm (osc B modifying osc A.) Both oscillators can have their signals sent to the filter or directly to the amp envelope. A white noise signal can also be added to the filter or directly to the amp envelope.

The filter is a 4 pole resonant band-pass whose frequency can follow the pitch. It is also effected by its own ADSR envelope. The filtered and unfiltered signal is sent to a per voice down sample and per voice delay under synth menu. All voices are sent to an effect rig with a formant (vowel) filter, pitched delay, reverb, and bit reduction. Presets and WAV files are stored at /device root/fang/.

The new update of Noise Machine is not the biggest but an interesting one.

To pay for the premium version you do to get rid of the ever so annoying publicity that are a regular feature of many free apps but it also gives access to a sequencer.

If this would have been a more standard music app it would not have been too exciting, but Noise machine being focused on getting synthesized noise out of it. Being able to set different types of noisy oscillators, Lfo (different types) modulation, filter, delay and distorted ring modulation it can bring forth a whole lot of different flavors of noise.

This may not be obvious at first glance as the interface appears simple but rewards tweaking, with all kinds of goodness for musicians that are willing to step out of the comfort zone of commonly accepted norms.

Ahh so back to the sequencer… It is a simple sequencer but very useful as each of the sixteen steps can be programmed with one setting of noise. Making it possible to build rhythms of noise that would be hard to achieve without much more work in other ways.
There is also the added bonus of randomization of each step for the lazy ones. Giving way to unexpected surprises of course.

There is griones, always griones knocking at the door of perfection!

The most obvious one being that there is no way to save the sequenced pattern steps. So once the app is turned off… But it comes with internal recording for further chopping in an audio editor or for importing into other apps/programs.

Another thing that could be nice is to be able to see what Bpm the sequencer is set to.
So that is something that has to be set by ear or retro fitted later into wherever the recordings go later, if wanting to use it within music set to a specific beat.

Would love to see this concept taken farther with more tracks, effects etc as it is unique to be able to noise things up on an even deeper level!
Maybe the closest to (but not limited to noise generation) that is Grainstorm which I also recommend to check out. Grainstorm can also load sounds so it is a nice companion to Noise machine…

Have nothing against Mixvibes that released the application as they are making quality apps but...
Have never liked the loop based music making that is pervading electronic music making.
Buy some packs and sound like this, just put one loop together with some other loops in the style of... Ahh yes forgot the creative part... here we have put some fx to create originality...
Ohhh listen as the filter sweeps on a loop or two and as a delay trail down another sound and there it is, another song made that brings absolutely nothing to the table except an empty ego boost!

Maybe it is on my mind lately as my brother just started making music with such an app.
He is super excited showing me the music he is "making" and it sounds well produced but it brings absolutely no excitment or anything that resembles originality in any way form or shape.
The worst thing is that he is a pretty decent guitar player and knows some music theory etc. 

As popular music gets more and more mediocre for each passing year (this have been studied and proven analyzing popular music over the last fifty years) these types of apps just makes people create even more mediocracy to torture friends and family with!

Create any music in any style is the idea as he tortured me with his latest opus, explaining that he wanted to see if he could make a latin influenced track. Trying to be encouraging and awake all I can say is that the sound is good but maybe you could try to make your own melody and chord progressions. Knowing that he can do it but alás laziness and instant gratification is the name of the game. 

Something that is obvious is the contradiction that have arisen over the digital era of music making is that the more freedom and the easier it is to make music we definitvely is not gunning for new heights but have settled for excruciatingly bland music and each year more young ears thinks that it is normal and scoff at music that is alive and have some soul!

P.s
​Have nothing against music using a loop or two and there is a deep love and respect for Hip hop/rap (being a constant in my life) which is something different. 
The reaction to this way of music making is the pre-packaging and killing of creativity.
Also totally aware that it is not wrong that people enjoy themselves thinking that they are doing something creative and the ego feelgood that comes as a reward,
​but do believe that it is creating an environment for the future where that is more important than actually taking the human spirit to new levels of real beauty and broadening of our soul!

Seqvence is drum machine with step sequencer. You can create drum loops easily by creating drum patterns and combining them into longer sequences. It supports audio samples in wav, aiff and ogg format. 
You are able to store your work, and continue at any time. 
Furthermore, you can export and share your song with friends.

FEATURES

- Step sequencer with 6 channels and 1/32 note resolution

- Note velocity

- Pattern length of up to 4 bars

- 170 internal drum samples

- 20 internal drum kits

- Loads samples from SD card in wav, aiff and ogg format

- Fine tuning sample parameters (volume, panning, pitch, attack and decay)

- 16 bars Pattern sequencer

- 8 available patterns

- Export created loops to ogg or wav format

- Share exported audio

This developer have been around for a long time and the main idea of his earlier work has been the same as this latest one. Which is to make a multi track sequencer without much bells and whistles but fast to work with and still get good results.

I get the feeling too that it is meant to be for practicing which it would be good for. Just to lay some drums and bass for example and then play guitar to it etc.

One thing that is not seen in other apps on Android is the sequencer (it is possible to do the same things in most DAW's if one feels so inclined). There is no stepping in and out of different tracks, everything is on track and the instruments can be chosen from the sidebar.
So it is very simple to differentiate the different tracks and instruments as they are colour coded. This is great as you can see what any given track is up to while composing.
 
It is for free, no publicity and open source!

This is a little bit of old news but never saw it for one reason or another. It is an app for sequencing and composing with a whole lot of functions to help with all kinds theoretical issues. Have not explored it yet but it sure looks interesting. There is also a free PC version that can use VSTi's.
If you try it please leave your impressions in the comments section.

Helio is a cross-platform lightweight music speed-painting tool. It features linear-based sequencer with clean UI, integrated version control and more.

It is not so often lately that there is a new app and concept making an appearance. This looks like one. Have not tried it and am slightly skeptic as it seems more focused on the visual side of things but I could be wrong and it would have been good if they had a demo to try before as it is kind of expensive compared to other android apps.
But they do state that there will be a reduced free version soon.

Discovered this about a week ago and find it interesting as I am a guitar player and makes composing different than using a piano roll. It has a lot of things going for it which makes it look a little bit cluttered but personally I like that almost all functions are on one page and available.
It is also scalable so that makes everything even easier.
There is a free version for PC and a unpaid version that only have midi import/export disabled but you can still save songs.

Keywords: guitar, tabulature, tab, pro, music, sequencer, reason, tracker, rock, sampler

Have been playing with this some days now and it is a cool thing.
It is dirty and different. It is not sample based and comes with a handfull of effects.
The layout is to scroll from the top to the bottom, starting with the bass drum and ending with the effects section.
There is not many drum machines for Android based on synthesized drums so that makes this interesting but what makes it even more interesting is that there is no drum machine that sounds like it either.

​Anyone interested in aggressive noisy sounds or chiptune should definitevely check this out.
Do think that it is also good to have anyway as it fun to tweak and just being different makes it an added possibility that is hard to get to with other apps.
There is a demo that is useful if you want to sit and record into a DAW for example the full version comes with preset saving and soon to come audio recording.

It is made using Pure Data and ported to Android using LibGDX which is the same as the developer working on Pure Data Party apps. It seems to be shortest way for someone that wants to make quality apps but do not have years to spend how to code properly...

The developer is also active musically and you can hear his music here:

Dragon - Synth Drum Machine

Dragon is a drum machine built to quickly and easily make glitch, distorted, lofi drum beats and manipulate them live. The drums are simple and flexible, capable of some classic drum machine sounds and also new weirdness. Each is synthesized in real time and sent to a multi effect rig with variable speed stutter, bit reduction, pitched feedback delay and a resonant bandpass filter. The drums are triggered by a four pattern step sequencer. Patterns can be changed individually for each drum or triggered together for quick pattern switches for all drums.

Features:
Four pattern sequencer with local and global pattern control
BPM control with nudging
Save/load presets
Three drum synths:
-Bass
-Snare
-Hi-hat
Effects rig:
-Asymmetry and tanh(x) for tape like distortion
-Pitched feedback delay
-Retrigger (aka stutter/buffer) with variable speed and reversing
-Bit reduction
-Down-sample
-Reverb
-Resonant bandpass filter

Preset management requires permission for file storage read/write (optional on Android M+)

Unpaid version disables preset saving and audio recording

Audio recording coming soon. Possible future ports to desktop and ios. Made with Pure Data and libGDX

Full parameter and effect reference:

SYNTH PARAMETERS

Bass drum-
Freq: Frequency. Locks into semitones so you an harmonize easily
Decay: Amplitude decay
Freq Env Dec: Frequency envelope decay. Changes how fast the pitch drops
Freq Env Amt: Frequency envelope amount. Changes how much the pitch drops

Snare drum-
Tone Low Dec: Tone low decay
Tone High Dec: Tone high decay
Noise Dec: Noise decay
FM: Frequency modulate the low tone by the high tone
Freq: Frequency. Locks into semitones so you an harmonize easily, though overtones from fm and the high tone bring inharmonic tones
Freq Env: Frequency envelope. Changes how much the pitch drops
Delay: Feedback delay
Delay ms: Milliseconds of delay

Hi-Hat-
Freq: Frequency
FM: Frequency modulate the tone
Tone Dec: Tone decay
Tone Amp: Tone amplitude
Noise Dec: Noise decay
Noise Amp: Tone amplitude

EFFECTS

Retrig: Loop audio by the specified time interval (1/2, 1/8, 1/16, 1/32 notes)
Rev: reverse retrigger’s playback
Speed: control the speed of the retrigger’s playback

Bit Red: Bit reducer. Mixes in a low bit signal
BP Filt: Band-pass filter. All the way left is off
Tanh: Amplifies and the waveshapes the signal through a hyperbolic tangent curve. Creates a tape-like distortion
Asym: Adds to the signal, creating a DC offset. Doesn’t do much unless you have Tanh turned a bit
Down Samp: Down-sample the signal
Reverb: Mixes in reverb signal
Delay: Pitched feedback delay dry/wet
Delay ms: Milliseconds of delay
Freq: Adjust the pitch that the delayed signal is adjusted by. Also locks into semitones

The new features and a video demonstrating the Ableton Link feature.

Have not delved deeper into this but it looks like it could be one of the better composition tools on Android. It is using the General Midi instruments in your device but can export the midi for later use in other apps/software. Also interesting that they forego the pianoroll and use a more up to down tracker stylelee for composing. Made for easy re-harmonising and other handy tools for faster composing. Maybe a slight learning curve as it comes with more deeper functions than other midi sequencers but should be learnt in an hour or so without too much hassle.
Comes with in-app purchase...

Create your own music and songs and play with a multi-track MIDI sequencer.
Turn your ideas into full songs; write and modify sections, chords, notes, and drum hits, quickly and productively.
Immerse yourself in your music, make a song and play with more than one hundred instruments.
It combines several tools to let you quickly shape your songs while exploring different ideas.
For example you can try out different harmonies of a song section: write it once and hear how it sounds when played in different chord progressions, with the one-of-its kind feature of automatic harmonic transposition.
It includes a step sequencer for drum hits, a piano roll editor for detailed note editing, a rhythm editor to try out different rhythm alternatives. Plus, organize your song into sections and modify and repeat them at will. You will be amazed how fast, easy and fun writing music can be with this app.
The sounds are produced by the MIDI synthesizer of your device, so you can choose among all the 128 instruments specified by the General MIDI standard, which include many types of guitars, basses, pianos, brasses, strings, pads, synthesizers, percussion, woods and some effects.FEATURES
- Multi-track sequencer;
- 6 different editors;
- 128 instruments;
- Mixer to program each track's instrument and volume, and to mute/solo the tracks;
- Automatic Harmonic Transposition: lets you apply different chord progressions to the music you are writing, so as to choose whatever sounds best;
- Metronome;
- Playing range selection;
- Save and reuse groups of bars and chord progressions in other songs and/or tracks;
- Quickly copy and modify a section or an entire song;
- Automatic saving at each modification of your composition;
- Export to MIDI format: you can import the .mid file generated to your preferred DAW and take it to the next level, with further sound processing;
- Export all your songs, groups of bars, and chord progressions into the external memory of your device, so you can import all your library to another device, or make a backup copy of your work;
- Import from the external memory (what you have previously exported);
- In-depth integrated user manual, with everything explained.
MUSIC EDITORS
- Song Section Editor: to organize the sections (verses, choruses, etc.);
- Chords Editor: to write chord progressions;
- Tracks Editor: to organize the bars of the multi-track sequencer;
- Notes Editor: to write notes into the tracks;
- Drums Editor: step sequencer for percussive sounds;
- Rhythm Editor: to write chords based on rhythm;
WHAT THIS APP IS:
- Simply put: it's a tool to write and make music (your own music!) and we think it's quite good at it!
- It assists your music-writing creative process, from initial ideas to complete songs;
- You can use it for any type of music compositions, and it's particularly suited to songs;
- You can use it alone, or in combination with a DAW: first write a multi-track MIDI file, then import it in your DAW to apply audio effects and do more elaborate mixing;
- The benefits of using this app relative to another music editor is that it does things from the music composer point of view, rather than the sound/mixing engineer;
WHAT THIS APP IS NOT:
- It's not a tool to automatically generate music from loops or algorithms, you are regarded as a music composer, not just a user;
- It's not a one-fit-all tool: it excels in the creative, music-writing part of your work.
WHO CAN BENEFIT FROM THIS APP:
- Musicians, songwriters, composers, anyone who enjoys writing, composing and making music.
You don't need to be a professional musician to use this app, but it's better if you know at least the basics of music theory (but don't worry if you don't because this app can be an invaluable learning tool for you).
This free version is fully functional so you can make a full evaluation. Only saving and import/export are disabled.
Finally, it's an app written by musicians for musicians!

Wrote about Pure Data Party Publisher before but it is worth writing about again if missed.
So this is apps that can be connected together for jamming over wifi. 
There is a lot of more information on their website plus a lot of information on how to convert Pure Data patches into Android apps plus to make more apps to work in the Pure Data Party Publishers network. 
The apps are all for free and no publicity!
​
So go here and learn more:

In either case there is a new addition to the family called Manoury plus videos covering the different apps.

Google Play info regarding Manoury:

PPP-Manoury is meant to be used with other PPP instruments.
PPP-Manoury is a polyphonic 4 step sequencer ! 4 step is not much, but each step has a probability factor. The synth is a classic additive synth chained to a resonant filter and a 4 tape delay. With the right set of parameters you can go from 80s classics to deep generative textures.
PPP is a framework offering to support midi jamming over wifi features to audio applications and instruments. That means that apps can be connected to each other over wifi with a slave/master paradigm, enabling each sequencer to be in synch with each others. It can of course be used as a standalone sequencer. More here : http://ppp.mgsx.net

Pmfoundations has introduced Midi-Seq-8, a Eurorack Android to analog synth interface; and a companion Android app, MIDI Sequencer.
The Interface is sold as a full kit, consisting of a set of 2 high quality PCBs, front panel, all basic and precision components and a pre-programmed PIC processor.
The developer says that “The Midi-Seq-8 delivers the convenience of a smartphone or tablet-driven sequencer that directly controls your analog monophonic synthesizer from your Android device.”
Features:

• 8 MIDI channels supported which can drive 8 synth voices
• Play your own MIDI compositions on your synth from your phone
• Create and play CV sequences up to 16 steps on 8 channels
• Gate or Trigger mode
• Adjustable Clock in BPM
• Start / Stop /Rewind / Step
• 8HP wide

The module connects to your Android device using a micro USB cable. It uses a PIC 24 bit microprocessor to convert MIDI messages from the Android app into digital codes which are then converted into gate/trigger and control voltages for 8 channels with TI DACs. These are buffered with precision TI op amps, providing precise tracking over three octaves and to within 0.01V over 5 octaves.
The Interface is available via Pmfoundations for US $149, and the software is a free download via the Google Play store.
