Here is three apps that are made by Former Space Marine Software that are kind of quirky and will be of interest for some people making noisy/experimental music or just to add some flavors.

Circular Sound:

Circular Sound is a mobile musical instrument that interactively transforms your audio files into noisy soundscapes using granular synthesis and waveshaping. Select the directory on your device from which to load audio files, then click Start. Your sounds are arranged in a circle. Use one finger to mix your sounds, and the other to control the waves of noise they generate. It's musical chaos on your mobile phone! This destructive music app is available free on Android devices in the Google Play store.

Radio Synthesizer

Radio Synthesizer is a performable musical instrument that allows you to interactively apply radio-like sounds to your audio files. Drag your finger around the screen to mix in static and radio modulation. You can make your file sound like its coming from a distant radio station, or like its coming from a demonic radio station. Have fun and make hallucinatory soundscapes with Radio Synthesizer. This innovative music app is available free on Android devices in the Google Play store.

So it is a amplifier/effects app for guitar and they have implemented their own USB driver for low latency. It is hard to tell which sound cards it will work with but the developers have used it extensively with a Behringer UCG102 that is very cheap, one guy on the KVR forum saw it on eBay for 8 euros with shipping and handling!
In either case you can always download it and test it first on the sound card that you have.

I get happy when people develop something weird and different as this group called 
Al1 & Ant1 has done. It is a duo doing music / concerts and workshops where they share their homebuilt sound generators and show people how to do them.
The applications being a Android version of some of their creations.
It may seem a little bit limited but think that it is more than useful for some things if you take your time and dig into it. 
It is four different types of sound Generators / effects.
Being for Melody, drums/beat/percussion, recordings to device for manipulation and one that comes with the explanation; 
The Old barrels for consumption based on ancient recipes and ingredients... 
Which I think is the same sound generator as this being explained like this -"Les vieux fûts" keyboard gratin dish for gear of variable speed producing a note by the vibration of a blade attached to a guitar locked in a cage attached to an old scale. 
Okay guess the language gets slightly poetic as the developers are french and words gets spiced in translation but it does feel refreshing to read such a choice of words instead of straight on description of functions!
It is for free and no publicity so give it a try.
Here is some videos showing what the Android version is emulating.

So for a long time was waiting for a granular sample manipulator and found this one like two months ago...but...
Would have liked to have done an review but as the direct recording did not work and the developer do not want to answer my emails feel that I can not do an review as I do not know if the developer is looking into the issue of failed recording or what is the future plans for the application... To his defense he does say to test with demo version first in the Playstore description so if you want to try it that is the way to go.
Yes you can load samples but strangely enough only Flac or Mp3's in stereo formats. So to use this and if you are like me and the direct recording does not work (Samsung Galaxy S3 Android 4.3) you are going to have a media converter  installed to convert your audio files into Flac or Mp3.
Well outside of my big disappointment of not being able to record directly it does a nice job of granulating your sound files. 
As this is not going to be a review will just post the Playstore information and if you like me have been looking for some granular fun on your device and not having any other option you might want to look into this one? Except the direct recording and to only be able to manipulate Flac and Mp3 files it does work very good.

Realtime Granular Synthesis for Android.
Grainstorm takes sound data as input, granulates it and pushes it back to audio out in realtime. 
Input either comes from recordings over the internal mic or from audio files which the user can choose from disk and are decoded afterwards. Currently only .mp3 and .flac stereo formats are supported, the samplerate of the input has to match the samplerate of the device (which is determined automatically and is 44.1kHz in most cases) or the result will be time-stretched or time-shrinked respectively and the input file must not exceed a length of 7 minutes. 
There is a cursor which can be moved over the waveform to determine the exact position from where input is taken. The waveform can be zoomed in until one sampleframe per pixel is displayed. Thus the cursor can be moved as exactly as one sample if required.
The two other cursors determine start and stop position of playback. In combination with playbackspeed and the other parameters evolving sound textures, morphing over a short or long period like hours can be created.
Interesting results - always depending on what you take as input - which could be used for electronic music production can be achieved if input comes from sampled voices or synthesized sounds samples.Output can be recorded by pressing the record button. On the second press the recording is automatically saved in .wav format in the user's music folder.

Grainstorm performs pretty well on recent devices with multi-core CPUs. The DSP-part which is highly optimized and most of the GUI-part are written in C - interaction between both is fast.

Before downloading the unlocker you should make sure that Grainstorm works satisfyingly on your device. It is not recommended for "slow" devices. If you encounter clipping turn out all background services. If you still encounter clipping, then Grainstorm might not be suitable for your device.

Yes so here is a christmas song and why do I post it?
Because the vocals are  made entirely with an in- app (for free) of the vocoder for Caustic 3!
So if you did not know in the edit window where you can record and edit sound files that is accessible directly from the vocoder you go to the tools section and there is an application on the (just on your Android device not on the iOS version or the PC version) that is in the bottom left corner called Vocality. If you press this you can use any of the installed TTS voices that you have installed on your device, normally at least the Google one is there but there is more that you can buy or pay for. Open it and write the words that you want spoken manipulate the pitch and the speed of the voice and import into vocoder and you can make it sing or say whatever you are too afraid to say out loud yourself...
So again the singing in the song posted is made entirely using Vocality.
Maybe it does not sound so good but it shows you some possibilities and myself never heard it used to sing a whole song before.

So this application have been out there for a long time and was always thinking that I wanted to make some experiments using it as an effects unit, well it did not happen until now because they first made an update that increased the usability a good deal and yesterday they announced a 50% Halloween sale that will last until Halloween night... So Guess this is a good time to finally take some time to write about Robovox.

As many of you know there is a whole lot of voice changers for Android and most of them are just simple gimmicks and not good for much. 
This one though has some functions that makes it actually useful both in performance and as a tool.
The main part of the screen is by a touch matrix  that can be fixed to chromatic scale, 
making it useful for musical purposes by playing the pitches.
One thing you can do that do only exists for one other application of this kind is that you can connect the output to speakers or or into headphones and use the microphone in your device and use sound and manipulate in real time. This comes with some latency so how useful it is in a live setting depends a lot of what you want to do. In either case it is a good way to test out your ideas. There is though a setting that gets the latency down more if you have Android 4.2 or over- My device is stuck on 4.1.2 so have not had the opportunity to try how much lower the latency goes... 
The other way is of course to record and playback what you recorded and during the playback manipulate the sound. Here is where the update gets noted as now you do not have to record first and then press playback but playback gets started as soon you touch the sound matrix and stops when you lift up your finger. This can be used to good advantage. In the sound sample made with guitar there is an example how this can be used.
Of course you also can use the recording as a virtual instrument. 
One more thing that came in the last update was the ability to record 60 seconds instead of 30 seconds as before. This makes it effectively useful as an vocoder as most verses or refrains in a song are rarely more than a minute long. You can also record directly from the device into a multi track for example but you would not be able to manipulate the sound afterwards. So for myself would prefer to record and then output the recording from the device and record that into something else.
It would be so good if Mikrosonic could implement that you could open up wav files that you already have as you can not do that now and if this was the case you could take recordings from a piece of music that you are working on and just affect the track and it would be perfect to have one affected and one without effects and work from there.
The only way to do this now would be to play the track you want into Robovox recording it into your device through the speakers and line it up with your other recording/s.
Mikrosonic says that they are thinking of implementing the direct import of wav files and hopefully they do as it would make the application much more useful.

Lastly theres the effects themselves there is 24 of them  and some of them not too useful or good but would say that there is about five or six of them that makes the application worth buying.
Think in the end that Mikrosonic should develop something in the line of Robovox but cutting out the cheese and make a good effects application for more serious work.
Do not get me wrong because you can do serious work as it is but it would be nice to have something similar that pushed it into more of a musicians/producers perspective.

So here is some Sound samples the first ones with repeating notes of three different instruments first the unaffected then the Robovoxed one, the last two ones is a Steel String guitar and lastly my voice with some different voice modules.

There is a lot of space to experiment one last thing I did right now was to record a riff of fingerstyle guitar and it sounded very interesting. But save that for another time as I have to pick up my daughter now.

What is great with the mobile devices is when someone is coming up with new ways to use them- 
And here is one of them.
Feel ashamed to tell you all that when the app got downloaded and I tried to use it, did not understand the fundamentals and tried to use the microphone in the device resulting in no sound except the sound you play, tried different devices to no avail- 
but what the fuck, it got good reviews- 
even wrote the developer... sure that he is still laughing ti hi... 
(especially as he explains what I did wrong really clearly in the app description! But me and reading...)
No answer, so back to the video for the app- 
seeing that he is holding the fingers like boxing in the sound, so that got tried but still no success!!!
Ahhh the idiocy at play-  
Blame it all on my parents.

Finally it dawned on me that what is needed is to hold the speaker from the device as close as possible to the mouth and the whole reason that he is boxing in the sound is to get as much resonance as possible into his mouth.
So when this got figured out realized that you could actually do this with any sound!
Guess the louder you can get it the better and some sounds work better than others- 
The advantage with using this application is that the developer have figured out some of the better frequencies and also made the buttons as big as possible (going in one scale or other- eight buttons) so you can play it easier as the speaker is normally (or always?) on the back of the device. 
It does need some practice but think what you see in the official video is impressive enough to warrant a free download and go do your own experiments...

Wait hold on! 

Two thoughts more-

One:
It would probably be possible to use a small container to place over the speaker with a small tube out- not a too long a tube as the speaker on a device is not so strong and too much sound would get wasted before reaching your mouth...
Two:
You could do a prerecording of a synth or similar, 
play it back in any player and in this way not having to concentrate on playing at the same time...
Well lets add a third:
If you saw the videos from yesterdays post- 
make one and use a synthesizer from your device...

Pocket Talkbox

There is a reason that these gets posted but you will have to wait 'til tomorrow na na na na.

Want to try it but waiting for a device that can use OTG USB cable as that is needed for this to work and also necessary for a lower latency of the app...
The same developer also made another app that goes without OTG USB cable but as it is called Delay effects because it has so much latency so the developer is saying that you can use it to harmonize with yourself!!! 
Ahh you have to love that you can take a disadvantage and turn it around like that.
Anyway if there is someone that have tried the usbEffects app and want to tell us about it or give us some sound samples please do...
You can send your observations and/or sound files to here: 
musicalandroid@yahoo.com or post in the comments.
I am curious to hear how good it is and also if it is as they say that the latency through the OTG-USB is low enough to be usable as guitar effect...
