In either case first posting the Youtube commentary and then the commentary from Musical Android lastly the video and then will repost the video that he is mentioning.
It is a lot of insight for anyone that is curious about Soundcamp...
Video shot on my trusty Epic 4G (the original Galaxy S).
Screen recording done using screencast software baked into my custom ROM, MOAR 6.1:
Special thanks to tdunham for not only making a great ROM, but also trying to help me troubleshoot the pro audio early on.
Everything is tracked and edited in Soundcamp, Samsung's proprietary Digital Audio Workstation (DAW). I used the built in midi drum kit/MPC to perform the drum parts, and Heat Synthesizer to perform all the synth parts, then edited them in Soundcamp's surprisingly intuitive and capable MIDI editor.
I tracked guitar with a generic headset splitter adapter like this http://goo.gl/LYBRsR , and all vocals were recorded with the included headset microphone (you can also rig a regular dynamic mic with the right adapters) .
I used AmpliTube Free to add some grit, delay, and reverb to the guitar and lead vocals, then added some of Soundcamp's reverb presets to the backing vocals.
The overall process was surprisingly fun, and though not too difficult, there were a few issues.
There seems to be a glitch with cutting up audio. For some reason it creates a long gradual fade out effect. This meant virtually staying away from all forms of overdubs and audio editing. This is especially tough because there's no compression or volume envelopes to balance individual tracks.
When you reopen a saved project file the audio fx are bypassed, and Heat Synthesizer resets all of its settings as well so I have to tweak the sound every time I open it. Wouldn't be such a big deal, however, Soundcamp's really nice convenient SoundCloud export function exports the files from the saved project when they're offline, so anything that you have to go in and set or tweak will not be set right on export.
And, most likely because I'm running "supported" but older hardware, I think by the end I was running a little low on system resources to handle my project file (2-3 midi tracks and 4 audio tracks with several fx on them), especially when screen recording. They do have a "freeze" function to help cut down on processing needs, though.
Also, it seems like the pro audio functionality fights with Google Now somewhat, so I mostly leave Now disabled when using pro audio on the phone.
All and all, pretty impressed and happy with the functionality, especially as a tool to sketch ideas.
Commentary on the Musical Android post:
I made a video experimenting with Soundcamp and showing off some of the functionality as well, been waiting for low latency on Android since I got my Epic 4G (that didn't involve me dual booting linux anyway).
There was actually a major (and I do mean major) update between the time I tracked the midi and I tracked the audio, it gave the american version some of the things I noticed Marcus Padrini's video had but mine was lacking up until that point (the s harmonizer, s amp, etc..) and it dramatically improved midi playback for Heat Synthesizer on my phone (galaxy S5).
I touch on a few issues in the description as well, such as conflicts with Google Now and saving Heat Synth settings (though it could be because I'm using the free version), but it also can't handle advanced audio interfaces yet, like my RME Babyface (think that's the SDK, not just Soundcamp, I get a kernel panic when I unplug it in class compliant mode). However, I was able to get sound into it (and back out!) using the USB audio from my Zed10fx, which is just 2 in/2 out stereo channels, the mixer would just be less practical to carry around for remote recording or performing...but it is still pretty awesome.
