Blending lots of ideas from other places (unsurprising I'm sure). I first used FL Studio, and am more recently an owner of Ableton. Some things I like and dislike about both, so what I tried to do with my app is blend what I like.
E.g. FL Studio = step sequencer. Ableton = more intuitive (I think) for whole song composition. Of course, now Live 13 has a Step Sequencer...
The other areas I'm exploring is sound design. One goal in this effort is to remove dependencies on other tools as much as possible. So every sound you heard in my song is from the app alone - not some external sample or other synth/VST tool.
So, then suppose you sit down with a blank slate and draw a wave. Preview it. Now add bits and pieces on top. But more of a visual design canvas rather than the Reason-style rack wiring.
PS: Thank you for checking out the song!
