I'm producing audio using own samples in PreSonus Studio One[DAW], Audacity[Sample Record and editing], AVS Audio Editor[Similar usage as Audacity].
Currently the keyboard i have is only simple Samson Graphite M32. My main point on this way is to make ambient music and game soundtracks in future.
Currently i do not accept jobs for audio/music production but it will change soon. When i will have better hardware and some simple instruments i will back to it with huge kick! Whatever you can still hear some of my tests at soundcloud.com/megaerty
