Track I created while learning Bitwig in Brian Bollman's tutorials, found here: https://www.youtube.com/playlist?list=PLppiTGoCM2hK-iqNRJzdCdOaRHYWDncW8

This creation was made using only the next actions in random or other mode.  The only control I really had during the recording was volume automation.  However, I did cheat at the end and changed the last three notes to give a bit more resolution to the piece.  
The piano notes you hear being played are all just variations of one sample.  I made several copies of the one sample and just pitched, stretched and reversed it.  I organized the new samples in five separate tracks that would be set to jump around at different intervals.  My thinking here was that I would create a layer of arpeggiators that would create a cloud of random notes.  I like how it turned out.  The other samples heard include a chord with pitched variations, percussion, and vocals.
