The lead sound is the trombone sample shortened and looped, bit rate redux, overdrive, delay thru reverb, resonance envelope sweep, Lfo on bit rate redux amount, and lots of p locks and tweaks throughout.

For this one I used overbridge sidechaining to play a Kontakt harp sample into a high resonant random filt Lfo, distortion drive, delay into reverb, I play live and tweak as I play. Love the delay overdrive. Space music piece.
I play around with an Lfo on the sample slot selection, looping sample, I use random stop button presses to make the looper buffer override sound on whatever sequence step I want to accentuate
