Hi Garfield,
First off, thank you for the feedback. Much appreciated... and great point on the fact I did a 17 minute jam... it was me just mostly goofing around with the device and getting some sounds going.
One thing I really like to do with the Percal is to take the evelope out and control the filter with it. In this case I was driving part of the MS-22 via that for a while. It makes for some fun rythmic filter changes. (although I think i'll back off on some of the higher pitched sounds next time around... well maybe... :D )
To your question on what happens toward the end of the song:
The audio you are hearing at that point in the jam is actually the ALA Pique (https://www.modulargrid.net/e/after-later-audio-pique-upeaks) running the deadman's catch firmware in the split FM drum mode. That sound is the "snare" be manipulated.
it is kind of a fun little device and I thought i'd see how it does for making a kick and a snare-like sound for me.
Hope that helps!
As always, thank you for the feedback.
