While experimental pieces are being posted…
I put this together a few nights ago. I used the lowpass and the 251 (sample and hold) much in this piece. Also used is my .com modular. Can’t remember exactly what came from where. 
The theme comes from a LFO going through sample and hold, having it’s speed change.. thus changing the outlying pattern at every turn… that CV was sent to osc #2 which was hard synced to what you hear, lowpassed, and then had the reso amount and frequency linked to the CV from the sample and hold .
