"Buchla 200e 291e Patched as Slew Processor!

Well kind of :) Here is the concept to try:

250e cv split into: 261e VCO CV input, then (using a banana to tinijax converter box) into the 291e ALL input. Then patch the ALL output of the 291e into the FM audio INPUT of the same 261e VCO. Then as you raise the VCA of the 291e.. you can add a sort of slew to the 261e sequence.

I also patched a 210e between the 250e and 291e input... this was to serve as a buffer - which helped stabilize the blending of the 2x CV's back into the 261e.

Of course, more experimentation is required - especially to find the "sweet spot" for the 291e filter cutoff and bandwidth settings. Also - the slew effect is really not very extreme - BUT it works!

I expanded the patch, and used a synced 281e channel to have a sort of rhythmic patch programmed slew.

Thank you for checking out the 200e experiment! I hope this leads to more possible sound for you to discover and use :)
