Mattson sample and hold used to sample pitch cv...

"Many of you no doubt already know this technique well, but I stumbled onto it today and thought I would share just in case. Usually sample and hold modules are used to sample an oscillator or audio signal... but here is what it sounds like if you use it to pluck a pitch here and there out of a melody.

When the tune starts, you see me dialing in and then adjusting the octave of a vco whose pitch is coming out of the sample and hold unit. The sample and hold is capturing pitch voltages at a very fast rate at first so it seems to play in unison with the other vco but I slow it down so you can hear it just grab a note here and there. You can also set this particlar mattson s&h module to track and hold so that on the downside of the clock cv it will just play the melody as is, and on the up-side it will hold whatever note it sampled....

the tune i have here probably doesn't do it much justice, but trust me, it sounds VERY and psychedelic with the right amount of reverse 'verb or multi-tap swelling. i was going to just use the effect (e.g., on my memory man hazarai) on the video, but then i realized it was too hard to hear what was going on... shrug!"
