Just wanted to share a fun little patch that shows how to use sah~ (sample-and-hold).
Try dragging around the pictslider. You can get some particularly interesting sounds in the lower-left corner.
A few weeks ago I got a noise/sample-and-hold module for my modular synth and with a little experimentation my friend and I coaxed some interesting growling sounds on it. I realized that sample-and-hold is a very basic but very misunderstood technique used in synthesis. Depending on how you use it, it can be:
A bitcrusher (run a signal through the left inlet, and a square wave at the resolution of your choice through the right inlet)
A random melody generator AKA "slow noise" (run a sampled-and-held signal into an oscillator, as shown in the "sah~-help" patch—very effective if you "quantize" the output of the sah~)
Similar to the previous, a step modulation generator (use it to modulate a filter or other effect)
A noise generator that sounds either like phase modulation or computer vocal sounds (my patch—run a simple signal like a sine wave through the left inlet and a square wave through the right inlet, and vary the pitch of both rhythmically).
What else do you use sah~ for?
