Yash!
Yash! stands for "Yet Another Sample & Hold", and it is based on the amazing schematic/module design by René Schmitz.
This design is so simple, so easy to build, yet, so usable, that I have built a whole bunch of these in Euro and in Serge format;
super simple to build, even on a small piece of stripboard.
A classic sample & hold module needs a trigger and a source to sample; in this M4L version, the trigger is a clock,
synced to Live (with swing) and the sample input is a collection of different noise types, like flat, 1/f, 1/f2, f, f2, crackle, gaussian
and even an MM5837 noise chip emulation. Why? With sampling from different sources, you'll get different "taste" of MIDI note streams.
After sampling, you can lock the internal shift register into 8 or 16 steps loops, then, you can scale the output.
Internally, there are 2 "circuits", one for notes and one for velocity.
With the (MIDI mappable) "flush" button, you can open the sample input temporary; you can let "new source" to sample flow in.
Please note, just like any other sample & hold, Yash! doesn't have a "memory cell"; you have to record the MIDI output onto a channel,
otherwise your random melody is gone after re-loading the session.
Yash! is great for "jamming", recording random loops from synths or browsing through patches, presets.
