New Pumice Raft

This patch began with an exploration of my much-neglected Toppobrillo Triple Wave Folder, a module I picked up second hand last year.

As far as I can tell, it's a pretty obscure unit and - to be absolutely honest - I haven't spent the time understanding its particulars. But above everything else, it's got loads of parameter control and can do beautiful things to a signal - both discrete and aggressively.

There's a lot more going on with the overall patch here, but the key feature is the Wave Folder, where one triangle wave is fed directly into it with degrees of bias across the three folds. Another triangle wave (the CV melody) is split between the mixer and also as a second input for the Wave Folder, which creates some interesting modulations. A lot of CV control is coming from the delightful Ochd LFO, which is driving two CV parameters on the Wave Folder: the first bias, and the overall bias - which *I think* results in the wave distortion that occurs at about the 30 second mark.

I need to read the manual! Mabye this week's modular theory cram.
