RM SHAPERZ by noyzelab - ring mod / non-linear waveshaping progz for the tiptop z-dsp module

noyzelab has released RM SHAPERZ for free on GitLab.

Details:

"Ring mod / wave shaper style card for the TipTop Z-DSP synth module. Coded 2017 - 2019 in spincad with some minor assembler tweaks afterwards, mainly for level/offsetting. Each algorithm has 3 pots that are acting as vca controls for L & R input level [pots 0 &2], and pot 1 is output level for both left and right channels. The feedback controls are also very useful in these algorithms for further altering sound/waveshape.

Generally I have been driving this from a pair of vco outputs and is very good at adding harmonics in the [so called] east coast style. I got the idea for having vca on the inputs from the Serge ring mod, which has vc for the X & Y input levels, although not the output. I got that from my Hinton Music Lab, although that also has centre zero pots for levels/gain; anticlockwise is inverting input gain, and clockwise is non-inverting [something I have been thinking of maybe trying]. Of course the programs can be used for drums, vocals etc.. :]

if u find these progz useful please think about supporting my work either thru my bandcamp page: https://noyzelab.bandcamp.com/ or thru paypal or get in touch via noyzelab [at] gmail [dot] com

if u program up blank cards with a view to selling them to people, likewise please consider getting in touch, sending me something or contributing to my research / time costs in some way & givin me a shout :]

thanks, dave!
