Physical Modeling Module

I'm doing some research on a physical modeling module.
I try to tie this up to my old PM experiments
( http://www.jhaible.de/jh_ana_phys_mod.html ), making a dedicated module that contains all you need for a analogue physical modelling voice.

BBD, Waveshaper, VCA, Envelope Generator.

For accurate tracking, I try the following idea:

The board contains one of my "Living VCO" cores. The BBD, instead of having the usual HF VCO, is locked to that LVCO with a PLL and variable frequency divider.

I'm using low voltage BBDs (3207) because these are easier to come by in the long run, and their noisyness isn't a problem in a PM module, after all.

Unlike previous BBD projects, that's not a "safe" design where I expect "first time right" - I just make a PCB for myself now, to test the concept, and if I like it, I'll think of something more commercial.

interesting,but note that u realy need a proper (with the right responce/curves) adsr to synthesize acoustic intruments,so far our own tests combining seperate modules we only get best results with an ssm2050 adsr chip,other adsr's we tested (serge extended adsr,MOTM,3310,own design) just don't generate the 'right' shapes.

i did send u a PM

am gonna try to made and send u some demos asap with 3 different adsr's including the 2050
