I think the software generated envs on the jp6 were cheaper too. 14bit 
quantization you say hmmm that's a lot better than 7bits. 

Is it very hard to dig into those analog monster like the jp8? I guess 
everything is pretty much cramped together, so that should be quite 
difficult to change something or? I'm really wondering how much effort 
and time it will take to reroute the panel CVs to the CVins of the 
circuitry and still be able to switch between the adc and direct CV. 
Or at least change the adc to 16bits. All those digital parts are 
ridiculously cheap now, some 1mb sim into it maybe a different 
microcontroller/chip in it some programming and done, but it wouldn't 
be all analogue like the first option. 

I had in mind just to own an poly an. synth and a small to medium 
modular. Going digital is still to early, the industry should first 
get that damn parameter input on those VA synths better, 7bits is way 
too small.
