i don't know if this is still needed, but to me it is, as i am wanting minimal modules (only mcu/dac/gnd isolation/usb/volt reg/icsp header and some analog pins broken out)
note: no extra ram! (aka, the bare minimal needed)
here's my personal reasons:
space is a luxury to me
i don't need he midi dins, jack conenctors, microsd, it takes just too much space when i can simply use header pins for the jack sockets and midi.
cost reduction per pcb? (fewer components needed, smaller pcb size)
my plan with a few of these modules would be:
use them as simple oscillators/adsr envelopes/filters/compressor.
while using a axoloti core as effect processor (with the help of the DRAM)
if i need to get this with axoloti core modules on their own, it will:
require more space
require more money(?)
not be used to it's potential (if i use a axoloti core as a polyvoice oscillator, i down't need all the features like DRAM, sd, ect)
