IIRC, meh. ;D Okay, it seems a little background info is in order. My plan is to create a guitar-like midi synth controller. I plan to use these pickups: http://www.stewmac.com/shop/Electronics,_pickups/Pickups:_Guitar,_electric/1/Graph_Tech_Ghost_Pickup_System_for_Guitar/Details.html#details to get separate signals for each string. I would then need to turn the volume of each signal into a midi-cc value which could be mapped to parameters in a synth engine. Now I could use vactrols or some other analog envelope follower method to create a usable voltage to put into an AIN module, but I was wondering if I could avoid that extra work by simply inputting the raw audio (scaled appropriately of course) to the AIN, and implementing envelope followers in the code. @ playbo$$- That VST looks awesome, but I don't necesarily want to use a computer with this midi controller. Thanks for the link, though. :)

thanks for the replies. :) A.C.: could you explain what iirc is? As far as AIN, I would need my audio signals to be between 0 and 5V. Is that right? tilted: I was trying to avoid any extra work (since I need to do 4-6 of these) but that might be the ticket.

Thanks for moving this... Didn't notice the design concepts section. Sorry.

Hey guys! I'm a noob here, so forgive the potentially dumb question.... I want to turn audio signals into midi-cc values. I plan to implement some kind of envelope follower to turn the audio signal into a usable control voltage, then into midi cc from there. My question is: can I just input the audio into the ain module, and then perform the envelope following digitally, using the pic in the core module? I was originally planning to use a hardware envelope follower design, but I thought that if I could use the core module to do this, I would save money and time and maintain more design flexibility. I need to do a minimum of 4 distinct audio stream>>envelope followers.
