Zam, I understand your hesitance in releasing pcb's without testing! Over at groupdiy most just to do it to and let the community help debug :) I think you approach is better :). I most interested in your pid controll :) I have PCB manufacturing contacts and can get small runs done if needed... In terms of fader panals I am pretty good in that regard. My capsule cnc machine engraves pretty well... So to get started I need, MB_NG, midibox MBHP module, 1 AINSER, 1 AOUT_NG, 8 Din and 8 Dout. and a PID motor control.(.I have the schematic from groupdiy) ?? I may not need all of this for initial testing and learning? I actually have a RFQ out with TKD local distributor to get pricing. Can you share the Alps fader you used initially? I am thinking it would be a good place to start testing but I cant seem to find one with all three tracks. Do you think that the HUI protocol will work? What are the drawbacks? I am mostly interested in fader automation not mute or other actions really. I don't mind using a mouse now and then. I am not sold on protools long term but for now its what I have. This is cool stuff!!
