Well Christmas vacation is nearing an end, and I have my +/-12v power supply, all buttons/LEDs, the LCDs, and the 6 MIDI ports (via 4 IICs) functioning without a hitch!!! Wiring has been a troubleshooting nightmare and next time I’ll definitely want to try to make a PCB for all of the panel components – or at least mount everything on a single veroboard. Now I’m just rearranging things to make sure everything is mounted snugly & securely when the frontpanel is finally mounted in the enclosure.
Only thing left is the AOUTs. I’ve got 8x quarter inch jacks for CV Gates and 8x quarter inch jacks for CV Outs. I’ve got the gates going from the core, and I just wired in my AOUT module. Before I begin testing and adjusting those trimpots, I was wondering if anyone had tips for how to calibrate the AOUT gates & CVs without the MBCV application, assuming no access to analog modules? I’m guessing I just need to make sure I’ve got fresh batteries in my multi-meter and test the voltage… Should I be calibrating the CVs to make sure I’m getting exactly 1v/octave from 0v to 10v? Or is it -5v to 5v? What MIDI octaves are standardly used for which voltages? I have to admit my ignorance in this area. Should I try to use some sort of software oscilloscope as well? I’m mainly using these to control velocity/accent of analog drum modules, but also will be controlling VCO’s that need to be pitch-accurate. I could always save calibration for later, but this box is going to be a bitch to get back apart for that, and I’d like to avoid it if possible. Any tips on how you’ve done calibration before?
