Awesome! The circuit's so small you could build two behind a single panel and have series wave burping.

It sounds like maybe you're a candidate to go get a bunch of Electronotes? Smile

Yeah, Musical Engineer's Handbook and Builder's Guide from Electronotes would maybe be more up your alley. http://el ...

Double check that you've cut all the traces you were supposed to on the strip board and that your jumpers aren't shorting to anything.

If this is part of a Midi to CV converter, wouldn't the cheapest/easiest solution be to implement the glide before digital to analog conversion?

Sorry to contribute to the off topic, but the light ACX midi to CV was one of my first digital projects I built. I think it's great. You don't need a trimmer as long as your +5V reference is stable ...

Hey ya'll, so for the last few weeks, I've been working on another PIC based synth project that I'm excited about and I thought I would share it with the board.

The hardware consists of a 16F685 ...

For PIC inputs, I usually put a 1k resistor between in the pin and the input, and have schottky diodes going to +5V and ground in parallel with the pin. In general, schottky's act faster than zeners.

You should try sending zero volts to the +3.3 side. It might be that a pin has a pull-up resistor, and the switch is grounding out this pin.

If you're unsure about this, and want to check before ...

To me, inputs on horizontal rows, outputs on vertical columns seems more intuitive.

If you're looking to even up the square on your matrix, you should build a clock divider/multiplier into your sys ...

I've finished three modules this week! Some of the PCB stuffing on these was done in 2012, so maybe that's cheating, but I'm still happy.

I'm not sure if anyone on here didn't see this on Muffs forum, but I now have boards for this. $20 gets a PCB and a pre programmed PIC.

Hey ya'll. I got this prototype up and working and wanted to share it with folks. I've made a youtube video that shows a simple patch and I explain how this module works.

That looks rad, Phobos. I like the blue transformer.

Ah yes, thanks for reminding me! I do always mention in the build documentation what my nomenclature is (it is the SHADED side that is negative on all of my PCBs...so it is whatever colour the silks ...

The sound quality from my camera is TERRIBLE, but this module only does control signals.

Hey Aladan, you've got the Divide switch figured out correctly, and I think I will go back and edit the documentation to make sure that it's clear for everyone else.
