Klockwerk - A MIDI clock generator



A small addition to my MDMA project: a MIDI clock generator

The firmware consists of just a couple of lines of code, and definitely isn't something that has not been done before. I still thought it is worth sharing, as I measured the precision and accuracy of this clock with the firmware running on the low-cost version of the Teensy development platform (of course the code also runs on an Arduino/Genuino). Considering that, even at 300 bpm, there is a timeframe of about 8 µsec between two clock signals, we are very good with both precision and accuracy, being in a range of lower than 0.05 µsec.

Again, we have MIDI over USB functionality out of the box, without any soldering required. DIN connections are also supported, and can be added with a cheap, and easy to implement, small circuit.

The code can be download from my GitHub repository, and is installed using these detailed instructions...

Feel free to expand it :)
