Clock and Reset out for Eurorack - not as easy as one might think...

[gwpt]

Hi Simon,
My primary use for Midronome will be to interface Ableton to eurorack.
So the CV outputs would ideally provide a clock and reset output.

This is not a trivial problem though, and there are many variants on the theme with regard to timing the reset pulse.
This article discusses some options:
https://learningmodular.com/master-clocks-reset/
This modules does "Reset output generating a reset trigger slightly preceeding the first clock signal":
https://www.shakmatmodular.com/products ... 0equipment.

These are things that need to be done to get the modules syncing properly, and is a pain in eurorack.
Happy to discuss, do any tests for you which can help work out the best way to do this.

Hi

Thanks for the info and the links! I'll definitely look more into this.

Just FYI for now the reset is not a pulse but a jump from 0 to 5V, similar a the start/stop pin on the sync24/DIN Sync protocol - https://en.wikipedia.org/wiki/DIN_sync

I'll do what I think is best before production, and then after many of you have a device we can look more into the specifics of how it works with each device. The device's firmware will be easily upgradable so it will be quick to make a firmware update to sort this out if needed

Cheers
Simon
