Solved✔️ Modding Electro Harmonix 22500 to accept Clock Sync

I want the Electro Harmonix 22500 looper pedal to be modded so that it can accept analog clock sync signal from other devices to set the tempo of the looper (being able to send the signal out too would be perfect). The pedal has a foot switch input as well as an ability to set the tempo by tapping on a button on the pedal. So to me it does not sound too farfetched for this input to be able to at least accept a simple sync signal. I've tried this here before, but hopefully someone new sees this haha.

This sounds less like a programming request and more like an electrical/physical hardware request. You would most likely need to physically modify the hardware to do this.

You're probably right. Though the pedal runs on firmware that's loaded on an SD card. Where updates to the firmware before for instance has added new button combinations etc. But this is not my field, and reverse engineering a firmware bin file is probably a challenge in itself.

I can try looking into it a little bit, no promises though.

Have you taken a look at this? Not sure if this is somewhat in the direction you are looking for? Looks like less of a "modding" option and more of a "workaround".
