It's fine to have positional sensing on those other pads, but they need to be using a different CC. And unfortunately there's no standardized way of doing it. Typically cc16 is reserved for snare and cc17 is reserved for ride, but for your toms, you would need to pick some other unused cc numbers an...

I'm guessing that some other pad has positional sensing on and is sending CC16. Check your other inputs and the SD3 MIDI log to confirm.

Not sure what the problem is, but it's not an eDRUMin issue. SD3 is showing note 26 coming through, so the eDRUMin is sending the correct note.

If you update to the latest version, you won't be able to downgrade without losing your settings. I can't promise the update process will preserve all your settings as there have been a lot of changes since version 1.6 and I just don't have the resources to test updating from very older firmware. Al...

I assume the problem goes away if you completely disable possitional sensing and restart SD3?

That's pretty old firmware and a lot has changed since then, including lots of bug fixes and improved functionality. Are you setup in a DAW environment?

I've posted build 31. For this build, I simulated a faulty cymbal / connector / cable where some of the piezo signal is being fed into the ring signal and made sure my edge and choke detection could still function properly in those conditions. Hopefully this finally resolves the auto choking problem...

I suspect that some of the piezo signal is getting mixed into the switch signal. Not sure. I think I need to rethink things. I don't want to create a technical support nightmare, even if the culprit is a cymbal that has mechanical issues.

What interface are you using that lets you go down to 8 sample buffers? I'm using an RME Babyface and it only lets me go down to 48 samples.
