Yup

Is there a path for vibrations to travel from your hihat cymbal to the cymbal?

For those Lemon users experiencing choke issues, does the choke get stuck in an on state such that every hit is choked, or is the problem that the occasional hit gets choked?

I don't actually own the TC-3, but rather made the circuit myself. Looking more closely at the schematic for that footswitch I see that the forward voltage drop of those diode is 1.1V, but the diode's I used during testing were the typical 0.7V. I'll order some new diodes and make the needed adjustm...

Increase the the xtalk control for you cymbal.

Thanks. I'll investigate.

For your 3 zone cymbal, put a 30k resistor in series with your bow piezo and I suspect it'll trigger the bell just fine.

I'm not sure why AD2 is not properly choking your open hihat, but that's unlikely an issue with your eDRUMin. The controls for splash sensitivity take into account other factors that can't be controlled from the UI, so maybe one of those is affecting your hats. That said, when I look at the movement...

No difference really except for the ED4 being a bit smaller than the ED8. If you don't need the MIDI in / out DIN, you might be better off just getting two ED8s.

Yes, eDRUMin 10 is available today. I will probably run out in a few weeks, but should have more units in about 2 months.
