MIDI Expression devices are class compliant. They should work perfectly fine plugged directly into a USB port on Apple silicon Macs. The fact that there are no topics on the matter is good evidence that it should work. Maybe check your USB cable.

Yes, it's possible and is covered in the manual. It would be much easier to do with a MIDI Expression connected to the host port of an ED8 or ED10. You'll need to find a way to route the MIDI from the iO to the ED4. If you are using a DAW, then it should be simple enough.

Great. Thanks for the feedback.

Having a minimum value of 0 for velocity would be better since some keyboard don’t transmit Note On message at very light touch. I’m aware that a Note On message with a velocity of 0 is interpreted as Note Off but that should not be a problem. Having a 0-127 value range when transforming Value 2 wo...

Thanks for this information--I hadn't noticed your post until today--really happy to hear the auto-choking issue is resolved.

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.
