Good day Rob. Issue is still happening. When they have been powered off for more than few minutes it keeps wanting to update firmware on startup. Only the ED4 but neither will work until update is done, then work fine until next power off.

Once I restarted again it did the same. I did the update then checked it and it wanted another update this time. So I did.

That seems to have corrected the issue.

Every time I power on the ED4 it will not work unless I update the firmware. Once the firmware is updated it has my current settings and works fine until I power it off and on again.
Connection details
ED4 - USB - ED10 - USB - PC

I can add that both 4 and 10 eDrumin work with Muzzio Drums.

Muzzio Drums are a three trigger dual zone cylinder setup. Base drum is single cylinder, single zone side mounted. Sizes are 8, 10, 12, 14, 16 toms, 14 snare and 20 base.

Thanks Rob. That has corrected it.

I just received my eDrumin 4. It is not recognized by the software when I plug direct to USB port. If I plug the 4 to the 10 the software recognizes it and it works but, it says no firmware found. I have re-installed the software and checked the cables. Here is a video to what I am seeing on the con...

Good day Rob. The pad has not been modified by me. I purchased it used but it was in mint condition. Maybe it is defective in some way. I no longer have the td-12 so can only test on ATV xD3. Not the best for testing this type of issue. I have a friend with a TD-50X. Will try it on that and see what...

Here is video link of me testing with bell and bow/edge cables connected. I tried to get the screen and me hitting the cymbal for reference. If you need screen only of the UI or anything else let me know.

I am triggering sounds on AD2 but, You can see the bell icon light up on the Edrumin panel when I hit it. I will try to grab some video later today. Thanks for looking.
