eDRUMin version 1.4 BETA now available

[Rob]

It's actually intermittent on both Windows and macOS. It's firmware issue related to a change that I had made to try to prevent MIDI Expression devices from being detected as eDRUMin devices when plugged into the host port. I'll revert the change and find a fix for the MIDI Expression devices sometime down the road.

• Fixed an issue in the last few builds that could prevent ED10 from properly detecting another eDRUMin in the USB Host port.

Alas, another random crash. This is Build 26, with the new 20ft cable. Report attached.

The crash indicates a stack overflow. You have to understand that the probability of data becoming corrupt increases with cable length. Even if just 1 bit flips from a 0 to a 1 or vice versa, that's enough to present the control application with invalid data that can cause a crash like this. I will try to add more safeguards to do deal with unexpected values in data packets, but I think the best solution is to follow the rules. Below is a webpage about maximum cable lengths and how to safely exceed them.

Thanks for the info. I just ordered a 16ft Active USB 2.0 extension cable. Will see how that works out and report back.

Crash report for 1.4.0.29. I was setting up a new note bank for a pad, and had just finished the head and SS notes. As soon as I left clicked RS the app crashed. When I reopened the app and went back to the rimshot note I was adjusting I think the note randomly changed to 19? Before it crashed I never got a chance to type anything in, and I don't believe it was at 19 to start. I set up a new note bank (#3) for one snare, and 5 tom pads. It only crashed that one time on the 3rd pad (out of 6).

So I was able to reproduce this crash three more times. The first time today (which I called crash 2, since it was basically the same from my original post) was unintentional and we again while I was doing a MIDI note edit. I thought I had picked up the steps to make it crash this time. I selected a MIDI note to edit, changed a note but didn't click off or enter or anything, then I triggered that zone. Crash occurred. When I opened the app again I made the MIDI note change and moved on. On the ride cymbal I was changing the bell MIDI note and I thought I would we see if I could make it crash again. Which I did. I selected the MIDI note for Bell, but changed nothing. I then triggered the bell zone several times no crash. I then changed the MIDI note, but didn't click off/enter/what have you, instead I immediately triggered the bell zone. The app crashed. So I was done at this point and I decided to get my task done and make the changes. On the last pad I was updating MIDI note for I tried it again, but I couldn't make it repeat.

However, just now I came back down to work on computer. I changed the snare drum (input 1) head MIDI note as before triggered the head and tried to make it crash. I even deleted the MIDI note and left it blank, but I still could not make it crash. Finally I hit Tom 1 head and the app crashed. I believe the snare drum MIDI note was still in a quasi editing state, or the action just before I hit Tom1 head was an edit of the MIDI note.

Confirmed. If editing a note and changing inputs, banks, or anything else that updates note note values with cause a crash on macOS. Fixed for the next build.

Changes in build 29

• Right-Clicking a note control will toggle notes/numbers for all note controls and setting is saved between sessions

First, this is major improvement and is very helpful. However, I don’t know what “saved between sessions” means. I changed from notes to number, and I went from every pad, pedal and note bank. Numbers remained the default everywhere, very nice. I assumed a session was closing the app and reopening. This did not work. Defaulted back to notes. However, I don’t think that is an issue for my own use case using a laptop.

The Windows version is working for me. When I start the app all the notes are numbers now.

Now the OS version of the app is remembering if MIDI note or number from the last session. Only thing I can tell that changed was some app crashes, but that could be just a coincidence.

Edit: I updated firmware to 1.4.0.30 and no change from my last session, which was MIDI numbers not notes. So I changed it back to notes, closed the app and reopened. The MIDI notes were number and not notes, therefore did not remember the last session. Next I changed the MIDI notes back to notes (not numbers) and triggered a crash via the issue Rob just identified. When I opened the app the MIDI notes were number again. So was not notes like the last session. This leads me to believe I had done or triggered something as I was editing some new note banks yesterday that happened to force the app to remember MIDI numbers not notes. Again not a major issue and I’m just happy with the change we already have.
