MIDI Gate Stuck

[XORadmin]

Hi,

I put a note on the Digitone with infinite length, started the sequencer, then pressed stop. It automatically sends a stop signal when you press stop - even if the sequenced midi event has not finished:

22:43:27.405 From Digitakt in 1 Clock
22:43:27.426 From Digitakt in 1 Clock
22:43:27.427 From Digitakt in 1 Note On 1 C3 100            Infinite Trig Length
22:43:27.447 From Digitakt in 1 Clock
22:43:27.468 From Digitakt in 1 Clock
22:43:28.197 From Digitakt in 1 Clock
22:43:28.218 From Digitakt in 1 Clock
22:43:28.231 From Digitakt in 1 Note Off 1 C3 0                  Automatic note off sent when sequencer stopped
22:43:28.231 From Digitakt in 1 Stop
22:43:28.239 From Digitakt in 1 Clock
22:43:28.322 From Digitakt in 1 Clock

Hey, i did some deep analysing of the Midi stream and my conclusion is that the Digitone does actually miss Note-Off messages sometimes. I don't know if it is solved with the latest Digitone firmware, but in 1.02 it is definitely wrong (not always, but often).
I am sequencing 4 channels of Midi including different note-length and many modulation wheel variations.
Here are 2 prooves of that, sniffing the Midi-Stream + Midi thru to the NerdSEQ



One Midi off is missing and it is exactly the track that gets stuck, of course.
Later on the Note on the track gets a note on when i start the sequencer again which ends up in 2 notes on on one track.

And here again (here i filtered out the Modulation and Clock messages for a better overview):



I get also here exactly the stuck note on the part (Track 3) where the note off missed.

So my conclusion is that not always all note-off messages are being send from the Digitone (and Digitakt as i expect) on Sequencer stop. I couldn't reproduce it with a only running sequencer yet, so i expect that this works.

I assume there is no problem with my midi-setup as i get exact the results with and without the midi interface in between.


Another thing i see is that if you press stop twice on the DigiTone fastly, it sends the Midi CC message: All sounds off. I could use that to 'resynchronise' the NerdSEQ to the DigiTone. I made a new version which will help you with that. So when you get to the stuck notes, pressing Stop twice on the DigiTone/Takt will turn all notes off on the NerdSEQ regardless of the ON state. It gets you back to a working situation. This is just a small workaround for you, will go for sure into the next version. 

I will update the DigiTone and check if it is still buggy. But that will take some days as i already mentioned.

Attached a new version with the Midi CC 'All Sounds off' message included.
