I have a Nerdseq with midi io. 

I connect my Digitakt directly to sequence the 6 cv trig channels. This works ok sometimes, but very often the gate will get stuck open. When I put the Nerdseq clock into midi Slave mode, the gates never switch off. So from the first note I cannot turn them off and end up having to power cycle to stop the gate. This is playing monophonically.

I can’t sequence via midi and have a synced clock at the same time. I have an Intellijel uMidi, which does not display this issue using the same setup. I really need to get this to work properly, it is particularly frustrating as I cannot sequence anything.

Can anyone help with this? Firmware is 1.16, the latest release.

Thanks,
Paul

Hey Paul,

i don't have the Digitakt to test your issues. However i recently got the Digitone and maybe i can reproduce it with that, too. But i got to learn first how to sequence midi with it, which might take a while as i am like 120% busy for the next 2 weeks.

However, lets clarify some things. First, it would be a shame to use the NerdSEQ only as a Midi-CV converter. (A quite expensive one as well )
Full power comes by it's own sequencing, something the digitakt can never archieve with midi.

Lets check your setup:
You sequence 6 independent channels with Midi-Notes, all independent and monophonic?
Are you sure you send Note-On and always Note-Off before a new Note-On with the digitakt (i don't know how deep the midi implementation is, so sorry if these are silly questions)?
Do you get also problems of you are only sequencing only 1 channel...2 channels...and so on?
Is it possible for you to record the midi stream with a tool like Midi-Ox or another Midi tool, so i could analyse the data?

The Intellijel uMidi has only 1 channel, so it's not possible to sequence 6 channels at the same time. There is a big difference as it only listens to 1 Midi channel. The NerdSEQ scans all Midi channels and routes them to the tracks and samples currently. ( The Midi implementation will get a major update in the future with flexible midi mapping functions) So i wouldn't consider that as a comparison.

So let me know so we can try to get to the problem and solve it if needed.

Cheers
Thomas

But it is actually different than i expected and it needs further research on the midi stream.
First of all i can sequence 4 channels Midi including Mod wheel changes with many notes without any issue. (more than 200 Bpm, already 20 minutes long including sequencing another track, + midi slave mode synchronised).

The problems begin at the point i press the stop button on the digitone. All notes that were playing stay ON. (thats most probably what you found out that tracks 2+4 were most affected...probably the most notes in your sequence)
Tracks which weren't playing a note are fine. Tracks which played a note are 'out of sync'. I assume when pressing stop, the channels which notes played didn't get a proper Note-Off command. And without a note-off command the NerdSEQ is counting the notes wrong (because for the NerdSEQ the note is still being pressed...counting is needed in case of polyphonic playing, so all notes can be released..and the sequencer clock doesn't matter here at all and is never an indicator for Midi-Notes).

So i expect that the digitone uses another trick/thing to do a note-off. I don't think it just don't send these when pressing stop (and stopping notes) as this is essential.
I will check the midi stream to see whats being send on a stop asap. (Or you do maybe, thats might be faster ;-))

Also, what i think to do as well is to add a 'Reset Midi Notes---often called the PANIC button ' function in the NerdSEQ so one can 'resynchronise' again in case of a hanging note.

btw: Now 42 minutes sequencing without a problem while writing this....I am sure it will be still in sync tomorrow without hanging notes if i would let it run ;-)

Thanks for looking into this. The main issue for me is that after gates have stuck open, and after I stop them using the Digitakt transport controls, any notes I play after that are immediately stuck on, regardless of receiving a midi note off signal. I might make a video to send you as it's hard to explain all this. But even playing the Digitone / Digitakt keyboard slowly I get stuck notes in seconds without touching any transport controls.
