Output note off when none is received

#1

Hello all!

So I have been working for some time on a midi multi effect with the Axoloti. It all started off a bit as a way to learn the logic of the patcher by trying tio replicate the midi delay implemented in the Yamaha TX81Z. SInce then i added lots of another features, like random CC and PC sends as well as basic but useful stuff like an octave changer.

The patch I am working on is mainly designed so I can use basic notes sent by my LXR drum machine and transform them for improvisation live act.

It's getting there but I a bit stuck with a feature of the LXR that has been pretty annoying since quite some time:
The sequencer does not send note off data.
The only way to have a note stop is to add another note with 0 velocity on the sequencer just after the said note.

So now, because of this behavior, my midi delay does not work at all since I am sending notes to a monophonic synth (Shruthi). The first note sent stays on as long as the sequencer plays and only resets after it stops.

Would there be a way, with Axoloti, to add a note off right after each note received?

Not sure if I should focus on the in/keyb or or on the out/note…
There is a releaseVelocity in the midi/in/keyb but none on the midi/out/note…

thanks!

Ok erm, this is embarassing, I may have found the answer myself. It's maybe not the best way to do it but for the sake of sharing it if would be of any use:

I added a flipflop set by the gate of the midi/in/keyb and reset by a timer/delayedpulse. I can then feed the signal to the note/out.

Its very specific of what I wanted to achieve because this way, every incoming note will output the Axoloti withy the same length. I might add a external pot to control the length of the note later.

I guess the best way to do that would be to modify the code of the LXR, but that is way beyond my reach.

Pretty happy that the Axoloti is there also to compensate or add some feature to other devices.

This seems like a good solution, and no cause for embarrassment.

It is just that I have been looking at the wrong place, mainly trying to understand the midi code and modify it where there was an easier solution.
