First of all excuse me there’s the possibility that this is a question just submitted… I try to find in the forum but without results.
I’m using two midiboxes connected together with the classic tx and rx ports in this way:
first midibox with standard Midibox64 , the midiout of it ( port TX 25 ) connected with the midi in port ( port RX 26 ) of second pic, it work on channel 1
Second midibox running the scan matrix application of TK ( fast version) in an old keyboard ( midi merge function enable in the code) ,work on channel 1.
I’m suffer this kind of problem:
Few times it doesn’t put out the Note_off message and the results is that note always stay ON and I need to re-push the key for do the Note_off.
I notice that it happens when I move some pots in the first midibox, or when I’m playin’ hard ( e.g. slides) so this is my question.
Is it possible that the problem is caused by a kind of “data overflow” from the input of the second pic?
What’s about the performance of the midi merge feature? Is there any kind of filter on it?
I don’t think Midibox link will help in my case because I think this isn’t a loop problem: what do you think about?
And what’s about the sharing of the same channel: is this a problem?
there shouldn’t be a performance problem, especially not with sm_fast or sm_slow, as these routines are executed much faster than a new MIDI event could arrive.
How does it work if the first core is removed from the chain (keyboard directly connected to MIDI In of second core which executes sm_fast)?
If you still notice failures, try a dummy application w/o any app code but Merger enabled.
If you still notice failures after such a change, it’s a hardware issue (hints to such issues later if required)
If I remove the first core , I don’t have the problem.
If I upload a dummy app on second core with merger enable all work good ( I upload the slow version of SM)
So I think maybe is a hardware issue, maybe with the matrix I’m using, I have to do some tests on it, surely I can open a new treat if is a hardware compatibility problem, but it is very strange as if remove the first core the apps seems to work good!

p.s. I have some question about SM_fast but I post in a separate treat.
