Heya,
How's it going?
I am working on my guitar to MIDI converter,
and would now like to turn the polyphonic(max 6 voice) MIDI into monophonic MIDI.
I assume there is a neat way in Ruby, and I am hacking around with MIDI Split, MIDI Event and MIDI Mono.
Split and Mono both give just the last note played, which seems helpful, but how do I trigger just monophonically?
Mono gives number of voices playing.
Cheers and wishing your puzzles solved

Could you elaborate on this? Turning poly into mono midi would need some rules. What about chords? Which note should get through, what about overlapping notes, etc.?

It should be last note on,
and last note off.
No retrigging stolen.

Thanks for musing on this!

Does this work good enough for you? I might not have fully understood the task, but I think I'm close to it?

Perfect mate!
Thanks a bundle
I'll try and comprehend the code further,
although it is a little like mine with pushing and deleting.

I like that you don't just want a solution but actually understand the code, too. It isn't very complicated.

Each Note On event's key is stored in the buffer. As soon as the buffer has 2 entries, the oldest one (stored at index 0) is turned into a Note Off, deleted from the buffer and sent to the output. After that the NoteOn event of the new note is sent to the output as well.

Each Note Off event's key is deleted from the buffer. If the buffer is empty it means there is no older note and the current Note Off is sent to the output.
