I'm not sure if this is useful, but I have an implementation of the Minimoog's key triggering in the [s_minimoog] object in https://github.com/danomatika/rc-patches https://github.com/danomatika/rc-patches

It basically keeps a sorted, unique list of the keys being held down & only allows the lowest note & velocity through. It also retriggers when the low key changes back and forth. It's fun to play with, like a real mono synth is :) As it's list-based, it may be too slow for your use case.

You not always want to mute the first note when a second note with the same pitch is triggered, regardless whether such an instrument exists or not. When creating software instruments, I often explicitly allow to trigger two or more notes of the same pitch because of the way it affects the sound. The phasing or (with a small amount of random pitch) pulsing can be nice.

of course, but since i try to find a nice solution for legato portamento playing monophonic synths in puredata (4 of them on different channels, see below), there is only really one voice sounding at a time.
