Who can elaborate on this polyphony tutorial?

It’s regarding Polyphony, from Cycling74.

At that mark in the video, it introduces a better way to manage MIDI input with a float, edge~, and swap.

To my understanding the [mtof] sends a float to the right input of [float]. [float] holds it until [edge~] makes it output the value with a bang. [edge~] just receives 0 or non-0 signals. Then there’s a swap that deals with the [mtof] before sending out velocity.

Do I have that correct?

My other question is, what’s wrong doing it without [edge~], [float], and [swap]? I may have an idea but I’d like to hear someone’s opinion on how this improves performance?

i see no reason why you would use edge~ this way at all. you could just trigger the frequency value from the envelope input, or the other way round, start the envelope from the note input.
t b f, float, adsr~ … whatever.

in any case the timing accuracy of the generator will depend on the vector size. and if overdrive is on or not will not make a difference either in practice. (i assume that you normally have overdrive on, when playing audio in realtime.)

so, improving, yes.
