[sdiy] polyphonic glide behavior

[Chris McDowell]

howdy list, 

what are your opinions on the "correct" polyphonic glide behavior? I have a simple polyphonic FM synth running on an stm32. I've been discussing with my brother about the "right" way to glide, none of which seem entirely right. 

The two cases explored so far, with 10 voices, voices assigned in round-robin fashion:

1: Glide from last note the voice played

this is the most "glidey" and the least behaved-sounding. 

2: glide from the closest previous note out of the voices

this sounds quite behaved, but whether the note will glide, or wont, feels random. a note is quite likely to not-glide, at least with my playing style. 


The next proposed case, which I have not implemented, would be to store the last chord played (all the notes played the last time > 0 keys were pressed) and glide from the closest note in that list. 


I'm nearing done thinking about this, hehe, but figured this list would be a great place to ask for opinions / experience. 

Cheers, 
Chris
