Advanced Gliding Help

#1

Hi!

I'm taking a note from a midi keyboard, then calculating a note higher than it and a note lower than it. This is fine, but THEN I want to be able to glide between the new high note and the new low note. With each new keypress I want to jump immediatly to the high pitch then glide to the low pitch (with the glide time controlled by another dial elsewhere - but looking at the glide objects I've found, this bit will be the easy bit).

The thing I'm struggling with is how to tell the glide object two notes at same time and that it should interpolate from high to the low, regardless of where it'd got to previously... can anyone help?

ok, I can only speak of the factory object , math/glide , as no idea what community objects do :slight_smile:

but you don't need to give two values to a glide, it glides from where it currently is, to the new value supplied , with the time given. (math/glide uses an exp curve for this)

usually use is just to put it in front of the oscillator pitch...

it doesn't care about high/low ,

if you want this logic, then you need to keep the previous value, and then compare it, use that into a mux to decide if you want to use the gliding value, or the value directly.
note: theres a little bit of 'additional complexity' , since you only want this check to happen on receipt of note_on, i.e gate transition, but I'll leave you to play with that :wink:

(its quite an interesting thing for you to 'solve', as it'll teach you something about 'conditional' logic in dsp, and the way that its not if/then/else like in normal programming, rather opening 'gates' to the required signal flow - which is why mux is such an important object)
