Basic time envelope question

Hi there,

Basic question but important one !

Which parameter of the enveloppe does the midi note length affect?

I noticed that if i put a very short sustain the note length seems more effective am i right?

Look at it veeery closely and think again:


Hint: sustain is not a time parameter.

Basic, yes. Available in almost any introductory guide to envelopes, yes!

Which parameter does the MIDI note length affect? All of them. Note length is defined as time between note-on and note-off events, for which gate time is a synonym. Note-on begins the attack phase of the envelope, progresses while the note is held through the decay phase, and settles at the sustain level until note-off. Upon which the release phase begins. If note-off is received before the sustain phase, whichever phase was reached jumps directly to release.

Some envelopes have 'sub-phases' within these categories or ways to loop or rules or whatever, but that is the general explanation, which is largely applicable to all envelopes. Constructively, I would recommend considerably more background reading rather than asking questions like this. Not that anyone is unwilling to help, but this is reinventing the wheel.
