A Logic Cookbook for Synthesis

Event at start and/or end of note

Attibution: mdoudoroff

An edge detector will emit a trigger at the rise and/or fall of a gate

If you patch the note gate from a keyboard or sequencer to a rise/fall detector, you can use the resulting trigger or gate to make something else happen (play a sample, strike a low-pass gate, fire off another envelope, etc.) upon note onset and/or releases.

Note: rise/fall detection is uncommon as a standalone, exposed utility feature.


Result: depending on whether you’re detecting rise, fall or both, a percussive element is added to the start and/or end of each note played
