MPE S&H — “MIDI Polyphonic Expression Sample And Hold” is a mouthful, isn’t it? — is a Max for Live MIDI Effect which allows gating and quantizing of MIDI notes and their MPE control data.
Sample-and-hold behavior can be triggered via multiple pathways, and you can dynamically bypass the effect on individual control types or the entire effect during playback. In addition to traditional “S&H” trigger behaviors which achieve step-like results, it also has windowing options for enabling “smearing”.
Use MPE S&H at any position in your MIDI Effect chain to overlay rhythmic texture on MPE or other MIDI.
Peruse the User Manual to see all that it’s capable of.
