Welcome

Kerf Modulators puts the modulation for a track in one place. Every plugin on the selected track gets a block of slots in a docked panel. Fill a slot with a modulator, map it, and it runs.

REAPER can modulate almost anything, but getting there usually means a parameter modulation dialog for each parameter, one window at a time. Kerf Modulators gathers it all into a single panel: envelopes you draw, LFOs, step sequences, followers, an XY pad and four macro knobs per track. Select another track and its blocks appear instead, while the first track carries on moving.

Everything is saved in the project, and every assigned modulator keeps running while the panel is closed.
