Modular synth
you patch by hand
Drag modules onto the board. Click an output jack, then an input jack, to patch a cable between them - click a cable to remove it. Your patch autosaves in this browser, and you can copy a link to share it with anyone.
click modules to select them, then name your macro
fm / cutoff mod jacks accept a patch cable from an oscillator's or lfo's out jack to modulate that parameter. Select a group of modules with "make macro" to bundle them into one reusable box.
