Rack40 is a free, browser-based UI that brings VCV Rack’s visual programming language to ZOIA patch building. Build and edit on a larger screen, then run the finished patch on the pedal without a laptop.

R40 Bloom Seq is a four-voice, self-playing Welcome patch for Rack40. The patch opens muted. Start with your amplifier low and raise the master VCA gradually. Back up the destination slot before importing the supplied slot-numbered file.

Rack40 edits are not automatically saved to ZOIA (Rack40 works within ZOIA’s existing architectural limitations). To keep an edited patch without the computer connected, export it from Rack40, load it onto ZOIA and save it on the pedal.
