About

A free browser tool that takes a tape backup from the OP-1 field (the tape.json plus the four track WAVs) and slices every track into its individual clips, silent gaps included. Clips are sorted into one folder per track and numbered in order, so you can drop a whole folder onto a DAW track and the clips line up the way they sat on the tape. Download clips one by one or as a zip.
