Sync for OP-1
Android app to back up and restore an original OP-1 over USB, with a tape and drum player
About
An Android app for the original OP-1. It creates and restores full backups over USB, plays the samples in your drum kits, and has a built-in four-track player for listening to your tapes. Version 0.0.6 was a rewrite that made backups much faster and the USB connection more stable, so you no longer have to reconnect between a backup and a restore. Builds are distributed as APKs from the author's GitHub releases.
