Description
Based on the SLOOP web editor, it edits tracks, synth parameters, pattern notes with a piano roll and drum grid, DX7 SysEx patches, the user sample slots (loading files or recording from the phone, converted in the app) and the song order, with undo. It needs a phone with USB host support and an FM-1 already running a recent SLOOP. The release APK is signed with a debug key, so Android and Play Protect warn on install, and the app checks GitHub releases for updates.
Install notes
Download the APK on the phone and allow installs from that source; it can also be built from the repository. Back up the FM-1 first, since edits and sample writes can overwrite its data.
