What’s new

Version 1.4 · Updated October 24, 2026

Channel History: the app keeps each channel's last 20 versions, from before every upload, Perform load, save and restore. Put any of them back from Amp Settings → Backup. Compare two patches: select two in the Library and choose Compare… to see only the settings that differ. Setlist songs can have notes (capo, tuning, a lyric cue) and a tab link, both shown in Perform. Perform on the Lock Screen and in the Dynamic Island: the current song, its parts and the next song, with buttons to step through the set. The Help guide covers all of it, in five languages.
