A Looper (mono, in series) including Rec-Playback-Overdub instead of Rec-Overdub-Playback (left stomp switch: latching); plus Stop-Restart (right stomp switch); plus FadeOut (middle stomp switch long press) and Loop Reset (middle stomp switch release or short press)
Beware: if you reset the loop while in overdub mode, it will not do Rec-Playback-Overdub but Rec-Overdub-Playback next time you are recording.
Thanks Christopher H. M. Jacques for sharing the idea using a one shot sequencer!
The patch is named 5 2 9 because I am using it for a song called “Five to Nine” (second song in the video, 5:30).
