Simple one bar stereo looper sync’d to MIDI clock.

On Euroburo, hold bottom-left red control pushbutton for one bar until record mode engages. Red record bar will light up. For Zoia this button is duplicated on the main pads at the bottom-left corner of the pad.
Once the loop is recorded, press the green control pushbutton labeled ‘x fade’ to fade to the recording. Press it again to fade back to the live signal. This button is duplicated on the bottom row of the regular pad as well.

Fade to loop is instant, fade from loop to live signal is slewed.
