Sorry I can’t find how to do it in the manual…
In step program mode when you press bass note pad and hold and release it gives you length.
Is it possible to modify this length with shift + encoder?
or with another method?
Switch ‘Gated’ mode in the track settings on. Then when you go to shift plus step in tr mode, press 2 on the numpad to see the list and you can edit the gate length.
Thank you
