I remember on old e-u forum was a discussion re: Common frustrations regarding delay of one pattern with PG ch w from OT to md and mm.

As u guys worked out for performance, best to use notes on OT channel going to note assigned md pattern, setting length to inf, but can also confirm slight audible delays during first pattern page of md.

My workaround was always using an OT audio channel for the kick (main element that needs to be exactly in time). This method is workable although not perfect.

A fun technique with this method is building say 5 short fill patterns on md, assigned to adjacent pg ch notes, then on OT last bar p-lock a note to middle or first ‘md fill pattern’, then also p-lock same note with ramp or random lfo assigned to pitch at 2 and it will cycle through fills.
