A4 program change to external - late when slaved

Having a bit of an issue with program changes with my slaved A4 driving a Moog Minitaur.
Setup is OTmk2 as master feeding A4. I want to use A4’s CV track (MIDI controlled via MIDI Out jack) to control my Minitaur but whenever I change a pattern on OT, A4 changes correctly and Minitaur doesn’t change patch until 1 pattern-length plays.
I’m aware of the issue with Elektron boxes needing to have same master scale/pattern length to stay synced (pattern-wise) but have no idea how to solve this one. I’m already using all 8 MIDI tracks on OT. I was considering adding another OT but it seems like this issue would remain if it plagues the A4 when slaved.
Any ideas?

The pc changes on the a4 aren’t designed for that purpose. I doubt you’ll find a work around.

Yeah, that’s what I figured but wanted confirmation.
A bit of a bummer.
