Matriach Arpeggiator Gate Length

So in the latest firmware update, CC control for Arpeggiator gate length was added. Which I’m a big fan of.

I was able to successfully adjust this via Ableton. However, it seems that once the synth is power cycled the synth returns to the default value (sounds like it’s around 50%).

I generally like a long gate length for the arp, more like the early 80s Rolands arps. Does anyone know if there is a way to either fix the gate length at a new value or access the parameter without an external midi device?

I guess best case would be if this was added as a Global parameter that could be adjusted.

Thanks in advance.

I’ve got the same question now, anyone have an answer please?
