Moog Grandmother seq/arp problem


#1

Has anyone had this problem/ know of a fix?
With midi in connected on the grandmother from the pyramid, the GM’s arp and sequencer dont function properly . Specifically the arp hold button only holds the last note played instead of all the nones, and recorded sequences play back all messed up?
I haven’t gone through the pyramids setting in a while , but I have 12 other synths and a couple drum machines connected that have been working fine for a long time. All my midi is routed through mergers and thru boxes .
Any help would be appreciated.
Thank you
