Hi Paul,
are you referring to the I/O buffer settings in Logic? I changed those from 64 to 128 but the problem still exists. I didn't experience any latency issues on the slave (note delays etc.) to begin with. It all looks/sounds like as if the CPU is maxed out but the CPU meter on the VEP instance fluctuates only between 20% and 70%. The fewer tracks in an instance of VEP the less the dropouts/stuttering it seems. Could I have a wrong network setting between master and slave?
Thank you!
