Hello,
I don’t have a Pam Pro to test this, but are you able to fully stop/start the clock output?
If Misha isn’t receiving any clock, then the sequence won’t proceed. So, if you can stop/start the clock from Pam, then that should be a way to trigger the Misha sequence on/off.
Or, you could send a gate out of Misha to the Pam “run” input. Then when you press play on Misha it should also run the Pam.
There’s probably a few ways to set this up depending on what you want to accomplish.
