Thank you.
Right mouse on the parameter Controller Assign/Snapshots
However, on a 3rd party vendor (JS), he has the Snapshots set only on the parameters of two parallel amps.
The Snapshots are labelled Clean, Push 1, Push 2, OD 1, OD 2. Stepping through these Snapshots does nothing, None of these settings change between Clean through to OD 2.
I must be missing something.
