So to implement this on the FM3/9 or fc6 I envision the switch hold function to enable the “morph“. Let’s say for this example that the morph would be a transition to 4db boost on the amp output level. How would you set this up?
Since you ask (I think your question was addressed to me?), here's an example of a simple solo boost:
Connect a CS to a footswitch. Visit the parameter(s) you want changed for the solo boost and attach a modifier with that CS source to it. Set the parameter range min and max values in the modifier that you want to jump from and to. Optionally add a little bit of damping if you want to make the transition less jarring. The switch will now jump back and forth between the two states.
This has an advantage over channels because you can change other parameters that are not related to the solo boost and they'll stay in sync in the two states. This also has the advantage that if you change channels or scenes, the solo boost will still work correctly. This method also works with midi switches, not just control switches. And of course it works for any two state transition, not just solo boost.
As for concerns about the cpu load, add a modifier to a parameter and see how much the cpu usage changes.
