(At the risk of talking to myself) I’ve been thinking about this some more and it would be optimal to have a mix lock option for each algorithm within a program. This way, it’s up to the user to decide if algorithm A or B should be mix-locked while auditioning multiple presets and playing with routing options. The mix lock feature should then logically be in the ‘Presets’ edit mode. Holding down each Quick Knob for a couple seconds would enter mix lock mode to whatever mix values P, A, and B are currently set to. Ok, that’s my $.02. Thanks for considering!
