Hi Soulshakers,
Another few options would be:
#2- If you have spare input channels, set up the scene with both kits and, if necessary, use a couple of mute groups to mute the channels not in use (so it’s super clear when mixing).
#3- Store channel libraries for the channels you have set up perfectly (I’m not sure if you mean the processing or mixes have been set up perfectly).
#4- Use channel safes to stop changes to any channels you want to keep the same when recalling scenes.
(Heirloom AVM’s advice would still be #1)
Cheers,
Keith.
