I have been playing a lot of outdoor shows recently mixed in with the normal club shows and have been manually adjusting delay and reverb to fit both types of venues. I understand the global level for delay and reverb and linking them as global blocks but I still have a question. As an example, one of my normal "indoor" presets may have delay set a 15% mix and another preset I normally would have at 30% mix. I assume if I link them to the global control both would have to be at the same value. It would be really nice for the global control over reverb and delay to based on a percentage of the current saved value of each preset. This would allow, for example, a 10% increase in mix parameter of both reverb and delay in all presets with one turn of a knob allowing each preset to retain its individual nuances only increased by the value of the global controller changes. Is this scenario or something similar currently possible? Thanks for any help on this subject.
