When changing presets that involves different "characters" there is a 50ms silence between them, so if you are working the full mix and in full wet, there will be an audible gap.
Because I'm sending my program changes quantized and taking into account that 50ms delay, I´m working my presets full dry then, 50 ms after the program change I send the real DryWet value. This makes the gap less audible
I wonder how you are dealing with this.
I don´t know if it is possible but it will be great that instead of a fade out to silence then fade in, to perform a fade to full dry then fade in to preset dry wet.
What do you think?
