please just more ganging options.
at the moment if you gang channels, it basically copies all the settings from the first channel into the next one (absolute)
with relative ganging you could, for instance, gang your gates for the toms without affecting the treshold or depth of each gate.
e.g.:
– when turning the treshold rotary on one tom, it will change the treshold of all the toms relatively to the previous setting
– for this one quiet part of the set you can just turn all the gates on the toms on/off while still keeping all the relative settings for each tom
