I have Ketron, Technics, and Roland and find myself going back to my Boss FV 300-L Analog pedal for two reasons.
One, I want total volume control instead of choosing parts to control. The wide sweep does an excellent job.
Two, It doesn't care what source you are using.
Caveat
I know there are advantages to some people in using their respective digital pedals.
