Would it be possible to set the delay time by electronic (switch-)
triggers instead of foot switches?
Well sure it would work to replace the foot switches, but the question
is does it work *continously*, for example syncing the delay to
the clock of an analogue sequencer or arpeggiator? (Or does the
tap tempo only work in a kind of "learn" mode?)
What, if the clock rate changes - will the Vortex' delay time follow?
Faster should be easier than longer, I guess. 

Does the Vortex do things like that?
Are there other Delay boxes that do such things?
