I think the whole moog/pedal thing came from Rush and their help in the development of the Taurus bass pedal...a lot of those classic/synth rock cats really buy into that pedal bs...lol. Haven't really heard any crazy pedal effect that wasn't available in some other form factor...pedals rarely make sense in a sampler setup.
However....I have a barker assmaster germanium for really distorting and overdriving the output of the voyager... They have a rack version, but the pedal sits on the desk and I can diddle knobs as needed. Pedals and synths go together quite nicely, seeing as how your right hand is usually noodling and your left is twiddling knobs...kick that shit on! Lol...hard to make adjustments when a pedal is on the floor though!
If you can afford/find one check out the Sherman filterbank....
