I'm very tempted by this EHM pedal. With several factor pedals hooked together with midi it should be possible to control multiple pedals simultaneously as well. It might be interesting to combine pitch and filter effects for example. To be honest, I can't really find an equivalent pedal. Molten Voltage told me the Molten Midi pedals send midi data that isn't compatible with the Pitchfactor. The only other option is one of the large midi sequencers – which look very fun indeed and have many other functions to play with.
