Vortex Sound Research

I’m having a total mare trying to automate the VT-4 with my Cirklon. I’ve changed the midi channel and have matched it on the cirklon. I’ve checked out the midi implementation list and have found that pitch is controlled by pitch bend, and yet when I add pitch bend events to a sequence, it’s not affected in the slightest. I’ve switched my midi cables which didn’t give me any difference. If anyone has had success in automating effects units with a sequencer then please help! TIA!
