OT controlling Bass Station via MIDI

So I control my Novation Bass Station II via MIDI from the OT. I noticed that when I play an arpeggio from the OT and the BSII is doing its’ thing everything is fine until I start trying to send, say “recorded” filter modulation information from the OT. At that point the timing of the notes from the BSII goes to hell. BSII problem?
