No. You should read the post by @sezare56 earlier in this topic that lists how the OT responds to receiving various MIDI notes on its audio tracks. Yous should also read Appendix C of the OT’s manual.
This may be due to a MIDI feedback loop. Do you still have a MIDI connection from the OT’s MIDI Out port to the DT’s MIDI In port? If so, try disconnecting it.
