Chase Bliss Thermae: control note division (left toggle)

I’ve assigned three buttons on the MC6 to control the left toggle position on a Chase Bliss Thermae:

  • Quarter note (CC#21, value 1)
  • Dotted eight note (CC#21, value 2)
  • Eighth note (CC#21, value 3)

Clicking the assigned MC6 buttons does not change the left toggle/note division on the Thermae. By chance, has anyone had any luck with this?

Here are is the setting I have for the eighth note:

I think I have an answer for my own question. It looks as though Thermae has to be set to listen to MIDI clock, and have a MIDI clock source to listen to. Once that’s in place, I’m able to MIDI control the left toggle/note division.
