The TF will only send MIDICLK if the MIDI output is set to XMT. From your description, it sounds like your TF MIDI output is set to THRU. This is typical if you are using an external MIDI control. Is this correct?
If so, I would suggest a few solutions:
1. Use a MIDI merge box to merge the output of the TF and Musicom into the MF.
2. Just use the TF as a preset switcher, as all factor pedals are very capable MIDI transmitters.
3. If your Musicom has MIDICLK, use that, or get a MIDI controller that does have MIDICLIK.
