Tetra, program changes

[Jamieally]

Hi guys,
Is it possible to send Program Changes to the Tetra in Combo or Program mode?
I'm using Logic?

Yes.

I'm confused as to how the Program Changes work with combo/Multi mode. Can anybody explane. With 128 combos I don't understand why it doesn't change combo number when I sending. For eg. I'm on combo 10 I send a PC for 21. It still stays on combo 10.
I think it works ok in program mode. Any advice or explanation, I would be very grateful.
