Playing "Rhythm" Parts from SoundCanvas in Logic

Hi folks,

I'm still tinkering with my new SC-880 and I've got a good amount of the basics sorted out, I think.

I'm able to set program changes per channel in Logic's "Event Viewer," where I can program a certain "part" or "tone" in via the DAW to change instruments at a certain measure of the song. However, this only works for the basic "tone" set as far as I can tell - I even get the "program" menu in Logic to show me the different names of the different "base tones" on the SoundCanvas (0 - GrandPiano through 127 - SFX Gunshot).

However, I am not able to access the "rhythm" parts doing this as they appear to be a separate "thing" in their own sub-menu. I am confident this is due to my inexperience. I am aware that per the basic settings, rhythm sounds are assigned to Part 10, but I cannot access them even when setting the program/channel in Logic to 10.

The manual states:

to set the Par Mode using MIDI messages, you need to use system-exclusive messages. For example, if you wish to set the Part Mode of Part A11 to Rhythm 2, transmit the following message (p.188):

F0 41 10 42 12 40 1A 15 02 0F F7
10: Device ID (17)
40 1A 15: Address
(USE FOR RHYTHM PART of Part A11)
02: Data (Part Mode Rhythm 2)

Presumably this is what Logic is doing in the background when I change the instrument via the "Program" menu.

Again, I imagine that this is probably elementary with a slightly-better understanding of MIDI and/or this is buried in the manual somewhere, but I'm hoping someone can point me in the right direction.

Cheers!
