I am not sure if any of the following provides the missing link, but here goes. (Maybe you have gotten past this.)
============================================
Multi Mode Channel Select: id = 129 (01,01)
min = 0; max = 31 
[I know the sysex manual says max = 15, but 16 -> 31 = C01B - C16B]
--Use this to specify which of the 32 channels subsequent Multi Mode Parmeter sysex commands will affect.

Example 1:
F0 18 0F 00 55 01 02 01 01 10 00 F7 
sets 01,01 to 10 00 [C01B]

F0 18 0F 00 55 01 02 04 01 40 00 F7 
sets 04, 01 [pan] to 40 00 [P00-center]
on the multi mode channel previously selected [C01B]
============================================
Preset Select: id = 897 (01,07)
(-1 = edit buffer)

Example 2:
F0 18 0F 00 55 01 02 01 07 7F 7F F7 
sets preset_select (01, 07) to the edit buffer (7f, 7f)

F0 18 0F 00 55 01 02 02 08 00 00 F7
sets preset_arp_mode (02, 08) to 00 00 [up]

F0 18 0F 00 55 01 02 02 08 07 00 F7  
sets preset_arp_mode (02, 08) to 07 00 [pattern]
============================================
The question then becomes what is the edit buffer? Is it the multi mode channel selected? Is it the basic channel that is selected?

As I said before, its been a while since I've done E-Mu sysex but based on my preliminary testing here, it looks like the multi mode channel selected and the edit buffer are two different things.

Anyhow, I am not sure this helps, but since I started re-exploring E-Mu sysex, I thought I write these results up.
