OSC Newbie needs help

hello.

I am attempting to connect gig performer to my motu 828es
the 828es has its own internal mixer and it does some good stuff but I want to use gig performer for some extra processing.
I would love to be able to control the Gain, Pad, 48V, and Phase direct from gig performer on a widget.
Motu Has OSC UDP enabled to allow me to change settings on the mixer and has some what I guess are some defined OSC “commands” or scripts? Here is an example for the trim function of the internal preamps:
ext/<ibank_or_obank>//ch//trim
Type: OSC float32 ‘f’
Available since router version: 0.0.0
Description: A dB-value for how much to trim this input or output channel. The range of this parameter is indicated by
ext/<ibank_or_obank>//ch//trimRange. Only available for certain input or output channels.
ext/<ibank_or_obank>//ch//trimRange
Type: OSC float32 ‘f’
Available since router version: 0.0.0
Description: A pair of the minimum followed by maximum values allowed for the trim parameter on the input or output
channel

I Honestly Have no idea if i need these to control it from gig performer or if they can even commuincate.
I tried reading the scripting manual last night but I was too tired to make any sense of it

If any of you have a idea what I need to do please help!
