OSC multiple volume faders?

[J Riley Hill]

Hello

I've been mucking about with creating my own OSC control surfaces lately using TouchOSC and I've been able to do some things I wanted too.....

but I've been unable to discern from the instructions how to create a layout with multiple volume faders. I have been able to figure out last touched volume, last touched pan etc, but is there a way to have a "bank" of say 4 or 8 fader?

If anyone more familiar with REAPER OSC could point me in the right direction or share an example file it would be much appreciated!
Thanks
