MultiBall Parametric EQ

First - Lemur is exactly the interface I've been looking for! Thanks!

I want to control a 3-band semi-parametric (no 'Q' setting) eq on an old guitar pedal. Here's the parameters for each EQ:

Amp Channel 1
Low EQ- Freq: 50Hz - 300Hz (CC38) / Gain: -12 to 12 (CC39)
Mid EQ - Freq: 300Hz-5000Hz (CC40) / Gain: -12 to 12 (CC41)
High EQ - Freq: 500Hz - 8000Hz (CC42) / Gain: -12 to 12 (CC43)

Amp Channel 2
Low EQ- Freq: 50Hz - 300Hz (CC51) / Gain: -12 to 12 (CC52)
Mid EQ - Freq: 300Hz-5000Hz (CC53) )/ Gain: -12 to 12 (CC54)
High EQ - Freq: 500Hz - 8000Hz (CC55) / Gain: -12 to 12 (CC56)

The best/cleanest answer in my mind is to make three separate MultiBalls (one for each band) with 2 balls in each (one for Channel 1 and one for Channel 2). For the first MultiBall (I called it "LowEQ"), 'x[0]','x[1]' would be Channel 1, Channel 2 Low Frequency respectively. 'y[0]', 'y[1]' would be Channel 1, Channel 2 Gain respectively.

I've figured out how to display the converted values for each parameter as part of the MultiBall labels and how to make sure they update when the Mulitball is moved, but, how do I assign the Channel 1 and Channel 2 Midi outputs so that LowEQ.x[0] is tied to CC38, LowEQ.y[0] is tied to CC39, LowEQ.x[1] is tied to CC51, and LowEQ.y[1] is tied to CC52? I've poked around on the forums and am still a bit confused! Also, if anyone has a better/cleaner way to do this, let me know! Thanks!

Attach your "up to now" template so that we can get it done! ;)

I think I figured it out. :D

Here's where I am so far, still need to test it with the pedal to make sure my "500Hz" = the pedals "500Hz"
