Reply to Custom Firmware?

Hey everyone,

I recently upgraded to the 1.3 firmware. Its totally awesome but there are a few few minor things would like to change. It looks as though I would need to change the firmware to do it and so I was wondering if anyone had taken a stab at editing/creating firmware.

Specifically what I would like to do is:
1. turn the filter button in to an on/off button as well
*This may be doable in the TKS but I have not had any luck

2. change what effect is selected on effects bank A
*If I am reading the MIDI correctly, Ean achieved the fx select button by tuning them into knobs with a specific value corresponding with the fx. this is where I am almost certain I would need to get into the firmware to change. I mostly use Reverb and B-Mash so i would like to move the B-Mash to FX bank A.

Thanks for the help guys
