Ok, after a reboot of my iPad, I was finally able to load the layout. (Prolly inflated the download count by about 10 by now)
As suspected, the designer hard coded the midi channel (1) into each control. Your option is to edit each control to change it to channel 16 - see picture below
The quick and easy way is to use Streambyter rules to intercept and change the outbound message. (You will need the optional streambyter rules IAP.) Looks like the designer used only control and program changes, so we need two translations:
This outbound rule will change control and program changes from channel 1 to channel 16: (B_ is control changes, C_ is program changes, _0 is channel 1, _F is channel 16)
B0 = BF
C0 = CF
Type the two lines in the More / Config / Connections / Output Rules Streambyter box, press install.
I did not see that the layout received any info from the pedal, but if it does, you need the reverse rules on inbound:
BF = B0
CF = C0
My one worry is that your FB post yesterday showed some channel 5 data, and I don't see any channel 5 controls in the layout.
