how can I block PC messages sent from FC1 to hardware synth

[Will Robinson]

Im using FC1 to control hardware synth (Boss GM-800) in 'hardware mode' via the 5 pin midi out. I have two FC1 presets that are the same except for the pitchbend setting Trigger vs Auto.
 So when playing a traditional keyboard instrument, piano, organ, etc I get the individual semi tones triggered in an authentic way. I switch to the other FC1 preset to have smooth transition in pitch for synth type sounds.

The only problem is, when changing FC1 presets, the FC1 sends PC change info to the hardware synth.
Can I set the FC1 to not send PC and still continue sending all the other info, midi note, etc etc?

The GM-800 Tone Studio does not seem to show an option to switch "off" received midi program change,
 so your only options are to either stop P.C. messages sent from the Fishman TP, or use a midi event filter hardware device.

One technique you could use for the wireless controller would be to stay on the same FC-1 preset, and instead use the "Exit" button (the button on the 4-way that is closest to the volume knob) to cycle between the four bend modes; it will change in this order: auto->smooth->stepped->trigger->auto. The "Enter" button (the button on the 4-way that is farthest from the volume knob) will toggle between Mono (each string on a different channel) and Poly (all strings on the same channel) mode.
If you are using the wired version of TP, you can do a simultaneous press of Up + Down and it will toggle between Auto and Trigger bend modes.
You could also make a bunch of presets (which we call hardware patches) that each select different sounds on your hardware synth, and that way the bank selects and program changes will be actually helping you.
Gumtown's suggestion will work as well.
