So, you're asking if you should go "full midi" in that you don't want to be changing any of your sounds using anything but a midi pedal of some kind?
I've never quite gotten there myself, although I have similar gear to yours.
Here's my rack, but I recently changed out that Delta 1010 with an MBox Pro:
Here's my midi foot controller:
Now, I've got a couple of guitar amps, the Carvin MTS 3200 100-watt 2x12:
I've also got a Peavey, but no picture.
I've also got (as you can see in the rack) the TC Electronic G Major. I love that thing!
I've got all 10 of my preset buttons on my controller set to various effects and combinations of effects.
The only thing I haven't been able to do is switch the Carvin between the clean and distorted channels using MIDI so I still use a mechanical foot switch for that.
So, what you're tying to accomplish is to get ALL of it running through a midi controller, including changing from clean to distortion on your amp?
