I've currently been researching using a MIDI setup for my amp and was looking at the lexicon mx400 multi effects. I was planning on using the multi fx bypassed most of the time but adding mainly reverbs and delays from the mx 400 for solo's and leads (I play mostly metal, so im not looking for a setup where i need to switch from cleans to distortion instantaniously.) So if I used the MIDI out on the mx 400 into just a MIDI footcontroller would that be all i needed just to switch the Multi FX from bypass to whatever presets I have on the mx 400? Also if anyone knows a good site to learn more about using MIDI for guitar rigs that would be great.
