Amazing, how sometimes the answer comes to you when you simply stop thinking about it. When I woke up this morning, I had an idea. I figured I could still get some of what I need out of the Quad switch just be reconfiguring my existing patch map.
I have a few patches with a 'dry' and 'wet' variation, but using pretty much the same reverb. These two patches can be combined by simply using the Quad switch to turn the MP-2's chorus on/off. I just gained 4 patches right there
I can also use the Quad switch to turn the Effects Loop on/off, which gives me a few more free patches by combining my existing 'clean' and 'delayed' patches. I saved one patch with a quick delay, one with a long delay, and I still have a 'wild card' patch for specific songs that require that.
For now, here's how I have my Quad switch set up:
1 = F/X Loop in/out (allows for Clean/Delay)
2 = MP-2's Chorus in/out (Wet/Dry)
3 = MP-2's Compressor in/out (I use the Comp's gain as a solo boost)
4 = MP-2's Wah in/out (triggered for an Auto-Wah)
I had some difficulty getting the Quad switch to switch the F/X loop in/out using switch one, in the Pedal One jack (program #64). No matter what I did, it simply acted as a mute...I seem to remember it being set as a tuner mute by default, but I went through all the settings (including the program numbers) and it didn't work. I resolved this by plugging into the other pedal jack and using program #s 68-71.
EDIT: I found that CC #64 is the default Tuner Mute location, per the MP-2 owner's manual, page 49, bottom of the page.
