Miracles and Raindrops is a great tune, I did not write it unfortunately, it was written by Scott Osteman who lives in Omaha, NE. He is now the lead singer for a band called Echobliss.
As for your question about the pedal, I hook it up to the output of whatever sound device I am using. Basically I run from my Zen MIDI out to the sound device MIDI in, from there I use the 1/4" cable out to the volume pedal, and from the volume pedal to my amp or to the PA mixer. That is it. My main purpose for using the MIDI foot controller was to be able to switch between kits for different pad assignments without taking my hands off of the Zen to use the cursor on the back side. For example, I was using my Roland TD-6V, great sounds, it has limited trigger assignments so I could only crossfade a couple of pads before taking up all of the trigger spaces (it was only a drum module restriction, nothing to do with the Zen). The reason for me switching was I may want a side stick for most of the song, I would program kit #2 on the module to switch the snare out with a cross stick and I am good to go. I may want toms in kit #1 and I could put congas in kit #5, I can go straight to kit #5 by just pushing the #5 button with my foot and not scroll up 4 times on the cursor on the Zen. My TD-6V just didn't support MIDI volume control so I had to purchase a volume pedal with 1/4" inputs and it has worked great.
As for which sounds I use now, I was very content with using my TD-6V, the sounds are great, it is small and not very expensive, plus it came with my electronic kit. I did buy a second one for a backup. I had thought about using something like BFD2 but I was hearing about how complicated it can be when getting up to speed on it. Just this past week, "The Mayor" Tom Roady came by for a visit and he set up some of his “toys” and I hooked up my Zendrum. He was using a Macbook, GarageBand, and a program called EZdrummer. The sound quality to me was night and day, there is so much more control with what you can do with your kit using the software, and I am hearing that BFD2 is a memory hog so you need to compensate your computer to handle that issue.
I went out that night (with my wife Lisa) and purchased Superior Drummer which is basically EZdrummer on steroids, and several of the expansion packs with many additional kits, and a Macbook Pro with 4GB of Ram to make sure I had enough memory to run what I needed. Basically, I am only using Superior Drummer for my sound module now, I still have the Roland when I play and have a setting mapped for my it on my Zen in the event my MacBook isn’t working one night, but my TD-6V stays in the case as an emergency backup. I suppose I could hook them both up together but there is in my opinion a significant sound difference between the two and I don’t think they would match up, and the Roland is very limited compared to Superior.
GarageBand is basically a mini recording studio on the computer with piano, guitar, bass, and drum sounds. You can control them from you Zen and basically create an entire song with the Zen. You can add multiple tracks and control many things for each track. I haven’t played with GarageBand much yet, but I will in the near future. I am playing a gig this weekend and will be using Superior Drummer instead of the Roland, I bought it last Friday, had a basic kit setup in less than an hour to include congas, rim shots, and chimes with my full kit. Went and played with the Mayor and some of his friends that Sunday and it sounded like I had been playing with that program for years. That is how easy it is to set it up. Just this week I have tweaked it even more and played with some the EQ and velocity controls in the program and haven’t had to touch anything on my ZX except to move pad assignments around to fit my style. I definitely recommend going with Superior Drummer, although I have no experience with BFD2 other than what I hear from other users.
Hope this answers some of your questions, and sorry for the long post.
