Good point winger!!!

I've thought in using, but as I'm Brazilian and its very easier for me to get the percussion instruments I like, and as I'm those kind of drummer that likes the sound, feeling and visual of the real instruments I never used a pad, also, because many of those instruments has a vast dinamic and "playing surfaces" (AAA, I hate my english ) and I never found a pad with more than two triggers...

I use a Roland SPD-20 to add extra percussion to my kit.

Using DDRUM triggers, I trigger all my drums (6). Since there are only 4 inputs on the back, I added a Roland TMC-6, which provides a total of 10 trigger inputs. Have a PD-5 and a PD-7 for things like COWBELL (hi, Louis!). Use a PS-150 piano pedal for program changing.

Sounds can be layered. The electronic drum sounds match the acoustic drum sounds in pitch. There is a second layer matching the pitch, but the sounds run backward. It's a neat effect.

My fav is layering the floor tom trigger with a tambourine. Very effective with 8th notes on the floor tom. People look at me and wonder where that sound is coming from. With some of the other sounds I can get, folks have asked "where's your keyboard player?"

The percussion possibilities are endless. True, it's not the same feel as a real cowbell or any other acoustic instrument. Due to limited setup times, it puts a wide range of percussion sounds at my fingertips without having to lug the instruments and set them up.
