Yamaha DTXpress/DTXplorer/DTXtreme

Hi Keith,
I really appreciate all the research you've done on this, but I'm 
just going to take the cowards way out and buy a proper Yamaha 
peddle. Maybe some cold winter day I'll experiment with my existing 
peddle, but for now, I just want to get playing.
Thanks again.
