Kevin, if by cajon you mean those little box drums you sit on and play, I have looked at those. BUT, I really don't want to learn another instrument. That Roland SPD-20 sounds interesting though. I'll have to look into that, or some other type of drum machine I can get different, simpler drum patterns from. One other thing about my drum tracks is my Yamaha actually has the entire rhythm section; Drums, base, other instruments. All I can do is drop specific sounds out and set the volume for the ones I do want to record. I tend to record the drums and a base sound, which all ends up on one track. I can control some of the drum instrument volumes, and as soon as I get my latest song done, I'll upload it. The shaker stands out, and a slight drum beat will be in the background and almost no bass. The dood news is, when I master my song I can completely drop out the drum and bass.
