OT: Arranging Background and Comping Figures

[Rick Sutphin]

Hello,

This question is off topic, but I thought the posters to this newsgroup 
might be able to help.

I am a bad multi-instrumentalist with a multi-track. I would like to 
record accompainment grooves in various style to practice with (playing 
all the instruments myself). Not only am I a bad multi-instrumentalist, 
I am a worse arranger/composer. What I would like to find is a source of 
typical rhythm figures/comping patterns for different styles. These are 
easy enough to find for bass guitar and drumset/percussion, but I have 
not found anything useful for guitar or keyboards. Horn section patterns 
would be a plus.

Thanks in advance, and I again apologise for the off topic post -- 
though I do use Lilypond for all of my music type-setting :)

Rick
