I have a home recording studio with ProTools HD. I use a Kurzweil K2600 for drum, bass, and keyboard tracks, and I mic vocals and guitars. I create MIDI tracks in ProTools, then sequence with ProTools and record the K2600 audio output into audio tracks.

I have numerous CD-ROMs of Programs for the K2600, so I have a good variety of sounds available from the K2600. But what I lack are libraries of grooves in MIDI format. I only have Drumtrax 3.0 for drums, and I have no libraries for bass. Drumtrax is terrific; I can easily import the desired MIDI files into a ProTools session and then modify as needed.

Where are the best sites for locating available MIDI files for drums, bass, and keyboards?

Thanks,
Sherwood
