Ken,

I'm sure you can connect the speakers to your 3000, but unfortunately, I'm not familiar with that particular system.

As for finding midi files, the best search engine for midi files is www.musicrobot.com which will usually list huge numbers of song files of various lengths. If you're looking for midi files with imbedded lyrics, check out www.vanbasco.com for them.

Good Luck,

Gary
