It looks like you have got some great info already tributeman, so I will just add this..

Using a Soundfont will improve immensely the sound you here for a Midi track, this you will have more inspiration to work on the tunes, and that can only help out your songwriting.

There a are a TON of SF out there, and Allanah's site has some good ones. Just remember to grab the GM Soundfonts only, this way everything will be set up & ready to go. If you grab them a single instrument at a time, you will have to "map them" to the right channels.

I like the 037.4mg Personal Copy v4.0.0 Bank for general backing tracks. Tho it is a large download, I think it is worth it.
