Hiya, Pastor! Don't be "freaked", its just my nickname. I didn't even choose it, it was conferred upon me! Don't ask! If its of any comfort to you, I have a great bumper sticker that says "Satan Is A Nerd!"
First, go to keyboardmag.com and check out their resources. Its a very straightforward and informative magazine & their website has archives & info you should check out. They also have an internal search engine that will enable you to look up old reviews as needed, text-only.
A couple of years ago, they did an entire article on the available 3rd-party M1 sounds and the back issue should be available for $10, I believe. If you can't get it and want it, keep my address handy and I'll photocopy the whole thing for you. No problem! I also have the original M1 review they did, if you like.
Next, check out their classifieds, which offer sequences, sounds, etc. In particular, kidnepro.com will have a fair set of M1 sounds if you want to beef up your library.
Then use a search engine and enter "Cubase synthesizer Cakewalk Voyetra Steinberg software," which should lead you to a BEWILDERING number of sources. While I choose to live within my Korg sequencer's environment, I'm led to understand that there is a good "Cubase Lite" program that will get you rolling without the esoterica of more complex programs for film soundtrack pros or what have you. I have a friend who raves about Cubase, so its a tip to consider. Again, Keyboard mag. is a great place to start. Hope this helps you out.
