And Musagi, don't forget Musagi.
Speaking of which, while we're on the topic: Can I really get that much more out of using a 'professional' program like LSDJ rather than Musagi? What are the benefits?
I take it you want to make chipmusic only? The only real upside with LSDJ is that you get the real hardware sound (if you have the real hardware). I personally find it user-friendly but I know for a fact it really isn't.
If you want to make anything other than chiptunes (heck, even chiptunes) try learning a Digital Audio Workstation, a DAW. Reaper ( http://www.reaper.fm/
) is free for non-commercial use and both good and deep if you want it to be. Using plug-ins and samples you can achieve pretty much any sound, no need to limit yourself to a closed platform that might require more effort than it's worth to achieve a "realistic" chiptune sound.
Then again, you can always contact any of the gazillions of musicians looking for work or even free collaboration.
