Right now I'm working on the music for a video game that will come out later this year on Sony PSP and Nintendo DS. I don't think I'm allowed to say just yet, which game it is, but it's going to be cool. :-)
I'm making the same music tracks for the Sony PSP and the Nintendo DS platform, but I have to do the work twice over, because I have to create the music in two completely different formats. The Sony PSP can "stream" the music from disc, and that means that I can record the music using normal instruments and all my studio equipment etc. But the Nintendo DS doesn't have anything to stream from, so I have to create the music in good old "tracker" format (in this particular case, ImpulseTracker format or FastTracker format).
I'm using a program called MadTracker, which allows the composer to "program" the music using a complex grid of letters and numbers. It's how it all started for me, on the Amiga computer back in 1988, I used this kind of system to make my very first fumbling musical steps. And here I am, 17 years later, back to using a music tracker for the music on the latest Nintendo handheld. Who would have thought it?! :-)
