Gear, Just a thought: You could market the program through Renderosity's online store. They have a few other "programs" for sale there. It would be a low overhead startup. Is there a problem with your licensing of the core "midi" code? With Bryce 5 and Poser 5 on their way, this might be a good time to get your program out, before someone else or the new Poser/Bryces beat you to the punch. If it is truly possible to do, as you assert, then someone else will do it, especially if you don't. You have, afterall, revealed here a unique and basic approach to solve the problem. We don't need "no" fancy interface--just something that works. Put my vote in for a PC version. Any feedback here would be appreciated. Again, good luck.
