If anyone is curious for the context, I'm thinking of upgrading the Compiano Forte. I want to build a more advanced sequencer for the microfreak, and I also want to have a common graphical shell for my midi experiments that can be operated with just midi controls or a game controller.
For the sequencer, what I'd like to do is to build something that functions similarly to the microfreak's internal sequencer but with more parameters, the possibility for much longer recordings, and some cool options for track changes. Once I'm happy with the patch and the score, I'd like the program to then play the tracks and record them for later mixing. After that I'd change the patch and build additional instrument scores with the same method.
