Re: [chuck-users] semi complicated midi setup

I'd like to control chuck from my 3 usb keyboards. Preferably with the abiliy to split one or more of the keyboards to different sounds, dynamic voice allocation is a must for polyphonic sound.

I'd like to make the code as modular as possible, in order to easily create one such setup for each song. This means that the definition of which keyboard(s) is spilt and how + routing to actual instruments + code for each instrument should be in seperate files.

I'm still very new to chuck, so my first question is simply: is this at all possible with chuck?

Yes. To use chuck with multiple files, include them all on the command line. ie $ chuck foo.ck bar.ck

The second question: (if possible) could soneone provide a rough outline, how to achieve what I'd like?

The beauty of a language like chuck is that you can solve any problem in many different ways. I don't think this is the best solution, but it's the easiest to explain: 1) get MIDI information from keyboard. This is covered in the manual. 2) Look at the midi info; if ((notein>x)&&(noteinz)&&(notein std.mtof(note); 1=>foo.startStuff; // I can't remember if it's noteOn or startBow or whatever. 2::second=>now; // or however long you want this to be... you could certainly write this to stop when you receive a midi note off, but that's left as an exercise to the reader. :) 1=>foo.stopStuff; } That should be enough to get you started.
