This could be used to assign midi notes to keys either for producing files or performing, using some other input to handle velocities etc. [I expect to use a joystick for volume, tempo -- and to add a smaller table to associate these numbers (mod 7) with whichever scale I'm using at the moment-- with joystick buttons to modulate in real time...]

ie You can use any arrangement of keys you find useful, not necessarily chromatic, not necessarily linear!

If the subpatch doesn't load, please ask!

Oops, sorry!

[A simple little gadget I thought I'd stashed in pd ro-file, sorry. Lets me connect some wires in a non-obtrusive way and take the final value out the right outlet.]

You'll want something like this (if I've gotten it right) to use the keymap table with midi;
instructions should be (?) in the subpatch pd how-to-use...
