I was thinking to make handmade hero completely procedurally generated the music should also be generated. Not fully generated because that doesn't seem feasable to me, but the various areas of the 'overworld' like (I'm guessing here) dessert, rocky, swamp, forrest could each have a set of baseloops and melodyloops that represent those area's. And maye two types of sets, 1 normal set and 1 agitated set for when you're fighting. And maybe a set of trigger loops to move from normal to agitated and back.
So for an area randomly select 1 or 2 of the base loops and sprinkle this with melody loops over that. This way the sound can be done the same way as the ground swatches and grass tufts are done currently.
Don't know what Casey has planned for music, but it would be nice to have musical variations as well as world and game variations right.
What do you guys think?
