Idea: Automatic Drax song generator compo.

Speaking of randomization of music on the C64; In Essentials I did a kind of hack that randomly imposes algoritmic variations on top of the original Druid II tune/player. It is obviously primarily meant to be spaced out, than "good", but still an example of random variation within certain constraints. You can control how much randomness is imposed by dragging the bar further to the right. At the leftmost side no randomness is imposed, and at the rightmost side there is quite a lot of weird stuff happening. (The randomness "engine" is built on the same principles as the code that generate a lot of glitches on top of the Hat Trick game in HT Gold with different "layers" of random tweaks that operate separately, and therefore potentially also on top of each other, at the same time.)

Some other time I did a random music generator for one of those 256 bytes player compos: Block Acid Dub [254 bytes] In this case it is mostly drums, bass and various bleepz.

Something like an endless random pentatonic lead over a random blues scheme shouldn't be too hard to do, even on c64 :) And the result shouldn't turn out too shabby either (probably no different to many existing tunes which are basically just that)

Please explain the research, because visuals and audio only doesn't make me understand tbh. Anyway, please keep up whatever floats your boat.
