latest album is hand composed I think (in weird time signatures/combinations of time signatures though), but the stuff immediately before that was made by a custom algorithm in JS. From "digi analog abacus tone poem qualia" to "some say he just kept driving till the Lazarus ran out", and earlier stuff too but that whole string of albums was made algorithmically.
The weird thing about the algorithm is that it uses something called the Cayley-Dickson Construction, which is like QUATERNIONS but extended further to 8, 16, 32 variables etc.
so the thing about this, in the 16 variable case, it's used as a 16-step sequencer, so on... so would the music still be in 4/4 no matter how abstract?

) just a weird thought
I was going to maybe post the MIDI code in the Reaper JS forum but they despise me over there, so I dunno
