Now even more interestingly, my program also deals with music! :) I'm
generating microtonal midi files. I use it for very much the same purpose as
you do (although my program is not yet finished).
Is it something we could and should add to Haskore?
If Haskore could support microtones that would make this world a slightly
better world for me. Here are the basic things you need to support
microtonal music:
- Pitch representations would have to be able to express any pitch.
- One appealing approach is to represent a pitch directly as it's
frequency.
- Probably the most useful representation though is a base pitch,
say one of C,D,E,F,G,A,B, followed by a list of accidentals that
modify the pitch. The user should be able to define his own base
pitches and accidentals, in terms of cents or frequency ratios or
something similar.
- Generating microtonal midi files requires that you add pitch-bend
messages before all notes. That restricts each midi channel to only being
able to play one note at a time. This is a big deficiency in the midi
protocol imo.
