Hm... let's see. This thing is supposed to output between 100 Hz and 10 kHz (it's not exactly sound oriented, i'm just making it that way because tones are easier to deal with when I don't have an oscilloscope).
My first thought was to have the top eight switches be a multiplier and the bottom eight be a divisor, but that's awkward to actually implement. so's any kind of irrational ratio (wow, dumb phrase, me) since i ain't got floating point.
the range is 6.something octaves so i can have the top three switches do a straight octave multiplication...
as far as i understand this syntonic thing, everything's just a product of octaves and perfect fifths? i guess i can pull off 3/2 ratios. this board has like three hundred multiplier circuits, surely i can do that
the next project is an actual musical synth, hooking up the board to a computer keyboard. there's some frequencies laid out (12-TET ofc), i wonder if anyone will care if i do some weirder bullshit there
Yeah, 3/2 is a fifth, 5/4 is a major third, 7/4 a minor seventh, and that's just harmonics. To get the inversion of an interval, just flip the ratio and multiply by two: A fourth is 4/3, etc.
I soothe myself by wrapping myself in blankets and feeling the sun on my face.
Some soothe themselves by spinning, some with rocking chairs, some with chants and song.
Some count, some walk, some chew, some imagine; I see nothing wrong with self-soothing (within reason), it is natural and the methods available to neurotypicals may not work so well for those of us on the Autistic spectrum; you don't have to deny yourself something that comes naturally to neurotypicals; that's what the rights are all about.

i know that, i'm talking about this harmonic system in particular. e.g. to get a third wikipedia suggests four fifths minus two octaves (so (3^4/2^4)/2^2 = 81/64.
going off of the 5-EDO mention.
i'm pretty sure i'm misunderstanding a lot of this. 31-EDO's article says it's the same as 31-TET, and uses a 2^1/31 ratio which sure isn't a perfect fifth or octave...

Stick 2^(1/31) on top of itself 31 times and you get an octave. Eighteen of those steps is damned close to 3/2, and ten is nigh-indistinguishable from 5/4.
You can get about as close to 5/4 if you stack eight pure fourths—(4/3)^8—which is about 1/53 of an octave flatter than 81/64, which is noticeably sharp.

well, sure, but i figured syntonic meant actually just using 3/2 2/1 ratios, like ol pythagory
I don't think there are any riffs on it, just waves of incoherent noise. It's pretty cool
Check out Xaman. It's basically just a series of awesomely heavy bass riffs with crazy guitar sounds and huge drums on top, with the occasional incomprehensible screamed vocal.
You will want to either seek out the reissue, which was originally part of the Kino box and is, if I am not mistaken, delightfully pimped out, or just nab a rip of the original CD online, because getting a physical copy of the original CD version that is actually playable is probably impossible.
it's fun to think of features though. for now i'll do 12-TET and bending. probably not enough interface to draw waves, but i can have it select from a few... maybe i can figure out harmonics too

That's what I meant when I brought up the fact that eight fourths makes a near-perfect major third. That's a classic trick of Pythagorean tuning. Meantone operates on the principle of simplifying the process by reconciling 5/4 with 81/64 or 5/3 with 27/16 or whatever. 5-, 7-, and 12-EDO are reductio ad absurdum of those qualities.
alright bitches i got half a synthesizer. someone give me ideas for how to turn sixteen switch inputs into a musical scale. like, this combination of switches is A on middle C, this other one is some bass bullshit, etc.
Oh, that's easy. Just use the 16 switches as a 16-digit binary number.
0000000000000000 = some really low bass 0000000000000001 = that bass Sharp hell, just keep that first digit as the halftone (sharp), since like, Csharp = Dflat, if i recall correctly.
and then output the result to some speaker that just goes BZZZZZZZZZZZZZZZ endlessly in whatever tone you picked
EDIT: people who actually know and/or remember music answered already. i didn't realize this was 3 pages ago. i have been endlessly owned.

music is all about fiddling with the settings in a 7-band graphic equalizer for hours on end

I can hear that old television noise at 16,384 Hz. It is Hell.
It happens.
What about starting with a sick riff and just riding it into the outer darkness with the power of rock?

i'm running this shit with a window frequency of... fast... uh... 390 kHz. can't hear that shit, no way no how, what did i fuck uuuuup
i guess i'll just hook up a keyboard and work it out later. maybe i fucked up my wavetable who fucking knows

disc rot sucks
Spend some time doing things you like, maybe?
i'm sorry.
i'd send you the thing anyway but i need it for class and also it's like two hundred dollars new... though i do have an older model, hmmmmmmmmm

Goodnight, folks.
i feel like i'm about to lose 2 days
i say that like i ever do anything worthwhile with my time
