Digital Scale

• Note: So you, the Reader, won't be frustrated after reading this, what I discovered (below) didn't work. I'm simply explaining the details of what I went through, in order to find an "alternative", hopefully "better", Music Scale… but I didn't.

I had been thinking about Alternative Tunings for Music for several weeks. I even did a lot of research to see if any of the current Eurorack, Modular Synthesizer Modules would allow me to actually pick my own "Frequencies".

• There are lots of Oscillators and Sequencers, which allow you to "manually" set their "Frequencies" but getting them to produce those same exact Frequencies every time, is not something I found while doing my research.
• Yes, there are Modules called: "Quantizers", which will align every Pitch, Voltage and MIDI Note, coming into it, to the closest "Note" in its Scale. However, in "my" research, "most" force you into selecting from a list of Pitches which aren't broken down smaller than quarter-tones.
• I only discovered 2 Quantizers which allow you to select your own Frequencies but they seemed to be a bit difficult to program. One is the "Disting Mk4" ($189), by "Expert Sleepers", and the other is the "µTune" ($299), by "Tubbutec".

Several weeks ago, I was thinking about the "A equals 440Hz" (Cycles-Per-Second, Frequency) and that some say "A" should really be set to 432-Hz.

As I was looking at those numbers, I noticed that they are "8" numbers apart from each other. Since I used to do some very basic programming, a few decades ago, my mind instantly thought there might be something to that relationship…

• Since "Society" has been lied to in so many different aspects of this "Reality", what if those "liars" knew the core Frequency for Music should be "448Hz" and, in order to mislead everyone, moved the number "down" 8 Cycles-Per-Second (making it "432"), to throw us off track, instead of "up" 8 Cycles where it should be (making it "448")?

From there, I did something "thinking" and some "math" and settled on the number "32". Computers are based on multiples of "2", which are "zeros" and "ones". Home computers in the early 80s had 8-bit Processors, which is a multiple of "2". I settled on "32" because "2", "4", "8" and "16" Cycles were too close to each other for my note-building exercise. 32 seemed to be the smallest number of Cycles-Per-Second which the Human ear could distinguish a difference in Pitch AND it would take-up an entire Music Keyboard, just to have at least 2 "Octaves".

I left "A" at 448, as a starting point. I then "added" 32, to find higher Notes or "subtracted" 32, to find lower Notes. This gave me these Frequencies:

• 128, 160, 192, 224, 256, 288, 320, 352, 384, 416, 448, 480, 512

Since I couldn't find any "easy-to-use" Synthesizer Modules, which would allow me to enter the "Frequencies" I wanted, I did some testing. A few days ago, I used "Audacity" (audio manipulation software) to produce those 13-Tones. I was going to load them into Apple's "GarageBand" software, in order to move them around and stretch them, just to see if this new "Scale" would sound good… or not.

That quickly became a bit complicated so I stopped.

Today, Sylvia reminded me that our Korg Krome Keyboard offers Tunings and Scale creation. So I checked the Manual and turned it ON. It was a bit tricky and did take me a few hours but I was able to set those Frequencies.

• The "tricky" part was that I had to use "Audacity" to play each Pitch in a loop, while I found the closest "key" on the Keyboard to that particular Pitch. Then I adjusted its "Semitone" setting until they sounded the same.
• When I was done, that "Scale" was spread across 2, standard Octaves on the Keyboard and used both the "black" and "white" keys but not all of them were next to each other.
• I marked them with small pieces of Post-It Notes, so I could see which "physical" keys were part of that "Scale". I even recorded a low-to-high "run" of Notes into the Krome, in order to hear it played back smoothly at different Tempos.
• I then tested this "Scale's" Chord capability. It was difficult listening to the "run" of Notes, because they weren't too pleasing, but the Chord possibilities were even worse. I found 3, maybe 4 combinations of Notes which sounded "ok" together.

So, other than "I just wasn't happy with what I was hearing", I began to wonder… "why"? Is it because those are simply Frequencies which work against each other or is it that my brain is programmed to identify certain sound combinations as "good" and others as "bad"?

In doing my 1st calculations, I took used the "Note-to-Frequency" Chart on this page:
https://pages.mtu.edu/~suits/notefreqs.html

I then plugged those numbers into the Frequency-Semitone calculator on this page:
