Pop trivia questions - I'll be impressed if anyone knows answer to these :)
- How many possibilities of 7 tone scales exist in 12 tone music. (exclude modes)

792...

I remember learning about the 'Circle of Fifths', but it was centered around the different alcohols that went into a Long Island Iced Tea.
 
It was much later that I got the 'corrected' information on that from theory classes as a local college and private lessons.
 
Who knew?  :)
 
Thanks for the tip - I LOVE the Coursera offerings - there are a bunch of other free classes at a whole bunch of other online universities and such.

Is an augmented fifth the same as a fermented fifth? I think I need to brush up on my alcohol theory.

I probably should have been more clear but exclude modes, transpositions of the scales, and scales that have 2 or more consecutive semitones in the result. The latter yields scales that are less harmonically "useful".
i.e C maj and D dorian, C# maj should be treated as the same basic scale. There is a bit more to it than just permutations :)

So I'm going to take that as a big no!!😃😃😃

It could only be 1. All major or minor scales has 2 consecutive semitones. The only one that has not consecutive semitones is the whole tone scale.

I had my time studying theory in college. I have to say I liked it much better than algebra  After my 5 years at it the way I understand music theory is that music composed before now and the practices they used to make compositions are guidelines set forth for me (you) to use for direction and example  (what they did) Music theory comes after the music is written.  Theory helped me understand instead of using 135 for a triad and chord scale use 127 then build from there kind of things. It's one of those things you gotta have, like practicing to get chops. It's the end result that makes it worth the time!

Then the answer is : 6
And 4 from them have one and half tone interval (you have not mentioned that is not allowed).
Still calculated with pure combinatorial approach... 

Exactly correct! 4 of them have minor third intervals in them. Color me impressed :)
I'd be interested to see how you calculated the answer. Did your method also allow you to list the scale contents or just compute the final count of scales? Two of the scales in this list are not traditionally known.
 
PS: Your ACT controller looks interesting. Did you use the new control surface SDK's that we posted recently to help build it?

The same way as you originally, small C program. I have realized that analytical approach can take more brain activity and I need the program to check results in any case. It was not working the whole night so, my laptop is faster then Z80. In former time I could white it directly in codes, but with age I prefer to use C (or assembly for system toys )
 
To be fair, I must say I could not foreseen the existence of scales with minor third till I saw them printed.

I use IDL only (manually converted to C). My whole code is in C (not C++), compiled with cross GCC under Linux. I have not used new COM interfaces yet. I have tried "StepSize", but it is not really working as I expected.
 
Sorry for off topic, but since your are "here"... There are several threads about PC in Mackie plug-in. I do not have such device, but I am just wonder why it is not "work arounded" in plug-in till API is fixed in SONAR? May be it is already done on github, I have not checked, but in case it is not I can write the approach I have used.

Indeed,  doing it analytically demystifies it. It was a revelation to me when I first did this.
Minor thirds are common. The harmonic minor and harmonic major both have this intervals.
 
Regarding the surface stuff, you did it the hard way :) Its much easier to start with the C++ ACT control surface and work from there for most people, I would think...
Regarding Mackie, not sure which issue you are referring to, but the surface is not act aware. So it would need to be modified to handle that. Feel free to try adding support to the surface on github. You can refer to the VS700 or one of the other surfaces to see how its done there.
