Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Well done Nick! Before anyone else has a go at it (I agree the Stoic right scrolls can be improved), would you please copy the middle-of-three-right-scroll and the middle-of-three-left-barb to become unencoded components, and include them in all the Stoic symbols by reference only, with appropriate ...

Re: 270edo in athenian+trojan only

As you may know, George and I agreed on the following notation for 183edo: 183: :|(: :~|(: :/|: :|): :|\: :(|(: :/|): :/|\: as given in the Scala file https://sagittal.org/sag_et.par Interestingly :)|(: rates higher than :~|(: , and it has lower fifth-slope too. Why isn't 2\183 :)|(: instead? Good ...

Re: 270edo in athenian+trojan only

I found an email to George in 2014 in which I wrote: "There are also several [EDO notations] that I believe we have agreed on that are not in the XH article or in Scala. These are 270, 282, 306, 311, 342, 388, 494, 612, 2460. These should be added to the Scala sag_et.par file." But we neve...

Re: 270edo in athenian+trojan only

Thanks for those. I haven't had a chance to think deeply about them yet. But here are a few shallow thoughts: I note that the Stein semisharp :>: is available as a forum smiley : >: and the narrow semiflat :<: is : <: . When editing a post, if you click on "View more smilies" you'll see th...

Re: Semaphore / godzilla

Hi Keenan. Welcome to the Sagittal forum. Here's a mapping from Graham's temperament finder. Reduced Mapping 2 3 5 7 11 13 [ ⟨ 1 2 4 3 6 6 ] ⟨ 0 -2 -8 -1 -12 -11 ] ⟩ TE Generator Tunings (cents) ⟨1204.4822, 254.5504] Semafour+, the 13-limit extension of semafour [sic], has: Reduced Mapping 2 3 5 7 1...

Re: general methods for linear temperament notation

I notice that he not only uses the same notation |a b c ...> for prime exponents and generator counts, he doesn't use plus signs and he even calls the latter "tempered monzos" — yikes — helping making my case that Gene's monzo/val terminology is unhelpful and just raises a barrier to entr...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

I meant to say that I love your latest 8 ppss bitmaps, except I would make the 12 dent symbol wider, and more symmetrical about its staff position as follows: https://forum.sagittal.org/download/file.php?mode=view&id=359 I also meant to tell you that I've been fixing up your attempts to display ...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Hi Nick, I think you should post the bitmaps (with explanation) to the end of your existing MM&TT thread for comment. Make it clear that while there is a hint of a curve in the right flags for the font, everything can still be just straight lines when handwritten. If no-one finds any problems, t...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Regarding Fontforge, I am very eager to explore a little, and I have downloaded it... however, I couldn't get it to read the .ttf Sagittal file you sent, even after downloading it to my fonts! Any idea what might be wrong? You don't need to install the font in your system to be able to open it with...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Those are great, Nicholas! Your 6 ppss bitmaps prove that 3 dent and 1 dent can be made sufficiently distinct on a staff space, but they violate a kind of rule (based on my own observation), that I should have spelled out earlier. It's about two black pixels that meet diagonally (only at a corner), ...
