none 2/1 microtunings - scala file import problem

noyzelab	Posted on 03 Jul 2021, 02:59 PM have just been loading in some none 2/1 based tunings and i get a problem of notes resetting to further down the keyboard. an example tuning enclosed from the scala library, reproduced below. as you can see it has 21 notes, with the repeating of the tuning appearing at 4/1. from what i can tell from a brief look, it seems to reset to 2/1 after each set of 21 notes. ! bohlen47.scl ! Heinz Bohlen, mode of 4\47 (1998), www.huygens-fokker.org/bpsite/pythagorean.html 21 ! 102.12766 255.31915 357.44681 459.57447 510.63830 612.76596 714.89362 817.02128 970.21277 1072.34043 1327.65957 1429.78723 1582.97872 1685.10638 1787.23404 1889.36170 1940.42553 2042.55319 2144.68085 2297.87234 4/1 ------ there are a lot of tunings out there that dont use 2/1 as the repeat. see also some the tunings of wendy carlos alpha tuning excerpted from the scala scale library below, this also has the same problem. ! carlos_alpha.scl ! Wendy Carlos' Alpha scale with perfect fifth divided in nine 18 ! 78.00000 156.00000 234.00000 312.00000 390.00000 468.00000 546.00000 624.00000 702.00000 780.00000 858.00000 936.00000 1014.00000 1092.00000 1170.00000 1248.00000 1326.00000 1404.00000 ----- another useful tuning as a check case is the fixed 1/1 tuning. this also loads incorrectly, but in a different way to the others. if you go into advanced mode it is easy to see that instead of computing the same value for all the notes [which should be the master tuning value], it diverges from 0Hz to a frequency value of 42949672.42Hz. this is the scala file to check : ! fixed-1to1.scl ! fixed note tuning of 1/1 across whole keyboard 1 ! 1/1 ---- there is possibly also going to be problems with tunings using repeats at values less than 2/1 if this problem is occurring with the above fixed 1/1 tuning. bohlen47.scl

KODAMO	Posted on 04 Jul 2021, 07:56 PM Only 2/1 scales are supported as indicated here https://kodamo.org/tutorials.php?id=7 May be improved in the future although it is rarely used
DX100	Posted on 05 Jul 2021, 11:53 AM Oh no!😢😱 Some of the most interesting tunings in the universe are not 2/1, I think this now explains the problems I was having with the patch layer transpose now. Basically FULL microtuning is not implemented, damn! Please Kodamo can you implement this otherwise its really half baked and the Essence will not be viewed as an amazing microtuning hardware unit which it is SO close to being.
KODAMO	Posted on 05 Jul 2021, 01:12 PM We'll check how feasible this is. That's only a limitation for Scala file import, you can still do full microtunings by sending a non-realtime MTS message (full dump - 128 notes) to the EssenceFM then saving the tuning.
noyzelab	Posted on 06 Jul 2021, 04:04 AM ok great 👍 thanks for info, will give it a try. it would certainly be handy to have the .scl import work that way as well if possible. i did a batch convert of the scala library to all the output formats including MTS, available here if anyone is wanting to save time https://gitlab.com/noyzelab/scala-scale-lib-bulk-conversion if i'm creating new tunings algorithmically, eg using something like python or mathematica, the scala format is the easiest way to generate & export.
noyzelab	Posted on 08 Jan 2022, 12:15 AM hi is there any chance the Scala import can be fixed to be inline with full MTS please? i have a lot of files that are .scl only and it would be a massive hassle to convert them all. and as mentioned when generating new tunings [and also when sharing tunings], i suspect most people will make an .scl in the first instance anyway. having this sorted out would massively improve my microtuning workflow on this synth. thanks dave
flec8	Posted on 28 Jan 2022, 06:31 PM +1 for this. Would love to have this flexibility. 🙂
Kopplog	Posted on 29 Jan 2022, 12:36 AM +1 to the fullest
Kwerky	Posted on 05 Feb 2022, 03:12 AM Big +1 for full .scl support
DX100	Posted on 12 Mar 2022, 09:53 AM +1 for .scl import being fixed so it mirrors the non-realtime MTS message dump.
