Yahoo Tuning Groups Ultimate Backup tuning Ideal Tunings That Map to MIDI Range

Hello,

I'd enjoy that some of those tunings were just intonations, since I'm
looking for a software that tunes synthesisers in real time or retunes
MIDI files, in order to produce my compositions in just intonation
without detuning at minor chords and modulations.

Tks,
Cleverson

Assunto: [tuning] Ideal Tunings That Map to MIDI Range

I've completed completed an implementation thats supports custom
intonations as extremely high tuning resolutions. In addition the
implementation supports realtime modulation to other tunings, or by an
interval within the currently active tuning.

Custom intonations can be loaded via file. Given 100 memory locations
for internal tunings (each of 128 notes individually tunable for each
memory location), what tunings are ideal for these preset memory
location?

Having played and performed with Lou Harrison and some other famous
gamlean musicians I will include some of their types of tunings.

What specific tunings do you recommend?

Cleverson,

Lots of the tunings will be Just Intonations. Do you have a favorite?

This instrument goes beyond the status quo Just Intonation type Pure
Major and Pure Minor JI. Also, realtime tuning changes are a breeze in
performance.

Just Intonation 7-Limit, 11-Limit, 13-Limit primes, or JI of non repeating
octaves, rational approximations to a specific well, meantone, or equal
temperment, what are you looking for in the presets?

Cheers,
David

Well, David, I've started to learn and hear examples of just intonation
a few months ago. What I simply want for the moment, although I've been
become each time more interested in non-traditional tunings, is to play
and/or hear my compositions and other pieces played with the same notes
they are in 12-note equal temperament, but in just intonation. Those are
simply pieces in traditional 12-tones scale.

That doesn't really make sense, because one note of 12-EDO can
correspond to many different notes of JI. Sometimes it can be very
difficult, if not impossible, to tell what JI relationships are
implied by 12-EDO harmony.

For example, take the 6/9 chord C-D-E-G-A. It is impossible to tune
this chord so that all the perfect fifths are just 3/2s and the major
third is 5/4. The use of this chord as a consonance assumes that the
syntonic comma (81/80) is tempered out.

Some extremely simple pieces like "Amazing Grace" can be tuned to JI
without any ambiguities or conflicts, but they are the exception, not
the rule.

Gene,

The tunings ideally should cover the basics and inspire people to explore
further on their own. Perhaps a mix of both utility and exotic tunings.

As the tuning presets will be in object code the entire Scala library is far
to vast to include inside of it. However the entire scala library can be
utilized from a TUN file directory. TUN files can be easily be created from
Scala files in several ways.

OK, 19TET, 22TET, 31TET and JI rational approximations of these I can
easily do.

Thanks, Jon.

I tried "sending" a scale (eq 13 3) to "synth 112", and I saw a lot of negative values in the .tun file.

Are the values given in cents relative to MIDI pitch 0 (8.1758Hz), in one section as int, and in another section as double?

If so, I can easily add a ".tun" export to the program I am writting these days ("microabc").

Would you list a few libre software that supports .tun format?

Thanks again,
Hudson

I don't believe (eq 13 3) is a valid command for Scala.

Considering both of these statements, I'd suggest you look into the
info in the following file:

http://www.mark-henning.de/files/tuning.zip

This is the developer of the Anamark synths and creator (I think?) of
the TUN format. In the zip you'll find a complete description of the
file format, as well as source code (which I believe has something to
do with implementation).

> Would you list a few libre software that supports .tun format?

You mean free, no-cost software? I'm not sure that there are any, but
I could be wrong. The instruments I happen to use that utilize the TUN
format (BigTick's Rhino, LinPlug's CronoX3 and Octopus, WusikStation)
are not freeware.

Cheers,
Jon

It is (without the parenthesis). eq 13 3/1 is the ET version of Bohlen-Pierce scale. The generated cents values are correct.

I mean "libre" in the sense of Debian Free Software Guidelines compliance <http://www.debian.org/social_contract.en.html#guidelines>, or software released according to Free Software Foundation definition of free software <http://www.gnu.org/philosophy/free-sw.html> (free as in free speak, not free beer).

Can the softwares you've listed understand the .scl format too?

So far, microabc outputs scala and timidity++ tuning formats (besides microtonal/chromatic/diatonic ABC symbols). Therefore, users of .tun format can do conversion from .scl with scala. I plan upload a new version of microabc this week.

Regards.
Hudson

Well, if those negative numbers are a bug or anamoly, you would need
to ask Manuel, the developer, as to what to do next.

Then I have no recommendations for you.

> Can the softwares you've listed understand the .scl format too?

Some, yes; there are other instruments that I use that utilize the
.scl format instead of .tun, but I didn't list them since you were
asking about .tun. It is a bit of a non-issue (at least for the time
being in my use) since I can convert scale formats with Scala.

I know nothing about microabc (what platform is this for, *nix?), and
as for Timidity, I was under the assumption that this was a program
that had not been developed for a while. It is always frustrating when
a good program stops being supported, but also not a great place to
throw a lot of effort from a 3rd-party standpoint.

Jon

Gene Ward Smith escreveu:

> What is timidity++ tuning format?

The MIDI synthesizer timidity++ <http://timidity.sourceforge.net/> (see also <http://timidity.s11.xrea.com/index.en.html>) can read a file containing a list of 128 frequencies (one per line) to assign to each MIDI pitch. The frequencies are represented in milihertz.

scala outputs such a frequency list when synth is set to 117:

set synth 117
send/file

Given a frequency file named "oldani" (there is no standard file extension; scala uses ".tbl" I don't know why), one can play a MIDI file in this tuning by running timidity in a shell:

timidity -Zoldani file.mid

To get a WAV file:

timidity -Zoldani file.mid -Ow -ofile.wav

and to get an OGG Vorbis file:

timidity -Zoldani file.mid -Ov -ofile.ogg

There are other output modes. I've read that timidity++ for Windows can additionaly output MP3 (strange...).

Hudson

No. The negative values correspond to pitches below 8.1758Hz, when represented in cents relative to this frequency. They are OK.

It is generator of macros for ABC music notation (<http://abcplus.sf.net>, <http://abcnotation.org>).

I put it online just now (66kB):
http://geocities.yahoo.com.br/hfmlacerda/abc/microabc-2006-01-23.zip

The code consists of only one C file. I think you can compile it under whatever system you want.

Here is a description, from "microabc.txt":

<<<<
microabc is a program which generate macros to represent microtonal
music in ABC notation. It is intended for use along the preprocessor
abcpp (for the programs refered to, see links below, at the end of
this file). The post-processed ABC code is suitable for abcm2ps
and/or abcMIDI. Other related tools are scala and timidity++.

The program reads commands and data, and outputs a list of macro
definitions. Macro replacements can be: chromatic, diatonic,
microtonal or literal.

Chromatic and diatonic modes are useful to generate MIDI files to be
re-tuned with the program scala or played by timidity++. They can also
be used to generate a mapping for standard staff notation
(tablature-wise approach).

Microtonal mode computes pitch quantisation relative to the standard
equal temperament (quarter-tones, eighth-tones, etc.), using
microtonal ABC accidentals for abc2midi or abcm2ps.

Literal mode uses given replacement text strings.

There is also a command to write into a file a list of frequencies,
for use by timidity++.

Really, the latest version of timidity++ (2.13.3) was released in October 2004.

I don't know MIDI to use those messages in a MIDI file, as a common MIDI control. Is that really possible? I shall see it.

No. MIDI tuning standard is synthesiser-dependent.

Quoting Seymour Shlien:

<<<<
This refers to a system exclusive command (sysex).
Midifile.c (included with the abcmidi package) has
some support for this command. (I know it can
read or skip over the command.)

As the name implies the command is exclusive to
a particular piece of hardware (eg. Roland synthesizer).
Other synthesizers (eg. TiMidity) may not interpret
these commands.

That example was hypothetical. There is a field to tha synthesiser ID in Standard MIDI Tuning. What should be the value for no a specific one?

Would you send me, please, some small midi files that use Standard MIDI Tuning and the respective scala files, so that I can analyse them and test if any of my MIDI-player softwares supports that?

Please send them to: <<hfmlacerda, at, yahoo, dot, com, dot, br>>.

If you're interested in adaptive JI, where the major and minor chords
are all tuned pure within themselves but the melodic intervals can be
irrational, then you should contact John deLaubenfels:

http://bellsouthpwp.net/j/d/jdelaub/jstudio.htm

If you're interested in strict JI, which uses 'simple' ratios all the
way through, though, you'll have to specify how to deal with various
comma issues, such as those mentioned here:

http://tonalsoft.com/enc/d/drift.aspx

Have you thought through these problems?

Wally,

Hey, great links thank you. The instrument I am about to release can do
the Erlich "shift" or "drift", though not through adaptive JI. The performer
has control of this, decisions about JI key modulation can be made in
realtime with a retention in the purity of the intervals.

Alot of the tunings currently being utilized in this instrument originate
from classic JI, historical tunings, Indonesian Gamelan, Indian shruti,
and assorted size temperments.

It is a performance instrument designed to be easy and flexible to use.
Working great, I'm just putting the finishing touches on the instrument
now.

Cheers,
David

So, here is the long answer I omitted before:

To obtain a tuned MIDI file from ABC notation, one has these options:

1) Generate a MIDI file with pitch bends:

Currently, the abc2midi's support for microtonal notation is
yet basic. In special, chords are output to a same channel,
then this tuned C major chord:

[C_14/100E^2/100G]

will not work. One have to write is as different voices:

C &\
_14/100E &\
^2/100G

2) Generate a MIDI file using a mapping (no pitch bends), and then:

2.1) Re-tune it with scala (or another tool), using pitch bends,
for instance:

scala --eq\ 13\ 3 --example/midi\ map1.mid\ map.mid --exit else:

2.2) Play it with a synthesiser that supports scale definitions
(.scl files) or frequency maps (like .tun format),
in my case, timidity++:

timidity -Zmap map.mid

3) Generate a MIDI file with embedded frequency map, that is to say, using Standard MIDI Tuning.

Given the possibilities above, here is my view:

If I use 1) or 2.1), the MIDI file will be correctly played in virtually any MIDI player or synthesiser, and no additional file is required.

Option 2.2) requires an additional tuning file, and a dedicated player. TiMidity++ is free software, supports soundfonts and can run on several plataforms, hence it's a good choice for file sharing. It seems that .TUN file format is not currently understood by any free software (it's not "so" wide spread, otherwise it would be interest on it), and therefore is not very suitable for file sharing.

Option 3) does without additional tuning file, but I don't know at wich extent it is suppported by hardware and software synthesisers. If it is well supported, I can ask Seymour to implement Standard MIDI Tuning in abc2midi. But I would prefer improve the support for pitch bends first.

Once again, I would like to obtain some MIDI files using Standard MIDI Tuning, so that I can try if any of my (software) synthesisers support it.

But, what is the "easier" option? One can count the number of pieces of software required, the number of files involved, user preferences (for instance, GUI or console software).

But there is more. With Standard (non-extended) MIDI, one is limited to:
- 128 pitches
- 16 channels

Pitch bends affects all notes in a channel, so, one cannot have more that 16 simultaneous notes if each one requires a pitch bend. This can be a problem with certain scales and/or many simultaneous voices.

By the other hand, loading a .scl, .tun or timidity frequency table will normally affect all channels, but only (?) 128 pitches can be used. For example, for a full 48ET scale, less than 3 octaves are available. Beside, one cannot use 2 or more independent scales simultaneously, but only merge them in a map with up to 128 pitches.

One can, of course, combine the two basic approaches: 128 frequencies + pitch bends relative to them. That is a possibility I realized just now. I will think about, it seems very interesting to implement in microabc. So, even .TUN files will can be useful to me, and I can be one of the first free software developers to implement .tun import/export in a free software... 8-)

Regards.
Hudson

Gene,

Many thanks for the MIDI files.

I didn't know that Standard MIDI Tuning works with timidity++.

Here are the results:
- Both pmidi and kmid didn't work here. I think this is due to the soundcard driver, not to the players.
- Timidity++ works fine with SMT.

I will ask Seymour Shlien to enable SysEx messages in abc2midi. For timidity++, really using SMT is easier than using a frequencies table.

Cheers,
Hudson

Gene,

Certainly the instrument works with cents. With my question and revised
rational approximation, one item I was interested in gauging is the
importance of resolution to people. Given the difference in the tuning is
around 1/1000 of a cent in the JI version of the scale, in my view the
resolution is highly treasured in yours and others opinion.

Given much of my work is with gamelan, cents is a highly important
measurement in this instrument. The intervallic relation between
enharmonics, especially for bronze, benifits with an exacting tuning
measurement.

With split fundamentals and a plethora of enharmonics, how does one
represent this with a single JI ratio?

Bouncing ideas off people is creating quite an instrument as I now at this
moment put the finishing touches on the implementation.

Thank you for your input.

Cheers,
David

True, and you forgot to even mention the minor third E-G (6:5) and
major sixth C-A (5/3), additional reasons why you might prefer to
temper out the syntonic comma rather than tune to Pythagorean (a
chain of pure perfect fifths).

Enharmonics are pairs like F#-Gb. Maybe you meant to say *inharmonic*
overtones?

Wally,

Yeah inharmonic overtones as in inharmonicity. Put too many hours in
recently to pass the spelling bee. At least when I say "timbre" people
don't think a tree is about to fall down on their head.

David
