Yahoo Tuning Groups Ultimate Backup makemicromusic Ideal Tunings for Realtime Key Changes

I've completed completed an instrument 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 MIDI 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?

🔗Carl Lumma <ekin@...>

Great!! What do you call it? Is it a synth? What does it
run on?

Do you support MTS

http://www.midi.org/about-midi/tuning.shtml
http://www.midi.org/about-midi/tuning_extens.shtml

or...?

As for which tunings to include, most folks around here will
want their own custom tunings. The best way to let them have
that is with Scala file support

http://www.xs4all.nl/~huygensf/scala/

AND .tun file support (Rick McGowan or someone -- can you give us
info on that standard?).

As for the general public, 19-tone equal temperament is, in my
opinion, the most important tuning. Early music folks will want
12-tone subsets of 1/4-comma meantone (close to 31-equal) and
1/5- and 1/6-comma well temperaments (like Werckmeister 3 and
Young).

It is a collection of different VSTis for the Wintel platform consisting of
sample players and synthesizers. It will probably run fine on Linux with
Wine, Lampdspa, or equivalent. Apple OS compatibility unknown at this
time. Probably when the Intel chip is in their boxes it will be highly
compatible.

Also the tuning module is to be released as VC++ compiled object code
that can be used with a toolkit such that the user can easily design their
own microtonal VSTi synth for their own use or for commercial sale.

I was on the MMA at one time and voted for the MTS to be approved
many years ago. However, at this time the specification is not fully
implemented in this instrument technology. Perhaps in the future it can
be fully implemented.

> The best way to let them have that is with Scala file support.

The TUN file has an exact section where each of the 128 MIDI notes can
be specified to about a trillionth of a cent. As well the file contains a
fundamental frequency parameter. Scala can easily create TUN files.

To create a TUN file from scala:

Send/File filename.tun

Great, given I was one of the two engineers who put 19TET and other
tuning capabilities into the EMU family of synthesizers, I can easily do
this. Also I'll put the other tunings you request in.

The tuning resolution of this technology is outstanding, it blows away the
status quo. The tuning C++ code is highly portable. I imagine it will
evolve and make it into numerous intstruments.

Jon,

Please see my response in the adjacent post for more details. Multiple
instruments are to use this technology. It will also to be possible to build
your own synth or sample player if this is one of your interests.

Hopefully. Especially the 'single note real time' message in the
tuning extensions.

Yeah, yeah. TUN files aren't human-readable or human-writable,
is my gripe. The instrument should have a front-panel control
for fundamental frequency. It should also be able to handle > 128
notes at a time, and fake this up over MIDI by using multiple
channels, or something.

That was you? I've heard stories that you existed. And I used
the 19-tET feature on a Proteus/2, back in '97.

It's supported by several synths, including VAZ, Rhino, Wusik, Anamark,

Excellent. I've been involved with microtonal VSTis for a couple of years now, helping beat up on likely developers to get them to incorporate the feature. I'm familiar with most of them, and have a good platform for use (and testing). If you ever get to the point of beta testing or you have demos, please let us know.

Very excellent. I'm a tad confused from your postings on tuning: you've got presets that are hard-wired in, but you let users add other tunings as well? I guess I don't understand why you'd want to code in tunings rather than supply the same tunings in a file format that gets read in by default; of course, these are your decisions. But as far as the 100 tunings you use, all I would ask is that the general schools of useage, theory, and cultural practice get as even coverage as possible: include some just tunings, include some ETs, some historic tunings (meantone and otherwise) and a good selection of tunings in use in non-Western cultures around the world. That way a new user would be exposed to theoretic tuning ideas as well as tunings that have sprung from musics past and present.

Looking forward to more on your instruments!

Jon

Jon,

Thanks for the great feedback. One intent of the internal tunings is to
enable users to share patches that have a common baseline. It also is
great for trouble shooting should the user change the directory structure
(i.e. tuning file not found). It is fun for the user to have an instrument that
is flexible instantly without having to do any work to assemble their own
tuning library, especially if they are new to the concept.

The custom tuning file(s) are read when a patch loads. This involves a bit
of computation. Once the patch loads the tuning system takes minimal
CPU while the instrument plays. The internal preset tunings are already
computed, thus instantly available with no CPU hit.

Also, the system has a feature to instantly glide holding notes to the
new tuning when a tuning change occurs. Optionally the user can set
this feature to 'wait until next note', such that holding notes linger at the
pitch of the tuning they were triggered with. The internal tunings broaden
the selection and ability to change intonation in the middle of
performance at a moments whim.

The product is virtually ready to go to market now. With the exception of
completing the internal tunings, an extra feature or two, and some
documentation, the project is complete.

Cheers,
David

All good info.

Aha, smart. How's the CPU usage during actual playing (i.e. the synthesis hit on the CPU, not the tuning)?

Totally sweet! Sounds like this was designed by a musician, for musicians! :)

Interesting! You probably already know that the first Intel Mac
models have been released (iMac, Macbook Pro). I have no idea what
effort it would take to make your applications fully compatible with
Rosetta, but that's what you'll need to do for them to run on Mac OSX:

Paul,

Wow, thanks for your input. Actually I've developed a system of 22
different 22 note shruti. The assorted shruti tunings are ordered (in a
loop) to facilitate smooth modulation from one shruti to the next with at
least a few common modulation intervals between adjacent shruti. Four
of the Shruti systems are brand new unreleased ones I've created. One
of the 22 note shurti is yours (the 7-Limit).

Certainly I can include a 22-tET and rational approximation to 22-tET in
the instrument distribution.

My email is dr_frost_2000@.... Your can email me your phone
or snail mail and I can get you my physical address, however I can not

The "preset" tuning lists are available here:

Carl you got a few honorable mentions in there and thanks to everyone
here that supplied their ideas. It is a great collection with an emphasis
on just intonation.

The omringen website has information for the intonation toolkit and
such, it is just now released. Make your own custom microtonal VSTi

Can't see anything weird. The intervals are given in cents (1/100 semitone), with analysis unit of 1200/192 = 6.25 cents

Re: http://www.omringen.com/tunings.html

These microtuning synthesizers from Omringen are great. But it appears
they only play one note at a time. And what are the comma keys for?

Would it be possible to instantiate a VSTi for each MIDI key you want to
sound simultaneously? After all, justly tempered chords are nice too!
Under some combinations of notes, the otherwise ideal just frequency may
need alteration by one or two commas (21.506 cents, approximately) in
order to preserve the just intervals. This would require communication
among the instruments. Can the host do that, and assign the notes and
frequency correction to an instance of the synth?

Or, perhaps, there is something out there that can already do this....

Thanks in advance for any advice on this.

These are definitely polyphonic - just last night I demo'd the free version of Oblivion, and it is not monophonic. Is it possible you got that impression from the references to "mono"? That refers to the difference between mono and stereo samples.

>Would it be possible to instantiate a VSTi for each MIDI key you want to sound simultaneously? After all, justly tempered chords are nice too!

See above.

And these aren't the first or only microtonal VST instruments available. There are a good and growing number, and some of the others out there are a bit more robust in features and sounds.

Jon,

Actually, I got that impression from the soundexample. An arpeggio is
really a series of notes; I heard no chords in the sample file. Thanks
for clearing that up, though. Perhaps Omringen should claim to be
polyphonic, and to what degree, on the web page. And what DO the comma
keys do?

Is my requirement, to deviate from the tabulated pitch for a certain
note depending on other notes playing, going to be a problem? That part
of the synth seems to be "precompiled" and may not accept more features,
such as this. Is there a list of microtonal polyphonic VSTi products
that I should check out?

These vst's have mac versions:

cameleon 5000, any by linplug, any by virsyn, any by cakewalk, and
any by native instruments

Howard,

The synths are polyphonic. They range from 16 to 64 note polyphony.

Try the synth and you'll see. Internally every component downstream of
the MIDI to CV connection is cloned in the dll, one clone per note of
polyphony. Polyphony can be set as high as 128 when you build your
own synth

The synths can be set to mono mode, then you get one note of
polyphony for performance solos, mono off and synth is polyphonic.

The comma keys are copy protection and unlock features, for registered
users only.

Cheers,
David

The synths haven't yet been tested on a Mac. I've heard there may be a
Win VSTi to Mac software interface now or near in the future. On Linux
the plug in requires software such as Wine (currently untested).

To summarize, WinTel for sure, Linux likely, and Mac now or soon
though not native.

The comma keys are an authorization key, however in the future they
may turn specific features on and off in the code (for example single
note retune).

Oops, I answered the wrong question. Looks like the Oblivion stuff
is pc only. Thanks for the synthedit tuning module.

--- In MakeMicroMusic@yahoogroups.com, Carl Lumma <ekin@...> asked
an searched for something like:

http://www.math.tu-dresden.de/~mutabor/

That's an useful german freeware (Windows) program
for the wanted purpose of real-time key-changes.
The program allows permanently just pure intonation,
my moving stepwise through the Euler-Oettingen
tonal-grid (incl. generalizations into further dimensions),
in actual possible directions of:

3/2(5ths), 5/4(3rds), 7/4(7ths), 11/8(alphorn-fa's)...&ct.

by shifting the functionally tonal-base,
on demand if needed. That happens
whenever an harmonic change occurs
due to an modualtion into one of that directions by occasion.

The online feature consists in:
While playing arbitrary notes on keyboard:
The implemented algorithm produces additional to the usual score
also instantally real-time adaptive retuning into the MIDI-code-stream
depending on the striked keys in order to keep intervals as pure
as possible.
By that, the arising overplus commatic excesses become detected and
immediately decompensated,
--imperceptible done within a few milliseconds--
in order to prevent and escape from any objectionable distuning by
the evil accumulation of commatic deviations,
as inherent in just tuning with a limit number of tone-frequencies.

For instance:
Instead the sharp pythag. 3rd: 81/64 becomes replaced/adjusted and
overwritten/corrected by converting it into just: 5/4, (81/80 SC-down)
before actual sound-output, when detected.
also avoiding 16/9 -->> 7/4 (64/63 septimal-comma down)
and obviate 45/32 -->> 11/8 (33/32 11-limit-comma down)
&ct...by additional specification in the programming-language,
however you want alter or retune intervals on
harmonically conditions.

The goal:
consists in obtaining by that procedure to stay always
within just sounding harmonic overtone-series chords:
4:5:6:7:8:9:11... or even higer limits on demand,
even after modulation into any other key with a new
base-tone, overtaken from a partial of the forerunning chord.
That's achived by inherent automatically comma-shifts up(sharp) and
down(flat)
amounting of: 81/80, 64/63, 33/32.... apt chosen in seize,
so that any below 11-limit interval fits in any case
according the harmonically correct overtone series.
That adaptive property is even kept independent from the actual
choice of the pitch-class-base for all possible modulation-directions,
jumping from chord to chord, while persisting common pitches.

Observed strange behaviour:
The basic reference pitch may roam wandering in comma steps up & down.
That's the inescapable price for just tuning in any
arbitrary key-change on a standard 12-tone keyboard.

Precision: 0.013 cent (1/8192 half-tone)

Try it out and have a lot of fun with that
