Re: [tuning] Digest Number 1073

Hi Joseph,

Started with the agogo, which I chose as it sounds like it has
good inharmonic partials.

Then transposed it by 1/1 2/1 3/1,... 24/1, and played all the notes
simultaneously.

For the subharmonics: 1/1 1/2 1/3,...

To do it in FTS, I made a custom voice:
Voice | Custom voices | Edit Custom Melod. voices.

Then: Copy custom voice,
Name it as whatever you like,
Remove all except one of its instruments, and copy that
one 24 times.

Then you have to set the Tr. by any interval box to show
the transpositions you want for each instrument,
so you highlight each instrument in turn, and change this
to 1/1 2/1 3/1 etc.

Or it can be faster at that point to save to a .ts file,
then edit the ts file and look for lines like this:

CustomVoice 0
szDescr Agogo harmonics to 10
nInst 24
iInst 0 ipatch 113
iInst 1 ipatch 113 dExtraShift 2/1
iInst 2 ipatch 113 dExtraShift 3/1
iInst 3 ipatch 113 dExtraShift 4/1
iInst 4 ipatch 113 dExtraShift 5/1

To change the transpositions, edit the ratios at the end.

You can use ratio notation, or decimal point (1.25 = 5/4 etc)
or to use cents here, use the notation '100 = 100 cents
(as FTS doesn't parse for the word cents when reading
from the ts file)

If you then want to try it out with another patch, e.g.
melodic tom, do search and replace, and change the
113 to 117 everywhere.

Or for the Glockenspiel, change it to 9, and so on.

I've uploaded a .ts file - same as the midi file with
extension .ts.
http://homepage.ntlworld.com/robertwalker/agogo/agogo_cv.ts
So one can edit that to change the patch to try any same idea
with other voice.

Open the .ts files in FTS, and you can have a go at playing in
the voices from the MIDI keyboard.

You may lose partials in the timbres if you try chords with simultaneous notes,
(
in fact, FTS seems to be responding by leaving out new partials
for the custom voice when notes are still sounding that need the channels - not sure why
- as usually what happens is the new note switches off all the notes in
the oldest updated channel - I'll see what can be done about that.

Also if you hold down a chord with many simultaneous notes, FTS has
so many notes to play, can get interesting delayed play back effect of all
the partials

(with the melodic tom patch,it is rather fun to just hit part of the
keyboard with your fist, sounding many notes at once - gets a nice
dull thuddy sound!)

And of course, such experiments aren't complete without:

Now for the subharmonics!

And here I'm playing around with a melodic tom voice.

I've used the melodic tom subharmonics, and a seed that goes up and down in waves,
changing volume and time in waves as well, plus the time varies with the pitch as well
on top of that.

I made the seed using:
0 to 71 71 to 30 30 to 40 40 to 0 v 0.1 steps 10 to 1 to 0.1 to 1 to 0.1 to 1 to 0.1 to
1 to 0.1 to 1 to 0.1 ; steps 20 1 to 0.1 to 1 to 0.1
(the v and ; steps notation for entering the volume and time is new for next upload of
beta whenever I do that)

(1 min playing time, 217 Kb)

See note at end of previous post too, but I think this explains it
somewhat better,

Those used pure harmonic series for the otonal chords, and somewhat inharmonic timbres.

Would be nice to try the other combinations - inharmonic timbres + inharmonic virtual
partials, and harmonic timbres + inharmonic virtual partials.

Anyone got some good measurements of inharmonic partials I could try?

Or are there some web sites for them (Jacky Ligon - do you have some - could have missed a
post with them)? I suppose they don't need to match the voice - could try a 'cello sound
with
bell partials say, and see what happens!

Will the bell harmonics "otonal" chord sound more harmonious than the "utonal" one in
this case??
