Dear Torsten,
Thanks a lot. This music21 is cool, really.
I´m doing the job with this, for a while, since I have to conclude my doctoral dissertation.
Best,

Dear All,
I´m looking for some way of retrieving musical information from sets of notes.
Some problems, for example:
1) This is the first and more needed now:
Given some UNORDERED amount of pitches, how retrive the prime
form and/or Forte Number.
2) How to do this from an existing midi file or XML ? Is t possible to
retrive the forte number of every "n" notes of the pitch collection (melody or chord)?
3) Can you circunscribe some notes for analysis in a large file ?
Thanks, everyone !
Best,
Julio

Very Cool !!! And realistic. Congrats !
-
Yeah, Stephane ! Thanks !
And you changed lenght-div for some-lenght. Great.
I did this today.
By the way, I generated 400 files with this method today !
All the sets mod 12. Like 100 pages, or more.
Thanks !

Hey, Janusz !
It worked !
Thanks for your patience !
This will be an immense time saver to me.
Best !

Hello, Friends !
I'm using the code below to generate combinations of rhythm in 12/8 time signature.
I'd like to have my XML with correct beaming of the notes, related to the most common
interpretation of a 12/8 time signature, i. e., beaming every 3 8th notes.
Instead, I'm getting it more beamed like a 6/4 time signature:
Is there some form of force the right beaming?
All the best !
Please help this doctorate student !

I just read now the first line of your message.
Thanks, Stephane !

Thanks a lot, Stephane ! This is great ! And thank you for
showing me more functions.
However, there some issues: how to control to get a 12/8 instead of a 6/4?
Or: how to get always a time signature with x/8 ? Or always
with a X/4, or mix them ?
In the example you provide, a 12 generates a 6/4 instead of a 12/8.
I changed the code a little:
(setf some-pitches (integer-to-pitch (gen-integer-step 7 480 '(0))))
;>>> here, because I want to stay in the same note g4
(setf lengths (span some-pitches '(q q e q q q e)));>>> here, because I want this specific rhythm, not random sample
(setf some-division '(21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3));here, there's that problem of 6/4 versus 12/8 and one more problem occurred because OM stop changing the timesignature after the number 14 (xml attached) I don't know why.
(setf length-div (gen-divide some-division some-lengths))
(setf time-sig (get-time-signature length-div))
(def-score time

:key-signature 'chromatic
:time-signature time-sig

This is even more simple:
(setf pitches '((g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 HERE COMES THE Pitch List :type :pitch)))
(setf lengths (span pitches '(e -e -e -e HERE COMES THE Rhythm pattern list - same size or less than the pitches)))
(def-score Stage-1
(:key-signature 'chromatic
:time-signature '(4 4) '(1 8) >>>>>>>> Here is the problem: How to span the content through different Time Signatures using the same rhythm list and pitches ?
:tempo 80
:layout (treble-layout 'piano-rh))
(piano-rh
:length lengths
:pitch pitches
:channel 1
:sound 'gm
:program 'clarinet)

Hello, friends !
I'm trying to make some rhythm patterns and I'd like to use the same pattern
changing just the time signature order/or sequence.
For example, assuming an 8th note as the number 1.
2 2 1 2 2 2 1 (african bembé rhythm) as a pattern.
This pattern could match in a 12/8 time signature or also
in a 3/4 time signature. This is ok, no problem.
But what if I like to span it as a 10/8 + 2/8 or 9/8 + 3/8
or 7/8 + 5/8 or in a sequence like 3/8 + 2/8 + 4/8 + 3/8 always
repeating the time signature sequences until have al the notes
spanned ?
Thanks for help !
Best !
Julio
This works for me with ONE time signature only. I need the same
stuff with a SEQUENCE of time signatures.
(setf padrao '((0 1 2 3))) (setf pitches '((g4 g4 g4 g4 HERE COME THE PITCH LIST, padrao :type :pitch))) (setf lengths (span pitches '(e e -e e HERE COMES THE Rhythm pattern list - same size or less than the pitches))) (setf text (span pitches padrao)) (def-score Stage-1 (:key-signature 'chromatic :time-signature '(4 4) :tempo 80 :layout (treble-layout 'piano-rh)) (piano-rh :length lengths :pitch pitches ;text text :channel 1 :sound 'gm :program 'clarinet) )

Thank you, Stephane, for the tip.
Thanks for listening, Janusz (I feel honored) !

I have Opusmodus running on El Capitan.
The latest version is only compatible with Sierra ?
Do I must have to upgrade my OSX to get upgrades ?
Best.

Thanks ! I'll Try !

Dear Friends,
Is there some function that deals with finding the shortest path between,
for example, a trichord "a" to a trichord "b" ?
In general, how to find the shortest path from a collection of notes (i.e. a chord) "a" to a collection
of notes "b" (both in the same cardinality) ?
Thanks in advance !
Best !

Dear Torsten,
Thanks a lot ! Yes, very clear now !
Actually, I have the full software license. I like Opusmodus a lot !

Dear Friends,
Is there some tutorial covering the basic rhythm notation
coding, showing how to write the basic code for
tuplets, beaming, ties, etc ?
For example, here in Lilypond there are a very detailed manual on rhythm coding.
http://lilypond.org/doc/v2.18/Documentation/notation/writing-rhythms
Is there something similar in Opusmodus ?
I´m working in a kind translation of Puredata to Opusmodus, so I need the syntax.
Thanks,
Julio

Thanks a lot, Stephane !
I used Opusmodus to generate a complete catalog of all classes.
I´ll cite Opusmodus in my dissertation, Great tool !
Thank you !
BEst,
Julio
