OM questions

shingkweitzeng · September 18, 2015, 4:24pm

Hello!
several questions:

I created a OMWorkspace in the Home directory, but in the real OpenMusic OMWorkspace is a different one, I might astray, how can I find the real OMWorkspace? (ref. shortcuts)
How to import materials (sound files)in the In-file of OMWorkspace?
3.AS->OM (Repmus)can be replaced by sdif->chord-seq?
4.If Chord-seq in a quarter tone how about save-in-mid, midi file semi tone only?
5.In my patch, sdif imports a chord A and gets a result of midi file A (evaluate to the bottom), then I import a chord B to sdif and evaluate to the bottom, but remain the same chord A (can’t be changed), how can I multiple use the same patch?
thanks for your help.

best

1. I created a OMWorkspace in the Home directory, but in the real OpenMusic OMWorkspace is a different one, I might astray, how can I find the real OMWorkspace? (ref. shortcuts)

=> The contents of what you see in the OM workspace windo is in the “elements” directory of the “real” folder

[see http://support.ircam.fr/docs/om/om6-manual/co/Workspace(s).html ]

2. How to import materials (sound files)in the In-file of OMWorkspace?

=> Just copy the files in this folder.
Note that this is just a utility to use the “infile” box in OM patches,
imported sound files can actually be anywhere on your computer.

3.AS->OM (Repmus)can be replaced by sdif->chord-seq?

=> Yes, but the result will be slightly different.

sdif->chord-seq is a raw conversion of the SDIF data, while AS->OM peforms some processing, such as filtering, grouping chords etc. which can make the result more “musical”.

4.If Chord-seq in a quarter tone how about save-in-mid, midi file semi tone only?

=> The MIDI format does not support 1/4 tones

Hello Jean,
Merci beaucoup de réponse chaque question de moi, c’est très gentil!
Here are two results( .musx for Finale) of my research, the Japanese Gagaku music I am satisfied, but the Buddhism lesson_2 is horrible.
The music if you will please download from Soundcloud :
https://soundcloud.com/shing-kwei-tzeng/gagaku-1

I will try with AS (Repmur) next time, if can improve the Chord-squ, as you indicate.
The midi format doesn’t support 1/4 tone, hand copy might be the only way to write the result of Chord-squ? ( for a 30" music I have to enlarge to zoom 400, otherwise it’s too dense to read.)

I will follow the Forum ruler next time one topic only one question.

thank you again.

After read Website and Documentations of Infile, Outfile honest to say I still in puzzle. In my concept Infile is for Import any file, outfile for exporting, it seem total wrong.
Saying if I have over 100 sdif files (e.g. 30"~50")want to transfer to chord-seq, can I put all in a Infile in order to avoid back and forth from a outside follder?

thanks Jean

Yes you can put it anywhere you like.

in/out are just the names of two “defaul” folders. Actually they can even be the same folder if you want.
or you can not use them at all and use your own folder names and conventions

Hello Jean,
I use sdif Tutoria 04-get-object analyze a short gagaku music (ca. 11") and enlarge the Chord-seq to maximum (zoom 1000). then export to two types

OM instance: it is empty and can’t re-open.
to bach:it is in text format.
How can I transfer a sdif->chord-seq to a music notation? please step by step, it is really very difficult to me.
thanks
ref. attachment please.

Hello Shing-kwei

It depends where you want to export your chord-seq to ?

OM instance is an internal format that you can use to re-import in OM only (open an other empty chord-seq and “Import”)
“to bach” is used to export to bach (in Max) http://www.bachproject.net/

If you want to go to Finale, Sibelius or other notation software you need to convert to a VOICE object (real “musical” notation) and then export it as MusicXML.

Hello Jean,
since chord-seq can only “save as” or “export” to midi file ( it is useless for notation; even 4 staves 4 clefs XML of Voice GGFF, import to Finale will be only 1 staff 1 clef), I have to copy the analyses of chord-seq manually ( handwriting), it costs enormous screen (monitor), i have to enlarge zoom to 500, font size 48, do you have another solution? furthermore, if an accidental indicate the same 2 notes, how about the next one? remain in nature? ( because sometimes there are 2 the same accidentals before 2 the same notes. ref. attachments please)
thanks

Hi,

There are more than one time the same note probably because they’re note the same pitch, but approximated to quarter tones in the display they become the same note. You should try using first an approx-m (set to quarter tones) object on your pitches, followed by a remove-dup. If you’re using sibelius for example, you can import the chord in XML and then use the explode function to parse it on different staves.

I guess one accidental mean one of the two notes is concerned, two means two of them and so one…

Dunno if that can help you, I’m not an advanced user.

Best !

shingkweitzeng · April 25, 2016, 9:22pm

hello Paddys, thanks your feedback.
I suppose one accidental just to function one and the other one should be nature, ( ref. attachment accidental); two accidentals before two the same notes then act both the two notes.( ref. attachment accidental-1)
I don’t use Sibelius, but chord-seq can only save as or export to midi ( even via bah.llll), no way to transfer to XML right?

paddys · April 25, 2016, 9:46pm

As far as i know you can’t export xml’s from a chord-seq. Just plug your chord-seq into a voice (and adjust the rhythm quantification settings in the preferences if needed) and then use export-musicxml (don’t forget to add the optional inputs with > and set the approx to quarter-tones).

Hope this can help !

jeanmicheldarre · April 25, 2016, 10:54pm

Of course like Paddys said you have to connect your chord-seq to a voice then to “export-musicxml” function.
You have to adjust tempo and quantization in the preferences menu and you are done.
“export-musicxml” even allows microtones as you can see on the picture below.

My two cents.

shingkweitzeng · April 30, 2016, 4:41am

Hello! Jean Michel, Paddys,
thank you very much, it’s almost done.

the first problem import XML to Finale only 1 Staff. I might learn Sibelius or ask the developer of Finale.
density too hight, I will try use AudioSculpt to reduce chord-seq fewer harmony, less transients ( markers?)
thanks again the patch of Jean Michel is very practical, useful for me.
