  • opmo changed the title to Session 9 - 11.07.20

Thank you very much, dear Stéphane, for this very interesting session.

I have a question: There are programs, which I can evaluate or put to the MusicXML Viewer and to the audition via Command-1 as snippets. And there are other programs, where this doesn't work and I have to go over Tools: Evaluate Score: Audition and Notation to see and hear the score. Why this difference?

When the MusicXML Viewer and Audition was generated via Snippet, then I have no problem to export the xml via File: Export: Last Score to MusicXML …

But when the MusicXML Viewer and Audition was generated via Tools: Evaluate Score: Audition and Notation, then I can not export the xml, because in File: Export: «Last Score to MusicXML …» is grey. How can I then export the xml?

Click inside the displayed score To give it the focus and press cmd+s to save it as music xml.

About the difference, some scores use ps function and some others use def-score, so the approach is a bit different for evaluation.

I clicked in the MusicXML Viewer to activate this window and pressed cmd+s to save it, but I only hear the "error-sound" of the computer. (Under File: "Save" and also "Save as …" are grey.)

Thanks a lot, Stephane !

Great meeting !

 

I have one question, regarding the use of customized methods.

We can put on def-library folders in the Def-Unfold_Sets

a file with our customized methods.

This file must have an specific name ?

The sets of  methods are automatically loaded in the startup , so we can call the specific sets in

the unfold function without having to evaluate the complete procedure of each method ?

 

I did an 11000 lines of code with my book´s chord library. Took me 2 weeks in notepad++

It takes like 7 minutes to load, but its a kind of shortbreak to common practice chords. 

Now with MIDI entry, things can be easier for common practice guys like me, who dont want to

 have chords generated by vectors, but by specific tonal or modal chords.

But I had to copy octave up and down versions of each chord and it multiplied the line numbers.

With a preloaded method of transpositions this could be easier, maybe...

 

All the best !  Thanks again !

Best !

Thank you, Stephane and Janusz !

 

Maybe I will need some help of you.

 

The library looks like this. THis is one of the 4-note chords:

It allow me to call chords using chord symbols.

Best,

Julio

If this library is quite big would be better to do that with table and not with functions - just with results (values).

The values (chords) are fixed therefore:

(setf c7mt7 '(c4 e4 g4 b4))
(setf c7mt5 '(b3 c4 e4 g4))
(setf c7mt3 '(g3 b3 c4 e4))
(setf c7mt1 '(e3 g3 b3 c4))
(setf db7mt7 '(cs4 f4 gs4 c5))
(setf db7mt5 '(c4 cs4 f4 gs4))
(setf db7mt3 '(gs3 c4 cs4 f4))
(setf db7mt1 '(f3 gs3 c4 cs4))
or
(setf c7mt7 'c4e4g4b4)
(setf c7mt5 'b3c4e4g4)
(setf c7mt3 'g3b3c4e4)
(setf c7mt1 'e3g3b3c4)
(setf db7mt7 'cs4f4gs4c5)
(setf db7mt5 'c4cs4f4gs4)
(setf db7mt3 'gs3c4cs4f4)
(setf db7mt1 'f3gs3c4cs4)

Yes, Janusz !

Great !

Thank you.

But I already did it.

Maybe a second version, without functions would load faster. But actually I dont mind to wait 5 or 7 minutes for loading because it saves me a lot of typping after. I just have to choose my chords intuitively in guitar or piano and after I use chords symbols and manipulate the inversions.

 

Thanks a lot !

Best,

Julio

Dear Janusz,

 

I think that this could be a good thing to really implement in Opusmodus. I´m  finetuning it, because it involves not only a programming point of view, but also a theoretical and compositional way of thinking music. I feel that it deserves a better explanation, because a lot of chord symbols are based on my experience and also based in my Combinatorial Harmony Book.

 

After the finetuning, I´m going to make an video explanation of it, to make the things clearer. 

If you are interested we can build something to include in the current library of Opusmodus. 

 

All the best !

Julio
