Replace Stream - Amazing Tool !!!!


Recommended Posts

Dear Friends,

 

Please check this replace-stream function !!

This is what I was searching for and trying to achieve for a long time !!

It really worth to upgrade.

 

I have some questions regarding this new tool:

Here is the code, similar to the documentation.

First, we have the Bach Chorale.

Second, there are some original material that looks like this:

V1 plays only E and F pitch classes

V2 plays only C and D pitch classes

VLA plays only Bb and G# pitch classes

CELLO plays only Bb and Eb pitch classes

 

For easy understanding of the point

When I do the replace-stream, I.E., using the new pitch classes to the old Bach Chorale, I get this

image.png.16f6ad7161c3c1eeadb40047cfd2404e.png

My new notes are traversing the instruments vertically and not horizontally (voice by voice)

I´d like to keep the same pitch classes in each instrument, just with the new rhythms of the Bach Chorale, I.E., the VL1 plays only E and F, the VL2, only C and D, as I had in the original music.

 

It´s just like an inverted axis... (or maybe the distribution is related with the length...)

 

There is some solution ?

I hope so, because this sounds AMAZING !

It´s just what I need !

I was trying to do this with the counterpoint function (in the previous post, with the :harmony keyword, but getting some noise in between, because of the nature of embedded harmonic path inside the Counterpoint function.

 

 

Best !

Julio

Harmonic voice distribution is vertical (stream).

If you wish to apply a series of pitches to voices (instruments) just get count of the lengths form each of the voice and divide the pitch series accordingly - very simple.

If the restream function could collect the notes horizontally from the source score and place the same way in the destination score it would be nice.  

 

Below, I suggest using one restream for each voice. It works like a charm.

 

Another possibility would be having the :harmony keyword in the Counterpoint function working with the exact notes you put, without messing the octaves (side effect of the embedded harmonic path).

 

So the method for composing would be:

 

1) Do whatever patterns you like ( don´t think about the notes, just the rhythmic texture of the Counterpoint)

2) Put the notes you like (in the exact octave you want) in the :harmony keyword

3) Let the counterpoint do the span (according with the longest pattern or specify spans for each measure

4) Be happy !!

 

For my purposes, the counterpoint is still what is "almost there". 

 

Best,

Julio

It´s difficult to keep the right note distribution in the voices and keeping the voicings of the harmony...

I end up having to predefine lengths and making manual calculations making the function superfluous...

 

Nothing to do with calculation or lengths or any of that sort.  🙂

Doing any other way the harmonic work is lost.

 

The voices delta time is of essence.

 

The vertical distribution is very useful in "class composition" (number of scores base on structural template) where your harmonic stream is set and you test it with many possibile scores. Everything in the scores stays as it is: velocity, articulation and duration and only the pitch stream (one by one) will be distributed to all voices.

 

The simplest way to understand the function is to think of music analysis.

Dear Janusz, 

 

Thanks for the explanation.  

I found my way to use it  !!!

Finally !!!

It will be VERY USEFUL (thanks a lot)

 

Here is my way to use it:

In this way, I can just put exactly what I want in each voice.
