Hi there,

 

I have two questions:

1) Does somebody know, if there exists a function, that connects the common notes of two chords? For me, the function "filter-tie" only works with individual voices, but not with chords.

2) I didn't find the organ in the GM Instrument Set.lisp Did anyone else wrote a piece for organ?

 

Thank you and best wishes,

René

Dear René,

 

Maybe something like this.

This works for de-mixing a texture onto 4 voices, each with differen rhythms.

Hope it can help.

Best,

Julio

Dear Julio

 

Thank you very much. I also worked with pitch-demix. With pitch-demix I've got single voices. With single voices filter-tie works, but not with chords (e.g. two chords for piano with common tones).

 

Best,

René
