Re: [Denemo-devel] A possible scheme script

[rain]

     O.K., to explain a little further, the idea is that someone would use these script shortcuts *AS* they are writing the Cantus in the lower voice (To start; Later, will implement a 'writing Cantus on top, sending auto intervals to lower staff' version). So the approach is an "As you are writing approach", as anything else is too sophisticated for my needs, since one of the main purposes for this is simply as a learning tool, until being able to write the appropriate intervals will become second nature and the crutch will no longer be so necessary. So, now it is working good enough (for my current needs), as long as I am simply writing one note at a time *on the Cantus line*, then the shortcut to make interval appear on staff above, then a new note on the Cantus line, etc.

     Worrying about changing note duration on the staff above the Cantus, I will be able to use my usual keypress-shortcuts for that easily. The script below does work in the manner I described and I've set it up for all other intervals but have just provided an example below (others are the same, just changed the d-AddLowestUp/Down part and number of cursor up/downs for each interval). The only one that gave a problem was the diminished 5th, which needed to be flattened when going down, because the add-diminished-5th down is not in Denemo commands. I will look into adding the part that Richard suggested about dealing with rests later, as that will come in very useful.

     I'll make the menu items, then the palette buttons for shortcuts. Not sure what the best way to make that available when it is ready? Someplace I could upload?

(d-AddLowestUpMinor3)

(d-CursorDown)

(d-CursorDown)

(d-CursorDown)

(d-RemoveNoteFromChord)

(d-SetMark)

(d-Cut)

(d-MoveToStaffUp)

(d-SelectionToEmptyMeasure)

(d-MoveCursorLeft)

(d-MoveCursorLeft)

(d-SetMark)

(d-Copy)

(d-MoveCursorLeft)

(d-AddHighestDownMinor3)

(d-CursorToLowestNote)

(d-CursorUp)

your email will be useful to more than just the recipients (that is

those subscribed to the denemo-devel mailing list) - it will be seen by

people trawling for information about how to do things in Denemo.

I'm not quite sure I understand what you are doing - it can help to add

a few lines of script first to set up the initial condition that your

script is to work with, so for example:

(d-New)

(d-AddAfter)

(d-C)

(d-MoveCursorLeft)

;(exit)

(d-AddLowestUpMajor3)

(d-CursorDown)

(d-CursorDown)

(d-CursorDown)

(d-RemoveNoteFromChord)

;(exit)

(d-SetMark)

(d-Cut)

(d-MoveToStaffUp)

(d-MoveCursorRight)

(d-Paste)

(d-MoveCursorLeft)

(d-SetMark)

(d-Copy)

(d-MoveToStaffDown)

(d-MoveCursorRight)

(d-Paste)

(d-MoveCursorLeft)

(d-AddHighestDownMajor3)

(d-CursorUp)

(d-CursorUp)

(d-CursorUp)

(d-RemoveNoteFromChord)

This starts a new score adds a staff below puts the note C into it,

moves the cursor to that note and then executes your sequence of

operations. The result is that the staff above gets a single-note chord

a major third above the C and so does the lower staff. It will do

something more confusing if you are not on the first note of a measure

(perhaps not applicable if you are adding to a Cantus Firmus with one

note per measure). And as you say it could get upset by the presence of

non-music in the bar (for this problem there is this:

(while (and (not (Music?)) (d-MoveCursorRight)))

which will move the cursor rightwards while it is not on a note or rest

("Music").)

Having said that, I'm not sure what you are trying to do - do you

intend to leave the Cantus Firmus unchanged and put a note or sequence

of notes in the staff above? There's something remotely like that for

entry from MIDI keyboard at Input->MIDI->Chords For Bar and I did

something even more elaborate myself https://vimeo.com/62426412 which

shows a script letting you add chords to a bass line (the script is in

Educational->MIDI->Handel's... I think).

It will be great if you can add to the facilities for aiding composers

using Denemo - most work has been done for transcribing. And, indeed,

most composers still use paper and pencil and only turn to a computer

to transcribe their work.
