the size and position of the accidentals

OpenMusic
#1

Dear friends,

I am curiously that where could I modify the size of the accidentals and the distance between the notehead and the accidental?
I have try to search them in the code of extra-obj but not found. Or is there some global variable to use?

The reason to do that is to use the chord-seq directly for the space notation.
Now the distance between accidentals and noteheads are relatively large, so that it can result in the collisions between the accidentals and the notes before, if the music is very fast and subtil.

Thank you for your help in advance!

Best,
Jialin

Dear all,

Problem solved!
The way to do that is:

make a box named “draw-object”, type “e” and double click the option with “xxxx…grap-note…xxxx”, you are now in the lisp file of this box.

Add a variable alt-pos-offset to the end of 6. line of this function, like this:

                 (round (- (+ realrealpos (* (- (alteration self) 1) (/ size 3))) (* (/ size 4) (delta-head self)) *alt-pos-offset*))

And then set the variable alt-pos-offset outside, like (setf alt-pos-offset -9).

The value from -9 to -6 is quite good.

Best regards,
Jialin

Note that this will not work again at startup if the modified code remains in the sources of the distributed OM version.
In order to get code loaded at startup, copy-paste it in a new .lisp file — don’t forget the (in-package :om) at the top of it — and put this file in your workspace’s “user” folder.

Thank you Jean, for the help and information!
It saves a lot of time and energy. Have a nice day!
