Yes, there's a @voicespacing attribute, but you may also shift+click on the clef & drag.
Also, see #spacing and #vzoom in the help center.

That's fantastic, thanks so much!

I understand. Thanks for the clarification. No, dada.cartesian won't allow for you to draw on it. Dada.cartesian is a window on a dataset, not a drawing tool. Another option is still LCD inside a bpatcher to scroll. Otherwise, your best bet is custom coded canvas (either in js or c), which if course...

Hello Luis, I'm not sure I've understood completely what you look for. As far as I remember, UPIC notation is more image-like (so lcd or jitter?). If you want to scroll horizontally, bach.roll is the first option. You can use pseudo-graphic notation in bach.roll if you hide the staff, clef, accident...

Not natively in bach.circle, but... a transparent [lcd] object superimposed over it?

Setclock is definitely a solution if you want to control the speed.
If you want something fixed, have a look at cage.timestretch
Or, you can send messages to bach.roll such as: "sel all, onset = onset / 2, duration = duration / 2"

Best,
Daniele

Hello, I understand. So far, gluechord, though, doesn't "fix" gaps. But it should, I agree. I think the code doesn't account for the possibility that gluing happens both at left and at right. Also, the other quirk with the single note to the left is weird. I'll look into it. Thanks for reporting in ...

Glad to hear it. With overdrive off, not even [metro] is reliable in Max

Hello, if memory doesn't trick me (I am away from the computer), energy is the average velocity, weighted by note duration. So, yes, silences will lower the total. Spread should be either the variance or the standard deviation of pitches, perhaps also weighted by velocity/duration. I don't remember ...

Are you sure you have Overdrive on in Max?
