From having spent a lot of time in the Rosegarden source code, it
always struck me that the intent was to optionally have two separate but
simultaneous versions of each note:
1. A quantized version that fell exactly on a beat or sub-beat ("1",
"2-and", "3-and-uh", "4-eee-and-uh", etc) and lasted a standard amount
of time (quarter, eighth, sixteenth, thirty-second, sixty-fourth note,
etc), and ...
2. A real "performance" version that that had "feel", "swing", rushing
or dragging the beat, etc.
This would allow playback of the composition with the desired
performance without having the notation cluttered with
excessive/confusing 128th-note rests, dotted sixty-fourth notes, etc, or
notes in the Matrix Editor that don't start and end exactly on grid lines.
It can be seen in the code in places like Event::setNotationDuration()
and setNotationAbsoluteTime(), and when running official Rosegarden
(it's a little easier in rosegarden-fork) in the Matrix Editor by
double-clicking a note while in "Select and Edit(F2)" mode. The dialog
that pops up has both "Event Properties: Absolute Time" and "Duration"
and also "Notation Properties: Notation Time", and "Notation Duration".
But this feature doesn't seem to have ever been fully implemented.
I see no reason why quantization during recording vs doing it later in
the Notation or Matrix Editors would be any different (and if it used
the same quantization algorithms it wouldn't be) but, yes, when I
started with Rosegarden I spent a lot of time trying to find a "quantize
while recording" button before realizing that the intended workflow is
to do it afterwards while editing the composition.
Unless the button *is* there somewhere and I just never found it. ;)

Quantizing can be used for two main purposes:
1. To make sheet music that looks good.
2. To make your performance sound more "perfect".
Rosegarden is supposed to be able to do either, but I've had trouble
getting it to do #1 without also doing #2.

That might be related to getting sheet music that looks good without
touching the performance.

Thanks Ted,
I will try it next time I am in front of my piano and computer.
I will better understand your comments then.
One comment the person did say was that it was better to use it as you
were playing, vs on recorded items, because the results were better for
some reason.
When reading over what you wrote, it seems as though you quantisize the
recorded notes.
I'll try this and see how things work for me.
I'll bring my comments back and see what you and others say.
Thanks again for holding a beginners hand. I will get better:)

Rosegarden does have quantization. In my experience it works best
from the Matrix (piano roll) editor where you can clearly see the
results.
Select a segment in the main window and press M to launch the matrix
editor. Select some notes (or press Ctrl+A to select all). Now
either press = or click on the "Q" toolbar button. This will launch
the quantize dialog. From here, I would start with the "Grid
quantizer" as that's the only one I've been able to get to work.
Experiment in here and don't be surprised if some of the fields seem
to do nothing. The quantizers are a bit buggy.

Hello
I am trying to learn how to use a track system for making music.
This is
a new experience for me.
In addition to this, I am tryign to write dow my music so that the
music
is not lost from my brain:)
I was in a forum and some one mentioned about using a feature called
quantisation in order to clean up th enotes a bit.
Is this a feature in Rosegarden?
Thanks
Joseph
