how to set time in trackers and patterns

[rumpelteazer666]

Tracker and pattern objects in blue are great, it was pretty hard to really compose anything in csound before, when you had to manually write the score. But I couldn't find a way to arbitrarily set the time for each note or each beat. The only solution I found so far is to change the number of subdivisions (for the pattern objects), and to rescale the object (for the tracker). For example if it has 64 notes and I set his length to 16sec. (with the rescale property) each note will last 0.25s.

The problem is that this isn't that comfortable, especially if I want to experiment a bit, add, or change something. It would be much easier just to be able to set a new time-for-one-note in the tracker properties.
I suppose there is a way to do this, but I cannot understand how.

I'm a bit puzzled that no one is replying to my question. Since english is not my first language, I fear that I wasn't clear in expressing my problem. Please if my message is not understandable let me know, actually my problem is a very simple one and I can try to explain it in another way. Also, if someone knows that there is no such a feature for arbitrarily setting the speed of a tracker object, is there a way to suggest this to the author? Will he take suggestions for new features? It doesn't seem a difficult thing but I don't know java so I can't really judge.

Hi Rumpel,

Sorry for not replying earlier, things have been busy.  There's no way
to explicitly set the duration of a step or beat in either of the
objects.  One way to work around it is to set the Time Property to
"None" in the soundObject properties, then adding a Multiply Note
processor to work with the p2 and p3 fields to scale the duration and
startTimes to the beat value desired.

The reason for not setting the duration per step/beat is that then
there would be no correlation between the values within the object and
the visual representation on the timeline.  i.e. the length of the
generated score would not be related in any way to the duration of the
object.

The ability to change the value of the beat would have to be
implemented as a new feature.  If you'd like to add a request, please
use the Request for Enhancment in the help menu and add a ticket on
the Sourceforge tracker and I'll try to address.  I'm currently heads
down in the rewrite work for blue2, but I will be reviewing the RFE
and Bug trackers before release and will try to address those that are
quick to implement (which this would be).

Thanks,
steven

Steven, thank you very much. The note processor trick is very useful and provides exactly the control I had in mind. I didn't know about processors until now because I still have not explored all the possibilities of blue. (Suffice to say, I was convinced that trackers were the main tool people used, until I tried to search for discussions about them in order to solve my problem and discovered that they aren't).
I added a feature request anyway, as having such a control in the object properties would be a bit more intuititive for people who still don't know about processors.
