spat object

I would like to use two spat objects, one rotating clockwise the other counterclockwise.
In the help patch only clockwise is specified. Is there a way to make it move counter clockwise?

List: 4 0 6000 gives 4 revolutions in six seconds clockwise.
What would counter clockwise ask for?

Hi Hans
I don’t have the [spat] object, but here’s how to invert or reverse a line ramp:

Hi Hans,

you could also use the “spat.around”-abstraction, that comes with the IRCAM-Spat ( you’ll find it in the abstraction-folder, and used in the tutorials, e.g. spat.tut.02-2Sources-Octo…). Just give negative Speed ( deg/sec) values…

you could swap the right and left output channel(s) …

Thanks for the posts. I wrote -4 and it worked.
The problem which remained was the use of two spats at the same time. I had a feeling it did not work.
Did somebody try to run two spats at the same time clock and anticlockwise?

Hi Hans,

please see the tutorial I’ve mentioned. You have two sources there. Give negative values to one of them. Open “spat-oper” and see…works like a charm…
