Hey there
Using hog 1000 latest version and all that jazz. And yes I do perform a clean start regularly. The problem happens regularly on different shows.
When I use the default circle effect It does the circle sweet but after a little time running it seems that the pan and tilt get slightly out of phase and instead of a circle you get a diagonal pan ie.top left of proscenenium to bottom right of prosc. I do believe after more time it gets back to circle. Is this something to do with the sine wave/cosine waves being different sizes or speeds or something???
This is using moving heads - Mac 600,500,250+.
Havn't had a chance to have a good fiddle with it. Mite if I get sum time but thought I would see if anyone else had come across this.
Thanks all
Dave Spark
