it would be a great feature when playing back a cue that has an effect to be able to alter the pan tilt directly during the show instead of using the editor as currently if you select the fixtures and adjust the value the effect stops and there is just an output for the pan and tilt value.
Amir is correct. Once the effect is in the programmer, you can easily adjust the base value. You can use suck or touch to grab the effect from on-stage. You can hold the Touch key and then touch either the pan and tilt encoders or the Position hard key to grab just the position and effect data.
