pearl2000 patching

[Ernest]

Hi everyone,
i use pearl2000 to control mac2000 and mac600. when i load last show files to console and re-patch fixtures dmx. moving light's pan fine and tilt fine disappear. i check the user setting is 16bit pan/tilt. but if i finish load files and not to re-patch fixtures dmx, moving light's pan fine and tilt fine appear. why? have anyone seem this problem before? thanks!
