Not perfect. But a lifesaver when you need it.

These profiles won't always be flawless — a channel set can land wrong, an attribute can need a nudge. But when the fixture is in the rig, doors are in twenty minutes and the manufacturer has never published a GDTF, this gets you patched and programming instead of building a profile by hand. Check your attributes and verify anything critical before the show — you can review and edit the output on GDTF Share.
