rekordbox lighting engineers investigated the User Manual and Database of this fixture and tested the behaviors using rekordbox with a simulator. However, we have not been able to replicate the issue of purple color instead of blue.
To CH:5, all the white:5, red:11, green:32, blue:39, yellow:25, purple:53, cyan(0x00ffff):32 are properly sent.
Please check if "Blue" is enabled at the button shown below.
Thank you for your kind cooperation.
