Fixture modes with 'null' channels : bug?

@Millumin

Hello,

In Millumin 5.14.k (macOS, Enttec DMX USB Pro), a 'null' entry in a fixture mode is removed instead of being kept as an empty channel. All following channels are shifted by one address.


How to reproduce (no modified file):

1. Use the OFL fixture "ETC Source Four LED Series 2 Lustr" (downloaded from Millumin's fixture library, identical to the OFL export), mode "RGB": Red Emulated, Green Emulated, Blue Emulated, null, Strobe, Fan Control.

2. Patch it at address 1, set Strobe and Fan Control to non-zero values.

3. Open Window > Monitor > DMX.

Expected (ETC manual, RGB mode: 1 Red, 2 Green, 3 Blue, 4 n/a, 5 Strobe, 6 Fan): 6 channels, Strobe on 5, Fan on 6.

Observed: only 5 channels; Strobe is sent on 4 (the n/a channel) and Fan Control on 5 (the real Strobe channel). On a real fixture, the fan value would trigger the strobe.


How could I keep 'null' as an empty DMX channel (no value sent, address reserved)?

Thanks!
