Since these are almost certainly newbie issues, I’ll put them here for a start. If they aren’t completely stupid, they can be sorted into the appropriate categories later. If that‘s OK. :)
1 LS-Core The front screen has a space for the Firmware version which is filled, and a space for the Software version which is not. Seems peculiar.
2 Web Interface On the Palettes Screen in the Parameters Area, when there are more than four parameters to adjust the area is supposed to scroll, but I have not found the way to do it yet. I can adjust the RGB and W, but A and UV are inaccessible to me. So far.
3 Web Interface (Possibly related to 2) The Colour Picker mixes RGB. Luminaire (an awful programme in every other respect, hence my acquisition of LightShark LS-Core) includes W and A (if they are a part of the fixture definition) to augment the final colour. Works a treat!
