Disappointed to hear that the Solution will no longer get software updates, but I can understand why, given the age of the product.
Will the final version of software for the Solution enable any extra features, like you are on the FLX desks? Maybe more universes (over ethernet), more fixtures, use of faders 1-48 for fixtures, etc?
On another subject, how about making PhantomZerOS be able to output, say 1 universe, to a cheap DMX dongle like the Chamsys MagicQ software does? Chamsys are clearly using this to try and introduce people to their products so they will then be more likely to buy the hardware, so maybe Varilite also should.
