Difficult one this, If you've worn out Lj I'm going to struggle to recommend anything that's as good. What level are you at as an LD Stiffler? The reason I ask is I'm a listed instructor /trainer and have been involved with Martin since the old 3032 pc control (pre dmx).
Advanced use with Lj opens it up more, understanding all the patches you can apply certainly makes control easier.
Lj manager with led trix -perfect for pixel mapping.
Lj touch with a touchscreen is still one of the fastest methods of running a 'dance show' and is ridiculously easy to run with Beyond and an apc 40.
Single Usb (1 universe 512 channels) are crap and a waste of space as you have no dmx in which is essential to try and get round the laughable midi mapping.
There is a working beta of a 'new' version but Harmony (who have bought Martin) are insisting it can only support 'one key' which is causing problems as we all know with the Usb universes they are no where near as reliable as the pci /pcmcia universes. I use a 14 year old dingle and you know how many failures I've had in 14 years.
None!
