Seems almost typical Mackie
I'm sure the PreSonus StudioLive wasn't developed with live sound guy input either - it took a couple updates before it didn't suck too. I wish PreSonus would make a rackmount surfaceless SL that was controllable via an iPad without needing a Mac in between. That would blow away the DL1608 for sure!
OTOH the rumor is that Mackie is releasing a new firmware at NAMM so if they at least fix the aux tap points most of us will find it usable. Personally I want the tap points to be selectable per-channel - for instance I usually need compression on the keys and EQ on the kick in the monitors. Oh, and I need the send for the 'verb on horns to be pre-fader if the horns are plenty loud to carry the room but I want 'verb on them in the monitors and maybe some 'verb in the mains to sweeten them.
