Ted,
Whilst I fully sympathise with your point of view, may I ask "how would you expect any end user to know about any problems or work-arounds with a product that has just been released? Not just the library of samples, but a new version of ARIA to boot".
The question might well be asked over at the Plogue forum where one might expect David Viens to look into it. I wouldn't have a clue, but count myself amongst the more technically savvy of end users after a long career in the IT industry. (I experiment and modify both the XML and SFZ files.)
Fleer,
The same applies. Why would you expect an end user to know the correct size of the sample libraries download? I have a PC (or two) not a Mac, so wouldn't have any idea. Someone from MM could have answered you, if they could be bothered.

I do try my best to get over here regularly and answer questions as my time allows, but servicing others needs (who not infrequently forget to proffer thanks) is not my priority in life.
Any spare time I have goes into my own MIDI forum.
My own feeling is that if MakeMusic can't even be bothered to respond properly here (I had to cut and paste an answer from another forum) and this IS THEIR FORUM, then I personally don't feel inclined to act as an UNPAID member of their support team.
I'm sure Randy Bowser (from the Northern Sounds forum) who used to answer so many queries and for whom I have nothing but respect, ended up feeling the same. Just my POV.
Nor do I expect a bug in a loop point in a GPO4 instrument, which I reported maybe a year ago, to turn up again in GPO5, not amended. I shan't commit my opinion about that to print.
I do have an embryonic plan to write some articles about GPO5 and ARIA use and how to implement MIDI controls, but I'm holding off until they correct the faults (incorrectly implemented loop points in the sfz code for a few instruments), implement the missing instruments (there's a list at the end of this post), insert ALL the controls into ARIA interface (most, if not all, of the XML has already been written and is there, if you look) e.g. stereo stage and ADSR, and so forth.
It's clear that the release was rushed out to make the February deadline without everything being there.

Perhaps if we had just a modicum more support/participation from MM, I'd feel more inclined to participate too.
Just my tuppence worth, don't be offended please. I just had to get it off my chest!

John.
