Bob, there must be something fundamentally upside down with how you are trying to get the authorizations done.

First, there is no authorization code for RMIV. Second, Alpha and Cronox codes worked just find for me. Amplitube works fine, as does Sampletank. I don't like the IK registration process period - it's not unique to Tracktion.

To others that bought this program for $19

As for the workflow, to me it's hand-in-glove. I've never accepted that a computer based music software has to follow a hardware layout for signal flow. It doesn't work that way in my brain - even though in 'real life' I do a whole lot of mixing for live sound and deal with the bus limitations that present themselves in hardware mixers.

There are many people that simply do not like Tracktion's workflow. To those that do, it's a boon. Since it's mainly a modular host - one has to think of music production with a signal flow mindset.

However, if all you do is use it to put some shine on a stereo mix - I still challenge any still reading this post to put one of your 'finished' stereo mixdowns into Tracktion, and then apply the Final Mix plugin and audition a bunch of the presets. You are almost sure to find one of the following presets to put the icing on the cake:

Final Mix
CD
(these are the top two presets in the list)

Country with EQ
Rock
Smoothed Out

and a few others I can't think of off the top of my head.

Before anyone chimes in and says something along the lines that this is kind of cheating, that you can do all of this with a series of plugs, here's what you need to be able to combine:

6 band parametric EQ
3 band dynamics processor with settings for crossover points, thresholds, all the other typical ratio, etc.
6 band parametric EQ
Limiter with soft-knee possibilities, etc.

There's nearly an infinite way to combine those 4 different items of signal processing. Use the presets as a guide. I'm almost always adjusting the first 6 band, but I have absolutely no qualms about using the preset as a starting point.
