Intuitive, comprehensive, versatile…as of December 2013

Not my first DAW. I use it for re-mastering, creating component parts for use in other applications, Dub editing, etc. Spendid product and very competitive vis-à-vis price.
HOWEVER, the last update ( January 2014) is not working correctly…and here is how…
When using Effects, such as AU or VST - but not limited to these - one can select a Preview option to hear the effect of changes one makes in real time, BUT only once or twice before the Preview button ceases to work. One must then Quit the application without making any changes on any of the various controls for that particular Effect, such as an AU-EQ slider. This will mean that the relative position of the various adjustments and values will not change upon Quiting the application, nor will any change take place in the document that was open since the last time one has selected Save or Save As. Re-opening any document and returning to the last used Effect will display the Effect is the same state as when one previously Quit the application, and now will give you one or two fresh uses of the Preview button.
For me, this means Double-Clicking on the Amadeus document to re-open the file and application in one step - then continueing on with what I was doing a moment before.
As a result of the above mentioned update, when I Double-Click on that last document a Dialog window now opens to inform me that Amadeus Pro is damaged in some way and it must be re-downloaded from the App Store. This is a hassle and does not solve the problem. Ignoring the Dialog window and dragging the file to the Amadeus Icon in the Dock opens the file and I continue forward…. BUT, I now have to insert several steps into the re-opening process which diminishes through-put, concentration upon the task at hand, and efficiency….
More later when this gets fixed…IF EVER!
