Beware! Like many VST's Free Alpha is provided to be installed as 32-bit but also to be installed as 64-bit (in the case of FreeAlpha you must launch the same installer twice and make your choice each time).
32-bit VSTs must be used only with 32-bit DAWs.
64-bit VSTs must be used only with 64-bit SAWs.
So... always the same recurrent question which in 95% of the cases resolve the problem: are you sure that you try to use FreeAlpha 32-bit (named "freealpha.dll") with Ableton Live Lite 32-bit and that you try to use FreeAlpha 64-bit (named "freealpha 64.dll") with Ableton Live Lite 64-bit?
blackwinny, thanks very much for the reply. (I use Ableton Live 9 Suite, 32-bit, by the way.) I read the 'Read Me' system requirements for Alpha too quickly, misreading that ProTools was required for it to work. .. my bad - it works just fine. i'm trying out the free version as I'm keen to use its microtuning capabilities.
