This vst is available free on the site of AAC. This is actually a compilation of various virtual instruments sound banks proposed by the manufacturer.
Although this one is aimed first to discover the sound of these different banks charge, present in the vst Swatches (72 in total, mostly synth sounds, or background) can be used without restrictions.
The sounds are generally very good, of course you have to like electronic music or ambient (found mostly synths, some dancefloor, others more atmospheric).
To the extent that they come from the banks pay, it is not really surprising to be faced with sound quality.
The plugin is well thought out, you can navigate through a menu rather clear and efficient access to different sections (the keyboards are classified by styles), no risk of getting lost.
Finally, this plugin works pretty well since the sound quality has convinced me to invest in paying two plugins ASA (angelical and Film).
But in absolute terms there is already what to do with the instruments present in Swatches.
