VWinds Contrabass Flute comes with its own sample player, the
UVI Workstation 3 (requires v3.1.6 or later).
We provide it for free with every library that you buy, you don't need to buy an expensive sampler to use our products. It works on Mac (10.14 or later intel or arm processor) and PC (windows 10 or later), in standalone or as a plugin (VST / VST3 / AU / AAX ) and in 64 bits only. You can find more info about it
