Con Unable to use Synthesizers / virtual instruments
You can only use effect plugins or record live with this DAW.
Con No native 64-bit version, therefore does not support 64-bit VST plugins
Audacity is available only as a 32-bit application, therefore even when running on 64-bit machines, it only supports 32-bit VST plugins unless they are converted to 32-bit using an application such as JBridge.
