VST3 and CLAP on Windows.

No AAX?
Not at the moment. We recommend using Modalics’ amazing (and free!) PluginBuddy wrapper for people using Protools.
Is Sine Machine CPU hungry?
It can be heavy on older machines, especially low notes with unison voices and all the bells and whistles. Otherwise it’s pretty chill.

Yup. 14 day trial. Download it here.
Do you offer offline license authorization?
Not at the moment, you’ll need to be online to authorize the purchase on your computer.
