What are the minimum requirements
Windows: Windows 8.1 and later

VST3, AU and CLAP on macOS.
VST3 and CLAP on Windows.
Standalone on both.
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.
Do you offer offline license authorization? Not at the moment, you’ll need to be online to authorize the purchase on your computer.
added the ability to map partials to arbitrary frequencies. instead of 500 harmonics, this is 500 sine waves tuned to the same pitch, spread apart a bit, going through various per-harmonic pitch and volume modulation pic.twitter.com/VJSuWnj6bx
