Neural Mix Pro for Mac is available as a free download through the Mac App Store. The free app allows you to create beat-precise loops, change tempo, and transpose the key of a song, all while separating vocals and instrumentals of songs in real-time.
To gain access to all advanced features of the app, including offline export, you have the option to upgrade via in-app purchase.
Please note that Neural Mix Pro requires macOS 10.14 Mojave or newer.
