The Novation Twitch is a legacy product, discontinued by it's manufacturer
As such, you may experience issues using it in a configuration that consists of newer releases of Serato DJ Pro, and the latest Microsoft and Apple operating systems.
We have noticed a variety of connection & audio issues in our testing and cannot guarantee operation when the Novation Twitch is used in a Serato DJ release after version 1.9.10 (dependant on OS).
We also cannot guarantee operation when used with operating systems not listed as compatible, by Novation themselves - which are as follows;
- OSX 10.9
- OSX 10.10
- Windows 8.1
- Windows 7
Refer to our Software / Operating System compatibility article for further information about compatible Serato DJ software versions.
