***Please note: If you don’t use ReWire at all, you may do one of the following...
a) Disable the ReWire service in theStudio One preferences under Studio One>Options (Preferences on Mac)>Advanced>Services
b) Delete the files
/Library/Application Support/Propellerhead Software/ReWire/ReWire.bundle
When starting Studio One 5, if you see a ReWire error message, please install the latest version of ReWire. To do this, follow the steps below...
1. Close Studio One.
2. You will need to install an application that installs the latest ReWire library. We might suggest the Ableton Live Demo from Ableton's web site.
***The reason ReWire is not installed with Studio One 5 is because Reason Studio is retiring ReWire in 2020. This is stated on the Reason Studio Developer page: https://developer.
