If you are running Reason 12, all rack devices now have hi-resolution panels.
However, if you installed the optional content (Radical Piano, Klang, Pangea and Humana) before you updated to Reason 12, these devices will not have hi-resolution panels until you re-install the devices.
To re-install the optional devices, proceed as follows:
Windows
1. Shut down Reason 12. 2. In Windows Explorer, go to C:\\Users\\[your user name]\\Music\\Propellerhead Content\\Optional Devices and delete the Pangea, Humana, Klang and Radical Piano folders. 3. Launch Reason 12 and select Manage Content from the Window menu. 4. Download Pangea, Humana, Klang and Radical Piano again. 5. Restart Reason 12.
macOS
1. Shut down Reason 12. 2. In Finder, go to your personal library ~/Music/Propellerhead Content/Optional Devices and delete the Pangea, Humana, Klang and Radical Piano folders. 3. Launch Reason 12 and select Manage Content from the Window menu. 4. Download Pangea, Humana, Klang and Radical Piano again. 5. Restart Reason 12.
