Reason 9.5 has been in beta testing for about a month before release. During that time, we’ve made sure the app itself runs stable and we’ve tested it with more than 7000 VST (2.4, 64-bit) plugins. We’re happy to say that Reason works really well with the vast majority of them. For some plugins, there is still work to be done in Reason and we are keeping a close watch on which ones Reason has troubles with and what we can do to fix the situation.
If you experience crashes or severe performance issues in Reason when working with VST plugins, please get in touch and include as much information as possible, such as which plugins, what situation, your computer specs and preferences. Please, use the regular Support contact form for these reports.
Here are some things to try if you are experiencing problems:
- If you’re using a Mac with a retina display, make sure you start Reason in Low-resolution mode. You can set this by right-clicking the application and choosing Get Info.
- If you’re using a Mac with a dedicated graphics card, turn off “Automatic graphics switching” in the Energy Saver preferences.
- Make sure your audio interface drivers are the latest version and use native ASIO or Core Audio drivers.
- We recommend a buffer size around 512 and a sample rate of 44.1kHz.
- If you’re experiencing crashes or issues with specific plug-ins, try disabling them in the Manage Plugins window.
- Make sure “Use multi-core audio rendering” is enabled on the General tab in Preferences.
- If you’ve used the Reason 9.5 beta version, make sure you’re running the release version and not the beta (which has logging code and runs slower)
