x - Troubleshooting

Here are a few tricks that will help you to fix various issues. Please note that at the moment VST plug-ins are loaded into and executed in the application address space, which means a buggy VST plug-in can crash RapidComposer. This area will be improved in the future.



Starting RapidComposer Without Audio

Solution: start RapidComposer with the Alt/Option key held down.

When you start the application, immediately hold down the Alt/Option key and keep it held down until you see a message on the screen.

When to apply: when there are problems with setting up audio. In rare cases RapidComposer sets the wrong audio device by default which causes problems when you try to set another audio device.

[Windows:] When using ASIO drivers, it is possible that there are old, unused, obsolete ASIO drivers installed on your PC. If this happens, you have to manually delete the old entries in the Windows registry.

  • Open the Windows registry (Start → run → regedit)
  • Open the folder HKEY_LOCAL_MACHINE → Software → ASIO
  • Delete the unnecessary audio card entries you do not want or need by right-clicking the entry and choosing delete.



Skipping Loading The Last Composition During Startup

Solution: start RapidComposer with the Ctrl key held down.

When you start the application, immediately hold down the Ctrl key and keep it held down until you see a message on the screen.

When to apply: when RapidComposer crashes during start-up. The crash is caused either by a bug or a badly behaving VST plug-in.



Loading A Composition Without VST Plug-ins

Solution: Alt-click on “Open Composition…” or on recent compositions.

When to apply: when there is an issue during opening a composition file. Typically the problem is a VST plug-in.
