Error 22 indicates a communications error between Kyma and the Kyma FireWire Interface. This is usually rare, so if you are getting this error message often, please contact Symbolic Sound. (Often this will happen when another FireWire device is connected or disconnected from your computer.)
Usually, you can recover from the error by choosing Initialize DSP from the DSP menu. However, this error may indicate that the Kyma FireWire Interface has crashed. If this has happened, quit Kyma, remove the power from the Kyma FireWire Interface for a few seconds, turn on the power to the Interface, and restart Kyma.
