These tests are designed to illustrate the performance you can expect from your MusicXPC computer with the above software/hardware application.

In these particular tests, we used 32 audio tracks at 24-bit/96kHz resolution and measured CPU performance/overhead. We also ran tests using the Waves Renaissance and TrueVerb reverb plug-ins, some of the most CPU intensive we can find. The results show the maximum number of reverbs that can be loaded concurrently before the system 'red lines' into CPU overload.
