         The rate for this channel switching is around 120 kHz, which means that
         <b>when all 8 channels are enabled, there will be audible channel switching noise at 15 kHz</b>

-        this, but it did little to alleviate the high pitched noise, so it's still very audible.

         To avoid this, either disable multiplexing in the emulation configuration settings, or use a sufficient
         lowpass filter in the emulation configuration settings.</p>
