7Troubleshooting: USB2.0

Computer or audio application does not see the MultiMix USB2.0

Basic troubleshooting

First, check that the MultiMix is seen by the computer: Open the Alesis control panel and check that Windows sees the device as attached.

No connection

If “MultiMix Audio” does not appear, Windows does not see the mixer as being connected to the computer. Check your USB2.0 cable and try powering the mixer off and on again.

As a last resort, re-start your computer.

Audio playback or recording is at the wrong speed

Adjust the buffers in the ASIO control panel or through your WDM application’s audio setup options.

It is impossible to say which buffer settings are perfect for each system, but generally buffer sizes around the middle or low-middle of the available range provide the best results.

When restarting your computer, turn it off all the way. Pull out the AC power cord, keep it out for a few seconds, and then plug it back in again before you restart your computer.

This step helps reset your computer’s motherboard, including any USB2.0 ports and cards.

Audio playback or recording stutters or drops out

Again, work with the buffer settings in the ASIO control panel or through your WDM application’s audio setup options in order to find the most reliable setting.

Many audio applications include advanced setting dialog boxes where pre-fetch and other parameters can be set. Explore those options.

Audio echoes during recording

Either turn your software direct monitoring off or—if you want to monitor your incoming audio through your software—put the MIX TO CTRL RM button in the UP position.

Be sure to attach your monitoring speakers to the CTRL RM OUT jacks, not the MAIN MIX OUT jacks.
