The MOTU audio driver, which enables the computer to route audio to the Ultralite, is setup up differently for Windows machines then the standard audio driver. For this reason, many people have problems hearing audio from their audio programs such as Ableton Live or Cubase. This is because most audio programs send their main left and right output to channels 1 & 2 and often default to this setting. However, the Ultralite does not confrom to these settings.

The solution is to switch the outputs from your audio program to match the output configuration that the Ultralite uses.
These settings can be found on page 40 in the Ultalite User Guide for Windows and below.

The outputs are routed as follows and reflect both the MOTU software control panel and the rear outputs:

Headphones use outputs 1-2
Analog 1-8 are output to ports 3-10
••The Main Outs are ports 11 & 12••
SPDIF uses outputs 13 & 14
