Channels sent from the MultiMix to the computer

The USB2.0 port sends every individual mixer channel as well as the MultiMix’s MAIN OUT/2-TRACK OUT left and right signals to the computer. This means that, for the MultiMix 16 USB2.0, 16 individual channels are sent to the computer along with the MAIN stereo pair (18 channels in total.)

Individual channels

The INDIVIDUAL channels sent to the computer send the signal after the preamp gain knob, the high-pass filter, the three-band EQ, and the channel fader.

The effects of the AUX send knobs are NOT included in the outputs of the individual channels.

MAIN MIX channels

The MAIN mix channels sent to the computer exactly mirror the MAIN output of the mixer. If you are only interested in making stereo recordings, consider recording the MAIN channels in your recording software.

Channels returned from the computer to the MultiMix

The USB2.0 port receives a stereo audio stream from the computer and assigns it to the 2-TRACK IN left and right channels of your MultiMix mixer. Note that, if a device is connected to the MultiMix’s 2-TRACK IN inputs, the signal from this device is merged with the signal from the computer.

To understand why the AUX signals are not blended into the individual channel feeds to the computer, consider the nature of AUX sends:

Every channel can send none, some, or all of its signal to the AUX processors. For instance, in the MultiMix 12, 12 different signals could be sent to an external processor, all at different levels.

However, that AUX processor can only return at most a stereo pair into the mixer. There’s no way that the processor could route the effects of each channel back to that channel directly without including the signal from the other channels as well.
