NEUTRON User Manual
11.5 Buzzing or humming sounds can be heard
from the audio outputs.
USB and or audio connections made between different devices using different
power supplies, sources or sockets can sometimes create ground loops. You can
attempt to resolve these grounding issues between computers and the Neutron
by following good grounding practice and ensuring all devices use the same
ground point. Unplugging one cable at time can make the background noises
better or worse, depending on how this affects the remaining ground loops.
By removing every audio cable and working through your studio item by item,
you can potentially eradicate ground-loop problems. Other possible solutions
include the use of a DI box to connect the Neutron to your audio mixer or sound
card where the transformer will isolate the audio connections.
11.6 There is no sound when using the external

audio input.

The Neutron needs the VCA envelope to be triggered and open. This can be
achieved via MIDI or an external E.GATE 1 input, adjust the ADSR settings in order
to hear the input signal.
Another way to use the external audio input is turning up the VCA BIAS in order
to hear audio.
