MIDI Ports
CHANNeLS 1-8 Select the MIDI Port number corresponding to the master section and channels 1-8 of the MCU/EuCon
controller layer designated for Sigma communication.
CHANNeLS 9-16 Select the MIDI Port number corresponding to channels 9-16 of the MCU/EuCon controller layer
designated for Sigma communication.
In Delta (MCU) Protocol, these are matched to your control surface MIDI ports. In Pro Tools, Cubase, Nuendo and
Ableton protocols, these are matched to the HUI/MCU units assigned in your DAW.
Note. If you connect another MIDI device to your setup during Sigma operation, restarting the Sigma Remote app will
affect the chronology of your MIDI port settings for controlling Sigma. On restart of the Sigma Remote App, reassign
the MIDI ports to there original settings.
MIDI Absolute
offers an alternative way of controlling Sigma's analogue gains directly from the DAW. Instead of using the δelta-control
The MIDI Absolute box will become available if MIDI is selected in the DAw/PrOTOCOL drop-down list. MIDI Absolute
plugin or receiving volume messages over the HUI/MCU protocol, MIDI Absolute works by receiving MIDI volume messages
directly from the outputs of MIDI tracks within the DAW. Set the MIDI Absolute ipMIDI port to be the same as the ipMIDI
port that your 16 MIDI Track outputs are set to in the DAW.
Note the Channels 1-8 and Channels 9-16 drop-down boxes have no effect when MIDI is being used.
MIDI Learn
Many functions on the MASTer page of Sigma can be enabled/disabled from an external MIDI controller sending CC
messages (e.g. the CC layer available on an SSL Nucleus). You should set this drop-down to match the ipMIDI port number
from which the MIDI CC messages are being sent on. For instance, if Nucleus' CC layer is setup on DAW Layer 3, this drop-
down should be set to ipMIDI Port 5.
