Controlling Sigma Monitor Controls from an external MIDI device on Windows
In some instances you will want to control Sigma monitor controls from an external MIDI device that does not use the ipMIDI ports. For example, you may wish to map a MIDI keyboard 'Volume' control to the Sigma Level parameter.
On Mac OS this can be achieved using MIDI Patchbay software as stated in the Sigma User Guide.
On Windows 7 we have had success using an application called MIDI-OX to patch an external (hardware) MIDI port to an internal ipMIDI port which can be selected in the Sigma browser. For Windows 8 compatibility it is suggested to use the compatibility setting of XP SP3 during installation.
To set this up:
1 - In Sigma browser designate an unused ipMIDI port as the MIDI LEARN port. In this example we will use ipMIDI Port 5.
2 - Download and install MIDI-OX: http://www.midiox.com/
Note: Commercial use of MIDI-OX after the 30 day free trial period requires a license to be purchased.
3 - In MIDI-OX go to Options>MIDI Devices and select the external/hardware MIDI input port your MIDI device is connected to in the MIDI Inputs list and 05 Ethernet MIDI (ipMIDI port 5) in the MIDI Outputs list. Press OK to close this window.
4 - Test the connection you have just made by opening the MIDI Port Activity Monitor under View > Port Status.... As you move a MIDI control on your hardware device you should see activity on the 05 Ethernety MIDI port.
5 - In the Sigma browser go throug the MIDI Learn procedure as detailed in the User Guide to map the external MIDI control to a monitor control.
Repeat step 5 for mapping additional hardware MIDI controls to Sigma.
