Keith McMillen Instruments QuNexus Reference Manual

2.2.2.1 The KMI MIDI Expander
Dimensions: 4” x 1.25” x 1.25” (inches).
Weight: 2.5 oz.
The KMI MIDI Expander is an optional
accessory, which enables use of QuNexus with
hardware MIDI devices. Plug the receiving MIDI
device into the MIDI Out port and QuNexus will
send MIDI data through a regular 5-pin MIDI
cable.
To use QuNexus with the KMI MIDI Expander follow these steps:
1. Connect a QuNexus to the KMI MIDI Expander (see Connecting QuNexus for
instructions).
2. Plug MIDI devices into the MIDI Expander using 5-pin MIDI cables. The QuNexus will
now send and receive MIDI messages through the MIDI Expander.
2.2.3 CV
QuNexus can communicate with synthesizers or other CV devices using Control Voltages.
Connect QuNexus to CV devices using a cable that is compatible with your CV device’s CV
ports. Using adapters if needed, make sure one end can plug into one of the stereo 1/8in CV out
ports on the left side of QuNexus. QuNexus’ CV input port (on the right side) requires one end to
be a 3.5 mm TRRS (like the ones used for Apple iPhone headsets).
Warning: QuNexus' CV In is uni-polar. If you send it a bi-polar signal, half of the signal will
be clipped and can cause malfunctions in extreme cases. Sending a signal above 5 Volts is
also unsupported. See the Converting CV Input from +/- 10V to 0V/5V chapter for information
on how to make a converter.
The following section provides more detail about the cable connectors needed for QuNexus CV.
