Arturia KeyStep - Controller / Sequencer - Manual (Page 15)

1.3. Rear panel overview
1.3.1. USB/DC IN
This jack provides the power and data connections to a computer. It can also be used with a
standard USB mobile phone charger, allowing you to use KeyStep even without a computer
present.
1.3.2. 9V DC IN (with optional adapter)
KeyStep can be used as a stand-alone device without a computer or tablet present. Simply
connect an optional power adapter to your KeyStep (9V DC, 500ma, positive to ground).

If your mobile device does not supply enough power, you will need to connect a power adapter as
described above (not included).
1.3.3. Pitch/Gate/Mod outputs
These are normally used to send electrical signals to an external device such as Arturia’s
popular analog synthesizers (MiniBrute/SE, MicroBrute/SE, MatrixBrute) or to a modular
analog synthesizer.
The Pitch output is often referred to as Control Voltage or CV. The Gate output is sometimes
known as a Trigger. The Mod output is a second type of Control Voltage output that can be
routed to any number of destinations on the target device.
The MIDI Control Center allows you to configure the type of electrical signals sent by each
output. See section 7.4 [p.41] for information about the signal types that are supported.
1.3.4. Sustain pedal input
Connect a momentary footswitch (optional) to this input. It is best to connect the pedal
before supplying power to the KeyStep so it can sense the pedal’s polarity. Be sure to keep
your foot off the pedal when first making the connection or could work backward. If this
happens, disconnect KeyStep from the power source and start over.
1.3.5. Sync input/output
These jacks allow KeyStep to interface with pre-MIDI technology that was capable of
synchronization, such as early drum machines by Korg and Roland. See section 6.2.1 [p.39]
for information about the types of sync signals KeyStep can send and receive.
