ARTURIA – BeatStep Pro – USER’S MANUAL 53
9 CV/GATE FUNCTIONS
BeatStep Pro provides direct access to some of the best music technology the world has
produced in the last six decades: USB, MIDI, Clock and CV/Gate connectors are all
present on its rear panel in a space not much larger than a pencil.
Connection diagrams for each of these interfaces are available in section 2.1 .
In this chapter we’ll focus on the features of the BeatStep Pro CV/Gate circuitry. See
chapter
12 for in-depth coverage of the MIDI features available to you with the MIDI
Control Center.
9.1 SEQ1/SEQ2: Pitch, Velo and Gate
9.1.1 How do they work?
When SEQ1 or SEQ2 is selected the notes you play on the pads are translated
immediately into Control Voltage (CV) and Gate signals and sent to the connectors on
the back panel. Three independent voltages are sent for each note: Pitch, Velocity, and
Gate open/close.
The sequencers can record what you play on the pads, and then you can use the
encoders to change the pitch, velocity and gate time (duration) of each note. When
sequences play back they send those signals to the attached devices through the
CV/Gate connectors, just like the pads would.
However, the pads can’t “play” the CV/Gate connectors while the unit is in Control Mode.
You can start the sequencers, though, and they will play the attached devices while you
control your DAW and play your MIDI devices from Control Mode.
9.1.2 Can my DAW send CV/Gate signals?
It’s possible to send note data from a couple of MIDI tracks on your DAW to the
BeatStep Pro CV/Gate jacks. When the MIDI channels match, that’s what will happen.
There are two things to keep in mind, though:
•
All CV/Gate jacks are monophonic, so if the selected MIDI track on the DAW
contains polyphonic data, playback could be extremely unpredictable. It’s best to
send only one note at a time to the CV/Gate jacks.
•
CV/Gate jacks can send only basic signals: pitch, velocity and note on/off. In
other words, the BeatStep Pro encoders aren’t able to control synthesizer
parameters through the CV/Gate jacks, for example. All edits to your modular
synth settings need to be made on the synth itself.
9.1.3 How should I route the signals?
Typically the Pitch (CV) output is connected to a Voltage Controlled Oscillator (VCO), the
Gate output is connected to a trigger input or a Voltage Controlled Amplifier (VCA), and
the Velo output is connected to a VCA or a Voltage Controlled Filter (VCF) or both
