Channel Controls; Cv Outputs - Arturia KORG MS-20 V User Manual

Gate: sets the Gate length for each step. Think of the Gate length as a sort of
•
'pulse width' – if each step is a cycle of a pulse wave, then the Gate length sets
how much of that step length will have the note turned on. A short Gate length
will make each note very short and clipped, while a long Gate length means
that each note will last almost as long as the Step is. Gate length is expressed
in percentage of the Step length. The knob has a range of 5.00% to 95.0%, and
double-clicking it will set it to 50%.
Portamento can be set separately for Channel A/B and Channel C. Thanks to the
•
strong influence of sequencers like that in the famous Roland TB-303, musicians
have come to enjoy the ability to slide between the pitches of steps rather than
simply jumping from one to the next. This helps sequences feel more expressive
and less robotic, and is a common feature in many genres of electronic dance
music. The Portamento time can be set from 0.010 seconds to 2.82 seconds.
Portamento is only added to those steps where the Portamento switch has been
pressed.

6.1.2. Channel Controls

The sequencer is designed to work like a conventional analog sequencer from the days of
modular synthesizers. Each Step has a CV Mapping knob to set the CV being output, in terms
of an offset from the base voltage (usually determined by the key being pressed).
While the CV Mapping knobs are labeled from -5 to +5, with 0 being the default value that's
set when you double-click a knob, the actual value being output depends on the Channel
Range switches for each channel, allowing for finer or coarser CV control as needed.
For Channels A and B, the two ranges are +/-1V and +/-5V. Channel C offers a choice of +/-5V
or Pitch, a melody-friendly setting with a range of +/- 12 semitones (one octave) quantized
to precise semitone steps.
A set of Portamento Channel C buttons control whether Portamento is turned on or off for
each Step of Channel C.
A set of Trigger buttons control whether each step sends its voltage or not, allowing for
sparse and syncopated patterns.

6.1.3. CV Outputs

On the far right, there are CV outputs for each Channel, allowing the various voltage offsets
to be patched to any appropriate parameter.
The KBD CV label on the CHANNEL C OUT indicates that when nothing is plugged into the
patch point, the hard-wired behavior is for Channel C to control the pitch of the sequence,
with each Step offset above or below the key being pressed. This lets you transpose a
sequence based on what notes you play.
There's also an output labeled TRIG OUT EG1+2. This routes active Trigger signals where
desired. When nothing is plugged in, the Trigger signals are routed to the Envelope
Generators to play notes.
The Sequencer Panel might seem simple, but that simplicity lets you get into using it quickly,
and you'll soon discover for yourself all the interesting ways a sequential CV can be used to
add motion and complexity to each Preset.
