68 ARTURIA – KeyStep – USER’S MANUAL
10.9.4.2 Gate CV Output
We’ve included three types of Gate signal response:
S-trig: This stands for "Short-circuit trigger", though sometimes it’s called "negative
trigger". It involves keeping the voltage high and then shorting the trigger circuit
whenever the note should play. This format is used by Dr. Bob’s classics, Korg and
Yamaha synths, among others.
V-trig: An abbreviation for "Voltage trigger", also known as "positive trigger". This
method involves keeping normally low voltage on trigger and producing a fixed positive
voltage to indicate a note is on. It’s favored by Roland and Sequential Circuits synths
and others as well.
10.9.4.3 MIDI Note reference (0V, 1V)
KeyStep provides the option to set a separate reference note for both Volt per Octave
and Hertz per Volt formats. This parameter will change from a 0V reference to a 1V
reference depending on which Pitch CV Output option is selected.
Volts per octave uses a 0V MIDI note reference
Hertz per Volt uses a 1V MIDI note reference
10.9.4.4 Note Priority
Since CV connectors are always monophonic, it’s important to be able to determine
which note from a polyphonic sequencer track or keyboard will be interpreted as the one
the mono synth on the other end should play.
And even some mono synths prefer one or the other of the three choices KeyStep gives
you: Low note priority, High note priority, or Last note priority.
10.9.4.5 Mod CV source
This parameter determines which KeyStep feature will send signals to the Mod CV
output: the Mod strip, velocity or aftertouch.
10.9.4.6 Mod CV max voltage
Each of the three sources has a ‘zero’ point that translates into 0 Volts. This parameter
lets you specify whether the range will be 0-5V, 0-6V, etc., on up to 0-12V.
10.9.4.7 Pitch Bend Range
This parameter sets the maximum about the Pitch CV output will vary when the Pitch
strip is used.
