In addition to being able to transmit MIDI data, Circuit Mono Station is also equipped with
standard
CV + GATE
outputs which can send analogue note data to other compatible
equipment. The CV and GATE outputs are separate 3.5 mm jack sockets on the rear panel.
Note data is always present when a Pattern is playing, and the CV output will transmit the pitch
values of Oscillator 1. This means you can control the pitch of an external synth (e.g., Eurorack
module) with the
Osc 1 Range
,
Coarse
and
Fine
controls. The
CV
output is scaled at
1 V/octave and covers a range from 0 V to +7 V: MIDI Note #24 (C1) = 0 V;
MIDI Note #36 (C2) = +1 V, and so on. Linear scaling applies within octaves for the other notes.
The
GATE
output is a per-note pulse of +5 V amplitude, with a duration equal to the length of
the note and a rise time of 140 - 170 μs. The GATE pulse is output fractionally later than the CV
voltage to permit external equipment to stabilise its pitch before the note is turned on.
Circuit Mono Station also has an
AUX CV
output
7
, for connection to external synth modules.
AUX CV
is one of the eight destinations of the Modulation Matrix (see page 81), and you
can assign any of the Matrix sources to it. The voltage range is -5 V to +5 V. Be aware of the
necessity to carefully adjust the
Depth
control
40
if using multiple modulation sources, as the
matrix’s additive nature may introduce clipping.
Analogue
CLOCK IN
and
CLOCK OUT
connectors are also provided on Circuit Mono Station.
See “Analogue Clock Rates” on page 87 for full details.
