Step 2: Controls
(1) KEYBOARD – the keyboard has 32 semi-
weighted, full-size keys.
(2) TUNE – adjust the frequency of the main VCO
of the synthesizer.
(3) POWER – turn the synthesizer on or o. Make
sure all the connections are made before
turning on the unit. The LED shows when
power is applied and the unit is turned on.
Modulator Section
(4) LFO/CLK RATE – adjust the frequency of
the modulation LFO. The LED blinks at the
current rate.
(5) LFO RATE – select the frequency range of the
LFO rate fader from Low, Medium, or High.
(6) WAVEFORM – select the waveform from
triangular, square wave, random, or noise.
VCO Section
(7) MOD DEPTH – adjust the level of modulation
of the VCO.
(8) RANGE – select the overall frequency range
(octave) of the VCO from 16’, 8’, 4’, and 2’.
(9) PULSE WIDTH – adjust the pulse width of the
VCO when the pulse modulation source switch
is set to Manual. For LFO and ENV, it adjusts
the eect of the modulation.
(10) PULSE WIDTH MODULATION SOURCE–
select from LFO triangular waveform, Manual,
or Envelope.
Source Mixer Section
(11) PULSE – adjust the level of the
pulse waveform.
(12) SAW WAVE – adjust the level of the
sawtooth waveform.
(13) TRIANGULAR – adjust the level of the
triangular waveform.
(14) SUB OSCILLATOR – adjust the level of the
sub oscillator.
(15) SUB OSC TYPE – select the type of sub
oscillator, from 1 octave down, 2 octaves
down, or a narrower pulse width at 2
octaves down.
(16) NOISE – adjust the level of noise.
(17) EXT AUDIO – adjust the level of incoming
audio from an external source.
Sequencer Section
SEQUENCER – see details on page 16 and 36.
VCF Section
(18) FREQ – adjust the cuto frequency of the VCF.
Frequencies above the cuto are attenuated.
(19) RES – adjusts the amount of volume
level boost (resonance) given at the
cut-o frequency.
(20) ENV – adjust the amount of eect the
envelope has on the VCF.
(21) MOD – adjust the amount of eect the
modulation has on the VCF.
(22) KYBD – adjust the amount of eect the
keyboard has on the VCF.
(23) FM SOURCE – select the source of FM
modulation on the VCF from: pulse, sawtooth,
1 octave down square wave, 2 octaves down
square wave, 2 octaves down pulse, and noise.
(24) FM AMOUNT – adjust the eect of FM
modulation on the VCF.
VCA Section
(25) ENV/GATE – select if the VCA is aected by
the envelope controls, or by gate.
Envelope Section
When applied to the VCA, the ADSR envelope is used
to control the level of the note being played over
time. When applied to the VCF, the ADSR envelope
is used to control the cut-o frequency of the
lter for each note played over time. In addition,
the ADSR envelope can also aect the VCO pulse
width modulation.
Note that the ATTACK, DECAY and RELEASE stages are
measured in units of time, and the SUSTAIN stage is
measured in units of level.
(26) GATE + TRIG – a new envelope is triggered at
each key press.
GATE – when a new note is pressed, a new
envelope is trigged after the current one
is done.
LFO – the envelope is triggered by the LFO.
(27) A-ATTACK – this adjusts the time for the level
to reach maximum after a key is pressed.
(28) D-DECAY – this adjusts the time to decay
down to the SUSTAIN level after the attack
time is over.
(29) S-SUSTAIN – this sets the sustain level
reached after the attack and decay time
are over.
(30) R-RELEASE – this adjusts the time it takes for
the signal to decay once the key is released.
Control Section
(31) VOLUME – adjust the volume level of the
main output and headphones output. Turn
this down before turning the power on, or
before putting on headphones.
(32) GLIDE – adjust the amount of Glide time
(Portamento) between notes on the keyboard.
(33) GLIDE ON/OFF – turn the GLIDE on or o.
(34) TRANSPOSE – adjust the keyboard in one
octave steps, from Low, Medium, and High.
(35) VCO FADER – adjust the eect of the bender
controls on the VCO.
(36) VCF FADER – adjust the eect of the bender
controls on the VCF.
(37) LFO MOD FADER – adjust the amount of LFO
modulation added when the MOD switch
on the grip is pressed, or the BENDER (38) is
moved up.
(38) BENDER – move left or right to adjust the
frequency of the VCO and/or the cut-o
frequency of the VCF. The level of the eect
depends on the setting of the nearby VCO and
VCF faders. Move it up to add LFO modulation.
The modulation eect depends upon the
setting of the LFO MOD fader and other
LFO controls.
Rear Panel
(39) DC INPUT – connect the supplied DC
power adapter here. The power adapter
can be plugged into an AC outlet capable of
supplying from 100V to 240V at 50 Hz/60 Hz.
Use only the power adapter supplied.
(40) MAIN OUTPUT – connect this output to
the line-level inputs of mixers, keyboard
ampliers, or powered speakers for example.
(41) PHONES – connect your headphones to this
output. Make sure the volume is turned down
before putting on headphones.
(42) EXT AUDIO INPUT – this input can be
connected to the line level audio output from
an external audio device. Adjust the level
using the EXT AUDIO fader in the SOURCE
MIXER section.
(43) HOLD – an optional footswitch can be
connected here, to hold or release any
pattern playing in the Sequencer, and in
normal performance.
(44) VCF CV INPUT – the VCF can be controlled by
an external control voltage connected here.
(45) EXT CLK INPUT – an external clock signal can
be applied here.
(46) CV/GATE INPUT – these inputs allow the
connection of control voltage and gate signals
from compatible external devices such as
modular synthesizer equipment.
(47) CV/GATE OUTPUT – these outputs allow
the connection of control voltage and gate
signals to compatible external devices such as
modular synthesizer equipment.
(48) VELOCITY OUT – outputs a variable control
voltage based on the key velocity.
(49) MIDI Connections – these 3 standard 5-pin
DIN Jacks allow connections to other MIDI
equipment in your system.

source. This will commonly be another MIDI
keyboard, an external hardware sequencer, a
computer equipped with a MIDI interface, etc.
MIDI THRU – passes through MIDI data
received at the MIDI INPUT.
MIDI OUT – sends MIDI data to an application
(50) USB PORT – This USB type B jack allows
connection to a computer. The MS-1 will show
up as a class-compliant USB MIDI device,
capable of supporting MIDI in and out.
USB MIDI IN – accepts incoming MIDI data
from an application.
USB MIDI OUT - sends MIDI data to an
application.
(51) GRIP/ MOD – the connector
of the live performance grip attaches here.
Live Performance Kit
(52) BENDER – adjusts the frequency of the VCO
and/or the cut-o frequency of the VCF. The
level of the eect depends on the setting of
the VCO and VCF Bender faders. This control
only increases the frequency. The main unit
bender can also be used at the same time.
(53) MOD – press and hold to add LFO modulation.
The level of eect depends upon the setting of
the LFO mod fader, and the other LFO controls.
(54) CONNECTOR – t into the GRIP and MOD
connectors in the main unit rear panel.
(55) MOUNTING HOLES – t the supplied screws
in these holes to secure the handle to the left
side of the main unit.
(56) STRAP POINT 1 – connect one end of the
supplied strap here.
(57) STRAP POINT 2 – secure this to the right side
of the main unit with the supplied screws.
(58) STRAP – the supplied strap attaches to the 2
strap points.
