CV TO MIDI CONVERSION
Sirin can convert multiple channels of Control Voltage to MIDI. This allows you to take CV sources
like a Moog Mother-32 and translate the voltage into MIDI for CV control over plug-in effects, soft
synths, or other MIDI gear.
WARNING: For optimal CV to MIDI conversion response, adjust the scale and range of the external
control voltage to stay within 0 to +5 Volts. Do not apply a negative control voltage, or a CV
greater than +5 Volts!

HEADPHONES
Sirin’s source signals are created by two Voltage-Controlled Oscillators (VCO) which are mixed with the External Audio Input. The Mixer
Output is routed to the Filter, where the tone is sculpted according to the
Filter parameters and the Filter ADSR Envelope. The signal is then passed
to the Amplifier (VCA) stage, where the Volume ADSR envelope shapes it.
Finally, the signal is routed to the Output section, where the final level is
set by the Volume control knob.
For most users, MIDI will be the main source of control for Sirin. Each time
Sirin receives a MIDI “Note On” command, it produces a Pitch CV and
Gate signal in response. The Pitch CV signal sets the Pitch of the Oscillators,
while the Gate signal triggers the Filter and Volume ADSR Envelopes.
The Sirin can also be operated via CV and Gate trigger connections,
for a more ‘old school’ method of control. Both control methods (MIDI &
CV/Gate) can be used at the same time, although some combinations of
control signals may cause unpredictable results.
NOTE: DIN MIDI IN is not passed to USB MIDI OUT
8
BASIC OPERATION
The Sirin responds to MIDI messages on both DIN and USB MIDI Inputs.
In addition, Sirin’s knobs and switches transmit MIDI Control Change
(CC) commands via MIDI USB, allowing parameter adjustments to be
captured by any MIDI-recording device. Sirin has an LED MIDI indicator
that indicates MIDI activity on either the DIN MIDI or USB MIIDI connector.
To further extend the Sirin’s capabilities, there are additional parameters
that can be accessed via MIDI control. A complete list of all MIDI CC commands
can be found on page 22-23.
THE COMPONENTS
OSCILL ATORS
The Oscillators are the main sound source of Sirin.
They create electronic vibrations that can be tuned
and amplified into sound that we can hear. The
Sirin’s VCOs can produce a total musical range
of 6 octaves.
OSCILLATOR 1 (VCO 1) serves as a master Oscillator
to which OSCILLATOR 2 (VCO 2) is tuned. Two
independent switches select the waveform for
each Oscillator (Sawtooth or Square). A FINE TUNE
control adjusts the master tuning of both Oscillators.
The frequencies of both Oscillators are affected by a number of sources. The
main source is a ‘Note On’ command transmitted from an external MIDI
controller or DAW. The ‘Note On’ command is translated into a Control
Voltage that allows the Oscillators to be played in an equal-tempered scale.
Other control sources include Sirin’s GLIDE circuit, VCO 2 FREQ, the
PITCH CV INPUT, the FINE TUNE control, and the output of the MODULATION
(LFO) circuit.
PANEL CONTROLS FOR THE OSCILLATOR
OSCILL ATOR 1 Switch (CC# 70):
Selects a Sawtooth (LED OFF) or Square wave (LED ON) for VCO 1.
OSCILL ATOR 2 Switch (CC# 71):
Selects a Sawtooth (LED OFF) or Square wave (LED ON) for VCO 2.
VCO 2 FREQ (CC# 17):
Sets the frequency offset of VCO 2 from VCO 1. The offset range is +/-1
octave. Center position tunes VCO 2 in unison with VCO 1.
9
FINE TUNE:
Adjusts the frequency of both VCOs by approximately +/-1 semitone. The
FINE TUNE control does not transmit MIDI.
MIDI ACCESSIBLE CONTROL
VCO 2 BEAT (CC# 18):
Selects the fine frequency offset for VCO 2. The adjustment range is
+/- 50 cents.
Default = 64.
NOTE SYNC (CC# 81):
When enabled, NOTE SYNC forces both oscillators to start at the same
time, eliminating any phase differences at the start of each “Note On”
command. This ensures energy is consistent at the start of each new note.
Default = OFF.
EXTERNAL CONTROL
The PITCH CV jack on the back panel is a CV input for external control of
the Oscillator pitch. This input controls the frequencies of both Oscillators.
A 1 volt change of this voltage will change the pitch by one octave. The
jack accepts 0 to +5 volts, or an expression pedal like the Moog EP-3.
PERFORMANCE TIPS:
• For punchy bass lines, tr y using NOTE SYNC to keep the
energy at the beginning of each note the same.
• A steady control voltage applied to the PITCH jack will
offset the base pitch of both oscillators. You can use this
feature to transpose the oscillators to any desired interval.
• To recreate the classic Taurus sound, choose the Sawtooth
wave for one or both oscillators.
10
GLIDE
GLIDE (AKA ‘portamento’) is a musical effect that makes smooth
changes in pitch between notes. Sirin’s GLIDE RATE is adjustable
from instantaneous to extremely long.
PANEL CONTROLS FOR GLIDE
GLIDE Switch (CC# 65):
Enables/Disables the GLIDE function. GLIDE is on when the LED is on.
GLIDE RATE (CC# 5):
Sets the rate of GLIDE that occurs when the note controlling Sirin changes.
MIDI ACCESSIBLE CONTOL
GLIDE TYPE (CC# 92):
Sirin offers three GLIDE types: Linear Constant Rate (LCR), Linear Constant
Time (LCT), or Exponential (EXP). When LCR is selected, the GLIDE RATE stays
the same regardless of the interval. When LCT is selected, the GLIDE TIME stays
the same regardless of the interval. When EXP is selected, the GLIDE RATE follows
an exponential curve that starts fast and then slows as it approaches the target
note (like the Taurus).
Default = LCR.
LEGATO GLIDE (CC# 83):
Normally, GLIDE occurs with every new note. When LEGATO GLIDE is enabled,
however, GLIDE is only applied when a new note is received while another note
is still being held.
Default = OFF.
MIX (OSCILLATOR LEVELS)
Each Oscillator (VCO 1 & VCO 2) has a dedicated level
knob that allows you to control the relative strength of
each oscillator from 0 to 100%. NOTE: The VCOs begin
to clip the filter at about 2 o’clock creating more
agressive sounds.
PANEL CONTROLS FOR THE MIXER
VCO 1 LVL (CC# 15):
Sets the level of VCO 1.
11
VCO 2 LVL (CC# 1 6):
Sets the level of VCO 2.
MIDI ACCESSIBLE CONTROL
EXTERNAL INPUT LEVEL (C C# 27 ):
Adjusts the External Audio Input level. By default, the level is set for unity
gain, but the level can be adjusted up to 200%
Default = 64.
FILT E R
The FILTER is a classic Moog 24dB/
Octave Low-Pass Filter design with
resonance. It has controls for CUTOFF
frequency which determines the range
of frequencies the filter will affect, as
well as RESONANCE, which determines how much emphasis is applied to the
harmonics near the Cutoff frequency (see figure).
The FILTER provides either fixed or
dynamic timbre modifications. Dyna-
mic changes are provided by the
Filter Envelope Generator (EG), a Low
Frequency Oscillator (LFO), or by an
externally applied Control Voltage.
Amplitude
Frequency
Frequency response of a Low Pass Filter
with Resonance
Resonant Peak
PANEL CONTROLS FOR THE FILTER
CUTOFF (CC# 19):
Adjusts the CUTOFF frequency of the Low Pass Filter from 20 Hz to 20 KHz.
As the knob is rotated clockwise, the cutoff frequency is increased, allowing
more harmonics to pass through the filter, resulting in a brighter sound.
Conversely, as the knob is rotated counterclockwise, the sounds get darker.
NOTE: The Sirin may not produce sound when this control is turned all
the way down.
RESONANCE (RES) (CC# 21):
Sets the amount of signal sent from the FILTER output to be fed back into
it’s input. This creates a peak in the frequency that can be increased all the
way to self-oscillation.
12
EG AMOUNT (CC # 22):
The EGs are started by a Gate or MIDINote message. Once started, their shape in time is set by the ATTACK, DECAY/RELEASE, and SUSTAIN controls, as well as the Release switch and length of the Note played.
ENVELOPES
PANEL CONTROLS FOR THE ENVELOPES
FILTER ATTACK(CC# 23):Sets the time it takes for the Attack portion of the Filter EG to rise fromzero to maximum. The Attack time ranges from 1 msec to 30 seconds.
FILTER DECAY/RELEASE (CC# 24):Sets the time for the Decay and Release portion of the Filter EG. When a note is held, and the Attack time end is reached, the Decay portion of the EG starts. During the Decay portion, the EG moves to the Sustain level. When anote is released, the EG moves back to zero at the rate set by this control. This time ranges from 1 msec to 30 seconds. The Release segment of the Envelope is determined by the state of the RELEASE switch (ON/OFF).
FILTER SUSTAIN (CC# 25):Sets the Filter EG level after the Decay and before the Release portion. A note must be held longer than both the Attack and Decay time to reach the Sustain level. The level is adjustable from 0 to 100%.
AMPLIFIER ATTACK(CC# 28):
Sets the time it takes for the Attack portion of the Amplifier EG to rise from
zero to maximum. The Attack time ranges from 1 msec to 30 seconds.
AMPLIFIER DECAY/RELEASE (CC# 29):
Sets the time for the Decay and Release portion of the Amplifier EG. When
a note is held, and Attack time end is reached, the Decay portion of the EG starts. During the decay portion, the EG moves to the Sustain level. When a
Determines how much the Filter Envelope Generator (EG) adds to or
subtracts from the Filter Cutoff control setting. When the EG AMOUNT knob
is set to positive (+), turn the FILTER CUTOFF knob left to hear the ef fect.
When the EG AMOUNT knob is set to negative (-), turn the FILTER CUTOFF
knob right to hear the effect. Note that if the Cutoff frequency is set very high,
a positive EG Amount may have little or no noticeable effect, regardless of the
setting. Similarly, if the Cutoff frequency is set low, a negative EG Amount may
have little or no noticeable effect.
MIDI ACCESSIBLE CONTROL
FILTER KB TRACKING (CC# 20):
Determines how the Filter Cutoff changes in response to MIDI Note On
values. Filter tracking is adjustable from 0 to 200%.
Default = 32 (about 50%).
FILTER VELOCITY SENSITIVITY (CC # 89) :
Sets the amount OF MIDI Note velocity to the Filter.
Default = 64.
EXTERNAL CONTROL
The FILTER CV jack on the back panel is an input for external control of the
Filter Cutoff parameter. A voltage applied to this jack is added to the setting
of the Filter Cutoff control. A one-volt change in the Control Voltage will
change the cutoff frequency of the filter by about one octave. The jack
accepts 0 to +5 volts, or an expression pedal like the Moog EP-3.

ENVELOPES
ENVELOPE GENERATORS (EGs) add motion to
a sound after a note is played. The Sirin has
two separate Minimoog style Envelope Generators that affect the brightness and loudness of
the Sirin's sound by modulating the Filter
Cutoff (VCF) and Volume (VCA).
The EGs are started by a Gate or MIDI
Note message. Once started, their
shape in time is set by the ATTACK,
DECAY/RELEASE, and SUSTAIN controls,
as well as the Release switch and length
of the Note played.
PANEL CONTROLS FOR THE ENVELOPES
FI LT E R ATTACK (CC# 23):
Sets the time it takes for the Attack portion of the Filter EG to rise from
zero to maximum. The Attack time ranges from 1 msec to 30 seconds.
FILTER DECAY/RELEASE (CC # 24):
Sets the time for the Decay and Release portion of the Filter EG. When a
note is held, and the Attack time end is reached, the Decay portion of the EG
starts. During the Decay portion, the EG moves to the Sustain level. When a
note is released, the EG moves back to zero at the rate set by this control.
This time ranges from 1 msec to 30 seconds. The Release segment of the
Envelope is determined by the state of the RELEASE switch (ON/OFF).

A note must be held longer than both the Attack and Decay time to reach
the Sustain level. The level is adjustable from 0 to 100%.
AM P L IFIER AT TACK (CC# 28):
Sets the time it takes for the Attack portion of the Amplifier EG to rise from
zero to maximum. The Attack time ranges from 1 msec to 30 seconds.
AMPLIFIER DECAY/RELEASE (CC# 29):
Sets the time for the Decay and Release portion of the Amplifier EG . When
a note is held, and Attack time end is reached, the Decay portion of the EG
starts. During the decay portion, the EG moves to the Sustain level. When a
14
note is released, the EG moves back to zero at the rate set by this control.
Oscillator (LFO) is a signal used to move the pitch of VCOs and the Filter Cutoff
up and down automatically. A LFO can be used to simulate vibrato, create
wobbling filter sweeps, or make interesting synthesizer sounds.
MODULATION (MOD)
PANEL CONTROLS FOR MODULATION
LFO RATE (CC# 3):
Sets the frequency of LFO Modulation. The range is from 0.01Hz to 100Hz.
VCO LFO AMOUNT (CC# 13):
Sets the maximum amount the LFO moves the VCOs pitch up and down,up to +/- 1 octave. Modulation affects both Oscillators. Amounts above MIDINote 72 are clipped. If using a MIDI controller, the Mod Wheel (CC# 1) is
used to fade the LFO Pitch Modulation in and out.
VCF LFO AMOUNT (CC# 12):Sets the maximum amount the LFO moves the Filter Cutoff up and down,
up to +/- 5 octaves. Amounts above 20KHz or below 20 Hz are clipped. Ifusing a MIDI controller, the Mod Wheel (CC# 1) is used to fade the LFO
Filter Modulation in and out.
MIDI ACCESSIBLE CONTROL
LFO MIDI SYNC ON/OFF (CC# 87):Enables or Disables the ability of the Sirin’s LFO to sync to MIDI
Clock messages.
Default = ON.
LFO SYNC CLOCK DIVISION (CC# 86):Selects the LFO Clock division when the LFO Sync Source is set to MIDIClock. LFO Division Settings are listed on page 24. The LFO RATE controlcan also act as a Clock Divider.Default = ON.
LFO KEY TRIGGER (CC# 82):Re-triggers the start of the LFO cycle when a NOTE ON message or KB GATEControl Voltage is received.Default = OFF.
NOTE: When the Sirin powers up, the settings on the VCO LFO AMOUNT and VCF LFO AMOUNT controls have a direct effect on the VCO and VCF. This behavior continues until Sirin receives a MIDI Mod Wheel command, from which point the Mod Wheel takes master control of the LFO modulation amount set by the Amount controls.
The time ranges from 1 msec to 30 seconds. The Release segment of the
Envelope is determined by the state of the RELEASE switch (ON/OFF).
AMPLIFIER SUSTAIN (CC # 3 0):
Sets the Amplifier EG level after the Decay and before the Release portion.
A note must be held longer than both the Attack and Decay time to reach
the Sustain level. The level is adjustable from 0 to 100%.
MIDI ACCESSIBLE CONTROL
OUTPUT (VCA) VELOCITY SENSITIVITY (CC # 9 0):
Sets the amount of MIDI Note velocity to the Amplifier.
Default = 64 (50%).
EXTERNAL CV CONTROL
The GATE jack on the back panel is a trigger input that accepts a +5V Gate
signal. Applying a Gate signal causes both Envelopes (Amplifier and Filter)
to trigger simultaneously. NOTE: When a Gate signal is applied, it overrides
triggering via MIDI. You will still be able to control the Oscillator pitch and
Modulation amounts from a MIDI controller, but the envelopes will not
retrigger until the Gate trigger is removed.
RELEASE
The RELEASE switch enables or disables the Release segment of
both Envelope Generators. When enabled, the Envelope Release
time is the same as the Envelope Decay time, and the DECAY
control adjusts the time for both segments. When disabled, the
Release segment does not occur and the Envelope stops abruptly in response
to a “Note Off” message (or when the Gate CV goes to zero).
PANEL CONTROL FOR RELEASE
RELEASE Switch (CC# 68):
Enables/Disables the Release function for both Envelope Generators.
RELEASE is enabled when the switch LED is ON.

MODULATION (MOD)
MODULATION is an important part in the creation of musically-expressive sounds. Sirin’s
MODULATION section provides an LFO with adjustable
RATE and AMOUNT controls for the oscillators
(VCO) and the Filter (VCF). The Low Frequency
Oscillator (LFO) is a signal used to move the pitch of VCOs and the Filter Cutoff
up and down automatically. A LFO can be used to simulate vibrato, create
wobbling filter sweeps, or make interesting synthesizer sounds.
PANEL CONTROLS FOR MODULATION
LFO RATE (CC# 3):
Sets the frequency of LFO Modulation. The range is from 0.01Hz to 100Hz.
VCO LFO AMOUNT (CC # 13) :
Sets the maximum amount the LFO moves the VCOs pitch up and down,
up to +/- 1 octave. Modulation affects both Oscillators. Amounts above MIDI
Note 72 are clipped. If using a MIDI controller, the Mod Wheel (CC# 1) is
used to fade the LFO Pitch Modulation in and out.
VCF LFO AMOUNT (CC # 12):
Sets the maximum amount the LFO moves the Filter Cutoff up and down,
up to +/- 5 octaves. Amounts above 20KHz or below 20 Hz are clipped. If
using a MIDI controller, the Mod Wheel (CC# 1) is used to fade the LFO
Filter Modulation in and out.
MIDI ACCESSIBLE CONTROL
LFO MIDI SYNC ON/OFF (CC# 87):
Enables or Disables the ability of the Sirin’s LFO to sync to MIDI
Clock messages.
Default = ON.
LFO SYNC CLOCK DIVISION (CC# 86):
Selects the LFO Clock division when the LFO Sync Source is set to MIDI
Clock. LFO Division Settings are listed on page 24. The LFO RATE control
can also act as a Clock Divider.
Default = ON.
LFO KEY TRIGGER (CC# 82):
Re-triggers the start of the LFO cycle when a NOTE ON message or KB GATE
Control Voltage is received.
Default = OFF.
NOTE: When the Sirin powers up, the settings on the VCO LFO AMOUNT
and VCF LFO AMOUNT controls have a direct effect on the VCO and VCF. This
behavior continues until Sirin receives a MIDI Mod Wheel command, from
which point the Mod Wheel takes master control of the LFO modulation amount
set by the Amount controls.

VOLUME (VCA)
INPUT/OUTPUT PANEL
The back panel provides all of the input and output connections. In addition
to AUDIO INPUT/OUTPUT jacks, there are CV and GATE inputs, connections forMIDI, and the Power Connector. The Sirin does not have a power switch.
12VDC (POWER INPUT)
A barrel connector that accepts a +12VDC, tip positive power input fromthe power adaptor, which accepts 100-240 VAC, 50-60Hz.
CONTROLLER INPUTS
The PITCH, FILTER and VOLUME CV jacks supply power and will accept anexpression pedal such as the Moog EP-2, or a Control Voltage from 0 to+5 Volts. The GATE input accepts a +5 Volt trigger signal.
MIDI (DIN AND USB)
Connections for DIN MIDI input and USB MIDI IN-OUT.
AUDIO IN
The AUDIO IN jack allows an external audio source to be mixed with the
Sirin’s VCOs, and then routed to the Filter for processing. Although
the Sirin has no provisions for adjusting the level of this input on
the front panel, the level is adjustable up to 200% via MIDI CC# 27.
AUDIO OUT
The AUDIO OUT jack provides an unbalanced line-level signal for conne-cting to an amplifier or mixer.
HEADPHONE OUTPUT
1/8” minijack for stereo Headphone Output. 32Ω or higher recommendedimpedance.
BACK PANEL
The Sirin features a monophonic Audio Output and a Headphone
Output; both outputs appear on the back panel. Both ouputs are
adjusted simultaneously by the VOLUME control.
PANEL CONTROL FOR VOLUME
VOLUME:
Adjusts the output of the Voltage Controlled Amplifier (VCA) and Head-
phone levels. Rotating the control fully clockwise produces the maximum
output. Rotating the control fully counterclockwise silences the Sirin.
The VOLUME control does not transmit or receive MIDI. This is a post VCA
control.
MIDI ACCESSIBLE CONTROL
OUTPUT LEVEL (CC# 7):
Adjusts the Audio Output and Headphone volume levels.
VOLUME VELOCITY SENSITIVITY (CC# 90):
Velocity scales the amplitude of the Amplifier envelope Similar to tradit-
ional touch sensitivity.
Default = 64 (50%).
EXTERNAL CONTROL
The VOL CV jack on the back panel is an input for external control of the
Output level. A voltage of 0 Volts silences the Sirin and a voltage of
5 Volts corresponds to the output level set by the VOLUME control knob.
The jack accepts a positive Control Voltage from 0 to 5 Volts, or an expression pedal like the Moog EP-2.

PERFORMANCE TIPS:
• You can use the Sirin to process any audio signal simply
by plugging into the AUDIO IN jack. To hear the external
audio signal, you will need a MIDI NOTE ON message. To
hear the external audio signal without issuing a MIDI NOTE
ON message, apply +5V to the GATE jack. This will leave
the Gate open, and the Amplifier Envelope will remain at
its Sustain level until the Gate closes.
• The Sirin’s audio input is not limited to processing
monophonic signals - it can work well for processing
polyphonic signals, too. For example, connect the MIDI
Output of a MIDI-equipped polyphonic keyboard to the
Sirin’s AUDIO IN jack, and turn the MIX level of VCO 1
and VCO 2 all the way down on the Sirin. Now you
have a polyphonic source affected by the Sirin’s
Filter and Envelope circuits - a great way to warm up a
sterile digital signal!
19
MIDI OPERATIONS
MIDI CHANNEL
Sirin sends and receives on a single MIDI channel. By default, the
Sirin is set to MIDI Channel 1, but it can be set to any MIDI Channel
(1-16). To change the MIDI Channel on the Sirin:
1. Connect your MIDI controller or DAW to the Sirin.
2. Adjust the controller (or DAW) to transmit the desired
MIDI Channel.
3. On the Sirin; press and hold all four panel switches
(VCO 1 Wave, VCO 2 Wave, GLIDE and RELEASE). The panel
switch LEDs will blink, indicating that the Sirin is
waiting to set the new MIDI channel. The next MIDI message
that the Sirin receives (a Note On, CC, Pitch Bend etc...)
will set the new channel.
4. Once in learn mode, press a key on the MIDI controller(or
send MIDI data from the DAW). The Sirin will reset its MIDI
channel to match the channel being sent.
Changes to the Sirin’s MIDI channel are written to memory and
are remembered on power down.
PITCH BEND RESPONSE
By default, the PITCH BEND RESPONSE of the Sirin is set to +/- 3
semitones. The Pitch Bend up and down values can be adjusted
independently by issuing new values for MIDI CC#107 (Pitch Bend UP)
and CC# 108 (Pitch Bend DOWN). See the MIDI CC Messages Table for
the range of values.
MODULATION WHEEL (MOD WHEEL) RESPONSE
MIDI Mod Wheel messages control the maximum amount of modulation
effect set by the VCO LMO AMT and VCF LFO AMT controls (MIDI CC# 1).
20
MIDI CONTROL CHANGE (CC) MESSAGES
SECTION
The tables on the following pages list all MIDI CC messages for the
Sirin. Messages shown with an (M) indicate parameters which are
only accessible via MIDI. Bolded values indicate the appropriate range
for 7-bit messages (MSB).
NOTES:
• Sirin sends 7-bit MIDI CC messages for all parameters . It
can receive either 7-bit or 14-bit values for the parameters
controlled by knobs, but only 7-bit values for parameters con trolled by switches.
• For all parameters, the MSB indicates the ‘regular’ CC number,
and the LSB indicates the high-resolution ‘fine’ control value.
If you are only sending 7-bit MIDI CC messages to the Sirin,
use the MSB number by itself. Note that when MSB-only
messages are issued, the value range is always 0-127.
A NOTE ABOUT CONTROL PARAMETERS
LOCAL CONTROL OFF (CC# 122 ):
This parameter allows the front panel controls to send MIDI, but disconnects
the Sirin sound engine from direct control by the panel. Per the MIDI
spec, only values of ‘0’ and ‘127’ work (0 = OFF, 127 = ON). If you are connected to a DAW using USB MIDI patched through, you may need this to
avoid feedback artifacts. After changing the state of LOCAL CONTROL
on/off, the Sirin remembers the last setting after power down.
ALL SOUNDS OFF/ALL NOTES OFF (CC 120 or 123):
Both of these parameters are MIDI ‘panic’ functions that are used to silence
hung MIDI notes. Controllers or DAWs may send one or the other command
which is why the Sirin will respond to either.
