# A.2 SYN MACHINES

APPENDIX A: MACHINES
APPENDIX A: MACHINES
A machine is a module within the Digitone II with specific functionality. A machine can be switched out for
another machine in the same category. For example different synthesis engines or filters. Every machine
has a specific set of parameters tailored to give you the most relevant and useful sound-shaping possibili­
ties for that particular machine. For more information, please see “5.3.1 AUDIO TRACKS AND MACHINES”
on page 16
Use the [UP]/[DOWN] keys to select the parameter group's pages. You can also press a [PARAMETER]
key repeatedly to cycle trough the parameter pages in that group. Press and hold a [PARAMETER] key to
see the values for all parameters on that page.
A.1 ASSIGNING MACHINES TO THE ACTIVE TRACK
1.	 Press [FUNC] + [SYN] to open the MACHINE menu.
2.	 Use [LEFT]/[RIGHT] to navigate to the desired machine category.
3.	  Use [UP]/[DOWN] to select machine, and then press [YES] to assign the selected machine to the
track.
The rest of this appendix lists the machine-specific parameters on the SYN and FLTR pages. The selected
machine determines the parameters available.
A.2 SYN MACHINES
The SYN machines are different synthesis engines with unique functionalities. In this section you also find
the MIDI machine that lets you control external, MIDI equipped, gear. For more information, please see
“5.3.2 MIDI TRACKS” on page 17. You can assign any SYN machine to any track. Press [SYN] to access
these parameter pages.
A.2.1 FM TONE
The Digitone II's FM TONE machine is a four operator Frequency Modulation (FM) synth in the style of
the classic 80s implementations. However, unlike the early FM synths, the Digitone II use its FM engine
more like a complex tone generator than a complete synthesizer voice (although it does have this capa­
bility too). The Digitone II signal path is more similar to a typical subtractive synth than a classic FM voice.
PAGE 1
The parameters on the page 1 control various aspects of the FM engine. You can find more informa­
tion about the Digitone II FM synthesis in “APPENDIX B: THE FM TONE SYNTHESIS” on page 106.
ALGO
Algorithm selects the structure of how the four operators are connected to each other.
For more information, please see “B.3 ALGORITHMS” on page 107.
RATIO C
Sets the frequency ratio for operator C. For more information, please see “B.4 FM RATIOS” on page
107.

APPENDIX A: MACHINES
RATIO A
Sets the frequency ratio for operator A. For more information, please see “B.4 FM RATIOS” on page
107.
RATIO B
Sets the frequency ratio for operator B1 and B2. The minimum value for B1 and B2 is .25. As you
turn the encoder, B2 increases until it reaches the max (16). It then starts over from .25 and B1
increases to the next value (0.5). This revolving behavior continues until both operators reach
the maximum value. This parameter behavior is similar to the movement of the hands on a watch.
(0.25–16.0) For more information, please see “B.4 FM RATIOS” on page 107.
HARM
Harmonics controls waveform of the operators, C, A, and B1. The parameter is bipolar. Negative
parameter values change the harmonics of operator C, while positive parameter values change the
harmonics of operators A and B1. (-26.00–26.00) For more information, please see “B.6 HARMON­
ICS” on page 109.
DTUN
Detune offsets the ratio of operator A and B2. Up to a parameter value of around 64, the offset is
very slight to achieve subtle movement. Above 64 the operators start to detune more heavily.
FDBK
Feedback sets the amount of self modulation of the operator that has feedback. This operator is
shown in the algorithm on the screen with a feedback loop in its upper left corner. For more infor­
mation, please see “B.2 OPERATORS” on page 106.
MIX
Each algorithm has two carrier outputs (X and Y) that come from two different operators depend­
ing on what algorithm you chose. Use the MIX parameter to mix between these outputs so that
you can cross-fade between two separate timbres. (-64–63). For more information, please see For
more information, please see “B.3 ALGORITHMS” on page 107.
PAGE 2
The parameters on the page 2 control various aspects of the FM synthesis, mainly the amount of
frequency modulation together with the operator envelopes.
The FM engine has two operator envelopes. One is for operator group A, and one is for group B (B1
and B2). The envelopes are essentially expanded AD (Attack Decay) envelopes, but with an added
adjustable end level (the amplitude level the sound reaches at the end of the decay stage). For more
information, please see “B.5 OPERATOR ENVELOPES” on page 108.
ATK (A)
Attack Time sets the length of the attack phase of the modulation envelope for operator A.
DEC (A)
Decay Time sets the length of the decay phase of the modulation envelope for operator A.
END (A)
End Level sets the end level of the modulation envelope for operator A.
LEV (A)
Level sets the modulation amount from operator A.
ATK (B)
Attack Time sets the length of the attack phase of the modulation envelope for operator group B
(B1 and B2).

APPENDIX A: MACHINES
DEC (B)
Decay Time sets the length of the decay phase of the modulation envelope for operator group B
(B1 and B2).
END (B)
End Level sets the end level of the modulation envelope for operator group B (B1 and B2).
LEV (B)
Level sets the modulation amount from operator group B (B1 and B2).
The LEVEL parameter for B is macro mapped to both operator B1 and B2 and control their modula­
tion amount as per this graph:
B1

Level
Parameter value
If you wish to use frequency modulation, it is important that you turn the LEV parame­
ters up, since they set the amount of frequency modulation in the FM engine.
PAGE 3
The parameters on the page 3 control various aspects of the FM synthesis, mainly the amount of
frequency modulation together with the operator envelopes and their behavior.
ADEL
Envelope delay sets the time before attack phase of the modulation envelope for operator A starts.
Attack
End level
Decay
Delay
ATRG
Envelope trig sets the trig behavior of the operator envelopes. The envelopes can be either trig­
gered or gated - making it either an ADE (Attack Decay End) or an ASDE (Attack Sustain Decay
End) envelope. The sustain phase does not have an adjustable envelope level. It is instead the LEV
parameter that sets the sustain level. The note length defines the length of the sustain phase.

APPENDIX A: MACHINES
BDEL
Same as ADEL but for operator group B (B1 and B2).
BTRG
Same as ATRG but for operator group B (B1 and B2).
BRST
Same as ARST but for operator group B (B1 and B2).
PAGE 4
The parameters on the page 4 controls the operators ratio offsets and the key scaling.
RATIO OFFSET C, A, B1, B2
Adds offsets to the ratios of each of the four operators.
KEY TRACK A
Key track sets the level of how much the modulation output from operator A is affected by what
note you play on the keyboard. If you set key track to 0, the modulation level is the same for all
keys. A higher setting decreases the modulation level more and more the higher you play the key­
board. So, a lower level of modulation decreases the complexity of the tone in the higher frequen­
cies, which is a typical behavior in many acoustic instruments.
KEY TRACK B1
Same as KEY TRACK A, but for operator B1.
KEY TRACK B2
Same as KEY TRACK A, but for operator B2.
A.2.2 FM DRUM
The Digitone II’s FM DRUM machine is an FM engine specially tailored to produce drums and other per­
cussive sounds, although it also works well for melodic sounds. Below, you see the FM DRUM machine’s

Algorithm selects the structure of how the three operators are connected to each other.
OP.C
Operator C Wave sets the waveform for Operator C.

of the sound are excluded.) The wavefolding increases the complexity of the wave and creates a
more overtone rich sound.
PAGE 2

PAGE 3
HOLD
Body Hold sets the time before the decay phase starts for the body part of the sound.
DEC
Body Decay sets the length of the decay phase for the body part of the sound. The last value is
infinite.
PH.C
OP C Phase sets the reset of the phase for operator C. A parameter value less than 90 means that
phase reset is on, and the value represents the phase start position in degrees. At 90, the operator
resets at the peak of the waveform. When set to OFF (value 91), operator C’s phase is not reset.
LEV
Body Level sets the level of the body part of the sound.
NRST
Noise Reset will (when switched on) reset the noise to the same random seed on every note on.
This can be useful if you want the noise part to always sound the same, like if it was a sample.
NRM
Noise Ring Mod will (when switched on) use Operator C as ring modulator for the noise.
PAGE 4
NHLD
Noise Hold sets the time before the decay phase starts for the noise part of the sound.
NDEC
Noise Decay sets the length of the decay phase for the noise part of the sound. The last value is
infinite.
TRAN
Drum Transient selects between different transients.

APPENDIX A: MACHINES
BASE

(white noise) to low (grainy).
NLEV
Noise Level sets the level of the noise part of the sound.
A.2.3 WAVETONE
The WAVETONE machine is a two-oscillator synth engine with very flexible wave shaping possibilities,
borrowing elements from phase distortion, wavetables, ring modulation, hard sync, and adding flexible
noise design.
PAGE 1
TUN1
Osc1 Tune sets the pitch of oscillator 1.
WAV1
OSC1 Waveform sets the waveform for oscillator 1. The waveform crossfades between the differ­
ent waveforms. Which waveforms you can select here depends on what wavetable you select with
TBL1.
PD1
Osc1 Phase Distortion controls the amount of phase distortion of oscillator 1. Think of it as chang­
ing the pulse width, but on any waveform, not just square waves.
LEV1
Osc1 Level sets the level of oscillator 1.
TUN2
Osc2 Tune sets the pitch of oscillator 2.
WAV2
Osc2 Waveform sets the waveform for oscillator 2. The waveform crossfades between the differ­
ent waveforms. Which waveforms you can select here depends on what wavetable you select with
TBL2.
PD2
Osc2 Phase Distortion controls the amount of phase distortion of oscillator 2. Think of it as chang­
ing the pulse width, but on any waveform, not just square waves.
LEV2
Osc2 Level sets the level of oscillator 2.
Phase distortion makes the oscillator traverse the first and second half of the
waveform at different speeds, effectively distorting the waveshape by dragging its
midpoint towards the start or end. A simple example is the squarewave, where phase
distortion acts a pulsewidth parameter adjusting the duty cycle of the waveform.

APPENDIX A: MACHINES
PAGE 2
OFS1
Osc1 Lin Offset sets an offset of oscillator 1 tuning. This parameter offsets the frequency of the
oscillator linearly in hertz (unlike TUNE which adjusts the pitch in cents). This feature gives more
noticeable detune in lower notes than higher. It allows for a different kind of chorus-like detune,
since the beating frequency does not vary with the pitch.
TBL1
Osc1 Wavetable selects the wavetable for the oscillator 1 WAVE parameter. PRIM contains the ba­
sic oscillator waves Sin, Tri, Saw, Square. HARM contains a long list of waveforms sweeping across
other combinations of harmonics.
MOD
Oscillator Modulation selects how the two oscillators can interact with each other. The settings are
OFF, RING MOD, RING MODE FIXED (Osc 2 does not track note values), and HARD SYNC.
In RING MOD mode, Oscillator 2 is modulating Oscillator 1. In that configuration, you
most often don’t want to hear the modulator, so you would turn down LEV2 to 0.
TUN1 will adjust the tuning of the sound, while TUN2 will change the sound. Even if
LEV2 is set to 0, adjusting WAV2 and PD2 will impact the timbre of the sound.
In HARD SYNC mode, Oscillator 1’s phase is reset every time Oscillator 2’s waveform
starts a new cycle. In this mode, TUN2 controls the tuning of the sound, and TUN1 will
control another aspect of the sound, that may sound a bit like a filter with resonance
when modulated.
RSET
Oscillator Phase Reset sets if and how the oscillator's wave phase resets when you play a note.
OFF does not reset the oscillator phase. ON resets the oscillators to the start of their waveform
phase. RAND resets the oscillators to a random position in the waveform phase.
OFS2
Osc2 Lin Offset sets an offset of oscillator 2 tune. This parameter offsets the frequency of the
oscillator linearly in hertz (unlike TUNE which adjusts the pitch in cents). This feature gives more
noticeable detune in lower notes than higher. It allows for a different kind of chorus-like detune,
since the beating frequency does not vary with the pitch.
TBL2
Osc2 Wavetable selects the wavetable for the oscillator 2 WAVE parameter. PRIM contains the ba­
sic oscillator waves Sin, Tri, Saw, Square. HARM contains a long list of waveforms sweeping across
other combinations of harmonics.
DRIF
Oscillator Drift sets the amount of random pitch drift of oscillator 1 and 2.
PAGE 3

APPENDIX A: MACHINES
ATK
Noise Attack sets the length of the attack phase of the noise amp envelope.
HOLD
Noise Hold sets the length of the hold phase of the noise amp envelope. Fixed Hold time values
(0–126) specify the length of the hold phase, and the envelope ignores Note Off events such as Trig
Length, releasing a [TRIG] key or a key on an external controller. Setting HOLD to NOTE means the
hold phase will be determined by Note On and Note Off events.
If you set HOLD to NOTE and use an external keyboard to trigger the envelope, then
the sound will be sustained (if DEC is set to less than 127) for as long as you press a
key on the keyboard.
DEC
Noise Decay sets the length of the decay phase of the noise amp envelope.
NLEV
Noise Level sets the level of the noise part of the sound.
BASE
Noise Base sets the base frequency for the noise filter.
WDTH
Noise Width sets the frequency width above the base frequency for the noise filter.
TYPE
Noise Type selects between three different types of noise, GRAIN, TUNED (a Sample and Hold that
tracks the pitch, and S&H (Sample and Hold).
CHAR
Noise Character changes the character of the noise. The effect of this parameter vary depending
on the selected TYPE.
GRAIN, Character sets the density of the grain, from white noise to very grainy.
TUNED, Character sets the base tuning of the sample & hold that are then tracked by pitch.
S&H, Character sets the fixed tuning of the sample and hold.
A.2.4 SWARMER
The SWARMER machine is based on using one main oscillator and a swarm of six additional detuned
oscillators to create a rich sound.
PAGE 1
TUNE
Tune offsets the incoming note value. This parameter is bipolar. A setting of 0 leaves the pitch
unchanged.
SWRM
Swarm Waveform sets the waveform of the detuned swarm oscillators.
DET
Detune sets the amount of detuning of the six swarm oscillators in relation to the main oscillator.

APPENDIX A: MACHINES
MIX
Mix sets the level of the swarm oscillators in relation to the main oscillator.
M.OCT
Main Octave detunes the main oscillator down one or two octaves but leaves the swarm oscillators’
pitch unchanged.
MAIN
Main Waveform sets the waveform of the main oscillator.
ANIM
Swarm Animation sets the modulation amount of the swarm oscillators. The swarm oscillators are
modulated separately in pairs by hidden LFOs running at different rates.
N.MOD
Noise Modulation sets the amount of noise modulation of the detuned swarm oscillators.
A.2.5 MIDI
The parameters for the MIDI machine are split over the TRIG, SYN, FLTR and AMP PARAMETER pages.
The FX page contains no parameters The MOD pages are the same as for audio tracks, but there are
two LFOs available for MIDI tracks.
TRIG PAGE 1
Set the actions for when a note is trigged. Change settings using the DATA ENTRY knobs. These
general settings affect note trigs placed in the sequencer.
NOTE
Trig Note sets the pitch of the note when trigged. When in LIVE RECORDING mode and playing
in KEYBOARD mode, the pitch of the [TRIG] keys played will override this setting. Press and turn
DATA ENTRY knob A to select only note values that exist in the scale set by KB SCALE. For more
information, please see “8.5.2 KEYBOARD SETUP MENU” on page 25.
VEL
Trig Velocity sets the velocity of the sequencer’s note trigs.
LEN
Trig Length sets the length of the note trig. In LIVE RECORDING mode, the duration of pressing the
[TRIG] keys overrides this general setting.
PROB
Trig Probability sets the probability that the trigs on the track plays or not. The probability outcome
is re-evaluated every time a trig is set to play. The default setting is 100%, meaning that all the trigs
on the track plays every time. This parameter can be parameter locked which lets you give separate
trigs their own probability.
LFO.T
LFO Trig controls if the LFO will be trigged or not.
FILL
Fill is a separate trig condition that determines if a trig is active (plays) or not depending on if the
device is in FILL mode or not. For more information, please see “10.12.4 FILL MODE” on page 52,
and “10.12.3 TRIG CONDITIONS AND CONDITIONAL LOCKS” on page 51.
ON, A trig with FILL set to ON, plays when FILL mode is active.
OFF, A trig with FILL set to OFF plays when FILL mode is not active.

APPENDIX A: MACHINES
The sequencer needs to be in FILL mode to activate the FILL trig condition. For more
information, please see “10.12.4 FILL MODE” on page 52.
COND
(Trig Condition) when you add a conditional lock, COND sets the Trig Condition with which a set of
conditional rules can be applied to any trig, using a conditional parameter lock. For more informa­
tion, please see “10.12.3 TRIG CONDITIONS AND CONDITIONAL LOCKS” on page 51.
