Introduction
In a choir, a string- or brass section, every voice has its own character, its sonic individuality, its proprietary modulation and its specific decay. Is this not possible for a polyphonic synthesizer? It is with the PerFourMer MKII! Each of its four voices are totally independent. No matter whether you play four single solo voices, a fourfold unison stack or with fourfold polyphony, the PerFourMer MKII will always generate all its voices on a complete indi­vidual basis. During development of the MKII-version, we focused to make this synthesizer as easy to operate and ergonomic as possible. The large housing and new designed knobs guarantee immediate access to each parameter of every synthesizer voice. PerFourMer MKII is an analogue syn­thesizer with exceptional sonic possibilities for use on stage and in studios. And we are sure; its design will assure you having a lot of fun with it.

Getting Started
You should find the following items in the box:
• 1 PerFourMer MKII unit
• 1 power chord
• 1 set of rack brackets + mounting material
• this manual
Connections and Powering
If you came here without any problems, you can finally start up the Per­FourMer MKII:
1. Connect the provided power chord to the PerFourMer MKII and a power outlet.
2. Connect the stereo outputs, located on the rear, to appropriate audio inputs of a mixing console, an audio-interface or an amplifier.
3. Connect the PerFourMer MKII's MIDI input to the MIDI output of a key­board, a hardware-sequencer or a MIDI-interface, connected to your DAW.
4. Press the POWER button to switch the PerFourMer MKII on. The blue status LED above the MASTER TUNE control will now be lit blue.
5. Congratulations, the PerFourMer MKII has now been started.
Components and Controls
On one hand, the PerFourMer MKII is a four-voice polyphonic analogue syn­thesizer with a classic voice structure. On the other hand, it o!ers four independent synthesizer channels. These can either be used individually or combined and played in some unique ways. The four synthesizer channels are all independent synthesizers with a classic structure of VCO-VCF-VCA. Tiny di!erences appear only when combining these synthesizers. We will now take your through the di!erent sections and the corresponding control elements.

Oscillator Section
Oscillators form the base of every synthesized sound. They o!er di!erent waveform shapes to create various audio spectra. Each PerFourMer MKII voice o!ers a voltage controlled analogue oscillator (VCO), four VCOs in total. Every VCO generates sine, triangle, square and saw tooth waveforms with octave positions 32’, 16’, 8’ and 4’. Alternatively, white noise or an external audio input can be selected for each synthesizer channel.
The following controls are available:
Picture 1: The oscillator section
WAVE
selects the waveform shape for the VCO. Available are: sine ( ), triangle (
), square ( ), saw tooth ( ) or noise ( ). With EXT selected, the oscillator signal is replaced by the audio signal fed into the EXT IN/VCO OUT input (see "Connections of the Synthesizer Channels", page 21).
NOTE The pulse width of the square waveform does not
have a dedicated control. However, it can be varied using the modulation wheel (MIDI CC #1). This func­tion can be enabled/disabled using EDIT PARAMETER 2: MODULATION WHEEL (PWM). (see "Edit-Mode", page 29).
Owner's Manual VERMONA PERfourMER MKII

Page 8
OCTAVE
sets this oscillator's base octave to 32', 16', 8' or 4'.
In setting "HI" and "LO" the oscillator doesn't respond to incoming pitch information. The oscillator constantly oscillates with a fixed frequency.
GLIDE
sets the duration of the glide-e!ect. This defines the time period for the pitch to travel from one note to the next played note. This function is also referred to as portamento or slide. It is well suited for solo work. With GLIDE set to zero, there will be no pitch-transitional-e!ect.
The glide-e!ect can also work automatically. This AUTO-function can be enabled/disabled using EDIT PARAMETER 5. With AUTO GLIDE enabled, the glide-e!ect will only be active with notes played legato, meaning a second note is played while the first note is still held. When not playing legato, the glide-e!ect will be inactive with AUTO GLIDE activated. To activate the PerFourMer MKII's legato-function see chapter "Envelope Generator" (See page 20).
EG INT
This control sets the modulation amount of the envelope generator towards the oscillator's pitch. Modulation can be applied positive or negative. In its center-position, modulation is turned o!. This control o!ers a center-catch.
TUNE
this control tunes the oscillator continuously within a range of approx. ±7 semitones.
LFO INT
sets the modulation intensity for the LFO targeting the pitch or the pulse width of the oscillator. In its center position, the modulation is turned o!. This control o!ers no center catch to allow for sensitively adjusted vibrato-e!ects.
Turning LFO INT clockwise from center position will introduce pitch modulation of the oscillator. With a sine wave selected for the LFO, this results in a classic vibrato while using the Sample & Hold waveform (S/H) will create random melodies and, at high speeds, e!ect-sounds.
Turning LFO INT counterclockwise from center position introduces pulse width modulation of the oscillator's square waveform. This function is
Owner's Manual VERMONA PERfourMER MKII
- 8 -
Page 9
dysfunctional with any other selected waveform. Using a sine waveform to modulate the pulse width results in a sound-thickening-e!ect, comparable to a slight detuning. With higher modulation intensities (70 % and higher), the oscillator will temporarily be muted depending on the LFO speed. Here, there pulse width is so narrow and the sound therefore partially inaudible. Use the LFO's square and Sample & Hold waveforms to take advantage oft this e!ect and create interesting rhythmical sound breakups.
NOTE The oscillator's pulse width can also be adjusted
using the modulation wheel (See page 7).
Extended Oscillator Functions
Oscillator synchronization
The PerFourMer MKII oscillators in synthesizer channels 2, 3 and 4 can be synchronized to their prior located counterparts. Here, the master oscillator will force its frequency upon its coupled partner. Whenever the master oscillator's waveform reaches a zero-pass-through, it will force the coupled oscillator to a pass-through, too. With two oscillators running at the same frequency, this function will eliminate all pulsing and lead to identical phases.
With the coupled oscillator's frequency set higher than the master oscillator, oscillator synchronization will lead to the generation of additional harmon­ics. Especially, a modulation of the coupled oscillator by an envelope gener­ator or LFO will result in complex harmonic structures.
To activate oscillator synchronization, set the SYNC switch to the left into VCO position.
For example, set switch
to VCO. Here, synthesizer channel 1 will act as master and synchronize synthesizer channel 2. The same is true for VCO 2 to VCO 3 and VCO 3 to VCO 4. It is of course possible to activate multiple sync switches at the same time. The dependencies will remain as described. However, modulation of multiple VCOs will lead to unforeseeable results and interesting e!ect sounds.
Owner's Manual VERMONA PERfourMER MKII

Page 10
NOTE To achieve a classical sync-sound, set the coupled
oscillator at least two octaves higher than the master oscillator or make sure, it heavily modulated by an envelope generator. It is also recommended to use a square waveform for the master-oscillator. However, other settings will also lead to good results.
Frequency modulation of oscillators
The PerFourMer MKII o!ers frequency modulation for the oscillators in syn­thesizer channels 2, 3 and 4. In each case, the modulation takes place through the prior located synthesizer channel. This means, oscillator 2's pitch is modulated by synthesizer channel in dependence of the played pitch. In other terms, oscillator 1 would be regarded as "modulator" and oscillator 2 as "carrier". This modulation chain can be continued all the way to oscillator 4. In opposite to the oscillator synchronization, the full synthe­sizer channel acts as modulator, including its settings for the filter, VCA and envelope.
Use the FM-controls of synthesizer channels 2-4 to set the intensity for the frequency modulation. Set to center, modulation will be turned o!. Turning the control to the left (towards VCO), will increase modulation intensity.
Turning the control clockwise (towards VCF) results in cuto! frequency modulation (See page 13).
NOTE Clean FM-sounds are achieved using sine waveforms
for carrier and modulator. In case, a frequency modulation of the oscillator does not deliver the desired result, you may try modulating the filter in a resonating state and with 100% key tracking. In most cases, this results in well playable sounds (See page
13)
Owner's Manual VERMONA PERfourMER MKII
- 10 -
Page 11
NOTE The PerFourMer MKII's FM-function is static in prin-
ciple. To create dynamically developing FM-sounds, comparable to the famous DX-series synthesizers, make use of the envelope generator of the modula­ting synthesizer channel (modulator). For example, by applying a short decay to the VCA with sustain set to zero, the carrier-modulation takes only place for the defined decay-time, specified for the modulator. The result is an e!ect comparable to a modulation­depth-parameter being modulated by an envelope. This way, you will achieve basses and lead sounds with pronounced, percussive attack-phases.

Filter Section (VCF)
The filter shapes the oscillator's output signals, either one of the available waveforms, the noise generator's output or an external audio signal. Certain frequencies will be suppressed, resulting in subtle to significant sound changes. Dynamic control of the filter will create progressive sound changes over time.
Each of the PerFourMer MKII's synthesizer channels o!ers a voltage-con­trolled resonance-capable low-pass-filter with a slope of 24dB per octave. This proven e!ective filter-type has already been used in legendary synthe­sizer-models developed by Bob Moog. A low-pass-filter allows frequencies of an audio signal to pass below a certain frequency (cuto! frequency) and suppresses all frequencies above.
The filter section has the following control elements:
Picture 2: The filter section
CUTOFF
This control sets the filter's cuto! frequency. This is the frequency from which the audio signal is manipulated (filtered). Frequencies above the cuto! will be attenuated with the filter’s slope. Setting the cuto! lower will result in a more mu"ed sound as more harmonics are suppressed.
Beside manual control of the cuto! frequency, this parameter can also be modulated and controlled by MIDI aftertouch or a corresponding MIDI control command. This function can be enabled/disabled using EDIT PARAMETER 3: AFTERTOUCH CUTOFF (VCF).

RESONANCE
Resonance is a feedback circuit within the filter that emphasizes the cut­o! frequency. Higher values can color the sound significantly, which is regularly used for resonant bass sounds in Acid-House and Techno. With values higher than 3 o' clock, the filter will start to self-oscillate, generating a sine wave with the cuto! frequency. This sound can even be played chromatically over a range of approx. three octaves, depend­ing on the TRACK switch's position. Here, it makes sense to disable any envelope modulation when playing the self-oscillating filter.
EG INT
This control sets the intensity of positive or negative modulation towards the cuto! frequency carried out by the ADSR envelope genera­tor. In its center-position, cuto!-modulation is turned o!. This control o!ers a center-catch.
LFO INT
specifies the intensity of cuto!-modulation by the LFO.
TRACK
The tracking switch sets the filter-tracking by the keyboard between 0% (o!), 50% (half) and 100% (on). With active tracking, the cuto! frequency increases with higher notes. This makes it possible to play deeply fil­tered sounds avoiding too gentle or thin results at higher octaves. Set­ting tracking to 100% will allow playing a self-oscillating filter chromati­cally within a certain range.
Filter-FM
The cuto!-frequencies of filter 2,3 and 4 can be modulated by the prior located synthesizer channel. Use the FM-controls 1 (
), 2
(
), 3 ( ) of synthesizer channels 2-4 to set the inten­sity for the frequency modulation. Set to center, modulation will be turned of. Turning the control to the right will increase the modulation intensity.

Page 14
Amplifier Section (VCA)
A voltage controlled amplifier (VCA) controls each synthesizer channel's output. This allows manual control over the output volume as well as dynamic volume progressions. Available modulation sources are the enve­lope generator and a fixed gate-envelope, the latter o!ering minimal attack- and release-phases to avoid unwanted clicks caused by disadvanta­geous phase cuts during sound reproduction.
Every synthesizer channel has the following control elements:
Picture 3: The VCA section
MODE
This switch sets the modulation source for the VCA, respectively sets the VCA to be opened permanently.
EG the ADSR envelope-generator modulates the VCA.
GATE ( ) a fixed organ-like envelope modulates the VCA.
ON the VCA is permanently on, no modulation.
The modulation intensity of the envelope generator can be controlled by MIDI-velocity. This function can be enabled/disabled using EDIT PARA­METER 4: VELOCITY, available for each synthesizer channel. To enable/ disable this function, carry out the following steps:
1. Press the EDIT-button.
2. Select parameter 4: VELOCIY using the SELECT/SEQ control.
3. Press TRIG to enable/disable velocity control for one or several syn-
thesizer channels. The corresponding red LED above each TRIG­button will display the respective velocity-status.
4. Exit edit-mode by pressing the EDIT-button.

PAN
The PAN control places the synthesizer channel's sound within the stereo image. At its center position, the PerFourMer MKII's left and right outputs are fed with the same level. This control o!ers a center catch.
Turning the control to the left shifts the level towards the left output until the synthesizer channel will only be audible from the left output. The same applies to the right output when turning the control clockwise.
NOTE The PAN control has no influence upon the individual
outputs (OUT/INSERT) of the synthesizer channels.
VOLUME
This control sets the output level for the corresponding synthesizer channel. It controls the level for the individual outputs (OUT/INSERT) and main outputs at the same time.

Modulation Generator (LFO)
The LFOs (Low Frequency Oscillators) allow creating cyclic repeating modu­lations of the oscillators and filter. The PerFourMer MKII's LFOs o!er a choice of functions that might not be seen at first glance: Its LFOs can be synchronized to each other and/or to a MIDI-clock. Also, they can be shifted against each other in phase.
The available control elements and parameters per LFO are:
Picture 4: The LFO
WAVE
This switch selects the LFO waveform. Choices are Sample & Hold (ran­dom), sine (
) descending saw tooth and rectangle ( ).
SPEED/PHASE
This control carries out two resp. three di!erent functions. Depending on the SYNC-switch position and/or the parameter setting for LFO MIDI CLOCK it controls
• the LFO's speed (frequency)
• the waveform's phase (not for synthesizer channel 1) or
• the MIDI-clock division
In unsynchronized mode, SPEED/PHASE controls the LFOs' speed/fre­quency within a range of 0.05Hz (approx. 20 seconds for a full cycle) to 250Hz.
Find details about LFO SYNC and LFO MIDI CLOCK SYNC in the next chapter.

Extended LFO Settings
Selecting between saw tooth and square waveforms
EDIT-Parameter 7 allows changing of the LFO's first waveform. Edit function LFO WAVE 1: SQUARE can select between square or descending saw tooth. This selection is available for each synthesizer channel.
The default setting as well as the reset default (see "RESET", page 30) for the first LFO-waveform is saw tooth. To switch to a square waveform, follow these steps:
1. Press the EDIT-button.
2. Select parameter 7: LFO WAVE 1: SQUARE using the SELECT/SEQ control.
3. Press TRIG to enable the square waveform for one or several synthe­sizer channels. The corresponding red LED above each TRIG-button will display the selected square waveforms. If the LED is not lit, the saw tooth is selected. Changes are audible immediately.
4. Exit edit-mode by pressing the EDIT-button.
LFO SYNC
The LFOs of synthesizer channels 2,3 and 4 can be synchronized in fre­quency to the prior module. To do so, switch SYNC for that synthesizer channel to the right LFO setting.
In this case, SPEED/PHASE will no longer control the LFO's speed but its waveform phase between 0° and 180°. Set fully to the left (0°), the synthe­sizer channel's LFO will run in phase with the prior located synthesizer channel's LFO. Set fully to the right (180°), both LFOs are out of phase and shifted by a half-cycle. Waveforms can still be selected independently for each synthesizer channel.
NOTE What sounds cumbersome in theory, is easy to
understand in practice. Simply try the sync-function. You will come across interesting complex rhythmic modulation patters very quickly.
With LFOs being synchronized by another LFO and the MIDI-clock, the LFO sync has priority. Here, SPEED/PHASE controls the waveform's phase, not the MIDI-clock divider.

Page 18
LFO > MIDI-clock-synchronization
All of the PerFourMer MKII's LFOs can be beat-synced to a MIDI-clock. MIDI­clock-synchronization can be enabled/disabled for each synthesizer channel independently using EDIT-parameter 8: LFO MIDI CLOCK SYNC.
To do so, follow these steps:
1. Press the EDIT-button.
2. Select parameter 8: LFO MIDI CLOCK SYNC using the SELECT/SEQ control.
3. Press TRIG to enable synchronization for one or several synthesizer channels. The corresponding red LED above each TRIG-button will dis­play the synchronization status. If the LED is lit, MIDI-sync is active.
4. Exit edit-mode by pressing the EDIT-button.
NOTE With MIDI-clock-synchronization being activated for
at least a single synthesizer channel, the green LED above the MIDI CH-button will start blinking to indi­cate clock-reception.
With MIDI-clock-synchronization being activated, SPEED/PHASE will control the division of the incoming clock-signal, i.e. it sets the LFO's speed within a grid, referenced to the MIDI-clock.
The outer labeling of the SPEED/PHASE control, indicates the eight available clock-divisions. The divisions equal the following note values (left to right):
• whole note
• 1/2 note
• 1/4 note
• 1/4 triplet
• 1/8 note
• 1/8 triplet
• 1/16 note
• 1/32 note

NOTE Changes from one scaling factor to another will take
place after a waveform cycle has been completed. Do not worry about a possible delay after switching at slower tempos - this is intended.
Internal MIDI-CLOCK
The PerFourMer MKII can also generate an internal clock to synchronize the LFOs. Its tempo can be adjusted using a TAP function.
To use the internal clock as LFO clock-reference, follow these steps:
1. Press the EDIT-button.
2. Select parameter 9: INTERNAL MIDI CLOCK using the SELECT/SEQ control.
3. Press TRIG to enable the internal clock-synchronization. The corre­sponding red LEDs above the TRIG-buttons will display the synchro­nization status. This is a global parameter, valid for all synthesizer channels.
4. Exit edit-mode by pressing the EDIT-button.
To change the tempo for the internal clock signal, follow these steps:
1. Press the EDIT-button.
2. Select parameter 10: MIDI CLOCK TEMPO using the SELECT/SEQ control.
3. Press any of the four TRIG buttons to TAP the tempo. The TRIG LEDs will be blinking with the current tempo. The new defined tempo will be set after four taps.
4. Exit edit-mode by pressing the EDIT-button.

Envelope Generator (ADSR)
The envelope generator (EG) generates a control voltage that can modulate the VCO and VCF as well as the VCA. The envelope generator is restarted by each incoming MIDI-note. (Exception: With LEGATO enabled, overlapping notes will not retrigger the envelope generator.)
The envelope contour is separated into four sections:
Picture 5: The Envelope Generator
ATTACK
adjusts the rising time from zero to maximum level. ATTACK starts when a MIDI note-on-command is received (or when using the TRIG button).
DECAY
adjusts the time from maximum level to a specific SUSTAIN level, while the MIDI note is still active. In case the MIDI-note is shorter than the decay-time, this phase will be aborted.
SUSTAIN
sets the envelope’s SUSTAIN level to follow attack and decay phases, while the MIDI note is still active. With SUSTAIN set to maximum, DECAY has no audible influence on the sound.
RELEASE
sets the time to zero level after a MIDI note-o! message has been received.

Legato
Each of the PerFourMer MKII's synthesizer channels allows its legato-mode to be enabled independently. In legato-mode, the envelope generator will not be restarted when note are played overlapping.
To enable/disable legato-mode, carry out the following steps:
1. Press the EDIT-button.
2. Select parameter 6: LEGATO using the SELECT/SEQ control.
3. Press one or several TRIG buttons to enable/disable legato-mode for one or several synthesizer channels. The corresponding red LEDs above the TRIG-buttons indicate enabled legato-modes for the channels.
4. Exit edit-mode by pressing the EDIT-button.
Connections of the Synthesizer Channels
Each of the PerFourMer MKII's synthesizer channels has two TRS-jacks that o!er two functions each. The function we consider the most frequently used is available on the tip contact, so that you may use common TS­cables.
The second function is available on the ring-contact and can be addressed with an insert-cable (Y-cable TRS to 2xTS) .
EXT IN / VCO OUT
This jack allows feeding an external audio-signal into the synthesizer­channel. This signal can be selected using the WAVE-selector switch. (See page 7).
The ring contact will output the pure oscillator signal, unaltered by the filter and VCA.
OUT / INSERT
This jack primarily servers as individual output for the corresponding synthesizer channel. However, using an insert-cable, this jack will pro­vide an insert for external e!ects such as a ring modulator or special filters.

Additional Control Elements
TRIG
The TRIG-button starts a single note or a sequence to play the Per­FourMer MKII's sounds without any keyboard or sequencer attached. Whether a single note or sequence is played, depends on the setting of the SELECT/SEQ control. Set to positions 1 to 4, single notes are played in di!erent octaves. Set to positions 5 to 16, di!erent sequences are played in varying complexity. The function to play notes and sequences is inactive when in edit-mode.
Single notes will be played and held as long as TRIG is held. Sequences will be started by pressing TRIG once and stopped by pressing TRIG again. A sequence will be stopped when the SELECT/SEQ control is used.
Combined synthesizer channels will always be triggered simultaneously but in regard to the selected PLAYMODE. For example, with synthesizer channels 1 and 2 being combined, hitting TRIG in channel 1 will also trigger channel 2.
When in MIDI- and EDIT-mode, the TRIG-buttons serve to assign MIDI­channels as well as parameter settings). (see "Combining Multiple Syn­thesizer Channels", page 25, see "Edit-Mode", page 29).
NOTE Use the internal sequences to make yourself familiar
with the di!erent playmodes (see "PLAYMODE", page
25). Changing from Mono1 to Mono2 can already result in surprising results.
TRIG LOCK / 440Hz
Use this switch to lock all TRIG-buttons. This will avoid unwanted trig­gering of sequences. As a secondary function, this button generates a continuous tuning reference.
Set this switch to the left (TRIG LOCK), to disable triggering of single notes and sequences. This is specifically useful in a live situation.
Set this switch to the right (440Hz), a digital generated tuning reference of 440Hz (equals MIDI notes A3 resp. A4) will be output.
MASTER TUNE
This control allows tuning the PerFourMer MKII within a range of ± one semitone. MASTER TUNE a!ects all four synthesizer channels.

MASTER VOLUME
This control sets the overall output volume. It a!ects the rear-outputs as well as the headphone output but it doesn't a!ect the individual synthe­sizer channel outputs.
SELECT/SEQ
During playmodes, SELECT/SEQ will select the single notes and sequences that will be triggered by the TRIG-buttons. Positions 1 to 4 will select single notes in di!erent octaves, positions 5 to 16 select di!erent sequences. When in MIDI- or edit-mode, the selector switch will set the MIDI-channel or an EDIT-parameter.
POWER
The POWER switch , located on the unit's rear, powers the PerFourMer MKII on and o!.
Connections
HEADPHONES

1V/OCTAVE CV INPUT/GATE INPUT (optional)
The PerFourMer MKII can optionally be equipped with CV/Gate-inputs. With this option installed, all four synthesizer channels can be addressed by ana­logue sequencers and CV/Gate-keyboards. Each synthesizer channel is accessed thru its individual CV/Gate jacks. Polyphony is only possible, if the controlling sequencers and keyboards support polyphonic note output. The playmodes (See page 25) are irrelevant when using CV/Gate-inputs because every synthesizer channel is directly addressed. Monophony or polyphony jst depends on the source that controls the PerFourMer MKII.
The CV-inputs control the pitch of the corresponding oscillator using the common volt per octave standard. Voltages up to 5V can be processed.
The gate-inputs trigger the PerFourMer MKII's ADSR envelope generators as well as the internal gate-envelopes. Here, voltages ranging from 2,5 to 10 volts with positive slope can be processed.
OUTPUT
These jacks carry the summed stereo output signal of all four Per­FourMer MKII's synthesizer channels.

Programming Section
The rightmost section of the PerFourMer MKII's panel serves to adjust the MIDI-channels, EDIT-parameters and PLAYMODES with the addition of global controls for MASTER TUNE and MASTER VOLUME.
Combining Multiple Synthesizer Channels
The four PerFourMer MKII's synthesizer channels can be combined in di!er­ent ways. Depending on the selected PLAYMODE, the synthesizer channels can be played monophic, duophonic or polyphonic.
To combine synthesizer channels, simply set them to identical MIDI­channels.
To do so, carry out the following steps:
1. Press the MIDI CH-button.
2. Select the MIDI-channel (1…16) using the SELECT/SEQ control.
3. Press one or several TRIG-buttons to assign the corresponding synthe­sizer channels to the selected MIDI-channel. The corresponding red LED above each TRIG-button will be lit.
4. Exit MIDI-mode by pressing the MIDI CH-button.
NOTE Steps 2 and 3 can be altered at any time until the
edits are confirmed by leaving the MIDI-mode.
PLAYMODE
PLAYMODE determines how combined synthesizer channels react to incom­ing MIDI-notes. The mode specifies if and how a synthesizer channel will react to a MIDI-note. The modes are selected using the PLAYMODE control. The following six modes are available:
MONO 1 (M1)
With this PLAYMODE enabled, all combined synthesizer channels are regarded as a singular monophonic synthesizer. All combined channels are played in unison.
In addition, Mono 1 is the standard-mode for all synthesizer channels not being combined. With channels 1, 2 and 3 being combined on MIDI­channel 10 and channel 4 reacting to MIDI-channel 11, channel 4 can be

played independently in Mono-1-mode, disregarding the selected PLAYMODE setting.
NOTE Mono-1-mode allows stacking of synthesizer chan-
nels. Here, you may use identical or di!erent settings for oscillators, filters and modulators. With wave­form, octave, filter etc. being adjusted roughly iden­tical, the PerFourMer MKII will react like a common synthesizer with multiple oscillators. However, it o!ers the advantage to spread channel across the stereo panorama and achieve a wide image without using a chorus e!ect.
With oscillators, filters and modulators being adjusted di!erently, you will create "stacked" sounds that are often used in today's music productions. A PerFourMer stack might look like this: Synthesizer channel 1 delivers a deep foundation using a heavily filtered saw tooth waveform, synthesizer channel 2 creates movement by using a square waveform, being modulated in pulse width as well as being fil­tered with high resonance. Synthesizer channels 3 and 4 form a sync-sound with short decay time that will add a pronounced attack to the sound. Feel free to experiment with stacks - you will come across endless sound variations.
MONO 2 (M2)
This PLAYMODE is monophonic, too. Here, the combined synthesizer channels are not addressed in parallel but one after another. The first MIDI­note will trigger e.g. channel 1, the next channel 2 and so on ...
NOTE Try out the same application as for Mono-1-mode.
When setting all four channels with identical settings but di!erent panning positions, the result will not sound chorus-like. Instead, the sound will be jumping in the stereo image rhythmically. This mode is well suited for fast sequences and arpeggios.

With oscillators, filters and modulators being set di!erently on all four channels and spread across the stereo image, a sequence can drastically change its sound when changing between Mono-1- and Mono-2-modes. Although, the same notes arrive at the input, the Mono-2-mode will give the impression of (up to) four new sequences, due to our ear separating the di!erent sounds from each other. Using an odd number of notes per beat will increase this e!ect further. Try to change between Mono-1- and Mono-2-modes frequently to discover new melodies!
POLY 1 (P1)
This PLAYMODE allows playing all combined synthesizer channels poly­phonically. Here, the PerFourMer MKII can be played with up to four-voice­polyphony.
With the PerFourMer MKII being configured as an e.g. four-voice polyphonic synthesizer, the fifth received MIDI-note will abort the oldest voice and replace it.
In Poly-1-mode, the PerFourMer MK II will store the order of all simultane­ously held notes. With a note being released, this voice will be used for another voice that is still active and held.
POLY 2 (P2)
The PLAYMODE is almost similar to Poly-1-mode with the di!erence that held notes are not stored.
NOTE With four voices, the polyphonic limit is reached
quite easily. To avoid or minimize unnatural inter­ruptions of notes, shorten the release times of all sounds to the lowest suitable values upfront.
DUO 1 (D1)
Both DUO-playmodes take an exceptional role. The PerFourMer MKII is split in two-voice-units (comparable to a synthesizer with two oscillators per voice). The first unit consists of synthesizer channels 1 and 2, the second unit of synthesizer channels 3 and 4. In di!erence to other playmodes, the synthesizer channels are constantly combined and played by the synthesizer channels 1's MIDI-channel.
Duo1-mode allows playing both units (voices) with monophonic alternating voice-fetching, similar to Mono-2-mode.

DUO 2 (D2)
This PLAYMODE allows the two voice units to be played duophonically.

Edit-Mode
The edit-mode allows adjusting di!erent settings for the individual synthe­sizer channels as well as global settings for the PerFourMer MKII. For easy handling, a list of all available parameters is printed to the unit's top-sur­face above the SELECT/SEQ control.
To change a parameter, perform the following steps:
1. Press the EDIT-button to enter edit-mode.
2. Use the SELECT/SEQ control to select the desired parameter (1..10).
3. Enable or disable the selected parameter using the synthesizer channel's TRIG-buttons. Parameters 1 to 8 are set individually per syn­thesizer channel while parameters 9 and 10 are global settings globally valid for the PerFourMer MKII.
4. Exit edit-mode by pressing the Edit-button.
The edit-mode allows adjustment of the following parameters:
1 - PITCH BENDER (VCO)
This parameter enables/disables pitch modulation using the pitch bender.
2 - MODULATION WHEEL (PWM)
This parameter enables/disables modulation of the oscillator's square waveform's pulse width through the modulation wheel.
3 - AFTER TOUCH (VCF)
This parameter enables/disables modulation of the filter's cuto! fre­quency through (channel) after touch data.
4 - VELOCITY (VCA EG)
This parameter enables/disables modulation of the VCA's envelope amount through incoming velocity data.
5 - AUTO GLIDE
This parameter enables/disables the auto-glide function. With audio­glide enabled, a glide (portamento) will only be performed with two adjacent notes being played overlapping.

6 - LEGATO
This parameter enables/disables the legato-mode. With legato enabled, the envelope will not be retriggered with adjacent notes played overlapping.
7 - LFO WAVE 1: SQUARE
This parameter enables/disables the alternative LFO square waveform shape. With this function enabled, a square waveform will replace the saw tooth waveform in the LFO.
8 - LFO MIDI CLOCK SYNC
This parameter enables/disables LFO-synchronization to MIDI-clock.
9 - INTERNAL MIDI CLOCK
This parameter enables/disables a replacement of the external MIDI­clock by an internal clock signal.
10 - MIDI CLOCK TEMPO (TAP)
This parameter allows setting the internal MIDI-clock-tempo using the TAP-button.
RESET
The PERfourMER MKII can be reset to factory settings. The Reset only a!ects the EDIT parameters and MIDI channel settings. For resetting the PER­fourMER MKII carry out the following steps:
1. Switch o! the PERfourMER MKII
2. Switch the unit on while pressing and holding the EDIT and MIDI CH button at the same time. Once the corresponding LEDs lights up, the reset has been made.
