Introduction

Overview

MicroMonsta 2 is a dual polyphonic synthesizer featuring :

  • 2 x 6 voices of polyphony
  • 3 oscillators, 1 multimode filter, 3 envelopes, 3 LFOs, 10 modulation slots and 2 operators per voice (lag and mult)
  • 12 « analog » oscillator types + 4 FM-able oscillators for OSC1
  • 12 « analog » oscillator types + 8 multisampled wavetables for OSC2 and OSC3 (FM source)
  • 8 filter types with FM
  • Per voice and per oscillator detuning options for analog  character
  • Deep modulation matrix
  • Delay + reverb

MicroMonsta 2 can be used in 3 different ways :

  • Monotimbral : As a 12-voice polyphonic synthesizer
  • Bitimbral : As 2 different 6-voice polyphonic synthesizer (on 2 different MIDI channels)
  • In combi mode, where you can stack, split or mult the 2 programs

You get 300 programs slots + 100 combi slots to save your sound creations.

The 100 combi slots also save their 2 sound programs in separate program slots (so you get 300 + 2 x 100 = 500 program slots in total).

New in firmware v2.1
  • Deeper FM
  • Filter character
  • 1 additional mult operator
  • Chorus and EQ per program
  • Delay tempo sync
  • Arp pattern (16 steps)
  • MPE mode
  • And lots of other small things that will be covered in this manual
Front panel

Front panel

You get :

  • 2×16 characters LCD screen, white on black
  • 3 assignable pots for live edits
  • 1 volume pot
  • 4 edit encoders
  • 9 pushbuttons with their associated LEDs
  • 2 No/Yes pushbuttons
Rear Panel

On the rear panel :

  • USB B port for power and USB MIDI
  • 3.5mm stereo jack MIDI input (MIDI A Standard)
  • 3.5mm stereo output (line out / headphones out)
Power considerations

MicroMonsta 2 is powered via its USB B port. Several options are thus available :

  • It can be powered with any USB power supply capable of outputting 500mA @ 5V DC (any modern USB power supply should meet these specifications, and you probably have half a dozen of those in your drawers)

  • It can be powered via a USB port on a computer
    A drawback of this method is that a ground loop can be created which can cause hum in the audio output. To avoid such a ground loop :

    • Use a USB isolator between the computer and MicroMonsta 2
    • Use a stereo line level DI with ground lift switch between MicroMonsta 2 and the mixer
  • It can be powered with a USB power bank for extra mobile use

Using MicroMonsta 2

Currently edited program

MicroMonsta 2 can play up to 2 sounds at the same time – loaded into Programs A and B. Only 1 Program can be edited at a time, and it can be selected by pressing its corresponding A or B button (B button will be disabled in monotimbral mode).

Currently edited program always has its LED lit as an all time indication.

Synthesis parameters are mapped across different sections accessed by pressing a button on the front panel.

When a section has several pages, you access them by successively pressing the same button several times. When you are on the last page, it returns to the first one.

For example, pressing OSC several times will make you travel the following pages: OSC1 > OSC2 > OSC3 > OSC1 > OSC2 etc.

Some sections (the ones labelled in orange) are accessed by long pressing the corresponding button. For example long-pressing OSC will take you to the Mixer page.

Some pages can have sub-pages accessed by turning encoder 1 (all the  orange labelled sections forexample)

All this may seem complicated while reading, it is however quite fluent once you have the gear in front of you.

Editing parameters

Encoders

The LCD screen provides up to 4 parameters to edit at the same time. Use encoders 1-4 to change their corresponding parameter value.

Knobs

The 3 knobs F, Q and M are factory mapped to (respectively) filter frequency, resonance and mod knob (accessible in the mod matrix).

They can be remapped either globally or per preset to any synthesis parameter.

Modes

MicroMonsta 2 can be globally set to 3 different modes that can be changed anytime in SYSTEM menu. They affect the number of available sounds MicroMonsta 2 can play at the same time and the way it responds to incoming MIDI signals

Monotimbral

In monotimbral mode, you can play 1 sound at the same time, with 12 voice polyphony. Sending a MIDI bank change / program change on MicroMonsta 2 MIDI channel will change the currently selected program.

Bitimbral

In bitimbral mode, you can play 2 sounds at the same time on 2 different MIDI channels, each sound

having 6 voices polyphony.
Program A is accessed on main MIDI channel (the one set in SYSTEM menu), while Program B is accessed on main MIDI channel + 1.

By sending a MIDI bank change / program change on one of those 2 MIDI channels, you can change the preset loaded in Program A or B.

This mode is ideal when used with an external sequencer.

Combi

In combi mode, you can combine up to 2 different programs in 4 different ways

  • only A : same as monotimbral mode
  • stack AB : 2 sounds played at the same time on the same MIDI channel
  • split AB : 2 sounds at the same time on the same MIDI channel, but the keyboard is split
  • mult AB : 2 sounds at the same time on 2 different MIDI channels (same as bitimbral mode)

By sending a MIDI program change in combi mode, you load an entire combi containing the combi parameters AND both programs A and B.

In combi mode, it is not possible to change Program A or B independantly by sending a program change message.

Presets

Synthesis overview

Here is a very basic overview of the synthesis engine of MicroMonsta 2. Not shown : all the LFOs, ENV3, the modulation matrix and all the other stuff that can really render this drawing really really complex.

As you can see, the base stuff is pretty standard substractive synthesis.
Synthesis overview

Editing a sound

Quick edit

Quick edit menu is accessed by pressing A or B (if available).
This is the menu you are landing when powering your MicroMonsta 2.
Quick edit

Here you see the program name and number, and you have direct access to 4 shortcuts to 4 different synthesis parameters.

By default, these are set to ENV attack time, ENV1 release time, delay level and reverb level. These assignments can be changed either at program level (see PROGRAM parameters section) or globally in SYSTEM menu (see SYSTEM parameters section).

OSC Oscillators

MicroMonsta 2 features 3 independant oscillators per voice, they all have the same parameter set, but they cannot access the same algorithms :
Editing a sound

  1. Oscillator algorithm
  2. shp : oscillator shape
  3. coa : coarse tuning
  4. fin : fine tuning

Available oscillators algorithms

  • Sine : clean sine waveform (no shape parameter)
  • SinF : fully rectified sine waveform (no shape parameter)
  • SinH : half rectified sine waveform (no shape parameter)
  • TrPs : Triangle to Pulse waveform
  • TrSw : Triangle to Saw waveform
  • TrSq : Triangle to Square waveform
  • Saw : Sawtooth waveform
  • Sup1 : Supersaw 1 (3 x sawtooths)
  • Sup2 : Supersaw 2 – alternate version
  • SwHs : Hardsync’d sawtooth
  • Squr : Square to Pulse waveform
  • SqHs : Hardsync’d square

FM-able algorithms (exclusive to OSC 1)

  • FmSi : Sine waveform
  • FmTr : Triangle waveform
  • FmSw : Sawtooth waveform

For all these waveforms, the shape (shp) parameter controls the amount of FM from OSC3.

Wavetables (exclusive to OSC2 and OSC3)

8 wavetables, each containing 64 slices, are available to OSC2 and OSC3, they are labelled Wt01 to Wt08.

For all these wavetables, the shape (shp) parameter controls the position of the virtual scanning head within the wavetable (in other words, it controls the slice playing).

Main waveforms graphical representation
Main waveforms

MIXER

The traditional source mixer menu, allowing to balance each oscillator and the white noise source level. The output of the mixer is sent to the filter.
MIXER

  1. Oscillator 1 volume
  2. Oscillator 2 volume
  3. Oscillator 3 volume
  4. White noise volume
FILTER

MicroMonsta 2 has 1 multimode filter per voice, its parameters are spread on 2 different pages :
FILTER Parameter

  1. Filter type

  2. Filter cutoff frequency

  3. Filter resonance

  4. Filter enveloppe 2 amount
    FILTER

  5. Filter character (soft, mild, hard, mean)
    Affects resonance. Original MicroMonsta had only soft mode. Default for MicroMonsta 2 : mean

  6. N/A

  7. Keyboard tracking (0 – 100)

  8. Filter FM amount (from OSC3)

Filter types

8 filter types are available :

  • LP1, LP2, LP3, LP4 : 1, 2, 3, 4-pole lowpass filter
  • HP2 : 2-pole hipass filter
  • BP2 : 2-pole bandpass filter
  • Not : Notch filter
  • Pha : Phaser filter

The lowpass filters do not lose bass frequencies when the resonance is increased (full resonance compensation).

DRIVE

The drive parameter is applied at the voice level, and is very useful to add dirt to the sound.

The mix parameter is applied post-fx (think of it as a master volume for the selected program). It is particularily useful to balance the output level of the program. Be carefull as setting it too high can produce unwanted distortion on the output.
Drive Instructions

  1. N/A
  2. N/A
  3. drv : Drive level
  4. mix : Program output level
ENV | Envelope

3 envelopes are available per voice, ENV1 directly controls the VCA, ENV2 controls the filter frequency and ENV3 is free.

All 3 envelopes are assignabled in the modulation matrix.
Envelope Instruction

They all have the same parameters:

  1. Envelope attack time (1ms – 30s)
  2. Envelope decay time (1ms – 30s)
  3. Envelope sustain level
  4. Envelope release time (1ms – 30s)
LFO | Low frequency oscillator

3 LFOs are available per voice.
They can be assigned in the modulation matrix.
Low frequency oscillator

They all have the same parameter set :

  1. N/A

  2. wav : LFO waveform

  3. spd : LFO speed
    LFO can be synchronized to the tempo by setting its speed above 127 (different synchorized values are available)
    If you need a speed that is not reachable with the parameter, use the matrix to offset LFO speed

  4. mod : LFO mode (see below)

Bipolar LFO waveforms

They start from 0, go up first, then down, oscillating between -0.5 and 0.5 and return to 0 at the end of their cycle.

They are best used to modulate a parameter around its current value.
Their polarity can be reversed in the matrix by setting a negative modulation amount.
LFO waveforms

Not shown:

  • s&h : sample & hold, a new value is calculated at each cycle
  • rnd : like s&h, but continuously random waveform

Unipolar LFO waveforms

These oscillate between 0 and 1
Unipolar LFO waveforms
Unipolar LFO waveforms

Not shown:

  • s&h : sample & hold, a new value is calculated at each cycle, between 0 and 1
  • rnd : like s&h, but continuously random waveform

LFO modes

  • vce : per voice mode, the LFO is restarted at each key press
  • one : same as vce, but the LFO stops after one cycle
  • key : global mode (1 LFO for all voices within the program), the LFO is restarted at each key press
  • fre : same as key, but free-running
MATRIX | Modulation matrix + Operators (lag + mult)

Pressing the MATRIX button will alternate between the Mod matrix and the Lag operator view

Modulation matrix

The modulation matrix allows you to apply a modulation source (an enveloppe or a LFO for example) to a selection of synthesis parameters.
There are 10 modulation matrix slots per program.
Modulation matrix

In mod matrix view, the encoders control the following parameters :

  1. Mod matrix slot selection (1 to 10)
  2. Mod matrix destination
  3. Mod matrix source
  4. Mod matrix amount

NOTE : Mod matrix amount is a bipolar value (-99 to +99) and its behavior in not linear (by design). It allows subtle modulations in lower values, so if you want a drastic change, do not be afraid to push the value:)

Lag operator

Lag operator allow you to « slow » a modulation source, and use the result as a modulation source in the modulation matrix.

For example, « Lagging » a square LFO will round its edges for a less abrupt changes between states.
Lag operator

In Lag operator view, you control :

  1. OP selector
  2. N/A
  3. Lag source
  4. Lag level

Mult operator

Mult operator multiplies 2 modulation sources and allows you to use the result as a modulation source in the matrix.
Mult operator

Controls are :

  1. OP selector
  2. N/A
  3. A mod source
  4. B mod source

    Voice parameters

  5. Voice page selector

  6. Pan spread mode (dif, bal)
    When unison is disabled, dif(fused) will spread the voices in the stereo field, each one having a different pan position, while bal(anced) will send them either on the left or on the right.
    When unison is enabled, dif will pan each voice in the unison differently and will make the final stereo image different for each polyphonic note, while bal will try to center the stereo image of each note (but each voice of the unison has its own pan position).

  7. Pan spread amount
    When set to 0, all voices are pan to center position. Increasing this amount will shift each voice according to the pan spread mode.

Microtuning

Micromonsta 2 can be retuned globally by sending a Bulk Tuning Dump via MIDI. Bulk Tuning Dump format A bulk tuning dump has the following format: F0 7E 08 01 tt [xx yy zz] … chksum F7, where:

  • is 0x00 or 0x7F (all devices)
  • tt is tuning program number (not used, set to 0x00)
  • is 16 ASCII characters (not used, set it to “NotUsedButNeeded” for example)
  • [xx yy zz] is the frequency data for one note (repeated 128 times)
  • chksum is the calculated checksum (not used)

Limitations

Bulk Tuning Dumps are global, all the patches will be affected.

They are not stored in Micromonsta 2 memory, this means that each time you power it off, it will lose your custom tuning, and you will need to send it again for the working session.

MPE

MPE stands for Multidimensional polyphonic Expression.

This protocol is using 1 MIDI channel for common messages (like sending CC to control a synth parameter) and multiple MIDI channels for voice messages (usually 1 channel per voice), enabling the use of per voice pitch bend, aftertouch and other messages.

MPE compatible controllers are made by Roger Linn (the Linnstrument), Roli (Seaboard Block/Rise) and others…

When set to MPE mode (see System settings page 3), the Micromonsta will need a controller set to the following settings for best use:

  Monotimbral mode Bitimbral Mode Pgm A Bitimbral Mode Pgm B
Common channel 1 1 16
Notes MIDI channels 2 to 16 2 to 8 9 to 15
X-Axis Your controller needs to match MicroMonsta 2’s pitch bend range

setting
Y-Axis| CC74 (hardwired to filter cutoff) or CC1 (modulation wheel)
Z-Axis| Aftertouch

Factory reset

To Factory reset your MicroMonsta 2, hold A + B + Yes at startup.
