  • Page 2: Overview

    Overview Specifications The Micromonsta is an 8-voice polyphonic desktop synthesizer. Small, powerful, great sound, usability and easy editing were key elements while designing the Micromonsta. It features: • 8 voices of polyphony • 2 oscillators, 1 sub oscillator, 1 multimode filter, 3 envelopes, 3 LFOs, 6 modulation slots, 3 scalers, 1 lag operator per voice •...
  • Page 3 Deep modulation matrix (with for example filter parameters, envelope or LFO speeds as destination) • A chorder module allowing the generation of 4-note chords within a key/scale • Internal FXs • 384 preset slots to store your sound creations Audiothingies Micromonsta user manual...

    6. Turn encoder 6 to navigate thru the patches. Press Load again to load selected patch, press Home to cancel and return to previously loaded sound. 7. Alternatively, you can push encoder 1 & 2 to navigate and load the previous or next patch Audiothingies Micromonsta user manual...
  • Page 7: Using The Micromonsta

    The LCD provides up to 6 parameters to edit. Use encoders 1-6 to change their corresponding parameter value. Some parameters can be reset to a default value when pushing the corresponding encoder (all bipolar parameters for example). Audiothingies Micromonsta user manual...

    You can navigate presets from this screen by pressing encoder buttons 1 and 2. Quite useful in a live situation. NOTE: When in this mode, LEDs 2 to 9 will show the activity of voices 1 to 8. Audiothingies Micromonsta user manual...

    A sinus oscillator that turns into a basic FM operator with the shape control A triangle oscillator into a foldback digital distortion. Shape controls the gain. When shape is set to 127, the oscillator will produce a triangle wave with its pitch one octave and a fifth higher. Audiothingies Micromonsta user manual...

    The shape parameter controls the pitch of the slave oscillator. Same as sws but with a square slave oscillator rz1, rz2 and rz3 Those are phase distortion algorithms from the Casio CZ series. They all simulate a filter sweep with the shape parameter. Audiothingies Micromonsta user manual...

    Each wavetable contains 33 slices. The shape parameter controls the position of the reading index and will interpolate between the slices. w16 to w30 User wavetables. By default, these wavetables produce no sound… until you upload your own :) Audiothingies Micromonsta user manual...

    These filters are all working in the same way: • When the value is negative, it acts as a 6dB lowpass filter • When the value is positive, it acts as a 6dB hipass filter • When set to 0, it has no effect Audiothingies Micromonsta user manual...

    You can also set the rmd level, which is the level of the output of osc1 and osc2 thru a ring modulator. When adjusting patch volume, always compare the patch level compared to one of the factory presets, pushing this parameter too hard (especially for polyphonic patches) may end with unwanted nasty distortion.

    Note: This phase relationship will be true unless you modulate the LFO speed in the modulation matrix. If you applied modulation and removed it, you can resync the LFOs either by: • sending a MIDI start command • turning the phase parameter encoders Audiothingies Micromonsta user manual...
  • Page 21: The 8-Step Lfo Sequence | Step

    Remember that, to be active, one (or several) LFO(s) shape must be set to ‘stp’ for the sequence to have an effect. And you also need to set a modulation destination amount different from 0 for this LFO in the matrix too to hear the effect of the sequence on the sound. Audiothingies Micromonsta user manual...
  • Page 22: The Modulation Matrix | Matrix

    Some sources are bipolar (lfo’s, rnd), other unipolar (envelopes, velocity, …). Modulation amount is bipolar, meaning you can reverse the modulation source amount by setting a negative number. On lfo’s, this reverse the phase for example. Audiothingies Micromonsta user manual...
  • Page 23: Before Using The Matrix

    This means that if you want to modulate the filter cutoff by a LFO, the first best candidate is LFO2, as it is already routed to the filter cutoff, it does not “eat” a modulation slot. Some more are available in the Voice and Global pages (glide, pitch bend, detune). Audiothingies Micromonsta user manual...
  • Page 24: Scalers & Lag | Scaler

    Filter page, that is +40 But when modulation wheel is set to 0, LFO2 WILL have an effect on Filter cutoff, the more the scaler amount, the less the effect, here at 50% of +40, which is +20. Audiothingies Micromonsta user manual...
  • Page 25 In fact, the scaler amount allows you to set a minimum value for the scaler destination when the source is set to its minimum value. Sounds scary? Try them by yourself, they’re easier than you may think and they’re the ideal way to add velocity or aftertouch expression to your patches. Audiothingies Micromonsta user manual...

    Tip 2: if you set the voice mode to m2 (legato mode), a step set to _ or / will slide to the next step if it is different from a rest and if glide is different than 0. Great for 303-ish mono sequences. Audiothingies Micromonsta user manual...
