For sale: Arturia MicroFreak 25-key hybrid synthesizer in very good condition with original power supply. This is a great opportunity to explore Arturia's hybrid synthesis model without breaking the bank.
Details below:
Fully tested and in perfect working order.
Updated to the latest OS with factory sample packs loaded.
Includes the original Arturia power supply.
This unit is nice and clean overall, but not perfect. There are a few spots of minor discoloration in the finish (see photos 11-12). Please examine all photos carefully, as we have done our best to document the condition.
Note: This unit uses Type-B MIDI TRS adapters. Be sure to purchase Type-B adapters if you intend to use DIN MIDI instead of USB MIDI.
The Arturia MicroFreak is a compact hybrid synthesizer that combines digital oscillator engines, sample playback, wavetable-style textures, granular-style engines, and an analog filter with a capacitive 25-key keyboard, built-in sequencing, arpeggiation, and a flexible modulation matrix. It is a great little synth for experimental sound design, quick sketches, unusual textures, sample-based sounds, and hands-on hybrid synthesis without taking up much space.
Sale includes the synth and original power supply.

- Synthesis Type: Hybrid synthesizer combining digital oscillators with an analog filter, featuring wavetable, physical modeling, virtual analog, sample playback, granular processing, and vocoder modes for a versatile sonic palette.
- Polyphony: Paraphonic up to 4 voices (single filter and VCA shared); monophonic by default with independent envelopes and polyphonic pressure modulation per voice.
- Oscillators: 1 digital oscillator with 22 modes (as of OS 5):
- Modes: Basic Waves, Superwave, Harmonic, Karplus-Strong, Wavetable, Noise, Vocoder, User Wavetable, Sample, Scan Grain, Cloud Grain, Hit Grain (Arturia); Virtual Analog, Waveshaper, Two-Operator FM, Formant, Chords, Speech, Modal (Mutable Instruments); 3 modes from Noise Engineering (Bass, Sawx, Harm).
- Controls: Type (selects engine), Wave, Timbre, Shape knobs for real-time parameter tweaking.
- Sample Import: OS 5 enables user sample import via MIDI Control Center for looping and granular manipulation.
- Granular Engines: Scan Grain, Cloud Grain, Hit Grain for percussive and textured timbres.
- Filters: 1 analog state-variable filter, 12dB/octave (2-pole), inspired by Oberheim SEM:
- Modes: Lowpass, Bandpass, Highpass with resonance, capable of self-oscillation.
- Modulation: Filter cutoff can be modulated by keyboard pressure, sequencer, or modulation matrix for dynamic sound shaping.
- Effects: No onboard effects processor; external effects recommended for reverb, delay, or distortion.
- Modulation:
- Modulation Matrix: 5x7 matrix with 5 sources (LFO, ADSR envelope, cycling envelope, keyboard pressure, velocity) and 7 destinations (oscillator parameters, filter cutoff, etc.), including 3 user-assignable destinations.
- LFO: 1 LFO with 6 waveforms (sine, sawtooth, square, triangle, random, slew random) and sync capability.
- Envelopes: 1 ADSR envelope (controls VCA or filter); 1 cycling envelope (functions as LFO or one-shot envelope with variable rise/fall times).
- Polyphonic Aftertouch: Capacitive keybed provides per-note pressure modulation for expressive control.
- Memory: 512 preset slots (320 factory, 192 user); patches manageable via Arturia MIDI Control Center.
- Arpeggiator: Polyphonic arpeggiator with 4 modes (Up, Order, Random, Pattern), up to 4-octave range, and Spice/Dice randomizers for creative variation.
- Sequencer: 64-step sequencer with 2 patterns per preset, 4 automation tracks per pattern, and Spice/Dice functions for randomization of note duration and parameters.
- Connectivity:
- Audio Output: 1 mono 3.5mm jack; 1 TRRS headphone output (also serves as vocoder mic input).
- MIDI: 3.5mm TRS MIDI In/Out (includes two 3.5mm to 5-pin DIN adapters); USB-MIDI for DAW integration.
- CV/Gate: 3.5mm outputs for pitch, gate, and pressure to control modular synths or Eurorack.
- Clock: 3.5mm Clock In/Out for syncing with external gear (TRS for clock/start, TS for clock only).
- USB: Type-B for MIDI, preset management, and optional power (5V DC).
- Physical Design: Compact desktop synthesizer with a sleek black finish (Stellar edition features space-age graphics); robust plastic chassis; 25-key capacitive touchplate keyboard with polyphonic aftertouch.
- Additional Features:
- Vocoder Mode: 16-band vocoder with 16 presets, compatible with optional gooseneck TRRS microphone for vocal processing and formant sequences.
- Scale Quantize: Locks notes to a specific scale for simplified composition.
- Chord Mode: Plays predefined chords with a single key press, ideal for trance or ambient styles.
- Firmware Updates: OS 5 adds sample import, 3 granular engines, sample-and-hold keybed modulation, and 128 additional preset slots.
- Touch Strip: Capacitive strip for pitch bends, modulation, or controlling Spice/Dice depth.
- Limitations: No onboard effects; single analog filter shared across voices in paraphonic mode; capacitive touch keyboard may not suit traditional players; mono audio output; some menu diving required for utility settings.
