Arturia MicroFreak 25-Key Hybrid Synthesizer w/ OG PSU

We strive for accuracy, but errors can occur. Please verify details or contact us with questions.

• 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.
