Arturia - MicroFreak Synthesizer Keyboard - 25-Key Hybrid Synth with PCB Keyboard, Wavetable & Digital Oscillators, Analog Filters Blue
Arturia
6% OffFree Shipping
Why we love it
  • Innovative hybrid synth capabilities.
  • Unique pressure-sensitive keyboard.
  • Extensive connectivity options.
Main Highlights
  • EXPERIMENTAL HYBRID SYNTH: MicroFreak packs so much into such a compact instrument, you'll wonder how we did it. From physical modeling to wavetable synthesis, it features 17 awesome paraphonic oscillator modes, including 7 bespoke Arturia engines, 7 modes from Mutable Instruments, and 3 modes designed with Noise Engineering. Its digital engines are combined with a lush-sounding resonant analog filter for true hybrid sound design.
  • UNIQUE KEYBOARD: It isn’t really even a keyboard, it’s a super-flat PCB with no moving parts. The 25-key printed circuit board not only tracks the notes you play with lightning-speed, but can also detect pressure or aftertouch on each note individually.
  • INNOVATIVE FEATURES: Record up to four automations, edit notes per step, or use the innovative Spice and Dice sequencer functions to find happy accidents. Add randomization to create evolving, original patterns, and virtually rewire and reconfigure its signal chain and controls with the 5x7 modulation matrix, with user-assignable destinations for totally unique sounds.
  • MULTIPLE MODES: Easily switched and directly controlled with the 4 dedicated knobs in the Digital Oscillator section, MicroFreak has been constantly evolving. It now contains 17 oscillator types, covering a multitude of timbral flavors from sweet to savage: Vocoder, Noise, Superwave, Harmo, Karplus Str., Wavetable, BasicWaves, with many more.
  • AMAZING CONNECTIVITY: It features CV outputs, letting you send pitch, gate, and pressure signals to any outboard or modular synth that’s CV/Gate compatible. You can also hook it up to your DAW via USB, or use the included MIDI break-out cables.
