The MicroFreak has 22 distinct sound engines (as of the 5.0 update), which are: • Basic Waves – a standard synth voice using traditional waveforms • Super Wave – a group of detuned waves (like a supersaw), • Harmonic – a form of additive synthesis where you set volumes of frequencies individually, • Karplus-Strong – a physical modelling system to replicate string sounds, • Wavetable – a method of synthesis where the waveform transitions through a table of different waveforms, • Noise – various types of noise and static. • Virtual Analogue – a standard subtractive synth voice, • Waveshaper – a triangle wave that is repeatedly wavefolded, • Frequency Modulation (two operators) – a method of synthesis where a wave modulates the frequency of another wave, • Formant – a form of granular synthesis, • Chords – an engine that plays groups of notes paraphonically, • Speech – a vocal synthesizer, • Modal – a physical modelling engine that replicates the sound of hollow objects, • Bass – another waveshaping algorithm specifically for basslines, • Harm – a mixture of waveshaping and additive synthesis, • SawX – a supersaw being phase modulated, • Vocoder – a voice transformer similar to a talkbox, • User Wavetable – an engine to use your own wavetables, • Sample – an engine that plays back loaded samples, • Scan Grain – a granular synthesizer that scans through a whole sample, • Cloud Grain – a granular synthesizer that creates overlapping grains from a sample. • Hit Grain – a granular synthesizer that creates percussive sounds from a sample. Of those, 12 are made by Arturia (Basic Waves, Super Wave, Harmonic, Karplus-Strong and Wavetable, Noise, Vocoder, User Wavetable, Sample, Scan Grain, Cloud Grain, and Hit Grain), 7 are made by Mutable Instruments (Virtual Analogue, Waveshaper, Two operator FM, Formant, Chords, Speech and Modal) from their "Plaits" eurorack module, and the remaining 3 are made by Noise Engineering.

Arturia made available user installable firmware updates for the MicroFreak with additional features and improvements in the years after the original release. • 1.0 – MicroFreak released with this firmware • 2.0 – Added noise engine, chord mode and scale quantisation • 2.1.3 – Added vocoder engine. Vocoder edition released with this firmware. • 3.0 – Added noise engineering oscillators, unison mode and more preset slots • 4.0 – Added user wavetable engine and 64 more preset slots • 5.0 – Added sample and grain engines, 128 more preset slots, and a sample and hold mode for keybed modulation. The Stellar edition released with this firmware.

It received a limited edition white Vocoder design in 2020. • Illustration — MicroFreak Vocoder (top left in white) is located above a MatrixBrute (bottom left)
