    On MicroFreak

    “A modern classic at the time of its presentation, Arturia MicroFreak is a very difficult contender to beat in its price range. If you take into account its sound versatility and its ability to create breakthrough sequences, and all for a price less than € 300, you have to rub your eyes to believe what you're seeing - and listening... Its variety of sound generators and the flexibility of modulation are incredible for a synth of this price. -Arturia wanted to raise very high what a low-priced instrument has to offer The Arturia MicroFreak digital synthesizer represents the intention of those of Grenoble to capture the imagination and the desire of the beginner users of synthesizers, but also of those more demanding and creatively advanced.”
