News of an Arturia polysynth wasn’t a total surprise. Since the early-’10s, the French brand’s lineup of synths has grown to encompass budget analogue (MicroBrute), semi modular (MiniBrute 2/2S), a behemoth monosynth (MatrixBrute) and eccentric digital synthesis (MicroFreak). Their 20th anniversary seemed an obvious moment to unveil a new flagship instrument.

You may spot the similarities between the PolyBrute and MatrixBrute; most obviously in the inclusion of a similar button matrix, but also in the general architecture. Although it wouldn’t really be accurate to describe this synth simply as a polyphonic MatrixBrute, it’s not entirely baseless. Like the MatrixBrute, the PolyBrute is a digitally-controlled analogue synth combining multiple VCOs and VCFs with a powerful modulation matrix, sequencer and arpeggiator. The MatrixBrute’s distinctive dual filter setup is carried across here too, which pairs Steiner Parker and Ladder Filter designs that can be positioned in series or parallel.
