In its standard Morph mode, rather than simply switching or fading between two static sounds, the synth will smoothly transition each affected parameter from its A state to its B state. With a few exceptions, every synth parameter can be assigned separate A and B states and, rather than simply switching between the two, the PolyBrute uses a rotary to allow gradual blends of the two setups. It is multitimbral though, with the ability to set up two distinct sounds at once (labelled A and B). The PolyBrute is a six-voice instrument so it’s far from the most polyphonic synth in its price range. While modulation routings themselves are fixed for both A and B states of each patch, the depth of each can be morphed so, combined with the ability to assign up to 64 modulation patches for each sound, you can morph between two entirely different modulation setups within a single patch. Functionally, it fulfils the same roles, acting as a handy preset browser, a controller for the multi-lane sequencer and, most usefully, a digital patchbay for assigning and editing modulation routings.įor the PolyBrute, 12 modulation sources are fixed down the left-hand side of the grid, and up to 32 modulation routings can be freely assigned across four banks along the top row.Įditing modulation patches is a simple case of holding the relative grid button and twisting a knob to apply the required depth. The MatrixBrute’s titular button matrix makes a return here, in a more compact, 12x8 form.

Unlike on the MatrixBrute, there’s no CV connectivity here though, and no audio input either, so there’s no way to run external sounds through those dual filters or the effects. Here we get master stereo outputs plus a headphone output, along with MIDI in, out and through, USB MIDI, analogue pulse sync in and out and three pedal inputs (sustain and two expression).

There are a few I/O differences between the Matrix and PolyBrute too.

These modulation sources can be applied to almost any synth parameter using the matrix, and while the Morphee and ribbon controller don’t entirely negate the presence of traditional pitch and mod wheel – also included here – they’re excellent additions that are likely to have even seasoned synth players expressing themselves in new ways.
