User Manual

1. CONNECTIONS
Panel Release latch - Push, then use the hinged prop inside the case to set the control panel
at the most convenient angle. You can also leave the panel flat.
1. Master Out - 1/4" unbalanced +4dBu stereo line-level outputs, intended to go to an amp and
speakers, or to an audio interface or mixer. For mono use the left channel only.
2. Insert Send/Return - +4dBu 1/4" TRS jack for sending the output of the synth (mono) to
an external processor and back in. This goes before the Master Out in the signal path. It
requires an insert cable, wired: Tip = Send, Ring = Return, Sleeve = Ground.
3. CV Ins/Outs - 3.5mm control voltage outputs and inputs for being controlled/controlling
by modular synthesizers. 12 parameters are available (VCA, LFO 1 Amount, Ladder Filter
Cutoff, Steiner Filter Cutoff, VCO 2 Metal, Pulse Width, Ultra, Pitch; VCO 1 Metal, Pulse Width,
Ultra, Pitch). The CV inputs are tolerant to +/-15V
4. Input - External input. Run external instruments through the MatrixBrute's synthesis
engine.
5. Input Type (Inst/Line) - For external instrument, use Instrument level for Hi-Z sources like
an electric guitar or bass; use Line level for sources such as another electronic instrument,
mixer output. This is an unbalanced input. Line = 68kΩ. Instrument = 1.1MegΩ
6. Gain - Level control for external instrument input, used in conjunction with the Gate (#7).
Line Gain = 0 -> 20dB. Instrument Gain = 0 -> 40dB
7. Audio Gate (Off/On) - A gate extractor that allows you to use external audio signals, like
a guitar, to trigger the envelope generators. The Gain control (#6) adjusts the level of the
instrument relative to this threshold.
8. Gate In/Out - Receives/sends a voltage trigger, usually to/from another analog
synthesizer. Use it to trigger the MatrixBrute from another source, such as an analog drum
machine.
9. Sync In/Out - This allows you to syncronize the Matrixbrute with devices that support the
DIN 24 sync standard.
10. Expression 1, 2; Sustain - Pedal inputs. Expression 1 and 2 are for continuously variable
expression pedals (sometimes called volume pedals), Sustain is for a momentary on/off
pedal (i.e. a sustain pedal).
Some manufacturers reverse the polarity of their pedals; download the MIDI Control Center
software from www.arturia.com to correct the polarity of any of them. These pedals are
converted to MIDI, so they appear in the MIDI Out datastream. Expression pedal wiring is
Tip = pot center tap; Ring = 3.3V; Sleeve = Gnd
11. Memory Protection On/Off - When off, prevents the MatrixBrute's patch Preset and
sequencer Pattern memories from being overwritten.
12. MIDI In/Out/Thru - Standard 5-pin DIN jacks. Connect to MIDI interfaces and other
equipment.
