Performance Control Matrix
The Performance Control Matrix lets you edit certain parameters of the synthesizer in real-time. This provides
you with expressive control of the synthesizer during performance beyond simply playing preset synth
sounds.
Matrix Row Select Buttons and LEDs
Use the Matrix Row Select buttons to select the next or previous Matrix row (1–6) as printed to the left of the
Matrix Controller Knobs and Button. The selected Matrix row determines what synth parameters are con-
trolled by the Matrix Controller knobs (1–4) and the Matrix Control button. The selected row is indicated by
which of the 6 LEDs below the Matrix Row is lit.
Matrix Controller Knobs 1–4
Each Matrix Controller knob affects specific synthesizer parameters based on the currently selected Matrix
Row. The Matrix Controller knobs also send out continuous controller values (0–127) on different MIDI CC
numbers depending on the selected Matrix row. Table 3 below shows which parameters (and MIDI CC num-
bers) are controlled by each of the four knobs according to the selected Matrix Row (1–6).
Matrix Control Button and LED
The Matrix Control button selects different options for specific synthesizer parameters based on the currently
selected Matrix Row. The Matrix Control button also sends out continuous controller values (0 or 127) on dif-
ferent MIDI CC numbers depending on the selected Matrix row. The right column in Table 3 below shows
which parameters (and MIDI CC numbers) are affected by the Matrix Control button according to the selected
Matrix Row (1–6). For the 5 parameters that can be set to either on or off (such as Sync On/Off), the LED illu-
minates to indicate that the parameter is set to On.
