Apart from the obvious and familiar controls OP-X PRO-II additionally has a lot
of active GUI zones and multiple functional controls that can access a lot of
useful additional features or calibration jobs. Here's a useful overview over these zones:
Seamless parameter control:
1, 4: Seamless detuning control
Click on OSC, FILT, ENV or 5 and drag the mouse vertically to adjust detunings seamlessly. Small popping
up displays will show the current value.
2, 3, 4: Seamless level control
Click on the labels above the buttons to seamlessly control the levels of oscillator 1,
oscillator 2 and noise. A small popping up display will show the current value.
6, 7, 8, 9: Tuning trimpot calibration
Click on the marked zones to automatically calibrate all six trimpots. Right side:
sets all trimpots to equal tuning. Left side: resets all six trimpots to the standard
detuning mode (twelve o'clock). Can be helpful to find the base for own custom detunings.
10, 11, 12: Knob reset
Click on OM or PM to reset the knobs to zero, which makes sure there's no filterenv
modulation left at all. Click on Tune to reset master tune to 12 o'clock which is the
13: Multimode trimpots reset
Click on OSC2 to reset all multimode trimpots to zero. This can be helpful if you
want to return to pure lowpass filtering at once.
14: Lever modes
Click in the number display above the square button and drag the mouse vertically up
or down to access a lot of diferent interval and function settings of the pitchwheel and
modwheel. Have a look at the manual for details.

Multi functional buttons:
18: Sampled vibrato
When S/H is active click two times on AMP until the LED shines blue to turn sample and hold

separate lever LFO. The result is a repeating stepped wave.
19: Bright modes
The DMP button now allows for 4 different brightness modes. LED dark: standard mode,
The filter smooths down the heights of the oscillators a bit even when fully opened.
DMP: Dampes the filter which can be useful in combination with keyboard tracking.
CLR: Clear mode. The filters can open fully at let pass the oscillators unchanged at
highest cutoff setting. BRI: Brilliant setting. Generally the same, but with atill a bit of
added brightness and edge in the highest frequencies.
20: Manual LFO trigger
When clicking this button into the blue mode the LFO is triggered by played notes.
The starting phase then can be freely adjusted with the beating trimpot (25):
21: LFO starting delay
When clicking this button into the blue mode the LFO starting can be delayed and faded
in with variable amount. A second click on the button inverts the phase. The starting
