Active Zones

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.

One-click calibration:


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 standard tuning.

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.

Lever modes:

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.

Pan presets:

15: Mono mode

Click on Voice to reset all pans to center for perfect mono. This can save you a lot of work when mono is needed.

16: Variable stereo

Click on Pans and drag the mouse vertically up or down to spread all pans at the same away from the center position in alternating mode for variable stereo.

17: Variable stereo

Click on 1, 2, 3, 4, 5 or 6 to access various panning presets that can be useful for different situations or simply to check out the effect of different settings.

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 to sampled vibrato. In this state not anymore noise is sampled, but the output of the 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 delay then can be adjusted with the itself multifunctional Velo/Mode knob (26), the rising time with the itself multifunctional Stp/Speed knob (27):

22: Invert filter envelope

When clicking this button into the blue mode the filter envelope is being inverted. You may need to adjust the envelope amount knob then accordingly to hear an effect.
