On this site you will get to know the classic Sonicprojects OP-X PRO. Note that OP-X PRO has been discontinued in favour of its big brother OP-X PRO-II. So this former product page only still serves for informative purpose.

The multimode filter Click to enlarge >> One of the main additions was to enhance the already great OP-X filter with multimode functionality. The root concept for it was derived from the old SEM multimode filter which allowed seamless blending from lowpass over notch to highpass with a fixed bandpass position. This basic concept was now even enhanced with a switchable 12/24dB lowpass position and a multimode pole (only high pass in SEM) with itself seamlessly (!) blendable modes from highpass over bandpass to notch. Not enough with this the lowpass-to-multimode mix can be automated by lfo and the filter envelope. So this mad filter is continuously controllable in every aspect and will simply knock you out of the socks!   learn more
