OP-X PRO is a virtual recreation of the legendary
Oberheim OB-X. It is based on the OP-X engine while
offering many additional features for an enhanced
analog feel and tremendous sonic potential.

One of the main additions was to enhance the already
great OP-X filter with multi-mode functionality. The
root concept was derived from the old SEM multi-mode
filter which allowed seamless blending from low-pass
over notch to high-pass with a fixed band-pass
position. This basic concept is enhanced with a
switchable 12/24dB low-pass position and a multi-mode
pole (only high pass in SEM) with itself seamlessly
blendable modes from high-pass over band-pass to
notch. The low-pass-to-multi-mode mix can also be
automated by LFO and the filter envelope.

This mad filter is continuously controllable in every
aspect and will knock your socks off
