Sonic Projects OP-X PRO-II v1.3.1 Regged-R2R

Sonic Projects OP-X PRO-II v1.3.1 Regged-R2ROP-X PRO-II is a virtual analog synth originally based on the famous Oberheim OB-X. During its evolution the engine however was extended with features borrowed from various other iconic synths of this era, which makes it incredibly versatile. The range of possible sounds reaches from early monophonic synths over classics like OB-X and Jupiter-8 up to Matrix-12.

The engine of OP-X PRO-II exactly clones the technical structure of real analog voltage controlled polyphonic synths of the 80s, which were based on separate discrete circuits for each voice, which were slightly varying in sound by default because of device tolerances, and could be tuned globally by adding an offset voltage (auto-tune) or individually by adjusting trimpots on the circuit boards. All of this is implemented in OP-X PRO-II too. Which means: The single voices in fact are discrete separate mono-synths (no voice-cloning!) which slightly vary in sound by default (untuned), but can be quickly tuned or again de-tuned globally (also seamlessly if needed) by the click of dedicated buttons (imitating auto-tune) for different parameter groups. Virtual trimpots (imitating the calibration trimpots on the voice-boards) finally also allow to tune pairs of voices individually to achieve a custom detuning if needed.
