Here’s an analog vs virtual analog comparison, via virtualoberheim, of the SonicProjects OP-X PRO-II virtual Oberheim VSTi software synth for Windows and a vintage Oberheim OB-X Rev.2.
The lower manual in the video is an USB MDI master keyboard (an Emu Xboard 61) which drives OP-X PRO-II hosted in Steinberg Cubase 5. No effects or any other treatments were involved, both OB-X and OP-X PRO-II were recorded directly to disk, OB-X over the line inputs of an RME HDSP 9632.
The video switches quickly back and forth between the two sources, making it easy to listen for differences.
Check it out and let us know what you think! Can you hear differences between the vintage Oberheim and its virtual recreation?
The exact detunings (deviating filter settings, warm up pitch drift, etc.) and the individual pan settings of the voices of OB-X have been copied with the voice-based tuning features of OP-X PRO-II.
To copy the bright sound OP-X PRO-II uses the BRL (brilliant) filter setting (DMP button, second button above voice mutes). which is dedicated to copy the sound character of the early OB-X and allows the filter to open into the ultra sound area and adds some extra shine in the heights.
The patches as used in the video:
- 00:02 Preset 04 B3 – Slow Upsweep

The letter number combinations are the physical memory locations of the patches in the used original synth which were copied with OP-X PRO-II for the comparison.
