Oberheim OB-X vs. SonicProjects OP-X PRO-II

video upload by

"A dry 1:1 comparison of the SonicProjects OP-X PRO-II virtual Oberheim VST AU software synth to an Oberheim OB-X Rev.2.

Both the OB-X and the OP-X PRO-II were recorded 100% dry and unprocessed over an RME Fireface UC - the OB-X over the line inputs and the OP-X PRO-II via optical cable over the optical S/PDIF-input. What you hear is the pure 24-bit recording. Of course there unfortunately will be some compression artefacts from YouTube.

Used hardware and software:

Korg MicroKey 37 MIDI keyboard
MacBook Air 2020 M1
macOS Monterey 12.1
Logic Pro 10.7.2
RME Fireface UC
SonicProjects OP-X PRO-II version 1.2.6 synth interface standard
Obererheim OB-X Rev. 2 with 6 voices installed

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 voice by voice in every detail with the voice-based tuning features of OP-X PRO-II for a perfect match to the real synth.

To copy the bright sound OP-X PRO-II uses the BRL (brilliant) filter setting (DMP button, second button above voice mutes in the synth interface) 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 used patches are available in the synth's included banks library in this bank: Downloaded / PROII_COMPARISON"
