If you are looking for a virtual analog synth that can emulate the classic sounds of the Oberheim OB-X and other iconic synths of the 80s, you should check out OP-X PRO-II by SonicProjects. This plugin is a 12-voice synth that can clone the sounds of almost any analog synth, including Minimoog, Prophet, Jupiter-8, and Matrix-12.
OP-X PRO-II is not just a simple emulation, but a faithful recreation of the technical structure of real analog voltage controlled polyphonic synths. Each voice is a discrete separate mono-synth that can be tuned or detuned individually or globally, just like the original hardware. You can also mute or detach voices to create custom setups, such as a true mono-synth or a Prophet-5 with original polyphony behaviour.
But OP-X PRO-II is not limited by the past. It also offers features that extend the sonic possibilities of analog synthesis, such as morphable multimode filters, frequency modulation, ring modulation, hard sync, voice panning, an arpeggiator/midi processor with 32 modes, and an effects processor. With more than 2'500 presets included, you will never run out of inspiration.
OP-X PRO-II is available for Windows and Mac as a VST2, VST3, and AU plugin. You can purchase it for a limited special deal of $179 or â85 from SonicProjects[^1^]. You can also download a demo version and listen to some sound examples on their website[^1^]. If you are a fan of analog synths, you don't want to miss this opportunity to get one of the best virtual Oberheim clones on the market.The Oberheim OB-X was a milestone in the history of analog synthesizers. It was the first Oberheim synth to use a single voice card for each voice, instead of the modular SEM units that were used in previous models. This made the OB-X more compact, affordable, and reliable than its predecessors. The OB-X also featured a microprocessor that automated the tuning process and allowed for 32 user-programmable presets.
The OB-X was released in 1979 to compete with the popular Sequential Circuits Prophet-5, which had been the first fully programmable polyphonic synth on the market. The OB-X offered four, six, or eight voices of polyphony, depending on the model. Each voice had two voltage-controlled oscillators (VCOs), a low-pass filter, two envelope generators, and a noise generator. The OB-X also had a global LFO and a sample and hold circuit for modulation effects.
The OB-X was widely used by many famous musicians in the 80s, such as Rush, Queen, Madonna, Prince, and Jean-Michel Jarre. It was known for its rich and warm sound, especially for brass and string patches. The OB-X was also capable of creating fat basses, punchy leads, and complex pads. Some of the most iconic sounds of the OB-X include the Jump lead by Van Halen, the Lucky Man solo by Emerson, Lake & Palmer, and the Radio Ga Ga chords by Queen.The Oberheim OB-X was not only a powerful synth for creating classic sounds, but also a versatile tool for sound design and experimentation. The OB-X had a unique filter that could operate as a low-pass, high-pass, band-pass, or band-reject filter, giving it a different character than the Moog and ARP filters. The OB-X also had a global LFO and a sample and hold circuit that could modulate various parameters, such as pitch, filter cutoff, pulse width, and noise level.
The OB-X allowed users to create complex and evolving sounds by using the polyphonic portamento, the cross-modulation between the two VCOs, the filter resonance feedback, and the voice detuning. The OB-X also had a split keyboard mode that enabled users to play two different sounds on each half of the keyboard. Some of the sound design techniques that users could apply on the OB-X include:
Creating metallic and bell-like sounds by using frequency modulation (FM) between the two VCOs.
Creating rich and organic pads by using voice detuning and filter resonance feedback.
Creating rhythmic and arpeggiated patterns by using the sample and hold circuit and the polyphonic portamento.
Creating dynamic and expressive leads by using the paddle levers for pitch bend and modulation.
The Oberheim OB-X was a synth that inspired many artists to explore new sonic territories and create memorable sounds. Some of the examples of sound design on the OB-X include:
The laser harp sound on Jean-Michel Jarre's Rendez-Vous album, created by using FM and filter resonance.
The sync lead sound on Van Halen's Jump, created by using hard sync and pitch bend.
The swelling pad sound on Rush's Tom Sawyer, created by using voice detuning and filter cutoff.
The plucked string sound on Queen's Radio Ga Ga, created by using pulse width modulation and filter envelope. 061ffe29dd
