Critic Reviews

SonicProjects OP-X Pro II review | MusicRadar

musicradar.com

SonicProjects OP-X PRO-II impresses with its versatile modern take on the classic Oberheim synths, offering updated features and unique editing capabilities that make it stand out in the realm of vintage emulations. It excels at producing a wide range of sounds, from pads to bass, and captures the analogue spirit ingeniously with its separate voice design. However, the clumsy and sometimes confusing interface detracts slightly from its overall appeal. Despite this drawback, it remains the best software option for those seeking the distinctive Oberheim sound.

Extremely thick FAT sound, faithful to the original OB-X SEMs

This one is the BEST Oberheim clone (on steroids). Sonic Projects captured the sound of the original Oberheim SEM oscillators from the OB-X (the OB-Xa and later models used the Curtis chips that didn't sound quite as good). Because of its big sound, it can actually pull-off some amazing sounds traditional to the Roland Jupiter and Prophet 5. The VST has an large amount of options & routings, and can be mapped to a lot of popular MIDI synth-knob controllers to be controlled in real-time, such as those made by Soundforce.

amazing !

I really love the way OP-X PRO-II sounds and how close the patches of the "Famous Bank" come to original famous sounds such as Van Halen´s "Jump" analogue brass sound and many more. SonicProjects OP-X PRO-II comes with 2'500 presets!
