The Oberheim SEM synthesizer, originally developed in 1974 by Tom Oberheim, is celebrated for its powerful sound and straightforward design. This monophonic synth has earned a legendary status among musicians for its distinctive tonal character and ease of use. The GForce Oberheim SEM faithfully captures the essence and sonic identity of the original instrument, delivering an authentic experience endorsed by Tom Oberheim himself. With over 400 expertly crafted presets, users can quickly find inspiration and explore a wide range of sounds from warm basses to soaring leads.

Developed in close collaboration with Tom Oberheim and Marcus Ryle, the GForce Oberheim SEM goes beyond mere emulation by incorporating subtle analog nuances that define the original SEM's charm. It features two core oscillators with classic waveforms, envelope generators, a legendary multi-mode filter, and an array of modulation options that recreate the synth's iconic sound. Enhancements such as a third oscillator doubling as an audio-rate LFO, tempo-synced LFOs, and extended performance controls like velocity and aftertouch modulation enrich the sonic possibilities while preserving the simplicity that makes the SEM so accessible.

The GForce Oberheim SEM also includes modern tools designed to enhance music production workflows, including a versatile arpeggiator and sequencer, stereo delay, and lush reverb effects that complement the synth’s character. The extensive preset library is well-organized for quick browsing and is compatible with the GForce Oberheim OB-E, enabling seamless integration and sound design flexibility. This combination of authentic sound, user-friendly interface, and thoughtful enhancements makes the Oberheim SEM an exceptional instrument for crafting expressive monophonic synth sounds.
