The Oberheim OB-E Black Friday deal from GForce Software takes 52% off this synth plugin, so it comes to $79.99 until Dec 1, 2026.
OB-E is GForce's software version of the Oberheim 8-Voice. The maker says it is the first software instrument to carry Tom Oberheim's personal endorsement.
It is built on the Synthesizer Expander Module (SEM) design, also known as the EVS. Eight SEMs run side by side, which gives you an eight-note polyphonic synth with an octaphonic architecture.
Each SEM has two VCOs with Pulse and Sawtooth waveforms, two ADS envelope generators, one LFO and a multi-mode filter. On its own a SEM is monophonic. Trigger eight of them from a polyphonic keyboard and you get the 8-Voice.
The maker adds that the eight modules are slightly different from each other, and that this interaction is a big part of the sound. OB-E builds those small inaccuracies into every SEM.
GForce adds a third VCO that can double as an audio-rate LFO for each SEM. Velocity, polyphonic aftertouch and MPE control are also on board.
GForce worked with Tom Oberheim and Marcus Ryle, who engineered at Oberheim in the 1980s, on the V2 update. It brought a Vintage control and a refined Detune parameter, which add more realistic tuning drift in line with the original instrument.
The update list also includes:
The 8-step sequencer takes its cue from the original MS-1 sequencer, with more flexibility. In keyboard Split mode, with the sequencer routed to SEM 8, you can build a three-part soundscape inside a single patch.
Play modes are Mono, Mono Legato, Poly and Unison, plus a round-robin mode where each note takes a new voice. A routable stereo delay and a reverb are built in.
The filters use zero delay feedback. Zoom enlarges a single SEM so its front and rear panels sit side by side.
Group mode edits all modules at once. Individual SEMs can be copied, pasted and saved.
The 700+ factory patches were designed by Dave Spiers and other sound designers. Each is tagged and categorised, and the librarian supports arrow-key navigation.
OB-E also includes an Oberheim OB-EZ license.
Yes. The Oberheim OB-E synth plugin from GForce Software is 52% off, which brings it to $79.99. The deal runs until Dec 1, 2026.
You get the eight-SEM instrument with 700+ factory patches, an 8-step sequencer, a stereo delay and a Matrix Reverb. Drum Mode comes with 10 drum kit presets. An Oberheim OB-EZ license is also included.
It supports VST3 and runs natively on Apple Silicon. Version 2 is available for both macOS and Windows.
The Vintage knob, added in V2 alongside a refined Detune parameter, dials in realistic musical inaccuracies in line with the original 8-Voice. GForce developed it with guidance from Tom Oberheim and Marcus Ryle.
