What OB-E is
OB-E is GForce’s software instrument based on the Oberheim 8-Voice, using an eight-voice SEM architecture. Each SEM provides three oscillators, a multimode filter, two envelopes, and modulation controls. Performance modes include polyphonic, monophonic, mono legato, unison, and split keyboard operation. An eight-step sequencer, stereo delay, and reverb are included. More than 700 factory patches are organized by tags and categories in a patch librarian. OB-E supports polyphonic aftertouch and MPE control, and every purchase includes a complimentary Oberheim OB-EZ license. It runs as a standalone application and plug-in on macOS and Windows. macOS formats include AudioUnit, AAX, VST, and VST3; Windows includes AAX, VST, and VST3. The Oberheim OB-E plan costs €173.22, paid once. A demo lasts six hours or seven days, whichever is longer, with Alpha Patches only.
