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 has 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. It runs as a standalone application on macOS and Windows, with plug-in formats for both systems. macOS supports AudioUnit, AAX, VST and VST3; Windows supports AAX, VST and VST3. Every purchase includes a complimentary Oberheim OB-EZ license. The plan costs €173.22, paid once. A demo lasts six hours of use or seven days, whichever is longer, and restricts access to Alpha Patches.
