Oberheim OB-6 6-Voice Analog Synthesizer

The OB-6 is a once-in-a-lifetime collaboration between two of the most influential synth designers in history — Dave Smith and Tom Oberheim. It’s an all-analog, 6-voice poly synth with voltage-controlled oscillators, a state-variable filter, and voltage-controlled amplifiers, inspired by Tom’s original SEM design — the bedrock of his legendary 4-voice and 8-voice synthesizers. Manufactured and sold by Dave Smith Instruments, the OB-6 features six discrete analog voices with two oscillators (plus sub oscillator) per voice, continuously variable waveshapes with triangle, sawtooth, and variable-width pulse waves, X-mod with 2 sources and 5 destination, a 64-step polyphonic step sequencer, dual digital effects that include faithful recreations of Tom’s acclaimed phase shifter and ring modulator, a full-featured arpeggiator, and a powerful, in--face, sonic signature like no other instrument. This analog powerhouse is packed into a four-octave, semi-weighted keyboard with velocity and channel aftertouch, making it perfect for stage or studio.The latest OS from Sequential adds these much-anticipated features:• Support for MPE (MIDI Polyphonic Expression). This enables the Prophet-6 and OB-6 to respond to MPE-driven controllers such as the LinnStrument, Expressive E Osmose, Roli Seaboard series and others.• Prophet-5 Rev 4-style “vintage” mode. This gives the Prophet-6 and OB-6 a looser, more organic sound that emulates the behavior of vintage synthesizers where the behavior of individual oscillators, filters and envelopes vary from voice to voice.• Improved aftertouch curves for enhanced expressiveness when using the Prophet-6 and OB-6’s own keyboard, significantly enhancing the expressivity of both instruments.
