The Sequential OB-6 Module rocks six discrete analog voices with two oscillators and a sub oscillator per voice. Naturally, OB-6 Module is equipped with Dave's infamous X-Mod (two sources, five destinations). On top of all that, there's a 64-step polyphonic step sequencer, two digital effects engines (with studio-grade reverbs, delays, chorus, flangers, and accurate re-creations of Mr. Oberheim's renowned ring mod and phase shifter), and an advanced arpeggiator. To control all this firepower, you have a knob-per-function top panel that makes for quick, intuitive on-the-fly tweaks. From funk-laden basses and snarling, in-your-face leads to gloriously celestial pads, the OB-6 Module will make your synth dreams come true.\u003c\/p\u003e\t\t\n\t\t\t\t\t\u003ch1\u003eHeart of the beast: Oberheim's classic SEM\u003c\/h1\u003e\t\t\t\t\n\t\t\u003cp\u003eOberheim's original SEM (Synthesizer Expansion Module) formed the core of Tom's renowned 4-voice and 8-voice synths of the 1970s. The SEM, in updated form, is also the core of the OB-6 Module analog sound engine. With two discrete voltage-controlled oscillators and a sub oscillator per voice, the OB-6 Module gives you the flexibility of waveshapes that are continuously variable between sawtooth and variable-width pulse. Oscillator 2 also sports a triangle wave. The classic Oberheim-style state-variable, 2-pole resonant filter features lowpass, highpass, bandpass, and notch functionality. The all-analog signal path is completed by the OB-6 Module's voltage-controlled amplifiers.\u003c\/p\u003e\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"940\" height=\"480\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/07\/imgi_37_OB-6-Right-Slideshow-1024x523.png\" alt=\"imgi_37_OB-6-Right-Slideshow\" title=\"imgi_37_OB-6-Right-Slideshow\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"940\" height=\"480\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/07\/imgi_39_OB-6-Desk-Rear-Product-1024x523.png\" alt=\"imgi_39_OB-6-Desk-Rear-Product\" title=\"imgi_39_OB-6-Desk-Rear-Product\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\u003ch1\u003eX-Mod, Poly Step Sequencer, and Arpeggiator\u003c\/h1\u003e\t\t\t\t\n\t\t\u003cp\u003eThe OB-6 Module is spec'd out with Dave Smith's brilliant X-Mod, which makes it easy to achieve killer sounds via modulation. The filter envelope and oscillator 2 are the sources, and they both give you bi-polar control. The five destinations are oscillator 1 frequency, oscillator 1 waveshape, oscillator 1 pulse-width, filter mode, and filter cutoff. The polyphonic step sequencer lets you program polyphonic sequences (up to 64 steps, up to six notes per step), complete with rests, and sync them to external MIDI clock. The full-function arpeggiator can also be synced to external MIDI clock. You can configure the OB-6 Module's Unison Mode voice count for up to six voices. And to maximize your sonic firepower, the OB-6 Module is spec'd with a poly chain feature the lets you pair any two OB-6s for 12-voice operation.\u003c\/p\u003e\t\t\n\t\t\t\t\t\u003ch1\u003eSequential \/ Oberheim OB-6 Module Features:\u003c\/h1\u003e\t\t\t\t\n\t\t\u003cul\u003e\u003cli\u003e2 oscillators and sub oscillator per voice\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003eContinuously variable waveshapes\u003c\/li\u003e\n\u003cli\u003eState-variable filter\u003c\/li\u003e\n\u003cli\u003e64-step polyphonic step sequencer\u003c\/li\u003e\n\u003cli\u003eFull-function arpeggiator\u003c\/li\u003e\n\u003cli\u003e2 digital effects engines\u003c\/li\u003e\n\u003cli\u003eKnob-per-function top panel\u003c\/li\u003e\n\u003cli\u003ePoly chain feature lets you pair any 2 OB-6s for 12-voice operation\u003c\/li\u003e\n\u003c\/ul\u003e\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"940\" height=\"480\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/07\/imgi_38_OB-6-Front-Slideshow-1024x523.png\" alt=\"imgi_38_OB-6-Front-Slideshow\" title=\"imgi_38_OB-6-Front-Slideshow\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\u003ch1\u003eSpecifications\u003c\/h1\u003e\t\t\t\t\n\t\t\u003ch4\u003e\u003cstrong\u003eOSCILLATORS\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo discrete VCOs per voice\u003c\/li\u003e\n\u003cli\u003eContinuously variable wave shape (sawtooth and variable-width pulse, plus triangle on oscillator 2) per oscillator\u003c\/li\u003e\n\u003cli\u003ePulse width per oscillator\u003c\/li\u003e\n\u003cli\u003eHard sync: oscillator 1 syncs to oscillator 2\u003c\/li\u003e\n\u003cli\u003eSquare wave sub-octave generator (oscillator 1) per voice\u003c\/li\u003e\n\u003cli\u003eLow frequency mode (oscillator 2)\u003c\/li\u003e\n\u003cli\u003eKeyboard tracking on\/off (oscillator 2)\u003c\/li\u003e\n\u003cli\u003eOscillator detune amount for increased tuning instability, from subtle to extreme\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eMIXER\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOscillator 1 amount\u003c\/li\u003e\n\u003cli\u003eOscillator 1 sub-octave amount\u003c\/li\u003e\n\u003cli\u003eOscillator 2 amount\u003c\/li\u003e\n\u003cli\u003eWhite noise amount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eSTATE-VARIABLE FILTER\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-pole, resonant, filter per voice with low-pass, high-pass, band-pass, and notch functionality inspired by the original Oberheim SEM filter\u003c\/li\u003e\n\u003cli\u003eBi-polar filter envelope amount\u003c\/li\u003e\n\u003cli\u003eVelocity modulation of envelope amount\u003c\/li\u003e\n\u003cli\u003eKeyboard tracking: off, half, full\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eFILTER ENVELOPE\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour-stage (ADSR) envelope generator\u003c\/li\u003e\n\u003cli\u003eVelocity modulation of envelope amount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eAMPLIFIER ENVELOPE\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour-stage (ADSR) envelope generator\u003c\/li\u003e\n\u003cli\u003eVelocity modulation of envelope amount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003ePERFORMANCE CONTROLS\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull-sized, semi-weighted, 4-octave keyboard with velocity and aftertouch\u003c\/li\u003e\n\u003cli\u003eBacklit pitch and mod wheels\u003c\/li\u003e\n\u003cli\u003eSpring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down)\u003c\/li\u003e\n\u003cli\u003eTranspose controls for an 8-octave range\u003c\/li\u003e\n\u003cli\u003eHold switch latches held notes on\u003c\/li\u003e\n\u003cli\u003ePolyphonic portamento\u003c\/li\u003e\n\u003cli\u003eUnison (monophonic) mode with configurable voice count, from one to all six voices, chord memory, and key modes\u003c\/li\u003e\n\u003cli\u003eManual switch: when on, the front panel is live;
