Sequential

DESCRIPTIONDave Smith Instruments OB-6 The OB-6, created from a collaboration between Dave Smith and Tom Oberheim, is a six-voice, fully analog two oscillator-per-voice synthesizer. Both oscillators have variable wave shapes from Saws to Pulse, (with a triangle wave on oscillator two.) The oscillators are then fed thru the iconic Oberheim SEM filter, with high pass, low pass, notch and bandpass outputs. These are then feed into analog VCAs, providing an all analog signal path. Modulation sources can be assigned to essentially any parameter with no menu diving. Each control has a dedicated knob on the front panel. Also included is a dual effects section, that gives studio-quality delays, reverbs, chorus, as well as faithful recreations of the classic Oberheim phase shifter and ring mod. All the effects are 24-Bit, 48kHz digital resolution with true bypass, keeping the analog signal path when not in use. A multimode arpeggiator and 64-step polyphonic step sequencer (six notes per step) are also included to make the OB-6 an entire synthesizer workstation. When not all voices are used by the sequencer, one can perform on the remaining voices while the sequence continues. The keyboard is semi-weighted, with four octaves. It has full-size keys for those used to playing pianos and electric keyboards.OB-6 Synthesizer Features OSCILLATORSTwo discrete VCOs per voiceContinuously variable wave shape (sawtooth and variable-width pulse, plus triangle on oscillator 2) per oscillatorPulse width per oscillatorHard sync: oscillator 1 syncs to oscillator 2Square wave sub-octave generator (oscillator 1) per voiceLow frequency mode (oscillator 2)Keyboard tracking on/off (oscillator 2)Oscillator detune amount for increased tuning instability, from subtle to extreme MIXEROscillator 1 amountOscillator 1 sub-octave amountOscillator 2 amountWhite noise amount STATE-VARIABLE FILTERTwo-pole, resonant, filter per voice with low-pass, high-pass, band-pass, and notch functionality inspired by the original Oberheim SEM filterBi-polar filter envelope amountVelocity modulation of envelope amountKeyboard tracking: off, half, full FILTER ENVELOPEFour-stage (ADSR) envelope generatorVelocity modulation of envelope amount AMPLIFIER ENVELOPEFour-stage (ADSR) envelope generatorVelocity modulation of envelope amount LOW FREQUENCY OSCILLATORFive wave shapes: triangle, sawtooth, reverse sawtooth, square, and random (sample and hold)Clock sync (internal or external MIDI clock)Initial amountMod destinations: oscillator 1 frequency, oscillator 2 frequency, oscillator 1 and 2 pulse width, filter cutoff, filter mode X-MODSources: filter envelope (bi-polar) and oscillator 2 (bi-polar)Destinations: oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, filter mode AFTERTOUCHSource: channel (mono) aftertouch with bi-polar amountDestinations: oscillator 1 frequency, oscillator 2 frequency, LFO amount, amplifier envelope amount, filter envelope amount CLOCKMaster clock with tap tempoBPM control and displayMIDI clock sync ARPEGGIATORSelectable note value: 16th note, 8th note triplet, 8th note, dotted 8th note, quarter noteOne, two, or three octave rangeUp, down, up/down, random, and assign modes SEQUENCERPolyphonic step sequencer with up to 64 steps and rests EFFECTSStereo analog distortionDual, 24-bit, 48 kHz digital effects, including: reverb (room, hall, plate, spring), delay (full bandwidth digital delay and emulated bucket brigade and tape delays), chorus, flanger, phase shifters, and ring modulatorDelay syncTrue bypass maintains fully analog signal path when digital effects are off PERFORMANCE CONTROLSFull-sized, semi-weighted, 4-octave keyboard with velocity and aftertouchBacklit pitch and mod wheelsSpring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down)Transpose controls for an 8-octave rangeHold switch latches held notes onPolyphonic portamentoUnison (monophonic) mode with configurable voice count, from one to all six voices, chord memory, and key modesManual switch: when off, the front panel is live; what you see is what you hear PATCH MEMORY500 user and 500 factory programs in 10 banks of 100 programs eachDirect program access, including single-button access to the current set of 10 programsGUARANTEE New Gear We are authorized dealers for a number of great companies that back their products with standard warranties.
