The specialist's opinion
Two Legends, one instrument!
Specification
The OB-6 takes Tom Oberheim's classic sound, with its true voltage-controlled oscillators, bipolar filter and amplifiers, and adds modern upgrades such as studio-grade effects, polyphonic sequencer, arpeggiator and more . No other modern poly analog synthesizer can boast such a pedigree or a massive, in-your-face sound signature.
OSCILLATORS
- Two discrete VCOs per voice
- Continuously variable wave shape (sawtooth and variable-width pulse, plus triangle on oscillator 2) per oscillator
- Pulse width per oscillator
- Hard sync: oscillator 1 syncs to oscillator 2
- Square wave sub-octave generator (oscillator 1) per voice
- Low frequency mode (oscillator 2)
- Keyboard tracking on / off (oscillator 2)
- Oscillator detune amount for increased tuning instability, from subtle to extreme
MIX
- Oscillator 1 amount
- Oscillator 1 sub-octave amount
- Oscillator 2 amount
- White noise amount
STATE-VARIABLE FILTER
- Two-pole, resonant, filter per voice with low-pass, high-pass, band-pass, and notch functionality inspired by the original Oberheim SEM filter
- Bi-polar filter envelope amount
- Velocity modulation of envelope amount
- Keyboard tracking: off, half, full
FILTER ENVELOPE
- Four-stage (ADSR) envelope generator
- Velocity modulation of envelope amount
AMPLIFIER ENVELOPE
- Four-stage (ADSR) envelope generator
- Velocity modulation of envelope amount
LOW FREQUENCY OSCILLATOR
- Five wave shapes: sine, sawtooth, reverse sawtooth, square, and random (sample and hold)
- Clock sync (internal or external MIDI clock)
- Initial amount
- Mod destinations: oscillator 1 frequency, oscillator 2 frequency, oscillator 1 and 2 pulse width, filter cutoff, filter mode, amp
X-MOD
- Sources: filter envelope (bi-polar) and oscillator 2 (bi-polar)
- Destinations: oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, filter mode, normal to bandpass filter
AFTERTOUCH
- Source: channel (mono) aftertouch with bi-polar amount
- Destinations: oscillator 1 frequency, oscillator 2 frequency, LFO amount, amplifier envelope amount, filter envelope amount, filter mode
CLOCK
- Master clock with tap tempo
- BPM control and display
- MIDI clock sync
ARPEGGIATOR
- Selectable note value: 16th note, 8th note triplet, 8th note, dotted 8th note, quarter note
- One, two, or three octave range
- Up, down, up / down, random, and assign modes
SEQUENCE
- Polyphonic step sequencer with up to 64 steps and rests
EFFECTS
- Stereo analog distortion
- Dual, 24-bit, 48 kHz digital effects, including: reverb (room, hall, plate, spring), delay (full bandwidth digital delay and emulated bucket brigade), chorus, flanger, phase shifters, and ring modulator
- Delay sync
- True bypass maintains fully analog signal path when digital effects are off
PERFORMANCE CONTROLS
- Full-sized, semi-weighted, 4-octave keyboard with velocity and aftertouch
- Backlit pitch and mod wheels
- Spring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down)
- Transpose controls for an 8-octave range
- Hold switch latches held notes on
- Polyphonic portamento
- Unison (monophonic) mode with configurable voice count, from one to all six voices, chord memory, and key modes
- Manual switch: when on, the front panel is live; what you see is what you hear
PATCH MEMORY
- 500 user and 500 factory programs in 10 banks of 100 programs each
- Direct program access, including single-button access to the current set of 10 programs
IN / OUT
- Left / mono and right audio outputs (2 x 1/4 '' phone jack)
- Headphone output (stereo, 1/4 '' phone jack)
- MIDI in, out, and thru ports
- USB for bidirectional MIDI communication
- Filter cutoff expression pedal input
- Volume expression pedal input
- Sustain footswitch input
- Sequencer start / stop footswitch input
POWER
- IEC AC power inlet for internal power supply
- Operates worldwide on voltages between 100 and 240 volts at 50 to 60 Hz; 30 watts maximum power consumption
PHYSICAL SPECS
- 31.8 '' L x 12.7 '' W x 4.6 ″ H (80.7 cm x 32.3 cm x 11.7 cm)
- 20 lbs (9.5 kg)
