OBERHEIM OB-6 Keyboard Synthesizer

The OB-6® is a once-in-a-lifetime collaboration between the two most influential designers in poly synth history, Dave Smith and Tom Oberheim. The OB-6 takes the classic bold Tom Oberheim sound — with its true voltage-controlled oscillators, 2-pole filter, and amplifiers — and adds modern enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. No other modern analog poly synth can boast such a pedigree or such a massive, in-your-face sonic signature.
The OB-6 sound engine is inspired by Tom’s original SEM, the core of his acclaimed 4-voice and 8- voice synthesizers. It features two discrete voltage-controlled oscillators (plus sub-oscillator) per voice with continuously variable waveshapes (sawtooth and variable-width pulse, plus a triangle wave on oscillator 2). The classic Oberheim-inspired 2-pole, state-variable, resonant filter provides low-pass, high-pass, band-pass, and notch functionality. Voltage-controlled amplifiers complete the all-analog signal path.
The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom’s original phase shifter and ring modulator. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path.
Also present is X-Mod, which expands the tonal palette and makes it easy to create dramatic and unconventional sounds. Modulation sources are filter envelope and oscillator 2, both with bi-polar control. Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, and filter mode. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well. Unison mode features configurable voice count (1-6 voices), chord memory, and key modes.

Pedal Inputs

Pedal Inputs: Yes

The pedal input allows you to connect an external pedal that expands the instrument's control capabilities and contributes to a richer musical expression, increasing flexibility and expressiveness when playing and creating music.

Envelope: ADSR

The ADSR (Attack, Decay, Sustain, Release) type envelope filter gives you precise control over the dynamics and shape of your sound. The ADSR components are detailed as follows: Attack: Specifies how quickly the sound reaches its maximum volume upon activation. Decay: Specifies the time it takes for the volume to drop from maximum to sustain. Sustain: Represents a stable volume level that is maintained as long as the sound is active. Release: Specifies how quickly the volume fades to zero after the sound has been released.

Oscillators: Yes

A powerful oscillator system allows users to create rich and variable sound textures. Oscillators can generate a variety of waveforms, including sine, square, triangle, and noise, allowing for creativity and experimentation.

LFO: Yes

An LFO, or low frequency oscillator, brings electronic sound to life. It adds movement and interest to synthetic sounds and effects, playing an important role in both subtle synthesis and bold sound design. However, you won't hear the LFO itself because it acts as a modulator. This means that it does not directly affect the audio signal, but adjusts other parameters such as oscillator pitch and filter clipping.

MIDI Interface: Yes

It supports MIDI, allowing you to connect and communicate with other MIDI-compatible devices. This feature extends control and integration into the larger music environment, increasing flexibility and creativity in music creation.

Headphone Output: Yes

The headphone output allows direct connection of headphones for private listening. This output provides a convenient way to enjoy the sound without disturbing others or ambient noise.

Polyphony: 6

The polyphony of this instrument allows up to <%=tp_value % notes to be played simultaneously, providing rich and complex musical possibilities.

Number of Keys: 49

This instrument has 49 keys, equivalent to 4 octaves, providing a wide range of tones for a variety of musical applications.

Keyboard Type

  • Semi Weighted with Aftertouch
  • Fatar

Aftertouch: Yes

Aftertouch technology on the keys allows musicians to add a new level of expression to their playing. When a key reaches the bottom of its stroke, the pressure exerted on the key can continue to be sensed and used to control various aspects of the sound, such as vibrato, volume, or tone modulation.

Arpeggiator: Yes

The Arpeggiator transforms chords into sequences of individual notes played in various rhythmic and melodic patterns. Instead of playing the chords as a harmonic whole, the Arpeggiator breaks the chords into individual notes and plays them sequentially according to the selected algorithm.

Modulation: Yes

Modulation allows you to change different aspects of the sound in real time, opening up a wide range of creative possibilities. For example, it can affect the pitch of the sound, creating a vibrato effect, or it can change the amplitude of the signal, creating a tremolo effect. It can also adjust filtering to create smooth transitions between frequency bands and dynamic textures. Modulation can also be used to change the character of the sound depending on the time or intensity of playing, giving the sound a lively and moving character.

Pitch Bend: Yes

The Pitch Bend allows smooth pitch changes, adding expressiveness to musical expression. Often used to create effects such as glissando or vibrato, this feature allows the player to make subtle or dramatic changes to the sound in real time. Pitch bend allows musicians to create smooth transitions between notes, increasing the dynamics and expressiveness of their performances.

Sequencer: Yes

The sequencer provides musicians with a tool for composing and arranging music, allowing them to create and edit musical sequences. This feature allows you to record and play back repeating patterns. This makes it easy to create complex rhythms and melodies. The sequencer also allows you to layer different musical elements on top of each other, sync with other devices, and adjust parameters in real time. This flexibility makes the sequencer an invaluable tool for producing music, experimenting with new sounds and creating original compositions.
