Sequential Prophet 6

Prophet-6 specifications

Oscillators:

Two newly developed, discrete VCOs per voice

Infinitely crossfadeable waveforms (sine, sawtooth, variable-width square, rectangle) per oscillator

Adjustable pulse width per oscillator

Hard sync: oscillator 1 synchronises with oscillator 2

Triangle sub-oscillator (oscillator 1) per voice

LFO mode (oscillator 2)

Switchable keyboard tracking (oscillator 2)

Adjustable slop intensity of the oscillators for increased tuning instability, from subtle to extreme

Mixer:

Amount/proportion oscillator 1

Amount/proportion sub-octave oscillator 1

Amount/proportion oscillator 2

Amount/share white noise

High pass filter:

Two-pole, resonant high-pass filter per voice

Amount/proportion of the bipolar envelope generator

Modulation of the envelope intensity via the velocity response

Keyboard tracking: off, half intensity, full intensity

Low-pass filter:

Four-pole, resonant low-pass filter per voice, inspired by the filter in the original Prophet-5

The filter can be set to self-oscillate using the resonance control

Amount/proportion of the bipolar envelope generator

Modulation of the envelope intensity via the velocity response

Keyboard tracking: Off, half intensity, full intensity

Filter envelope:

Four-stage envelope generator (ADSR)

Envelope:

Four-stage envelope generator (ADSR)

Modulation of the envelope intensity via the velocity response

LFO:

Five waveforms: Triangle, sawtooth, inverted sawtooth, square and random (sample and hold)

Clock synchronisation (to an internal or external MIDI clock)

Initial modulation intensity

Modulation targets: Oscillator 1 and 2 frequency, Oscillator 1 and 2 pulse width, and the filter onset frequencies of the low-pass and high-pass filters.

Poly MOD:

Sources: Filter envelope (bipolar) and oscillator 2 (bipolar)

Targets: Frequency, waveform and pulse width of oscillator 1 as well as the filter cut-off frequencies of the low-pass and high-pass filters

Aftertouch:

Source: Channel aftertouch (mono) with bipolar intensity control

Destinations: Frequency of oscillators 1 and 2, LFO intensity, intensities of the volume envelope, the envelope for the low-pass filter and the envelope for the high-pass filter

Clock:

Master clock with tap tempo

BPM control and display

MIDI clock synchronisation

Arpeggiator:

Selectable note values: sixteenth note, eighth note triplet, eighth note, dotted eighth note, quarter note

One, two or three octave ranges

Operating modes: up, down, oscillate, random, assignable

Sequencer:

Polyphonic step sequencer with up to 64 steps and support for pauses

Effects:

Analogue stereo distortion

Double digital effects with a resolution of 24 bit/48 kHz. Available for selection: Reverb (room, hall, plate, spring), delay (digital with full bandwidth and emulated bucket brigade circuit), chorus, flanger, phaser and ring modulator

Delay synchronisation

True bypass ensures a completely analogue signal path when digital effects are switched off

Performance control:

Full-format, lightly weighted 4-octave premium keyboard from Fatar with velocity response and aftertouch

Illuminated pitch and modulation wheels

Pitch wheel with centring spring and selectable range per programme (1 to 12 semitones up and down).

Transpose buttons with a range of eight octaves

Hold button locks played notes

Polyphonic glide (portamento)

Unison mode (monophonic) with configurable number of voices, from one to all six voices, several modes for voice distribution

Preset button: When switched off, the control panel is active. Here you can hear the exact sound of the current settings of the control elements.

Programme memory:

500 user and 500 factory sounds in ten banks with 100 programmes each

Direct programme access, including one-button access to the current set of ten programmes as on the Prophet-5

Connections:

Left/mono and right output (2 x 6.35 mm jack sockets)

Headphone output (6.35 mm stereo jack socket)
