Sequential’s most famous instrument, the Prophet-5, the poly synth that started it all. The Sequential Prophet-6 takes the best qualities of the Prophet-5 and adds some nice touches that the original never had, such as stereo outputs, velocity and aftertouch sensitivity, dual digital effects, a high-pass filter, a polyphonic step sequencer, an arpeggiator, and of course, MIDI.
Getting Started The Prophet-6 is a six-voice, polyphonic analog synthesizer with voltage-controlled oscillators, filters, and amplifiers. It was designed to provide all of the warmth and presence of a vintage-era synth with the added convenience and stability of a state-of-the-art, modern instrument. The Prophet-6 is first and foremost a performance instrument.

Moving to the Next Level The Prophet-6 is filled with possibilities for sound creation. Although we realize that you’d rather spend your time exploring its capabilities, we’d like to point you toward a few things that will help you tailor the instrument to your needs.

Mixer The Mixer section is where you set the levels of the various sound generators on the Prophet-6. These include Oscillator 1, Oscillator 2, Sub Octave (Oscillator 1 sub oscillator) and the white noise generator. You must turn up at least one of these in order to make sound with the Prophet-6.

To give you a real-world example, the main difference between the sound of the wind and the sound of a snare drum is that they have very different volume envelopes. Otherwise, they are essentially both white noise. Wind has a relatively slow attack, a long sustain, and a long decay and release.

Arpeggiator The Prophet-6 has a full-featured Arpeggiator. Turn it on, hold a chord and the Prophet-6 will play a pattern based on the individual notes held. Choose a mode (up, down, random, etc.), an octave range (1, 2, or 3), and a tempo, then pair it with an appropriately percussive sound, and you’ll be surprised at the number of creative things you can do.

Distortion The Prophet-6 provides stereo analog distortion. This can be used to add warmth, harmonic complexity, and an aggressive edge to sounds. The character of the distortion is affected by the harmonic content of a program. Sounds with more high-end will sound different than sounds with fewer harmonics.

Key Assign Modes Key Assign (sometimes called note priority) determines what note has priority when more than one note is played on the keyboard or via MIDI: • Low-note priority (LO) is most common in vintage synths and is often used for playing trills by holding a note and repeatedly tapping a lower note.

Preset switch toggles “live panel” mode on and off. In live panel preset mode the Prophet-6 ignores the currently active preset and reverts to the current front-panel settings of its knobs and switches. In other words, what you see on the front panel is what you hear. This is a great mode for learning, experimentation, and instant gratification.

Modulation Wheel The Mod wheel controls the amount of modulation applied to any destina- tions chosen in the section. This allows you to frequency oscillator “perform” LFO modulation in real time by moving the Mod wheel. This is a great way to add expressiveness to a sound or performance.

Aftertouch Aftertouch is a performance feature that allows you to add modulation to a sound by applying additional pressure to a key after the key is already down. The greater the pressure applied, the more modulation is applied. The Prophet-6 provides monophonic (or “channel”) aftertouch, which means that applying pressure to any key within a chord will apply modu- lation to all notes currently held.

2. The front panel LEDs and display begin flashing as the Prophet-6 performs its auto-calibration procedure. Don’t turn off the power while it’s doing this. 3. When finished, the front panel controls will return to normal and you can play the Prophet-6 again. Calibrating the Prophet-6 Dave Smith Instruments...
Calibrating the Pitch and Mod Wheels In general, the Pitch and Mod wheels shouldn’t require re-calibration. However, if you experience what seems like a persistent problem with either of them, the Prophet-6 has built-in auto-calibration procedure that you can use to remedy the problem. To calibrate the Pitch and Mod wheel’s low position: 1.
