  • Page 9: Thank You

    Prophet vibe. There’s something magical about the combination of a digital front end followed with analog filters and electronics per voice. The Prophet 12 has a sound, a soul of its own, unlike any other instrument. I love it! I hope you enjoy playing this instrument as much as we enjoyed designing it.

  • Page 11: Overview

    Half the programs are in four Factory banks and the rest are in four User banks. When a Prophet 12 leaves the factory, the User banks are an exact copy of the Factory banks. Program 1 in bank 1 of the User banks is the same as program 1 in bank 1 of the Factory banks, User program 2 is the same as Factory program 2, and so on.

  • Page 12: Using The Display And "Soft" Controls

    Using the Display and “Soft” Controls The Prophet 12’s more performance-oriented parameters are all acces- sible via dedicated knobs and switches on the front panel, but there are even more parameters available via the OLED display. For example, there are fifteen knobs and switches in the Oscillator section.

You’ll also find information about MIDI setup to more effectively integrate the Prophet 12 into your rig, as well as information about using a footswitch and expression pedals. Also, look for the tips and notes scattered throughout the manual to gain a better working knowledge of the instrument.

  • Page 22: Oscillators

    Oscillators The Prophet 12 has four oscillators for each of its twelve voices. The oscillators are capable of generating the “classic” analog wave shapes— sine, triangle, sawtooth, square—as well as more complex shapes and different types of noise. Use the four oscillator buttons to select an oscillator for editing. The mysterious ring that connects the buttons is not a life preserver.

  • Page 28: Low-Pass Filter

    Low-Pass Filter The Prophet 12 features one analog resonant low-pass filter per voice. The filter is switchable between 2- and 4-pole modes and has a dedi- cated five-stage (delay/attack/decay/sustain/release) envelope generator, capable of looping the delay, attack, and decay segments. There are also controls for modulating the filter cutoff with the keyboard and envelope amount with keyboard velocity.

  • Page 35: Delay

    Delay The Prophet 12 has a stereo, four-tap digital delay per voice. It can be used for simple delays or, in conjunction with modulation and short delay times, flanging and chorus effects. Simple reverbs can be built using different delay times and settings on the level and feedback of all four delays.

  • Page 36: Reverb And Modulation-Based Effects

    Use a triangle wave LFO to modulate the delay time, being careful to keep the LFO Amount low so that it doesn’t drive the delay time to zero and “flatten out” the triangle at one extreme. It will be fairly obvious when that happens. Delay Dave Smith Instruments...
  • Page 37 DC routed to Delay Pan (in the modulation matrix) will place the ping-pong in the desired position in the stereo field. Both the LFO and the Delay must have Sync on, and the LFO should also have Wave Reset on, to keep everything in sync. Prophet 12 Operation Manual Delay...

  • Page 38: Low Frequency Oscillators

    Low Frequency Oscillators The Prophet 12 has four low frequency oscillators (LFOs) per voice. The LFOs can be free-running, reset by keystrokes, or synced to the arpeggia- tor and MIDI clock. Press any of the four LFO buttons to choose an LFO for editing.

  • Page 41: Auxiliary Envelopes

    Auxiliary Envelopes The Prophet 12 has four, five-stage envelope generators. Two of them are dedicated to the low-pass filter and VCA, but the other two can be routed to any of the modulation destinations. Actually, any of the envelopes can be routed to any destina- Note: tion—or multiple destinations—using the modulation matrix.

  • Page 42: Modulation

    Using the Assign Mod Buttons The Prophet 12 provides a shortcut for modulation routing in the form of the Assign Mod Source and Assign Mod Destination buttons. To assign modulation: 1.

    5. Use either the a knob or soft knob 3 to set the modulation moUnt amount. New modulation paths can easily be assigned by repeating these steps until all of the available mod slots are used. Prophet 12 Operation Manual Modulation...

  • Page 44: Distortion

    Distortion The Prophet 12’s stereo analog distortion is actually two stereo distor- tions, one for layer A and another for layer B, so that split and stacked sounds can have different distortion settings per layer. —Sets the distortion amount for the current layer.

  • Page 45: Unison

    Unison When U is on, the Prophet 12 plays like a monophonic synthesizer. nison That is, only one note can be played at a time. Turn U on to display nison the three parameters that control how the voices and keyboard will respond.

  • Page 46: Glide

    When played polyphonically, the Prophet 12 behaves in a similar fashion, except the pitch glides up or down from the previous note played on that voice.

  • Page 47: Hold

    When used in conjunction with the arpeggiator’s Arp Auto Latch function, arpeggiated notes are latched on and replaced by any new note(s) struck. Prophet 12 Operation Manual Hold...

  • Page 48: Arpeggiator

    Arpeggiator The Prophet 12 has a flexible and full-featured arpeggiator that can be synced to the LFOs, delay, and external MIDI clock. Particularly complex arpeggios can be created using split and stack with different arpeggiator settings for layers A and B.

  • Page 50: Master Volume/Voice Volume

    Voice Volume is set in the Vol/Dist tab of the VCA screens. Voice Volume is programmable to balance the level between programs. The volume settings in the Layers screen are Voice Volume. Note: See Layers, Split, and Stack on page 43 for more information. Master Volume/Voice Volume Dave Smith Instruments...

  • Page 51: Pitch And Modulation Wheels

    Pitch and Modulation Wheels The Prophet 12 has a spring loaded pitch wheel and a modulation (mod) wheel. The pitch wheel range can be set separately for bending up and down. To set the pitch bend range: 1. Hold s and move the pitch wheel.

  • Page 52: Touch Sliders

    Touch Sliders The Prophet 12 has two position- and pressure-sensitive touch sliders. That is, each of the sliders serves as two modulation sources, the values of which are determined by finger position and finger pressure. Those sources appear in the modulation matrix as Slider 1 Position, Slider 2 position, Slider 1 Pressure, and Slider 2 Pressure.

  • Page 53: Layers, Split, And Stack

    Layers, Split, and Stack Each of the Prophet 12’s programs contains two layers, layer A and layer B. Each layer can contain a complete, distinctly different sound from the other layer. In a sense, each program is really two programs. This helps to facilitate split and stacked (layered) key mapping.
  • Page 54 I . Load A/B (soft key 4): These operations manage the sounds loaded into the Important: current program’s A and B layers, but the program must still be writ- ten to memory in order to retain those settings. Layers, Split, and Stack Dave Smith Instruments...
