  • Page 11: A Few Words Of Thanks

    A Few Words of Thanks Thank you for purchasing the Prophet X. The Prophet X is a powerful evolution of the Prophet series. Because we’ve added a new sound engine with sample playback, you’ve got all of the synthesis capabilities and great sound you’d expect from a Prophet, but now with the infinite possibilities of samples.

  • Page 13: Chapter 1: Getting Started

    Chapter 1: Getting Started The Prophet X is an 8-voice stereo/16-voice mono, bi-timbral, hybrid digital/analog synthesizer that combines synthesis and sample playback. It has oscillators, filters, envelopes, LFOs, and other classic synthesizer components in addition to a 150 GB library of sampled instruments on its internal SSD drive.

    Using the Main Display The most frequently used controls on the Prophet X are on its front panel. But there are many additional controls (as well as numeric display of values) visible in its main display. For example, adjusting a knob or switch in the Mixer section reveals the instrument level and oscillator level parameters in the display.

    Creating a Program from Scratch An existing program can be very useful as a jumping off point for new sounds. But it’s also useful (and educational) to create a new sound from scratch. The Prophet X makes this easy by providing a “basic preset” that you can quickly recall at any time.

  • Page 43: Filter

    Filter The Filter takes the basic, raw sound of the samples and digital oscil- lators and subtracts frequencies, changing their harmonic content and the character of their sound. This change can be varied over time using the Filter Envelope to produce more dynamic, animated timbres. The Prophet X’s filter is a classic, 4-pole, resonant low-pass filter that can self- oscillate (generate a sine wave) when is set to its maximum.

This is one of the most important aspects of designing a sound.

  • Page 67: Modulation

    Modulation Although the overall sonic character of the Prophet X is determined by its samples, oscillators, and filters, much of its power to make truly unique sounds comes from creative use of modulation. Modulation is the process of routing one parameter (i.e. a control voltage) to another in order to change the way the targeted parameter behaves.

    Creating Movement with Pulse-Width Modulation Another essential technique is to use an LFO to modulate the pulse- width of the oscillator waveforms. This adds a great deal of movement and thickness and has long been used to create string pads. First, set up a simple square-wave sound.

  • Page 111: Using Sampled Instruments

    Using Sampled Instruments The internal sample library gives you a lot of variety to work with when you’re designing sounds. In some cases you may want to use the instru- ments as is, and just add effects as necessary. In other cases you may want to layer two different instruments to create something new and unexpected.

    Bypassing the Low-pass Filter on Sampled Instruments By default, sampled instrument are routed through the low-pass filter so that you can use it to shape their sound. In some cases, however, you many not want to filter an instrument so that you can sonically separate it from a second instrument, or from sounds created with the oscillators.

  • Page 115: Using The Prophet Vs Waves

    Using the Prophet VS Waves Sample Stretch is particularly useful for stretching single-cyle wave- forms across the keyboard, since they act like oscillators. You can create single-cycle waveforms out of existing samples by changing their loop size and making them as short as possible. (More on this later.) Included in the internal sample library are all of the single-cycle wave- forms from the classic Sequential Prophet VS synthesizer from the 1980s.

  • Page 117: Manipulating Samples And Loops

    Manipulating Samples and Loops Another way to create something new from an existing instrument is to edit the sample itself, by changing its sample start, end, loop attributes, or reversing it. This applies the changes to all samples in the instrument. Not all samples in the internal library are looped.

  • Page 118: Changing Sample Start And End Points And Adding A Loop

    You can smooth this transition by adjusting the loop crossfade rate. For more details, see “Creating Longer Loops” on page 104. 106 Using Sampled Instruments Dave Smith Instruments...
  • Page 119 Making a Loop into a Single-Cycle Waveform Now lets manipulate the loop and turn it into a waveform similar to the Prophet VS waveforms we worked with earlier. When you are creating loops, there are three different loop modes: Regu- lar, Pitched, and Sync.

  • Page 120: Creating "Granular-Style" Loops

    By modulating a loop’s center point, start, or end you can create some very unique and atmospheric sounds, especially if you add effects such as delay, reverb, phaser, and so on. 108 Using Sampled Instruments Dave Smith Instruments...

  • Page 121: Creating Longer Loops

    Creating Longer Loops Seamlessly looping samples requires that you find an area in the sample where the volume and harmonic content remains relatively consistent. Then you have to adjust the loop size and loop center to use that area. If the loop is too short, it can make an instrument sound static.
