Design
Like the original Minimoog, the Voyager has six sound sources. Five of these (three voltage-controlled oscillators with switchable waveforms, a noise generator, and an external line input) pass to a mixer with independent level controls. The mixed output of the sources is then passed through the voltage-controlled filter and a voltage-controlled amplifier, each of which has its own ADSR (Attack-Decay-Sustain-Release) envelope generator . The voltage-controlled filter can itself be made to oscillate, thus comprising the Voyager's sixth sound source.
In addition to similar features of the original Minimoog, the Voyager was designed to have a memory bank capable of storing 128 presets, a touch pad modulation control, dedicated Low-frequency oscillator(LFO), two modulation busses (one controllable via the modulation wheel and the other with a foot pedal), two ADSR envelopes for filter and amplifier control, a pressure-sensitive keyboard, 14 voltage-control inputs, and MIDI(Musical Instrument Digital Interface) input/output.
Unlike the original Minimoog, the Voyager's modulation busses can be set to affect almost any parameter of the sound, not just the filters. Although the synthesizer features MIDI control and advanced patch storage, all audio paths in the Voyager are analog with the sound originating from any of three oscillators designed for high tuning stability, as the original Minimoog oscillators tended to slightly shift out of tune while playing.
With the Voyager, certain parameters that were fixed on the original Minimoog can be programmed to suit the player's preference. This includes selection between low-note, high-note or last-note priority. Also, the envelope generators can be set to re-trigger with each pressed note or they can be set not to re-trigger until all notes are lifted and the next note is played.

Famous quotes containing the word design:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
