Roland JX-3P - Features

Features

The JX-3P is a six-note polyphonic, 61 key synthesizer with sawtooth, 50 and 10% pulse waveforms, and a noise generator. It has 32 factory programs in ROM, and user memory for 32 programs.

The JX-3P also features a built-in 128-step polyphonic built-in sequencer that can be synchronized to external devices (such as drum machines) connected to its simple clock voltage input jack. The sequencer cannot synchronize using MIDI.

Its architecture is similar than the Juno series synths produced around the same time. Both machines employ the same interval-timer DCO technology, have a single software-generated ADSR envelope generator, use the Roland IR3109 low-pass filter, a discrete VCA, and have an on-board stereo chorus effect.

The Juno line had only a single DCO (with sub-oscillator) per voice, while the JX-3P had two distinct DCOs with detuning and several cross-modulation modes. Also unlike the Juno, the JX-3P allows the pitch of either oscillator to be controlled by its envelope generator. The Juno's features not included with the JX-3P were pulse width modulation and a second chorus mode.

Famous quotes containing the word features:

    “It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.”
    Robert Frost (1874–1963)

    Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.
    Henry David Thoreau (1817–1862)

    However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.
    Andrew Jackson (1767–1845)
