ROLAND JUPITER 4 - Sounds, Patches & Presets | Synth Demo


"Roland Jupiter-4 analog synthesizer demo, featuring some sounds, patches and presets. This Roland Jupiter 4 synth demo showcases some pads, S&H patches, LFO tweaking, filter resonance, and envelopes. Filmed at Vintage Synth Museum in Oakland, CA.

Manufactured from 1978 to 1981, the Roland Jupiter-4 was Roland's first polyphonic synthesizer and supported programmable memories and voice assignment modes. It features 49 keys, 4 voices of polyphony, 1 VCO (triangle, square, square with PWM) + 1 sub per voice, 1 LFO (triangle/square/sawtooth/reverse sawtooth), a resonant lowpass and resonant highpass filter, 2 ADSR envelopes for VCF and VCA, built-in ensemble/chorus effect and arpeggiator.

The Roland Jupiter-4's LFO is routable to oscillator pitch, pulse width, filter cutoff and amplifier and can reach audio frequencies, allowing for crude FM and AM synthesis. The Jupiter 4's arpeggiator provides a choice of up, down, up/down, or random mode, and there is also polyphonic portamento/glide on-board which can be used in conjunction with the arp. Ten presets and 8 user memory slots allow you to create and save your own sounds and patches.

The Roland Jupiter-4 is known for producing rough and raw sounds, big low-end bass, crazy fast LFO metallic timbres, and gritty resonance. In this Roland Jupiter-4 demo I tried to show a few of these types of sounds during my brief time with it. The Roland Jupiter-4 often commands high prices on the second-hand market these days."
