Synthmagic and Tronsonic have announced the release of J4, a virtual Roland Jupiter 4 instrument library for Native Instruments Kontakt.

Inspired by a legendary 4 voice Japanese analogue synthesizer from the late 1970s, ‘J4’ also includes an extremely comprehensive sequencer.

‘J4’ features 2 different sets of samples – one set recorded ‘DI’, with a NEVE style pre-amp/eq and boutique valve mixer at 48khz/24 bit. The second set uses the same method, but has also been recorded to brand new ‘old-stock’ tape at 15ips on a Studer A807 quarter inch reel-to-reel recorder.

J4 features

  • Single Oscillator Analogue style synth with 6 Waveforms, a Sub Square Wave Oscillator and Noise Generator.
  • Over 320 presets.
  • 2 different sample sets (one DI, one taped).
  • Syncable 16 step sequencer system with Filter, Resonance, Velocity and Chord sequencer.
  • Syncable Arpeggiator.
  • Syncable main LFO and VCF S/H LFO.
  • Overdrive function via relationship between ‘Volume’ and ‘Level’ controls.
  • Sub LFO.
  • Dual Polarity Keytrack.
  • Unison, Portamento and Mono mode.
  • 4 Voice or Full Polyphony.
  • Pitch Bend and Mod Wheel routing system.
