JS80P

{See video at top of page}

JS80P is a MIDI driven, performance oriented, versatile, free and open source synthesizer VST plugin.

It comes with two oscillators (and a sub-harmonic sine), and a lot of filters, effects, envelopes, LFOs, and powerful macros to shape your sound with subtractive, additive, PWM, FM, PM, and AM synthesis, complete with polyphonic, monophonic, and split keyboard modes, MPE support, MTS-ESP tuning support, analog imperfection emulation, and more.

Features

• 64 notes polyphony.
  • MIDI Polyphonic Expression (MPE).
• Last-note priority monophonic mode. (Retrigger or smooth glide.).
• Polyphonic and monophonic hold modes to keep notes ringing without a sustain pedal.
• 2 oscillators with 14 waveforms and an additional noise generator:
  • sine.
  • sawtooth.
  • soft sawtooth.
  • inverse sawtooth.
  • soft inverse sawtooth.
  • triangle.
  • soft triangle.
  • square.
  • soft square.
  • variable pulse width:
    • pulse.
    • soft pulse.
    • bipolar pulse.
    • soft bipolar pulse.
  • custom.
• 2 filters for each oscillator, 7 filter types:
  • low-pass.
  • high-pass.
  • band-pass.
  • notch.
  • bell (peaking).
  • low-shelf.
  • high-shelf.
• Sub-harmonic sine wave for oscillator 1, distortion for oscillator 2.
• Adjustable oscillator pitch inaccuracy and instability, for analog-like liveliness and warmth.
  • Optional synchronization of inaccuracy and instability between the oscillators within each polyphonic voice.
• Microtuning support via the MTS-ESP tuning protocol by ODDSound.
• Portamento.
  • Glide from the last note or a set amount.
• Wavefolder.
• Split keyboard.
• Amplitude modulation.
• Frequency modulation.
• Phase modulation.
• Built-in effects:
  • various distortions.
  • 2 more filters.
  • basic tape simulation (saturation, tone coloring, noise, wow and flutter, slowdown stop, fast-forward).
  • chorus.
  • stereo echo (with distortion, side-chain compression or gate, and reversible delay lines).
  • stereo reverb (with distortion and side-chain compression or gate).
  • volume controls at various points of the signal chain.
• 12 DAHDSR envelopes with customizable shapes, freely assignable to most of the the oscillator, filter, and modulation parameters.
• 8 low-frequency oscillators (LFO) with optional amplitude envelope and polyphony.
  • Variable pulse width waveforms in 4 of the LFOs.
• Filter and envelope imperfection settings for analog-like feel.
• Freely assignable MIDI controllers and powerful macros.
  • Ability to override the primary function of the sustain pedal, and use it as a toggle switch for various parameters and macros.
• Channel pressure (aftertouch).
  • Optionally with semi-polyphonic aftertouch emulation (even with MIDI keyboards that don't have polyphonic aftertouch):
    • last pressed key.
    • oldest pressed key.
    • lowest pressed key.
    • or highest pressed key.
• MIDI learn.
• Logarithmic or linear scale filter cutoff frequencies.
• Tempo synchronization for envelopes, LFOs, and effects.
• Use the peak level at various points of the signal chain to control parameters:
  • oscillator 1 output.
  • oscillator 2 output.
  • volume control 1 input.
  • volume control 2 input.
  • volume control 3 input.
• Route external audio into the effects chain of JS80P (in host applications which support it).
