Firefly Synth is a semi-modular software synthesizer and fx plugin. It’s basically InfernalSynth’s big brother.
Features:
Theming support.
Global unison
Stereo spread + voice detune.
LFO and oscillator phase offset.
LFO and envelope “detuning”.
5 oscillators
Noise generator.
Karplus-strong generator with 2 modes.
Sine + bandlimited saw / triangle / square + pwm.
Bandlimited DSF (Discrete Summation Formulae):
this is basically a limited additive generator, see https://www.verklagekasper.de/synths/dsfsynthesis/dsfsynthesis.html
Hard-sync, unison, AM and FM support.
10 per-voice and 10 global effect modules
Resonant state variable filter with low/high/band/allpass, notch, peaking eq, low/high shelving and bell filters.
Comb filter with feed-forward and feed-back gain.
Distortion module with waveshaper, resonant LPF and before-and-after shape skewing parameters, hard clip and a couple of soft clipping / saturation functions.
(Global only) reverb module, feedback delay and multi-tap delay.
10 per-voice and 10 global LFO’s
Optional bpm-sync and one-shot modes.
Smooth noise, static noise, free-running static noise and various periodic waveforms.
Horizontal and vertical skewing parameters.
Phase adjustment, stair-stepping and smoothing parameter.
10 per-voice DAHDSR envelopes
Linear and 3 exponential modes.
Optional bpm-sync and smoothing parameter.
Attack/decay/release slope control.
Regular legato + retrigger/multitrigger options for monophonic mode.
Master CV module
MIDI/BPM smoothing controls.
5 freely-assignable aux parameters to be used through the mod matrices.
MIDI-linked pitchbend and modwheel (these are bound to external MIDI).
Voice input module
Poly/monophonic mode.
Portamento mode with optional bpm-sync.
Routing matrices
Osc-to-osc amplitude-modulation and frequency-modulation.
Per-voice and global audio routing between osc/voice-mixdown/fx/master-out.
Per-voice and global cv-to-audio matrices (envelopes/lfos/master cv/midi/note events to osc and fx parameters and audio-to-audio matrix parameters).
Per-voice and global cv-to-cv matrices (midi/master cv/envelope/LFO to envelope/LFO and cv-to-audio matrix).
For per-voice modulation, on-note versions of all global CV sources.
