Phosphor 3

Glow in the dark synthesis.

Phosphor 3 is a dual-oscillator additive synthesizer that puts the raw building blocks of sound at your fingertips. Draw, randomize, or select up
to 64 harmonics per oscillator, then shape them with envelopes, LFOs, cross-modulation, and a flexible mod matrix. Originally inspired by the
alphaSyntauri, a rare digital additive synth from the early 1980s, Phosphor 3 takes that concept far beyond its origins with modern MPE
expression, polyphonic modulation, and a full effects engine.

Additive Oscillators

Two identical additive oscillators, each with up to 64 individually editable harmonics. Start from classic shapes: sawtooth, triangle, square,
or draw your own harmonic spectrum directly in the partial editor. The intelligent randomizer generates musically useful timbres with variable
rolloff, density, and formant peaks, so every click produces something worth exploring. Choose 16, 32, or 64 partials per oscillator to balance
complexity against CPU. Each oscillator has independent level, pan, transpose, fine tune, a noise generator with lo-fi downsampling, and
cross-modulation (FM) for pushing timbres into harsher, more complex territory.

Modulation

Two ADSR envelopes with adjustable attack, decay, and release curves. Two LFOs with four waveforms (pulse, sine, saw, random), tempo sync, and
the option to run polyphonically, a separate LFO per voice, or globally. An 8-source modulation matrix routes velocity, pressure, pitch bend,
mod wheel, CC 74, triggered random, and both LFOs to destinations across the oscillators and effects.

Effects

Stereo delay with independent left/right time, feedback, and cross-channel feedback for ping-pong and rhythmic patterns. Tempo sync locks delay
times to your DAW. Dual band-pass filters after the delay let you carve the wet signal into resonant, frequency-specific textures.

Expression

Full MPE support with per-note pitch bend, pressure, and slide across 16 polyphonic voices. Mono legato and mono retrigger modes with adjustable
portamento. Unison mode for thick, detuned stacks. A scrollable 128-key on-screen keyboard with velocity from touch position, pitch bend from
horizontal drag, and channel pressure from vertical drag, no hardware controller required.

Tuning

MTS-ESP client support for real-time microtuning from any MTS-ESP master. TUN
