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 file import for custom scales. Standard 12-TET with adjustable A4 reference. Supports AUv3 for use in GarageBand, AUM, Cubasis, and other AUv3-compatible hosts.

About

TfxMod

This app provides a chorus and flanger audio effect plugin for mobile devices. It emulates the sound of vintage bucket brigade devices with adjustable parameters for delay, feedback, and modulation. It can be used with host applications to process audio input.

Highlights
  • Chorus and flanger effects
  • BBD-inspired delay lines
  • Adjustable delay time, feedback, and modulation
  • Variable LFO rate and waveform
  • Low-pass and high-pass filters
  • Stereo width control
Features
Read full description

TfxMod is a chorus / flanger effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). The delay line is identical to the delay line of the TfxEcho except its buffer length. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based chorus / flanger unit. Features AudioUnit Extension Chorus Effect - Delay Time: From 1 ms to 40 ms - Feedback: 0% - Modulation width: From 0 ms to +/- 1 ms Flanger Effect - Modulation Mode: mode1, mode2, and mode3 - Delay Time: From 1 ms to 20 ms (mode1&2), From 1 ms to 13 ms (mode3) - Feedback: From 0 % to 100 % - Modulation width: From 0 ms to 39 ms (mode1), From 0 ms to 19 ms (mode2), From 0 ms to 12 ms (mode3) Common - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - LFO Frequency can be synced to the tempo provided by the host application. - LFO Waveform: Continuously variable from sine wave to triangle wave. - Stereo Width: LFO Phase offset from 0 degree to 180 degree. Host Application - Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.
