Phasex is a software synthesizer and MIDI controller designed for Linux

It can be used with ALSA MIDI connectivity interface and the Jack audio server. The synth engine is built around flexible phase modulation and flexible
oscillator/LFO sources. It is capable of various modulations, namely AM, FM, offset PM, and wave select.

It comes with various synth features that include polyphony, full parameter control via MIDI, oscillators, LFOs, ADSR envelope generators, chorus and stereo crossover delay effects and it can process audio input from other audio sources via /Jack.
