Blue Synth PM is a free phase modulation virtual synthesizer. It can produce lush pads or powerful leads. It is available either as a standalone application or as VSTi for using in a host application such as Sonar, Cubase, Ableton, etc.
There are two oscillators to create the carrier waves which can both be phase modulated by a sine wave. You can choose the carrier waveform and apply an attack, decay, sustain and release envelope whose amount can be adjusted. The Freq PM knobs control the phase modulation frequency, 0 is no modulation 1 is full modulation at half sampling rate. Oscillator 2 can be detuned. The output can be fed through two filter banks with cutoff, resonance and track as well as ADSRs affecting the filters. Programs can be saved. There are 10 factory sounds preloaded in the synth courtesy of Yoa out of the 20 available program slots in each program bank. Programs/banks can be saved as text files or as fxp/fxb files using the host program for VSTi. Please set MIDI and audio preferences in standalone version first. In the VSTi the host settings fixes these parameters.
The download is free. All I ask is for feedback and ideas for additions or modifications. Also additional programs/banks welcome. I will host on my site.
