Pterosaur is a free synthesizer plug-in for Windows.
Pterosaur is a 16 oscillator synth. It’s loosely inspired by the classic Supersaw sound of the Roland JP-8000 in that the output of each oscillator can be independently detuned and panned, creating a very rich sound.
The basic waveform produced by the oscillators is a sawtooth wave which can be morphed into a sort of saw/pulse hybrid with the mod control.
Pterosaur for Windows (VST) is available to download at no cost.
