PolyGAS (Polyphonic Granular Advanced Synthesizer) is a free virtual synthesizer based on a granular method of sound synthesis.

Main features:

  • 32-part polyphony.
  • Support of files of samples in the WAV and AIFF formats, digit capacity of 8,16,24 and 32-bits / sample, mono / stereo. Files are supported only uncompressed by codecs.
  • The editor of the bending parameters of granular synthesis. 18 envelopes with the maximum quantity of nodes - 40 (in each envelope). Also there is a tab where it is possible to edit dependence of amplitude of the clicked key bending from a tonality. There is a possibility of synchronization of provisional regulations of nodes of envelopes with rate of composition in DAW.
  • Controlled randomization of parameters of granular synthesis.
  • Amplitude non-linear distortions, with a possibility of a type selection (a clipping, bit-crusher, etc.) - only 11 types.
  • The controlled universal filter allowing as manual installation of frequency of a cutoff (Cutoff) and a resonance (Reson), and by means of envelopes. There is a mode in case of which the frequency of a cutoff depends on a tonality of the clicked key. In the filter different types of filtering (LP, HP, BP, Comb and Allpass), only 11 types are used.

I am using PolyGAS64.dll in Reaper and have discoved a serious bug. Whenever I choose the distortion type 'Hump', after about 1 second of ugly noise, the audio output becomes silent and the plugin stops working. I have to reload it onto the track to get it working again.

Also, I have a question: Where are the sample files (.WAV) stored? Whichever sample filename is displayed on the UI, when I click the sample folder icon, all I see is <default.wav> in this location: C:\Program Files\VSTPlugins\Stone-Voices.ru\PolyGAS\data. For example, the first preset uses a sample called <vibes.wav>. Where is this file located?
