Poly-850 is a MP3 & Audio software developed by Synapse Audio Software. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Poly-850:
Brothersoft Editor: The Poly-850 is a VSTi / DXi synthesizer plug-in, which started out as an emulation of a vintage synth, but went beyond that by adding a several improvements and new features over the original.
Additionally, automation and a redesigned user interface with Direct Access to every parameter, make it much more user friendly and accessible, than the original unit.
The concept of the Poly-850 is simple: 2 oscillators, one filter for all voices, 3 envelopes, a modulation generator and a chorus effect.
What makes the Poly-850 special, is the unique sound of the oscillators, and the quality of the chorus effect.
As a result, the Poly-850 is particularly great for warm backing sounds and atmospheric pad sounds, that fit nicely into the background of a mix. However you'll find all kind of other useful sounds in the preset banks as well.
