X-Poly is a synthesizer plug-in which started out as an emulation of a vintage synth, but went beyond that by adding many improvements and new features over the original.

The concept of the X-Poly is based around two oscillators, each containing four special sub-oscillators spaced one octave apart. Both oscillators can be blended seamlessly between a square and a sawtooth-type waveform and can be freely panned in the stereo field. The six-stage envelopes controlling the amplitudes of the oscillators provide a linear slope for the first five stages and a semi-logarithmic release for the final stage.

A global filter applied to all voices simultaneously as well as a stereo noise generator and a sophisticated chorus effect complement the unique sound of this instrument plug-in. As a result, the X-Poly is particularly great for warm backing sounds, leads and atmospheric pad sounds, that fit nicely into the mix.
