Improvisation #93 for Poly Evolver Keyboard

This patch shows a bit of the caustic side of the Poly Evolver.  With the filter mostly closed, even the most metallic-sounding digital wave shapes can seem fairly soft and sweet.  But when the filter is opened – regardless of whatever help the analog side might be offering the patch – the Evolver’s famous harshness is undeniable and its reputation is shown to be well-deserved.  I don’t often wander into this sonic range of the instrument, except to create an occasional tragic but text-less tone painting.

The patch makes use of all four oscillators, pulse width modulation, and a slight amount of slow LFO-generated filter modulation which, even in the softer sections, pushes the digital oscillators slightly into their discordant timbre.
