HY-Poly is a polyphonic subtractive synthesizer with an intuitive modulation process. The synthesizer is equipped with two oscillators with vibrato and sync, an auxiliary oscillator, a noise generator, two multi-mode filters (low pass, high pass and band pass), four envelopes, double LFOs, S&H, three sequencers, and a trio of effects (delay, chorus and utility effect) … The main oscillators can be freely changed between sawtooth and pulse waveforms with adjustable pulse width.
The oscillator section also includes an optional third oscillator and modulation oscillator that supports FM, ring modulation, and FM feedback. There’s a MIDI FX section, and it adds numerous goodies like the insanely flexible arpeggiator, MIDI harmony, note echo, velocity instruments, and more. The audio FX section has over twenty additional effects. There are also macro controls for setting multiple parameters at the same time.
