Ugo Audio released Rez 3, a free VST instrument plugin for Windows, loaded with 24 presets. Additional sounds are available as 3 commercial banks, each of it containing 128 presets.
Rez is a seemingly basic synth, but it’s capable of a very wide range of sounds. While Rez has a bunch of cool features, the beating heart of Rez is its filter. It’s made from multiple chained filters acting as a single powerful filter and it’s highly resonant, providing Rez with its distinctive character. Top that off with distortion, a phaser, various oscillator modulations, delay, and a killer programmable arp and step sequencer, and you’ve got a powerhouse of a synth in a very small package.
