FREE: Acid Zone Retro Synthesizer VST by SonicXTC

ACID Zone Retro Free VST Plugin

SonicXTC releases Acid Zone Retro, a free download Vintage Synthesizer VST for Windows. This freeware plugin is a monophonic single oscillator synthesizer, that is designed to harken back to the DIY analog synths of the past. AZR-01 has all the synthesis programming parameters available on the front panel. It comes with 32 presets to get a user started.

New freeware 5 oscillator synthesizer, Trance Zone Retro LE, is a recreation of those old classic synthesizers that brought the “Super Saw” sound to the dance floor. Like Deep Mono, Deep Step-606, and AZR-01, TZR-01 is simple to program and has all the synth programming parameters on the front panel. Tweak a knob and you immediately begin to sculpt the sound. It comes with 16 presets to get you started down the Super Saw path!

The sequencer included in AZR-01 was derived from reviewing the many sequencer schematics available on the open Flowstone/Synthmaker community forum. We made our own proprietary modifications, but wish to thank all the developers for sharing their groundbreaking work.
