Signal Perspective has recently released a free delay effect plugin for Windows and macOS. Trailbender comes with various modulation options, saturation “flavors” and other features to deliver creative delay effects.
During the last few years, I developed a VST plugin to show my students how a delay line can be tweaked to act as a mod fx, a pitch shifter, a synthesizer, and other things. With time I found myself using it in many “real world” scenarios, so I decided to release it.
The plugin is free to download in VST3 and AU formats.
