DuoTone: A Unique multi-channel approach to effects.

Each DuoTone plugin uses our unique approach to audio routing to give you a whole new way of working with effects. DuoTone effects share a common approach to audio routing, so when you learn how to use one plugin then you’ve learned them all. Each DuoTone plugin takes the in-bound audio, applies a volume control and then splits the audio signal into three separate paths: the A Channel, the B Channel and the Dry Channel

The Dry channel is just that – no effect applied, but you can add a fixed delay (for those double-tracking effects) and its own volume(gain) control.

The A Channel and the B Channel have similar layouts, each starts with a parametric eq, with unlimited nodes, that allows you to shape the inbound signal to your liking before it enters the effect, then comes the effect itself – with all the controls you will ever need – followed by a pan control and an independent gain control.

Series or Parallel. DuoTone effects allow you to set up in series or parallel. In parallel the inbound audio is routed to both the A Channel and the B Channel at the same time. In series, the B Channel is turned off, and a second independent duplicate effect is inserted into the A Channel, the C Effect, so you get two effects (A and C) one after the other each with separate independent configurations.

Finally the signals are combined onto the output section where again you can set the stereo width and overall gain. This set up allows you to get subtle or drastic audio effects quickly and easily. DuoTone effects come with a preset system – with a small set of presets to get you started – so you can keep your preferred layout across all your projects.

DuoTone Phaser

The DuoTone Phaser is the effect that started this whole process for us, we wanted our own take on those Bi-tone phaser effects. The two independent phasers allow you  to get exactly the sound you want: Each effect has Frequency 1, Frequency 2, Feedback, Mix, Depth and Speed.


DuoTone products ship as Windows 64-bit VST3 and MacOS VST3 and AU plug-ins.
