In Depth

Take Control When You Need It

At Relayer's core is a variable multi-tap engine, providing up to 32 delay lines. Delay times are initially set with a typical free or host-synced time parameter and then modulated by swing and warp controls, allowing for quick and easy bouncing ball-style effects. By clicking through the central tabs, Relayer reveals a number of per-tap modulation editors for an unprecedented level of control and flexibility. Explore and experiment with each section as you need it, exercising precise control over time, gain, pan and 2 variable multi-effect units. Freely draw sequences for each parameter or use the built-in presets and listen as your sound modulates over time, then tweak and transform to taste.

On Stage and in the Studio

Relayer functions exceptionally well in both studio and live settings. A playable Input Gate allows you to feed the delay with signal momentarily, perfect for adding dub-outs, builds or deconstructions to your performances or applying delay to specific lyrics with ease and precision. Master low and high-cut filters along with discrete wet and dry controls provide many creative mixing options, and even at high repeat values Relayer provides rock-solid and CPU efficient performance making it a reliable force in the most demanding environments.

Natural-Born Shifter

In addition to the two multi-effect units, Relayer includes a unique Color section that can process your sound through a wide range of custom, high-quality IRs. Choose from a variety of dedicated instrument amps, discrete effect amplifiers or lo-fi devices like hand-held radios, laptop speakers or telephones to immediately change the character of your sound. The effect can range from adding a subtle layer of dirt to a complete and dramatic alteration of the perceived sound source.
