Undulator is a celebrated modulated tremolo effect from Eventide, known for its origins in the iconic H3000 effects processor. This unique effect offers a blend of ethereal feedback and detuned echoes, all powered by AM / FM modulation. It is an excellent tool for both creative musicians and audio producers looking to manipulate samples or add movement to instruments like strings, pads, guitars, and keys. Adding Undulator to your plugin collection means you have one of the most playable tremolo-style effects available for your DAW or iOS device.

With Undulator, you can easily create evolving pads, sync’d chops, and dreamy soundscapes. It works seamlessly with a multi-tap delay, enhancing the depth and character of your sound. The controls in Undulator allow any audio to sustain and be shaped effectively. This feature is ideal for transforming ordinary synths, keys, guitars, or even vocals into evolving pads or tempo synced production elements. Additionally, it can produce ethereal and fluctuant delays, making shorter sounds longer and layered effects richer.

One standout feature is the Ribbon, which lets you morph tremolo patterns into vacillating rhythmic territories. This component is perfect for highlighting synth pads, generating a sense of flux that can be difficult to achieve through traditional means.

By turning up the MIX, you can adjust the dry/effect ratio to fine-tune the balance between the original sound and the effect. Undulator also offers multiple modulation waveform shapes, allowing you to modify the rhythmic feel of your sound. You can finesse the detuning of delays by using SPREAD, enhancing your creative possibilities.

Undulator is equipped with a secondary LFO that controls how fast the depth and speed modulation “wiggle” their targets. You can lock the tremolo to tempo using the SYNC function, ensuring everything stays in rhythm. Using the RETRIG option at the top of the waveform creates a more predictable effect that can be useful in various compositions.

The Ribbon offers dynamic control, letting you ‘play’ with the effect in real-time. This fluid control adds a layer of creativity to your sound design, enabling effortless transitions between your custom settings. The SLOW/FAST button toggles a “Slow LFO” mode, and holding it down activates BRAKE mode, which temporarily slows down the LFOs at a constant rate until you release it.

You can easily update the tremolo speed in real-time using the TAP button, adding further flexibility to your performance. Undulator is available as both an AUv3 plug-in and a Standalone App, providing versatility in how you choose to use it.

In summary, Undulator brings a wealth of options for shaping sound, perfect for those wanting to craft unique musical expressions. Whether you're creating layered effects, enhancing rhythmic character, or using feedback accentuation, Undulator is an essential tool for any creative musician. With its rich features in one app, it's a valuable addition to your audio toolkit.
