Strymon StarLab- Time-Warped Reverberator Eurorack Module

What is StarLab?

Development for StarLab began with one goal in mind: to provide the highest quality reverb possible for modular systems, perfectly tuned for immersive electronic soundscapes with a high degree of flexibility and creative control.

The seemingly simple idea of allowing the pre-delay signal to be fed directly to the module’s output led to the development of rich sounding delay, chorus, and flanger effects, all of which can be used together with or independent of the reverb.

While experimenting with short delay times using feedback and filtering, we began finding very musical and expressive Karplus-Strong string synthesis sounds, and realized that StarLab could move beyond signal processing and become a truly unique voice module as well.

All this ultimately resulted in the creation of a module that is equal parts reverb, delay/modulation, and playable instrument.

Choose Your Character.

StarLab gives you three distinct Reverb textures to choose from: Sparse, Dense, and Diffuse.

The Sparse reverb creates reflections that are far enough apart from each other to be audibly distinct. Legato notes create a lush but pleasingly clean sound field, while staccato notes reveal individual echoes in a way that is well suited for sound design and special effects.

The Dense reverb texture is an immediate-response reverb with a smooth sound field, featuring sonic characteristics similar to a plate. This texture is well-suited for applications ranging from small space ambience all the way to large cavernous reverbs.

The Diffuse reverb creates a slow-building, atmospheric wash that excels at ambient, swell, and even reverse-like textures. The Diffuse reverb deconstructs and spreads transients over time to achieve its bloom-like effect.

Over and Over Again.

StarLab’s Delay section is actually a vastly expanded reverb pre-delay.

When used as a reverb pre-delay, delay FEEDBACK is still available, allowing for the creation of even longer reverb decays, while the ability to modulate the pre-delay time allows even further creative possibilities.

Press the ECHO ON button, and now you can create a wide variety of classic delay and delay-reverb effects.

Echoes can be synced to an external clock with the DELAY/TUNE knob acting as a clock multiplier/divider for the echo repeats. Delay time can also be set by tapping a tempo using the TAP/TRIG button

Modular Modulation.

StarLab provides a wide range of modulation effects to add fatness and movement to your sound, all available on their own or in addition to StarLab’s reverb.

The short-delay portion of the DELAY/TUNE knob is tapered to make it easy to dial in a variety of rich chorus and swirling flanger effects when modulated by StarLab’s internal LFO. Use the dedicated FEEDBACK knob to add resonance and musical harmonic sweeps to flanger effects. Make your oscillators sound huge with lush, shimmering organic chorus. Set the DRY level to minimum for classic vibrato effects.

Moving Targets.

StarLab’s LFO features triangle, square, ramp, saw, random, and envelope waveforms that can be used to modulate your choice of three targets:

Send the LFO signal to the delay section for modulated echo effects or for modulated pre-delay signal within the reverb. You can also create classic modulation effects such as flanger, chorus, and vibrato. In Karplus-Strong mode, the string tuning is modulated.

Send the LFO signal to modulate the SIZE / PITCH (process rate) of the reverb core for effects ranging from mild to wild and even on to music-generating: In Quantize mode, signal from the LFO will be quantized to any of 15 different scales as it modulates the SIZE / PITCH parameter.

Or send the LFO to the filter for a variety of effects. Activate the 24dB/oct low pass filter for classic filter mod effects, or achieve more subtle filter modulation of the reverb’s HIGH DAMP. In Karplus-Strong mode, modulating the HIGH DAMP parameter creates lifelike dynamic string damping.

When clocked externally via CV, the LFO SPEED knob becomes a clock multiplier/divider. You can also connect an external LFO or function generator to StarLab’s EXT LFO IN and direct that signal with StarLab’s Target switch, controlling amplitude with the DEPTH knob.

Dynamic String Synthesis.

In Karplus-Strong mode, StarLab becomes a delay-based CV-tunable monophonic string synthesis voice module with a uniquely musical character.

Press the TAP/TRIG button to pluck the string, or hold the TAP/TRIG button to bow the string.

Using StarLabs CV inputs, it is possible to alternate plucking and bowing, while CV control of the HIGH DAMP parameter creates lifelike dynamic string damping.

This string voice can be processed through StarLab’s reverb to create a mesmerizing variety of sounds.

It is also possible to feed an input into the Karplus-Strong circuit and vibrate the string with an external drum sound or other audio signal to create tuned resonances and interesting evolving harmonics.
