It’s only a few months since the release of the Lore Reverse Soundscape Generator, but Walrus Audio is back with another ambience pedal that shares exactly the same format with an identical set of controls. 

This time, however, what you’re getting is a ‘Granular Soundscape Generator’ based on the digital processing technique of micro-sampling, where short samples called grains are read from a delay buffer and can then be manipulated in a number of ways to achieve a range of effects.

Utilising two onboard DSP chips, the signal runs through two separate effects in series, the Feedback and Regen knobs providing feedback paths for each, and there are five different selectable granular delay programs.

Program 1 offers Reverse Delay into a Reverse Granular algorithm that plays grains backwards. Basically, before engaging either feedback path, you get a load of glitchy repeats, their timing set with the Time knob or tap tempo. These can be completely transformed from woolly to glassy via the Tone knob, which incorporates both low- and high-pass filtering. 

Advancing the Feedback and Regen knobs lengthens and extends the trail, so you get a whole long-lingering murmuration of shifting and pulsating ambience going on. To this you can also add modulation (with adjustable rate and depth) for an even more complex stew. 

This mode alone has so much variation on the theme to get engrossed in – including the X knob for adjusting grain size – that it may be some time before you try the other four: Forward Delay into Octave Up Granular; Analog Delay into Octave Down Granular; Multi-Tap Granular into Multi-Tap Granular (Grain-Verb); and Forward Delay into Randomized Pitch Granular.

All of those, though, are sufficiently different to warrant their inclusion in the pedal and are ripe for sonic exploration with a heady cascading mix of delay, pitch shift, modulation and glitchiness.
