Space Age 555

Audiority's Space Age 555 is a meticulously modeled emulation of the Roland Chorus Echo RE-501/SRE-555, the larger-format sibling to Roland's legendary Space Echo. Released in the late 1970s, the hardware unit combined tape delay, BBD chorus, and spring reverb in a single rackmount format, and this plugin captures that integrated signal chain with considerable fidelity.

The core appeal lies in its layered approach to ambience. The tape echo section models six distinct modes with adjustable head configuration, internal compander characteristics, and motorspeed controls that influence flutter and wow. The BBD chorus circuit adds shimmer without obvious digital artifacts, while the spring reverb contributes the unit's signature lush, slightly brittle character. Unlike many reverb plugins that aim for pristine decay, the spring section retains the compact, slightly metallic resonance of actual spring tank design.

Audiority preserved the original hardware's "fake stereo" output architecture, where different sections route to left and right channels for a naturally uneven spatial image. This quirk, rather than a limitation, has become a signature sonic marker of the RE-501 in professional recordings across funk, soul, and ambient genres. Additional parameters for noise floor, feedback control, and tempo sync enhance the plugin's flexibility beyond the original hardware's capabilities.

The Space Age 555 is best suited for producers and mix engineers seeking cohesive, period-correct vintage ambience without resorting to multiple separate processors. Its three-in-one architecture encourages integrated sound design rather than layered effects chains, making it particularly valuable for adding organic depth to rhythm sections or lead instruments with minimal CPU overhead.
