Little Spacey (Mac OS X, Audio Units/VST; Windows, VST) is delay effect inspired by analog "bucket brigade" that allows you to modulate the delay time for chorus or vibrato effects. Little Spacey is not restricted to mono operation, and works well in stereo or multichannel (Audio Units only) settings, offering variation of the effect between the channels.
A free demo and user manual can be downloaded from the Expert Sleepers site. The plug-in includes a number of presets (described in the manual) that show the range of possibilities that the plug-in offers.
Available immediately, Little Spacey is priced at $29 (USD, plus VAT if applicable).
