arcDev Noise Industries has released ET-301, a free delay effect plug-in for Windows.
New version should fix all memory-leak probs, and also work fine with multithreading hosts (does here, anyway). Not preset-compatible with earlier versions. PC-only.
Some extra goodies, too, but same basic sound as the original.
arcDev ET-301 is available to download as a freeware VST effect plug-in for Windows.
