Martinic has announced the release of Scanner Vibrato, a virtual effect plugin that aims to recreate the scanner-vibrato effect from a well-known tonewheel organ.
It is modelled closely on the original scanner-vibrato, so it offers the same features (and flaws), perfectly preserving the character of the original effect.
However, Martinic Scanner Vibrato is more flexible; you can adjust the rate, depth, and even stereo width. And best of all, you can apply Scanner Vibrato not only to organ sounds, but also to guitar, synthesizer, or whatever sound you like.
Scanner Vibrato for Windows and Mac (32 & 64-bit VST/AU) is available for purchase for the introductory price of $19.50 USD (regular 39 USD).
