Scanner Vibrato is a virtual effect plug-in that aims to recreate the scanner-vibrato effect from a well-known tonewheel organ.
The Scanner Vibrato is also available as part of the Retro Pack, a collection of Martinic's grooviest instruments and effects with a bundle discount.
If you would like instructions for this plug-in, you can browse through the manual page.
Martinic Scanner Vibrato 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, 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.
