The Hammond B3 organ had a special (partly mechanical) chorus called a “scanner-vibrato”. Because it is hard to get this exact effect out of a generic chorus I thought it would be nice to have a reasonably accurate dedicated plug-in. I believe such a plug-in is already included with Logic, but that is Mac only.
So here is a first version of Martinic Scanner Vibrato. It is a simple, one trick pony kind of plug-in, although you can tweak some aspects (speed, depth, mix), and it is stereo (the original was mono).
