[sdiy] Scanner Vibrato emulation, first results

[jhaible]

Ok, I have no idea if this is close to the original or not,
but at least I think it's better than the Korg BX-3's
Chorus/Vibrato which I've been using so far.

Here are some results, straight from the breadboard:

http://www.oldcrows.net/~jhaible/mp3/scanner_vibrato/

Short *.mp3 samples for an organ chord (old CX-3: no Hammond)

dry, C1, C2, C3, V1, V2, V3

and longer sample with an OB-8 pad sounds thru C3 mode
(gives some hint that with several scanners this could possibly
be expanded to a Solina-style triple chorus)

and a longer sample with a held OB-8 chord and variable
scanning rate - what your Hammond normally doesn't.

Comments welcome - tell me how to further improove it.
