This is a feature of Buchla 359 (see comment at top of)
http://rubidium.dyndns.org/~magnus/synths/companies/buchla/Buchla_2590_2_200.jpg

The 300 series is really the 200 series with added digital control. One 
feature you can get with that is auto-tune. The 259 in itself does not 
contain it, just some feature that makes it easier to implement in a 300 
series context.

Cheers,
