My ANCIENT kn6000 has a "Girls Doo Wah" voice among others ... I have never used it ... plus, I've never taken the time to figure out when the 'Doo' changes to 'Wah' or vice versa ... there is also a 'Bob's Scat' voice which I have used on occasion in unison with a jazz flute or jazz guitar voice on tunes like "Blue Bossa", "Summer Samba", etc. ... but never for more than one time through the tune ...
