Practically, yes. Malcolm Cecil has been working on a touring version of TONTO (basically a "virtual TONTO") and that module would handle a lot of the work. In fact, Cecil featured the virtual TONTO at a music festival in the UK earlier this year.
Cecil and Margouleff started with a Moog Series III, then added two more, and kept adding patch bays, modules etc. until they had a mutli-performer polyphonic unit. Due to circuits heating, pitches were constantly shifting, which made recording TONTO a very...interesting task.
They recorded several albums with TONTO, the first being Zero Time. This album also features their first attempt at vocal synthesis (on "Riversong," and no, I don't think that's them singing through a Vocoder). This attracted the attention of a young musician named Steveland Wonder, and the results were Talking Book, Fullfillingness' First Finale and Innervisions.
TONTO did manage one live performance--either for The Midnight Special or Don Kirshner--in the mid-1970s, with Margouleff, Cecil and Billy Preston running the Mad Queen's Race. (If you can find the clip, you'll see what I mean.)
