Put together from a number of schematics I'd been looking at to see how to do this. Got kinda confusing; think I'll stick to one scheme from know on. The op amps take up a lot of space, so I couldn't get it laid out very well on here, pretty confusing to look at. Wanted to add sawtooth, but ran out of space. Seems take a while for the sine to settle down and it looses amplitude at each stage. Any advise appreciated.
