Free virtual signal generator. My buddy sent me this and although I have not had much time with it he sez it's very lo distortion, as good as his Audio Precision. YMMV

If you're an adventurist, see the CA3140(a) data sheet:

Look at Fig. 10d

That datasheet includes all circuits for those modules, which make a complete "analog" Funct Gen. (no digital readout).
...But...if someone actually makes one...I'd like to see it. I may try one day...... (I mean week!).
