[sdiy] OTA questions

[leaf at babble.vibrant.org]

Hi... I've been trying to find information on OTA's and havent been having
much luck.  Ideally, i'd like more of my gear to respond CV in.

Would some DIY'ers mind sharing some experience with OTA's?  I'm wondering
what considerations are there when using them, how important the offset
voltage is, what OTA's are recommended, and even any example circuits that
are online.  Basically - how does one go about placing an OTA inline with
a pot to have CV control?

thanks in advance!
