Due to limited resources an LFO will have to be a separate design. It's 
come up often enough that I'd be interested in what folks would like to 
see in an LFO. A few questions:

* How stable does it have to be? (Is 2.5% enough?)
* Is 1V/Oct necessary, or is linear OK?
* I assume that hard sync would be useful. True?
* Frequency range?
* Output voltage range (+/- 5V, or 0-10V?)
* Waveforms?
* Other features?
