hi x0xers
is it possible to add an LFO to the x0x with one sine lets say..mm.. Sine or triangle..? and to make it with an LFO rate?
thanks, Isak.

Re: LFO
This would be fairly easy to do, there are heaps of LFO circuits out there, they are usually triangle/square wave occillators, e.g., check out the 'function generator on page 9, in the National App notes here:
http://www.national.com/an/AN/AN-31.pdf
You can make an LFO with just a Quad Op-Amp (LM324 / LF347 etc.), 2 amps for the Triangle /Square wave generators and 2 more for the voltage follower / output buffers.
here is a working triangle LFO: http://www.massmind.org/images/www/hobb ... _ckt16.htm
The bigger the capacitor (C1) is the lower the frequency will be.
For anyone else interested, the AN-31 is a 'classic' application note from National which shows a lot of useful types of 'fundamental' Op-Amp designs.
Also it may be easier to make an LFO with a LM555 Timer, as you can easily just use the one power rail in the x0x.
Look on Google etc. for '555 oscillator'.
