A sample of the S&S LFO in action can be heard at the bottom of the <a href="http://www.casperelectronics.com/finished-pieces/speak-n-spell/speakspell-bending/">Speak&Spell Bending</a> page. It's actually a Speak&Math in the sample. I start the S&M with the LFO on and then activate the "HOLD" mod which stays on through the whole sample.
