In this way, the device would “sing” some ethereal version of whatever music was fed to it, in tune. Maybe, with single opamp filters, this is doable.</span></div></div></o:smarttagtype></o:smarttagtype></o:smarttagtype></div></blockquote><div><br class=""></div>Different kind of thing, but this reminds me of a very nice audio plugin reverb I have from PSP-Audio. It’s called Pianoverb, an I believe there is a free version. It basically sounds like the soundboard of a piano with the dampers lifted off the strings. The strings then resonate with the music you play through it.</div><div><br class=""></div><div>Ben</div><div><br class=""></div></body></html>
