Multiple Tones with vibrato

[CLUELESS1]

I have a project on a childs toy guitar. It has 5 buttons on the fret part that did play noises. I am trying to find how to make something thats not just a horrible beep. Has to make more than 1 noise at a time, something with vibrato. I admit jumping to a 555 but that only produced clicks or a screechy tone like the old stylophones. Any ideas? Anybody done something similar (ie not the Old Farts diesel train)

Thanks

I did this a while back. Play the file, it does sound a bit like a guitar twang !.

Many thanks, that sounds perfect. 5 buttons need 5 08M2 or larger Picaxe. Will go back and read more on your thread. Thanks for quick response.
