Subject: sound synth chip

After scouring the web, I am amazed at the lack of availability on
some basic sound generating chips. I've come across and played with
higher end Yamaha chips, the commodore SID chip, etc. etc. etc.
But I need something much simpler...
I basically need a chip that can produce 1 or more instrument timbres.
I can feed it frequencies or note values and it outputs music scale
tones. It can be monophonic, in other words reproduce a single tone at
the same time. It doesn't have to sound "professional" such as some of
the higher end wavetable chips on today's sound cards. I would prefer
to NOT build an analog synth such as Paia Fatman etc, although I've
considered that. Note that I do not want a MIDI enabled solution.
My question is: what do the cheapo kepboards you can buy at radio
shack and toystores use as their sound generating hardware? They all
seem to have a decent piano sound.
Followup questions: Do they do FM synthesis? So they produce sawtooth
waves and do subtractive synthesis on the wave form to produce
different sounds? Is my best bet just to take my 555 or other
oscillators and add differnet filters on the output? I really would
prefer to have an IC I can work with here.
Any and all help is appreciated.
