Yes that is right. The sounds isn't very fat (more poor) but the IC is nice
when you want to start with building your own synth because you only need a
few external parts to make a lot of sound.

My first synthesizer had the SN76477. There is a picture on my homepage if
anyone is interested (address in the footer). The synth itself doesn't exist
any longer. I recycled all the parts for other projects.

I think it would be very difficult to find any of these chips in a shop
because they are really old. I had a few spare chips but sold all of them
exept one. If anyone is specially interested in these chip I could sell it...

I have also an article of a German Electronic magazine showing some circuits
and also an universal circuit - you can do all the functions of the chip
with these circuit (yes and this circuit was the schematic for my synth... a
lot of switches and pots).

Ciao
