I'm not sure! One is probably enough!

That's the first time I've heard that one before! Nice. I'm keeping
that. Anyone got anything to say about the actual synthesis technique
;)

Not at all. I'm quite enjoying this. Pieman is winning so far in
having made me fall around the place with his last comment. I just had
a look at the Computer Music Tutorial and it has a few sections on
Walsh synthesis in there. I think I came across it in a Miranda text
book too. I'm surprised I've not read more about it.

As far as I concerned, the Walsh synthesis is a synthesis based on Walsh
basis, i.e. the combinations of orthogonal rectangle waves. It can be
reviewed as a Haar wavelet packet transform I guess. 
Therefore, in that case you may start from GEN Wave (including some examples
around it). It allows you to use any compactly supported basis for signal
analysis and/or synthesis.
