I'd especially like this, but of course I trust your judgment.

This sounds really good. On a similar note, I have used a module in the past 
which was able to produce pulse division patterns from a pulse train (e.g., 
for 32 pulses divide by two, for the next 16 pulses divide by four, etc.) and 
was an extremely powerful sequencing tool; the kind of thing Rocket Man would 
enjoy I believe!

I've been holding my breath for that ladder filter!

BTW, thanks to Larry for the great tip on using the divider to tune over a 
wider range -- like all brilliant ideas, incredibly obvious, once I was told 
about it.
