I *think*, but I'm not that sure and cannot test currently, that all
message passing is limited to the 64 samples minimum. To get faster,
you will need to resort to signal connections or the time tagged
triggers from iemlib.

I don't have a Windows C compiler, too. I don't even have Windows. :)
Now, I think, that only Visual C++ from MS is able to compile Pd on
Windows. This might not be valid for externals, though.

No umbrella, sorry: $x only works if it's at the begining of the
identifier. So $x-name is okay, name-$x is not.

Here's an alternative:

[inlet] 
 |
[symbol]
 |
[select sawtooth square ...]
 |       |       ...     |   
 |
[set $1(                [ print Unknown_Waveform]
 |
 |
[whatever wants to read the array]

Another thing to think about here, is if it is possible to put all
common behaviour into an abstraction. If most of the sound generation
seems to be the same, except the different table contents, you might
want to put the table content into a file ( tablename write/read
somename.txt) and use an abstraction argument to select the waveform
file. 

Just a suggestion. 

ciao
