[PD] $-Dollar sign variables instantiation

[Kevin McCoy]

Hi Brien,

I got some help on a similar problem a while ago - check this out:

http://lists.puredata.info/pipermail/pd-list/2006-06/039027.html

The basic idea is that in order to use $2 and on, you have to pack the
elements into a list.  Then when you send that list into an object, you can
start accessing more than just $1.  In the dollarsign example it's not very
clear, but it makes more sense here:
http://crca.ucsd.edu/~msp/Pd_documentation/x2.htm#s6.5<http://crca.ucsd.edu/%7Emsp/Pd_documentation/x2.htm#s6.5>

There are a couple of things I'm not mentioning - if you use "subpatches"
(abstractions) you can specify creation arguments.  That's what the
dollarsign example in the control examples is doing.  But it sounds like you
just need to pack into a list.

Good luck,
Kevin
