I put the manual for my second Slipmat prototype online for convenient viewing.

I still believe Csound would greatly benefit from giving users the
option to create generic classes/templates that can be easily
imported, reused, remixed and graphed. Though the working prototype is
nothing more than a pre-processor, and a crude one at that, it does
show that there is a path to incorporate classes/templates in a
fashion that is still very Csound in nature, and does so without
breaking backwards compatibility.
