Keywords: sound 520st wave ST-BASIC envelope

Having just received my copy of ST Basic, I've been writing some short
programs to play with the built in sound chip.  The manual page for the
"wave" command is missing the table of various envelopes available for the
sound chip.  Does anyone have such a table handy?

I HAVE figured out a few combinations.  For example this gives you a nice
"ocean wave" effect:

wave &h8,&h1,14,30000,1

Is it possible to set up two or three *seperate* envelopes?  One for each
voice perhaps?  Is I read the manual I don't think you can do it from basic,
but perhaps you could "poke" the settings into the chip?
