> SOUND [RANDOM 10000 100]

Yes RANDOM only takes a list of numbers. But you can build
that list on the fly with a function called LIST.
The problem is not you misunderstanding of SOUND but more
how lists work and are created in Logo.

SOUND (list random 10000 100)

See the second example in the online help of SETPENCOLOR.
It's a common confusion.

Or you might want to have bigger "jumps" between the freq's so
you can hear the differences better.

make "freq (random 20)*1000
SOUND (list :freq 100)

Now try mapping a MOUSE Y position to the freq and the X pos to
the duration. See MOUSEON (you'll have to SCALE and OFFSET)
the X and Y values so that they are within reason for SOUND.

MSWLogo's online help and examples.
Jim's The Great Logo Adventure.
Lot's of stuff on the Web and Logo-l mailing list
And Brians books (See his web page)

Are some of the best sources.

Links to all that information is on MSWLogo's web page.

Many of them are dyslexic, and strongly visual and kinesthetic learners. My primary goal is to teach them to think better, and improve their decision making capabilities, but one has to start somewhere.

I've also done a lot of real-time programming in FORTH and of course assembler, and spent many years in software quality management roles. I read your papers on education and agree with your philosophies. Right now I'm teaching in Merrimack, NH. I'm using both LOGO to teach principles and good software discipline, and will add some VBA (Visual Basic for Applications in a few weeks to also give them some commercially useful skills.
