Cortex: delete ToneProducer add-on.
The version of this in src/add-ons/media/media-add-ons/tone_producer_demo/ is virtually identical, plus it is under a more permissive license (Be Sample Code vs. BSD 3-Clause) and already fixed for 64bit.

NOTES [email protected] 11june99
|
||||
- this node has some holes in it, but it's pretty useful starting
|
||||
point for writing producers.
|
||||
- I've tried to clean up the format negotiation a bit, which didn't
|
||||
fare too well when faced with an apathetic downstream node
|
||||
(LoggingConsumer.)
|
||||
|
||||
KNOWN BUGS

How embarrassing.
