•Triangle...
(Triangle wave data will be created.)
•Sine...

If you select a choice other than Disk Garbage, the actual sound data will
simply be created as an image in memory, meaning that the data will not be
saved as a sound file until you execute the [File] menu command [Save
As...].
If you have selected Square, Sawtooth, Triangle, or Sine, you can specify
the Amplitude and Frequency.
*Please be aware that playing back high volume full-scale data or data of
extremely low frequencies below 20 Hertz may damage your ears and/or any
speakers or headphones that are connected. Please use with caution.
*If your Macintosh has a 68K CPU, sawtooth wave, triangle wave, and sine
wave display will become extremely slow. In such cases, execute the [New]
command, and then save the newly created sound data to hard disk before
using it.
