OK you can do some kind of script....
The synthetic sound editor
An simple but much less memory-consuming alternative to the sample is the
synthetic sound (or "synthsound"). Synthsounds are artifically generated by
OctaMED, and are designed using the synthetic sound editor (Display menu).
Synthsounds are made up of one or more simple "waveforms". You can select
one of the predefined waveforms from the Preset menu, or draw your own by
dragging the mouse along a "waveform display" (one of the two speckled
boxes).
The waveforms are then linked together (although many synthsounds consist of
just a single waveform), and their volume and pitch altered by creating a
"synthsound script", a sequence of simple commands and values. A list of
available commands can be found in the help guide.

and follow the links to synthetic sounds.
