Variable 'i' simulates the time base...

Yeah I know. It's only a draft to show the idea. It is not real code and
shows only the main concept.

It is quite easy. To get a square wave just make a function like this:

function squareWave (i,freq)
   if sin(i*freq) > 0 then squareWave = 1
      else
         if sin(i*freq) = 0 then squareWave = 0
             else
             if sin(i*freq) <0 then squareWave = 1
end function

for a sawtooth wave you may use the MOD operator (the modulo or remainer of
a division of "i" by frequency, etc.

There exist lots of C-Sound resources on the net, thousands of examples,
instruments, scores, etc.
With C-Sound it is an easier task because it has built-in functions for
oscillators, filters, FM, etc.

Take a look at http://www.adp-gmbh.ch/csound/fm/index.html for some nice
examples of FM instruments generated with CSound.

Here is a good tutorial to get into Csound:
