While looking for some code to generate sound with mbed or arduino, I came
across this DDS technique.
Has anyone used this before and could it be of use for csound?

here's a link: http://en.wikipedia.org/wiki/Direct_digital_synthesizer

That appears to be a description of standard wavetable synthesis.

Csound does exactly this already. All "digital audio synthesizers" do
exactly this already. What is described in the article is just a
simple digital oscillator. The "clock" is just the sampling rate and
the time according to this clock is just the current sample frame.
Csound has many kinds of digital oscillator.

Of course! Since it uses a single waveform as a lookup table...
