Last month, we examined the frankly scary maths allowing you to predict the audible effects of Frequency Modulation. This time, although the maths gets even tougher, Gordon Reid relates the theory to the practical implementation of FM synthesis on Yamaha's digital synths, as well as modular and non-modular analogues.

Christina Aguilera's debut single was a worldwide smash hit last year, thanks in no small measure to the distinctive work of producer and co‑writer David Frank. Mike Senior finds out how he did it.
As explained last month, audio-frequency modulation of the amplitude of a signal can be a powerful synthesis tool. The possibilities expand still further when we consider what happens when you use one audio-frequency signal to modulate the frequency of another...
Gordon Reid reveals some of the limitations of the 'classic' ADSR envelope with reference to a practical synthesis example, and explains some of the different types of envelopes found on 'classic' analogue synths, from AR envelopes right up to highly flexible digitally controlled EGs.
In Part 1 we explained how the tones of most real instruments can be reduced to patterns of harmonics, which can be generated using sine, saw, square or pulse waveforms. This month, we consider the sonic raw materials needed to imitate unpitched percussion.
How to find this classic multi-part 'synthesis explained' tutorial series on the current Sound On Sound site.
It was the best-selling single of last year, and signalled a radical change of musical direction for Cher — complete with bizarre vocal processing. Yet, surprisingly, it was produced in a small studio in West London. Sue Sillitoe relates the astonishing tale of 'Believe'.
