This is is very powerful in the way it works, it features a full nine octaves over four voices of sound, linked as two stereo chanels. It also has a powerful Digital-to-Analogue converter and a frequency plus amplitude modulation support. This is what gives the CD32 the power to play almost any sound wave with out using the processor.
