Multi-Channel
Effects
Because of the independent architecture of the PSG, many rather
complex effects are possible without burdening the processor. For
example, the Wolf Whistle effect in Fig. 32 shows two channels in use
to add constant breath hissing noise to the three concentrated
frequency sweeps of the whistle. Once the noise is put on the
channel, the processor only need be concerned with the frequency
sweep operation.
