+OVERVIEW
+
+ EWF stands for "Echo Waveform Format" and it's the format in which PCM
+ instruments are stored.
+
+FORMAT
+
+ There isn't much to it. PCM data is stored as unsigned 8-bit, 10250 Hz,
+ mono. The bytes specifying the waveform data contain values ranging from
+ $00 to $FE. When a byte with value $FF is found, this is the end of the
+ waveform.
