   a sustained data transfer rate of 150 KB/s at no more than 40%
   of CPU bandwidth and reading at least 16 KB blocks.  The
   maximum average seek time is 1 second and the Mean Time
   Between Failure 10000 hours.  Capability Mode 1.

   bandwidth, preferably 44.1 kHz at no more than 15% of CPU
   bandwidth.  The synthesizer must support multi-voice,
   multi-timbral generation of six simultaneous melody notes and
