  40  *              byte 1          - Synthesizer device number (0-N)

  42  *              byte 3          - Voice number (0-31)
  43  *              bytes 4 and 5   - parameter P1 (unsigned short)
  44  *              bytes 6 and 7   - parameter P2 (unsigned short)
  45  *
  46  *      Commands:
  47  *              Each command affects one voice defined in byte 3.
  48  *              Unused parameters (P1 and/or P2 *MUST* be initialized to zero).
  49  *              _GUS_NUMVOICES  - Sets max. number of concurrent voices (P1=14-31, default 16)
  50  *              _GUS_VOICESAMPLE- ************ OBSOLETE *************
  51  *              _GUS_VOICEON    - Starts voice (P1=voice mode)
  52  *              _GUS_VOICEOFF   - Stops voice (no parameters)
  53  *              _GUS_VOICEFADE  - Stops the voice smoothly.
  54  *              _GUS_VOICEMODE  - Alters the voice mode, don't start or stop voice (P1=voice mode)
  55  *              _GUS_VOICEBALA  - Sets voice balence (P1, 0=left, 7=middle and 15=right, default 7)
  56  *              _GUS_VOICEFREQ  - Sets voice (sample) playback frequency (P1=Hz)
  57  *              _GUS_VOICEVOL   - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
  58  *              _GUS_VOICEVOL2  - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
  59  *                                (Like GUS_VOICEVOL but doesn't change the hw
  60  *                                volume. It just updates volume in the voice table).
  61  *
  62  *              _GUS_RAMPRANGE  - Sets limits for volume ramping (P1=low volume, P2=high volume)
  63  *              _GUS_RAMPRATE   - Sets the speed for volume ramping (P1=scale, P2=rate)
  64  *              _GUS_RAMPMODE   - Sets the volume ramping mode (P1=ramping mode)
  65  *              _GUS_RAMPON     - Starts volume ramping (no parameters)
  66  *              _GUS_RAMPOFF    - Stops volume ramping (no parameters)
  67  *              _GUS_VOLUME_SCALE - Changes the volume calculation constants
  68  *                                for all voices.
