+
+/*
+ *	Private events for Gravis Ultrasound (GUS)
+ *
+ *	Format:
+ *		byte 0 		- SEQ_PRIVATE (0xfe)
+ *		byte 1 		- Synthesizer device number (0-N)
+ *		byte 2 		- Command (see below)
+ *		byte 3 		- Voice number (0-31)
+ *		bytes 4 and 5	- parameter P1 (unsigned short)
+ *		bytes 6 and 7	- parameter P2 (unsigned short)
+ *
+ *	Commands:
+ *		Each command affects one voice defined in byte 3.
+ *		Unused parameters (P1 and/or P2 *MUST* be initialized to zero).
+ *		_GUS_NUMVOICES	- Sets max. number of concurrent voices (P1=14-31, default 16)
+ *		_GUS_VOICESAMPLE- ************ OBSOLETE *************
+ *		_GUS_VOICEON	- Starts voice (P1=voice mode)
+ *		_GUS_VOICEOFF	- Stops voice (no parameters)
+ *		_GUS_VOICEFADE	- Stops the voice smoothly.
+ *		_GUS_VOICEMODE	- Alters the voice mode, don't start or stop voice (P1=voice mode)
+ *		_GUS_VOICEBALA	- Sets voice balance (P1, 0=left, 7=middle and 15=right, default 7)
+ *		_GUS_VOICEFREQ	- Sets voice (sample) playback frequency (P1=Hz)
+ *		_GUS_VOICEVOL	- Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
+ *		_GUS_VOICEVOL2	- Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
+ *				  (Like GUS_VOICEVOL but doesn't change the hw
+ *				  volume. It just updates volume in the voice table).
+ *
+ *		_GUS_RAMPRANGE	- Sets limits for volume ramping (P1=low volume, P2=high volume)
+ *		_GUS_RAMPRATE	- Sets the speed for volume ramping (P1=scale, P2=rate)
+ *		_GUS_RAMPMODE	- Sets the volume ramping mode (P1=ramping mode)
+ *		_GUS_RAMPON	- Starts volume ramping (no parameters)
+ *		_GUS_RAMPOFF	- Stops volume ramping (no parameters)
+ *		_GUS_VOLUME_SCALE - Changes the volume calculation constants
+ *				  for all voices.
