18 | * Private events for Gravis Ultrasound (GUS) | ||
19 | * | ||
20 | * Format: | ||
21 | * byte 0 - SEQ_PRIVATE (0xfe) | ||
22 | * byte 1 - Synthesizer device number (0-N) | ||
23 | * byte 2 - Command (see below) | ||
24 | * byte 3 - Voice number (0-31) | ||
25 | * bytes 4 and 5 - parameter P1 (unsigned short) | ||
26 | * bytes 6 and 7 - parameter P2 (unsigned short) | ||
27 | * | ||
28 | * Commands: | ||
29 | * Each command affects one voice defined in byte 3. | ||
30 | * Unused parameters (P1 and/or P2 *MUST* be initialized to zero). | ||
31 | * _GUS_NUMVOICES - Sets max. number of concurrent voices (P1=14-31, default 16) | ||
32 | * _GUS_VOICESAMPLE- ************ OBSOLETE ************* | ||
33 | * _GUS_VOICEON - Starts voice (P1=voice mode) | ||
34 | * _GUS_VOICEOFF - Stops voice (no parameters) | ||
35 | * _GUS_VOICEFADE - Stops the voice smoothly. | ||
36 | * _GUS_VOICEMODE - Alters the voice mode, don't start or stop voice (P1=voice mode) | ||
37 | * _GUS_VOICEBALA - Sets voice balence (P1, 0=left, 7=middle and 15=right, default 7) | ||
38 | * _GUS_VOICEFREQ - Sets voice (sample) playback frequency (P1=Hz) | ||
39 | * _GUS_VOICEVOL - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off) | ||
40 | * _GUS_VOICEVOL2 - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off) | ||
41 | * (Like GUS_VOICEVOL but doesn't change the hw | ||
42 | * volume. It just updates volume in the voice table). | ||
43 | * | ||
44 | * _GUS_RAMPRANGE - Sets limits for volume ramping (P1=low volume, P2=high volume) | ||
45 | * _GUS_RAMPRATE - Sets the speed for volume ramping (P1=scale, P2=rate) | ||
46 | * _GUS_RAMPMODE - Sets the volume ramping mode (P1=ramping mode) | ||
47 | * _GUS_RAMPON - Starts volume ramping (no parameters) | ||
48 | * _GUS_RAMPOFF - Stops volume ramping (no parameters) | ||
49 | * _GUS_VOLUME_SCALE - Changes the volume calculation constants | ||
50 | * for all voices. | ||
