| 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. |
