|
|
|
* 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)
|
2009-04-15 06:14:17 +04:00
|
|
|
* _GUS_VOICEBALA - Sets voice balance (P1, 0=left, 7=middle and 15=right, default 7)
|
2005-04-17 02:20:36 +04:00
|
|
|
* _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.
