The driver is provided for Linux 1.2.x -and 2.[012].x kernels, as well as FreeBSD, on Intel x86 and DEC -Alpha systems. - -This driver was written by Takashi Iwai <iwai@ww.uni-erlangen.de>, -and provided "as is". The original source (awedrv-0.4.3.tar.gz) and -binary packages are available on the following URL: - http://bahamut.mm.t.u-tokyo.ac.jp/~iwai/awedrv/ -Note that since the author is apart from this web site, the update is -not frequent now. - - -* NOTE TO LINUX USERS - -To enable this driver on linux-2.[01].x kernels, you need turn on -"AWE32 synth" options in sound menu when configure your linux kernel -and modules. The precise installation procedure is described in the -AWE64-Mini-HOWTO and linux-kernel/Documetation/sound/AWE32. - -If you're using PnP cards, the card must be initialized before loading -the sound driver. There're several options to do this: - - Initialize the card via ISA PnP tools, and load the sound module. - - Initialize the card on DOS, and load linux by loadlin.exe - - Use PnP kernel driver (for Linux-2.x.x) -The detailed instruction for the solution using isapnp tools is found -in many documents like above. A brief instruction is also included in -the installation document of this package. -For PnP driver project, please refer to the following URL: - http://www-jcr.lmh.ox.ac.uk/~pnp/ - - -* USING THE DRIVER - -The awedrv has several different playing modes to realize easy channel -allocation for MIDI songs. To hear the exact sound quality, you need -to obtain the extended sequencer program, drvmidi or playmidi-2.5. - -For playing MIDI files, you *MUST* load the soundfont file on the -driver previously by sfxload utility. Otherwise you'll here no sounds -at all! All the utilities and driver source packages are found in the -above URL. The sfxload program is included in the package -awesfx-0.4.3.tgz. Binary packages are available there, too. See the -instruction in each package for installation. - -Loading a soundfont file is very simple. Just execute the command - - % sfxload synthgm.sbk - -Then, sfxload transfers the file "synthgm.sbk" to the driver. -Both SF1 and SF2 formats are accepted. - -Now you can hear midi musics by a midi player. - - % drvmidi foo.mid - -If you run MIDI player after MOD player, you need to load soundfont -files again, since MOD player programs clear the previous loaded -samples by their own data. - -If you have only 512kb on the sound card, I recommend to use dynamic -sample loading via -L option of drvmidi. 2MB GM/GS soundfont file is -available in most midi files. - - % sfxload synthgm - % drvmidi -L 2mbgmgs foo.mid - -This makes a big difference (believe me)! For more details, please -refer to the FAQ list which is available on the URL above. - -The current chorus, reverb and equalizer status can be changed by -aweset utility program (included in awesfx package). Note that -some awedrv-native programs (like drvmidi and xmp) will change the -current settings by themselves. The aweset program is effective -only for other programs like playmidi. - -Enjoy. - - -* COMPILE FLAGS - -Compile conditions are defined in awe_config.h. - -[Compatibility Conditions] -The following flags are defined automatically when using installation -shell script. - -- AWE_MODULE_SUPPORT - indicates your Linux kernel supports module for each sound card - (in recent 2.1 or 2.2 kernels and unofficial patched 2.0 kernels - as distributed in the RH5.0 package). - This flag is automatically set when you're using 2.1.x kernels. - You can pass the base address and memory size via the following - module options, - io = base I/O port address (eg. 0x620) - memsize = DRAM size in kilobytes (eg. 512) - As default, AWE driver probes these values automatically. - - -[Hardware Conditions] -You DON'T have to define the following two values. -Define them only when the driver couldn't detect the card properly. - -- AWE_DEFAULT_BASE_ADDR (default: not defined) - specifies the base port address of your AWE32 card. - 0 means to autodetect the address. - -- AWE_DEFAULT_MEM_SIZE (default: not defined) - specifies the memory size of your AWE32 card in kilobytes. - -1 means to autodetect its size. - - -[Sample Table Size] -From ver.0.4.0, sample tables are allocated dynamically (except -Linux-1.2.x system), so you need NOT to touch these parameters. -Linux-1.2.x users may need to increase these values to appropriate size -if the sound card is equipped with more DRAM. - -- AWE_MAX_SF_LISTS, AWE_MAX_SAMPLES, AWE_MAX_INFOS - - -[Other Conditions] - -- AWE_ALWAYS_INIT_FM (default: not defined) - indicates the AWE driver always initialize FM passthrough even - without DRAM on board. Emu8000 chip has a restriction for playing - samples on DRAM that at least two channels must be occupied as - passthrough channels. - -- AWE_DEBUG_ON (default: defined) - turns on debugging messages if defined. - -- AWE_HAS_GUS_COMPATIBILITY (default: defined) - Enables GUS compatibility mode if defined, reading GUS patches and - GUS control commands. Define this option to use GMOD or other - GUS module players. - -- CONFIG_AWE32_MIDIEMU (default: defined) - Adds a MIDI emulation device by Emu8000 wavetable. The emulation - device can be accessed as an external MIDI, and sends the MIDI - control codes directly. XG and GS sysex/NRPN are accepted. - No MIDI input is supported. - -- CONFIG_AWE32_MIXER (default: not defined) - Adds a mixer device for AWE32 bass/treble equalizer control. - You can access this device using /dev/mixer?? (usually mixer01). - -- AWE_USE_NEW_VOLUME_CALC (default: defined) - Use the new method to calculate the volume change as compatible - with DOS/Win drivers. This option can be toggled via aweset - program, or drvmidi player. - -- AWE_CHECK_VTARGET (default: defined) - Check the current volume target value when searching for an - empty channel to allocate a new voice. This is experimentally - implemented in this version. (probably, this option doesn't - affect the sound quality severely...) - -- AWE_ALLOW_SAMPLE_SHARING (default: defined) - Allow sample sharing for differently loaded patches. - This function is available only together with awesfx-0.4.3p3. - Note that this is still an experimental option. - -- DEF_FM_CHORUS_DEPTH (default: 0x10) - The default strength to be sent to the chorus effect engine. - From 0 to 0xff. Larger numbers may often cause weird sounds. - -- DEF_FM_REVERB_DEPTH (default: 0x10) - The default strength to be sent to the reverb effect engine. - From 0 to 0xff. Larger numbers may often cause weird sounds. - - -* ACKNOWLEDGMENTS - -Thanks to Witold Jachimczyk (witek@xfactor.wpi.edu) for much advice -on programming of AWE32. Much code is brought from his AWE32-native -MOD player, ALMP. -The port of awedrv to FreeBSD is done by Randall Hopper -(rhh@ct.picker.com). -The new volume calculation routine was derived from Mark Weaver's -ADIP compatible routines. -I also thank linux-awe-ml members for their efforts -to reboot their system many times :-) - - -* TODO'S - -- Complete DOS/Win compatibility -- DSP-like output - - -* COPYRIGHT - -Copyright (C) 1996-1998 Takashi Iwai - -This program is free software; you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation; either version 2 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
