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.
