- An OSS/Free Driver for WaveFront soundcards
- (Turtle Beach Maui, Tropez, Tropez Plus)
- Paul Barton-Davis, July 1998
- VERSION 0.2.5
- Driver Status
- -------------
- Requires: Kernel 2.1.106 or later (the driver is included with kernels
- 2.1.109 and above)
-
- As of 7/22/1998, this driver is currently in *BETA* state. This means
- that it compiles and runs, and that I use it on my system (Linux
- 2.1.106) with some reasonably demanding applications and uses. I
- believe the code is approaching an initial "finished" state that
- provides bug-free support for the Tropez Plus.
- Please note that to date, the driver has ONLY been tested on a Tropez
- Plus. I would very much like to hear (and help out) people with Tropez
- and Maui cards, since I think the driver can support those cards as
- well.
- Finally, the driver has not been tested (or even compiled) as a static
- (non-modular) part of the kernel. Alan Cox's good work in modularizing
- OSS/Free for Linux makes this rather unnecessary.
- Some Questions
- --------------
- **********************************************************************
- 0) What does this driver do that the maui driver did not ?
- **********************************************************************
- * can fully initialize a WaveFront card from cold boot - no DOS
- utilities needed
- * working patch/sample/program loading and unloading (the maui
- driver didn't document how to make this work, and assumed
- user-level preparation of the patch data for writing
- to the board. ick.)
- * full user-level access to all WaveFront commands
- * for the Tropez Plus, (primitive) control of the YSS225 FX processor
- * Virtual MIDI mode supported - 2 MIDI devices accessible via the
- WaveFront's MPU401/UART emulation. One
- accesses the WaveFront synth, the other accesses the
- external MIDI connector. Full MIDI read/write semantics
- for both devices.
- * OSS-compliant /dev/sequencer interface for the WaveFront synth,
- including native and GUS-format patch downloading.
- * semi-intelligent patch management (prototypical at this point)
- **********************************************************************
- 1) What to do about MIDI interfaces ?
- **********************************************************************
- The Tropez Plus (and perhaps other WF cards) can in theory support up
- to 2 physical MIDI interfaces. One of these is connected to the
- ICS2115 chip (the WaveFront synth itself) and is controlled by
- MPU/UART-401 emulation code running as part of the WaveFront OS. The
- other is controlled by the CS4232 chip present on the board. However,
- physical access to the CS4232 connector is difficult, and it is
- unlikely (though not impossible) that you will want to use it.
- An older version of this driver introduced an additional kernel config
- variable which controlled whether or not the CS4232 MIDI interface was
- configured. Because of Alan Cox's work on modularizing the sound
- drivers, and now backporting them to 2.0.34 kernels, there seems to be
- little reason to support "static" configuration variables, and so this
- has been abandoned in favor of *only* module parameters. Specifying
- "mpuio" and "mpuirq" for the cs4232 parameter will result in the
- CS4232 MIDI interface being configured; leaving them unspecified will
- leave it unconfigured (and thus unusable).
- BTW, I have heard from one Tropez+ user that the CS4232 interface is
- more reliable than the ICS2115 one. I have had no problems with the
- latter, and I don't have the right cable to test the former one
- out. Reports welcome.
- **********************************************************************
- 2) Why does line XXX of the code look like this .... ?
- **********************************************************************
- Either because its not finished yet, or because you're a better coder
- than I am, or because you don't understand some aspect of how the card
- or the code works.
- I absolutely welcome comments, criticisms and suggestions about the
- design and implementation of the driver.
- **********************************************************************
- 3) What files are included ?
- **********************************************************************
- drivers/sound/README.wavefront -- this file
- drivers/sound/wavefront.patch -- patches for the 2.1.106 sound drivers

- ************************************************************
- 6) How do I configure my card ?
- ************************************************************
- You need to edit /etc/modules.conf. Here's mine (edited to show the
- relevant details):
- # Sound system
- alias char-major-14 wavefront
- alias synth0 wavefront
- alias mixer0 cs4232
- alias audio0 cs4232
- pre-install wavefront modprobe "-k" "cs4232"
- post-install wavefront modprobe "-k" "opl3"
- options wavefront io=0x200 irq=9
- options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
- options opl3 io=0x388
- Things to note:
- the wavefront options "io" and "irq" ***MUST*** match the "synthio"
- and "synthirq" cs4232 options.
- you can do without the opl3 module if you don't
- want to use the OPL/[34] FM synth on the soundcard
- the opl3 io parameter is conventionally not adjustable.
- In theory, any not-in-use IO port address would work, but
- just use 0x388 and stick with the crowd.
- **********************************************************************
- 7) What about firmware ?
- **********************************************************************
- Turtle Beach have not given me permission to distribute their firmware
- for the ICS2115. However, if you have a WaveFront card, then you
- almost certainly have the firmware, and if not, its freely available
- on their website, at:
- http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus
- The file is called WFOS2001.MOT (for the Tropez+).
- This driver, however, doesn't use the pure firmware as distributed,
- but instead relies on a somewhat processed form of it. You can
- generate this very easily. Following an idea from Andrew Veliath's
- Pinnacle driver, the following flex program will generate the
- processed version:
- ---- cut here -------------------------
- %option main
- %%
- ^S[28].*r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext);
- <<EOF>> { fputc (' ', stdout); return; }
- n {}
- . {}
- ---- cut here -------------------------
- To use it, put the above in file (say, ws.l) compile it like this:
- shell> flex -ows.c ws.l
- shell> cc -o ws ws.c
-
- and then use it like this:
- ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os
- If you put it somewhere else, you'll always have to use the wf_ospath
- module parameter (see below) or alter the source code.
- **********************************************************************
- 7) How do I get it working ?
- **********************************************************************
- Optionally, you can reboot with the "new" kernel (even though the only
- changes have really been made to a module).
- Then, as root do:
- modprobe wavefront
- You should get something like this in /var/log/messages:
- WaveFront: firmware 1.20 already loaded.
- or
- WaveFront: no response to firmware probe, assume raw.
- then:
- WaveFront: waiting for memory configuration ...
- WaveFront: hardware version 1.64
- WaveFront: available DRAM 8191k
- WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty
- WaveFront: 128 programs slots in use
- WaveFront: 256 patch slots filled, 142 in use
- The whole process takes about 16 seconds, the longest waits being
- after reporting the hardware version (during the firmware download),
- and after reporting program status (during patch status inquiry). Its
- shorter (about 10 secs) if the firmware is already loaded (i.e. only
- warm reboots since the last firmware load).
- The "available DRAM" line will vary depending on how much added RAM
- your card has. Mine has 8MB.
- To check basically functionality, use play(1) or splay(1) to send a
- .WAV or other audio file through the audio portion. Then use playmidi
- to play a General MIDI file. Try the "-D 0" to hear the
- difference between sending MIDI to the WaveFront and using the OPL/3,
- which is the default (I think ...). If you have an external synth(s)
- hooked to the soundcard, you can use "-e" to route to the
- external synth(s) (in theory, -D 1 should work as well, but I think
- there is a bug in playmidi which prevents this from doing what it
- should).
- **********************************************************************
- 8) What are the module parameters ?
- **********************************************************************
- Its best to read wavefront.c for this, but here is a summary:
- integers:
- wf_raw - if set, ignore apparent presence of firmware
- loaded onto the ICS2115, reset the whole
- board, and initialize it from scratch. (default = 0)
- fx_raw - if set, always initialize the YSS225 processor
- on the Tropez plus. (default = 1)
- < The next 4 are basically for kernel hackers to allow
- tweaking the driver for testing purposes. >
- wait_usecs - loop timer used when waiting for
- status conditions on the board.
- The default is 150.
- debug_default - debugging flags. See sound/wavefront.h
- for WF_DEBUG_* values. Default is zero.
- Setting this allows you to debug the
- driver during module installation.
- strings:
- ospath - path to get to the pre-processed OS firmware.
- (default: /etc/sound/wavefront.os)
