1 An OSS/Free Driver for WaveFront soundcards
2 (Turtle Beach Maui, Tropez, Tropez Plus)
4 Paul Barton-Davis, July 1998
11 Requires: Kernel 2.1.106 or later (the driver is included with kernels
14 As of 7/22/1998, this driver is currently in *BETA* state. This means
15 that it compiles and runs, and that I use it on my system (Linux
16 2.1.106) with some reasonably demanding applications and uses. I
17 believe the code is approaching an initial "finished" state that
18 provides bug-free support for the Tropez Plus.
20 Please note that to date, the driver has ONLY been tested on a Tropez
21 Plus. I would very much like to hear (and help out) people with Tropez
22 and Maui cards, since I think the driver can support those cards as
25 Finally, the driver has not been tested (or even compiled) as a static
26 (non-modular) part of the kernel. Alan Cox's good work in modularizing
27 OSS/Free for Linux makes this rather unnecessary.

33 0) What does this driver do that the maui driver did not ?
34 **********************************************************************
36 * can fully initialize a WaveFront card from cold boot - no DOS
38 * working patch/sample/program loading and unloading (the maui
39 driver didn't document how to make this work, and assumed
40 user-level preparation of the patch data for writing
42 * full user-level access to all WaveFront commands
43 * for the Tropez Plus, (primitive) control of the YSS225 FX processor
44 * Virtual MIDI mode supported - 2 MIDI devices accessible via the
45 WaveFront's MPU401/UART emulation. One
46 accesses the WaveFront synth, the other accesses the
47 external MIDI connector. Full MIDI read/write semantics
49 * OSS-compliant /dev/sequencer interface for the WaveFront synth,
50 including native and GUS-format patch downloading.
51 * semi-intelligent patch management (prototypical at this point)
53 **********************************************************************
54 1) What to do about MIDI interfaces ?
55 **********************************************************************
57 The Tropez Plus (and perhaps other WF cards) can in theory support up
58 to 2 physical MIDI interfaces. One of these is connected to the
59 ICS2115 chip (the WaveFront synth itself) and is controlled by
60 MPU/UART-401 emulation code running as part of the WaveFront OS. The
61 other is controlled by the CS4232 chip present on the board. However,
62 physical access to the CS4232 connector is difficult, and it is
63 unlikely (though not impossible) that you will want to use it.
65 An older version of this driver introduced an additional kernel config
66 variable which controlled whether or not the CS4232 MIDI interface was
67 configured. Because of Alan Cox's work on modularizing the sound
68 drivers, and now backporting them to 2.0.34 kernels, there seems to be
69 little reason to support "static" configuration variables, and so this
70 has been abandoned in favor of *only* module parameters. Specifying
71 "mpuio" and "mpuirq" for the cs4232 parameter will result in the
72 CS4232 MIDI interface being configured; leaving them unspecified will
73 leave it unconfigured (and thus unusable).
75 BTW, I have heard from one Tropez+ user that the CS4232 interface is
76 more reliable than the ICS2115 one. I have had no problems with the
77 latter, and I don't have the right cable to test the former one
80 **********************************************************************
81 2) Why does line XXX of the code look like this .... ?
82 **********************************************************************
84 Either because it's not finished yet, or because you're a better coder
85 than I am, or because you don't understand some aspect of how the card
88 I absolutely welcome comments, criticisms and suggestions about the
89 design and implementation of the driver.

110 **********************************************************************
111 4) How do I compile/install/use it ?
112 **********************************************************************
114 PART ONE: install the source code into your sound driver directory
116 cd <top-of-your-2.1.106-code-base-e.g.-/usr/src/linux>
117 tar -zxvf <where-you-put/wavefront.tar.gz>
119 PART TWO: apply the patches
121 DO THIS ONLY IF YOU HAVE A KERNEL VERSION BELOW 2.1.109
122 AND HAVE NOT ALREADY INSTALLED THE PATCH(ES).
125 patch < wavefront.patch
127 PART THREE: configure your kernel
129 cd <top of your kernel tree>
130 make xconfig (or whichever config option you use)
132 - choose YES for Sound Support
133 - choose MODULE (M) for OSS Sound Modules
134 - choose MODULE(M) to YM3812/OPL3 support
135 - choose MODULE(M) for WaveFront support
136 - choose MODULE(M) for CS4232 support
138 - choose "N" for everything else (unless you have other
139 soundcards you want support for)
146 <whatever you normally do for a kernel install>

188 ************************************************************
189 6) How do I configure my card ?
190 ************************************************************
192 You need to edit /etc/modprobe.conf. Here's mine (edited to show the
196 alias char-major-14-* wavefront
197 alias synth0 wavefront
200 install wavefront /sbin/modprobe cs4232 && /sbin/modprobe -i wavefront && /sbin/modprobe opl3
201 options wavefront io=0x200 irq=9
202 options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
203 options opl3 io=0x388
207 the wavefront options "io" and "irq" ***MUST*** match the "synthio"
208 and "synthirq" cs4232 options.
210 you can do without the opl3 module if you don't
211 want to use the OPL/[34] FM synth on the soundcard
213 the opl3 io parameter is conventionally not adjustable.
214 In theory, any not-in-use IO port address would work, but
215 just use 0x388 and stick with the crowd.
217 **********************************************************************
218 7) What about firmware ?
219 **********************************************************************
221 Turtle Beach have not given me permission to distribute their firmware
222 for the ICS2115. However, if you have a WaveFront card, then you
223 almost certainly have the firmware, and if not, its freely available
224 on their website, at:
226 http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus
228 The file is called WFOS2001.MOT (for the Tropez+).
230 This driver, however, doesn't use the pure firmware as distributed,
231 but instead relies on a somewhat processed form of it. You can
232 generate this very easily. Following an idea from Andrew Veliath's
233 Pinnacle driver, the following flex program will generate the
236 ---- cut here -------------------------
239 ^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext);
240 <<EOF>> { fputc ('\0', stdout); return; }
243 ---- cut here -------------------------
245 To use it, put the above in file (say, ws.l) compile it like this:
247 shell> flex -ows.c ws.l
250 and then use it like this:
252 ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os
254 If you put it somewhere else, you'll always have to use the wf_ospath
255 module parameter (see below) or alter the source code.
257 **********************************************************************
258 7) How do I get it working ?
259 **********************************************************************
261 Optionally, you can reboot with the "new" kernel (even though the only
262 changes have really been made to a module).
268 You should get something like this in /var/log/messages:
270 WaveFront: firmware 1.20 already loaded.
274 WaveFront: no response to firmware probe, assume raw.
278 WaveFront: waiting for memory configuration ...
279 WaveFront: hardware version 1.64
280 WaveFront: available DRAM 8191k
281 WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty
282 WaveFront: 128 programs slots in use
283 WaveFront: 256 patch slots filled, 142 in use
285 The whole process takes about 16 seconds, the longest waits being
286 after reporting the hardware version (during the firmware download),
287 and after reporting program status (during patch status inquiry). Its
288 shorter (about 10 secs) if the firmware is already loaded (i.e. only
289 warm reboots since the last firmware load).
291 The "available DRAM" line will vary depending on how much added RAM
292 your card has. Mine has 8MB.
294 To check basically functionality, use play(1) or splay(1) to send a
295 .WAV or other audio file through the audio portion. Then use playmidi
296 to play a General MIDI file. Try the "-D 0" to hear the
297 difference between sending MIDI to the WaveFront and using the OPL/3,
298 which is the default (I think ...). If you have an external synth(s)
299 hooked to the soundcard, you can use "-e" to route to the
300 external synth(s) (in theory, -D 1 should work as well, but I think
301 there is a bug in playmidi which prevents this from doing what it
304 **********************************************************************
305 8) What are the module parameters ?
306 **********************************************************************
308 Its best to read wavefront.c for this, but here is a summary:
311 wf_raw - if set, ignore apparent presence of firmware
312 loaded onto the ICS2115, reset the whole
313 board, and initialize it from scratch. (default = 0)
315 fx_raw - if set, always initialize the YSS225 processor
316 on the Tropez plus. (default = 1)
318 < The next 4 are basically for kernel hackers to allow
319 tweaking the driver for testing purposes. >
321 wait_usecs - loop timer used when waiting for
322 status conditions on the board.
325 debug_default - debugging flags. See sound/wavefront.h
326 for WF_DEBUG_* values. Default is zero.
327 Setting this allows you to debug the
328 driver during module installation.
330 ospath - path to get to the pre-processed OS firmware.
331 (default: /etc/sound/wavefront.os)
