Driver Status
|
9 |
|
|
-------------
|
10 |
|
|
|
11 |
|
|
Requires: Kernel 2.1.106 or later (the driver is included with kernels
|
12 |
|
|
2.1.109 and above)
|
13 |
|
|
|
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.
|
19 |
|
|
|
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
|
23 |
|
|
well.
|
24 |
|
|
|
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.

0) What does this driver do that the maui driver did not ?
|
34 |
|
|
**********************************************************************
|
35 |
|
|
|
36 |
|
|
* can fully initialize a WaveFront card from cold boot - no DOS
|
37 |
|
|
utilities needed
|
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
|
41 |
|
|
to the board. ick.)
|
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
|
48 |
|
|
for both devices.
|
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)

**********************************************************************

54 |
|
|
1) What to do about MIDI interfaces ?
|
55 |
|
|
**********************************************************************
|
56 |
|
|
|
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.
|
64 |
|
|
|
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).
|
74 |
|
|
|
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
|
78 |
|
|
out. Reports welcome.

2) Why does line XXX of the code look like this .... ?
|
82 |
|
|
**********************************************************************
|
83 |
|
|
|
84 |
|
|
Either because its 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
|
86 |
|
|
or the code works.
|
87 |
|
|
|
88 |
|
|
I absolutely welcome comments, criticisms and suggestions about the
|
89 |
|
|
design and implementation of the driver.

4) How do I compile/install/use it ?
|
112 |
|
|
**********************************************************************
|
113 |
|
|
|
114 |
|
|
PART ONE: install the source code into your sound driver directory
|
115 |
|
|
|
116 |
|
|
cd
|
117 |
|
|
tar -zxvf
|
118 |
|
|
|
119 |
|
|
PART TWO: apply the patches
|
120 |
|
|
|
121 |
|
|
DO THIS ONLY IF YOU HAVE A KERNEL VERSION BELOW 2.1.109
|
122 |
|
|
AND HAVE NOT ALREADY INSTALLED THE PATCH(ES).
|
123 |
|
|
|
124 |
|
|
cd drivers/sound
|
125 |
|
|
patch < wavefront.patch
|
126 |
|
|
|
127 |
|
|
PART THREE: configure your kernel
|
128 |
|
|
|
129 |
|
|
cd
|
130 |
|
|
make xconfig (or whichever config option you use)
|
131 |
|
|
|
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
|
137 |
|
|
|
138 |
|
|
- choose "N" for everything else (unless you have other
|
139 |
|
|
soundcards you want support for)
|
140 |
|
|
|
141 |
|
|
|
142 |
|
|

6) How do I configure my card ?

You need to edit /etc/modules.conf. Here's mine (edited to show the
|
194 |
|
|
relevant details):
|
195 |
|
|
|
196 |
|
|

200 |
|
|
alias audio0 cs4232
|
201 |
|
|
pre-install wavefront modprobe "-k" "cs4232"
|
202 |
|
|
post-install wavefront modprobe "-k" "opl3"
|
203 |
|
|
options wavefront io=0x200 irq=9
|
204 |
|
|
options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
|
205 |
|
|
options opl3 io=0x388
|
206 |
|
|
|
207 |
|
|
Things to note:
|
208 |
|
|
|
209 |
|
|
the wavefront options "io" and "irq" ***MUST*** match the "synthio"
|
210 |
|
|
and "synthirq" cs4232 options.
|
211 |
|
|
|
212 |
|
|
you can do without the opl3 module if you don't
|
213 |
|
|
want to use the OPL/[34] FM synth on the soundcard
|
214 |
|
|
|
215 |
|
|
the opl3 io parameter is conventionally not adjustable.
|
216 |
|
|
In theory, any not-in-use IO port address would work, but
|
217 |
|
|
just use 0x388 and stick with the crowd.

7) What about firmware ?
|
221 |
|
|
**********************************************************************
|
222 |
|
|
|
223 |
|
|
Turtle Beach have not given me permission to distribute their firmware
|
224 |
|
|
for the ICS2115. However, if you have a WaveFront card, then you
|
225 |
|
|
almost certainly have the firmware, and if not, its freely available
|
226 |
|
|
on their website, at:
|
227 |
|
|
|
228 |
|
|
http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus
|
229 |
|
|
|
230 |
|
|
The file is called WFOS2001.MOT (for the Tropez+).
|
231 |
|
|
|
232 |
|
|
This driver, however, doesn't use the pure firmware as distributed,
|
233 |
|
|
but instead relies on a somewhat processed form of it. You can
|
234 |
|
|
generate this very easily. Following an idea from Andrew Veliath's
|
235 |
|
|
Pinnacle driver, the following flex program will generate the
|
236 |
|
|
processed version:
|
237 |
|
|
|
238 |
|
|
---- cut here -------------------------
|
239 |
|
|
%option main
|
240 |
|
|
%%
|
241 |
|
|
^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext);
|
242 |
|
|
<> { fputc ('\0', stdout); return; }
|
243 |
|
|
\n {}
|
244 |
|
|
. {}
|
245 |
|
|
---- cut here -------------------------
|
246 |
|
|
|
247 |
|
|
To use it, put the above in file (say, ws.l) compile it like this:
|
248 |
|
|
|
249 |
|
|
shell> flex -ows.c ws.l
|
250 |
|
|
shell> cc -o ws ws.c
|
251 |
|
|
|
252 |
|
|
and then use it like this:
|
253 |
|
|
|
254 |
|
|
ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os
|
255 |
|
|
|
256 |
|
|
If you put it somewhere else, you'll always have to use the wf_ospath
|
257 |
|
|
module parameter (see below) or alter the source code.
|
258 |
|
|
|
259 |
|
|
**********************************************************************
|
260 |
|
|
7) How do I get it working ?
|
261 |
|
|
**********************************************************************
|
262 |
|
|
|
263 |
|
|
Optionally, you can reboot with the "new" kernel (even though the only
|
264 |
|
|
changes have really been made to a module).
|
265 |
|
|
|
266 |
|
|
Then, as root do:
|
267 |
|
|
|
268 |
|
|
modprobe wavefront
|
269 |
|
|
|
270 |
|
|
You should get something like this in /var/log/messages:
|
271 |
|
|
|
272 |
|
|
WaveFront: firmware 1.20 already loaded.
|
273 |
|
|
|
274 |
|
|
or
|
275 |
|
|
|
276 |
|
|
WaveFront: no response to firmware probe, assume raw.
|
277 |
|
|
|
278 |
|
|
then:
|
279 |
|
|
|
280 |
|
|
WaveFront: waiting for memory configuration ...
|
281 |
|
|
WaveFront: hardware version 1.64
|
282 |
|
|
WaveFront: available DRAM 8191k
|
283 |
|
|
WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty
|
284 |
|
|
WaveFront: 128 programs slots in use
|
285 |
|
|
WaveFront: 256 patch slots filled, 142 in use
|
286 |
|
|
|
287 |
|
|
The whole process takes about 16 seconds, the longest waits being
|
288 |
|
|
after reporting the hardware version (during the firmware download),
|
289 |
|
|
and after reporting program status (during patch status inquiry). Its
|
290 |
|
|
shorter (about 10 secs) if the firmware is already loaded (i.e. only
|
291 |
|
|
warm reboots since the last firmware load).
|
292 |
|
|
|
293 |
|
|
The "available DRAM" line will vary depending on how much added RAM
|
294 |
|
|
your card has. Mine has 8MB.
|
295 |
|
|
|
296 |
|
|
To check basically functionality, use play(1) or splay(1) to send a
|
297 |
|
|
.WAV or other audio file through the audio portion. Then use playmidi
|
298 |
|
|
to play a General MIDI file. Try the "-D 0" to hear the
|
299 |
|
|
difference between sending MIDI to the WaveFront and using the OPL/3,
|
300 |
|
|
which is the default (I think ...). If you have an external synth(s)
|
301 |
|
|
hooked to the soundcard, you can use "-e" to route to the
|
302 |
|
|
external synth(s) (in theory, -D 1 should work as well, but I think
|
303 |
|
|
there is a bug in playmidi which prevents this from doing what it
|
304 |
|
|
should).

Its best to read wavefront.c for this, but here is a summary:

311 |
|
|
|
312 |
|
|
integers:
|
313 |
|
|
wf_raw - if set, ignore apparent presence of firmware
|
314 |
|
|
loaded onto the ICS2115, reset the whole
|
315 |
|
|
board, and initialize it from scratch. (default = 0)
|
316 |
|
|
|
317 |
|
|
fx_raw - if set, always initialize the YSS225 processor
|
318 |
|
|
on the Tropez plus. (default = 1)
