1 terminatorX - ChangeLog
2 All changes were done by me (Alexander König) if not stated otherwise.
3 This is not a GNU-style ChangeLog but you sort of get the idea what was
7 - Enhanced audio data display - you can now zoom into the audio signal, which
8 should allow much more precise scratching with larger audio files (ie
9 complete tracks). On playback terminatorX will scroll the displayed area
10 to ensure you always see the area of the sample in which you currently
12 - fixed a gcc 3.2 compilation bug - thanks to
13 Adam Duck <duck@informatik.uni-frankfurt.de>
16 - Fixed a compilation bug ocurring on big endian systems only.
17 - Fixed the built-in wav loading routines for big endian systems (again).
18 - Finally traced down and fixed a long outstanding bug in the dial widget,
19 the background of the dials is now drawn correctly.
20 - Ported terminatorX to gtk+ Version 2. The code for gtk2 will be enabled
21 when gtk2 is detected by configure. To force terminatorX to use the good
22 old gtk 1.2.x (x>=5) run configure with the '--disable-gtk2' switch.
23 WARNING: gdkxft-users: gtk2 applications segfault when preloading
24 libgdk_xft.so! So unset LD_PRELOAD and set GDK_USE_XFT=1 instead.
25 - Applied a patch from Adrian that brings lots of new stuff:
26 - Debian package support (removed - Mike Furr now maintains an official
27 Debain package for terminatorX)
28 - enhanced GNOME integration
29 - a manpage for terminatorX
30 - Included another gcc3 fix thanks to Gregor Riepl <seto-kun@freesurf.ch>
31 - Improved configure's compatibilty - it should detect pthreads more reliably
32 and it should detect ladspa.h when located in /usr/local/include without
33 /usr/local/include being contained in the include path.
34 - This release should compile and run on FreeBSD systems and possibly
35 OpenBSD, too. Thanks for help and testing this goes to
36 Tilman Linneweh <tilman@arved.de>.
37 - Sequencer now refuses to play when no events available - and displays
38 a dialog that suggests running the audio engine.
39 - De-uglified the terminatorX note dialog.
40 - Fixed gtk+2 signals for load file dialog
41 - Pre-listen support for mpg321
42 - Added a new auto-hiding "panel-bar" to which turntable control and audio
43 panels can be minimized to.
44 - Cleaned up the turntables' audio panel for better looks and easier usage
45 - Rewrote the engine thread completely - unlike before the engine thread
46 is created on startup and kept alive until termination.
47 - terminatorX can now be run suid root - and it might even be safe. After
48 creating the engine thread both terminatorX threads drop root privileges
49 before evaluating any parameters or reading/writing files, etc. The problem
50 is the pthread "manager thread" is out of control of terminatorX code - so
51 I cannot tell that thread to drop privileges.
52 - Fixed Drag'n'Drop for GNOME 2
53 - To enhance the loading of audiofiles terminatorX now contains code to use
54 mad (MPEG Audio Decoder), libvorbis and libaudiofile directly instead of
55 pipeing audio data through mpg123, ogg123 or sox. As a result the new routines
56 bring following advantages:
57 - tX loads audiofiles significantly faster
58 - tX now honours the samplerate of an audiofile
59 (by adjusting the pitch of the turntable)
60 - tX provides much better feedback on the loading progress
61 Although the old loading-methods are still available (and piped loading has
62 been improved, too) I highly recommend installing the libraries above as the
63 new routines simply work better.
64 - Deleted tons of old outdated code in tX_engine.cc and tX_mastergui.cc
67 - Applied a patch from Matthew Evans <activesx@hotmail.com> that introduces
68 support for Ogg Vorbis audiofiles. It requires ogg123 > RC2 and sox to work.
69 Autodetection is supported via configure (--enable-ogg123).
70 - Experimental support for input devices other than the core-pointer
71 under XFree86 > 4. This uses the xsetpointer executable that comes with
72 XFree86. configure should autodetect this correctly, in case it doesn't
73 use the --enable-xetpointer switch.
74 - Adrian sent me a patch introducing two new buttons: mute and solo. As it
75 didn't fully harmonize with the sequencer I rewrote parts of it and added new
76 functionality to the turntables: They can now be switched to mix_solo or
77 mix_mute - these settings affect current mixing only - their values will
78 neither be saved nor will changes to those control be recorded in the
79 sequencer - if you want to record muting events either use the mute button
80 from the turntable's trigger menu, the keyboard short-cuts (alt/strg), or
81 your middle mouse button.
82 - fixed a bug that produced corrupt wavfiles on big endian machines
83 - some minor fixes to make terminatorX compile with newer gcc releases
84 - Well, I am allowed to change my mind, aren't I? Anyway, 3DNow! is back.
85 Nevertheless newer gcc releases seem to have a bug in handling movq and
86 the current 3DNow! stereo implementation does not seem to be very efficient.
87 So use --enable-3dnow only if you want to help me improve perfomance.
88 - Modified the mpg123 loader in order to make it work with mpg321, too.
89 mpg321 lacks support for mpg123's -m switch ("singlemix") therefor
90 mpg?2?'s output is now piped into sox to convert the signal to mono.
91 For this reason mpg?2? support now requires sox to be installed, too.
92 - added a workaround for a gtk+ bug that causes empty labels when strings
93 contain umlauts - unluckily my name features one of these so I had to write
97 - applied a big patch from Adrian Reber (adrian@lisas.de). This patch includes:
98 o compile fixes for the newer gcc releases
99 o enhancements to the commandline switches (try --help for more details)
100 o bug fixes for tX_global.c
101 - the bigNewThang (TM) is STEREO output. The Pan-Buttons now actually do what
102 you'd expect them to. Therefore your soundcard must have stereo support of
103 course but I guess in 2001 this really shouldn't be a problem, right?
104 The recorded wavfiles will now be stereo wavfiles of course.
105 Note that stereo output means double audio-bandwith, so if you tuned your
106 old terminatorX setup to smallest latency you might get clicks now. You can
107 easily fix this by increasing the buffer size in the options dialog by one -
108 this will result in the same latency as before btw.
109 - The echo effect has undergone some enhancements to profit from the new stereo
110 output. It's signal will now be mixed seperately so you can choose a different
111 stereo panorama position for the echo signal. So the new echo effect now
112 features it's own PAN-knob. This does have some sideeffects though, for more
113 details on this check the manual.
114 Additionally the echo effect now has it's own volume setting to influence
115 the dry/wet ratio of this effect.
116 - Some LADSPA effects tend to create NAN (Not A Number) float values under
117 certain conditions. This is bad as all following operations will result in
118 NANs, so there will be no audio output no more. Now I will not introduce code
119 to check for NANs as this is a waste of CPU-power, producing NANs is IMHO
120 a faulty behaviour for LADSPA plugins and it should be fixed in there.
121 Now a problem with the previous release was that the echo and lowpass effects
122 "ate" those NANs resulting in NANs in those effects' buffers. So once a NAN
123 got in there these effects caused the whole audio output to mute (forever).
124 Which is why I now introduced some code to clear the buffers in echo and
125 lowpass whenever you dis- and reenable them.
126 - The GUI does have two master vu-meters now. The turntable's still have one
127 vu-meter only. Note that the echo-signal is *not* included in the turntable's
128 vu-meter now, as it's mixed seperately.
129 - The 3DNow!-Optimizations are gone. And they'll proabably never come back as
130 I don't have time to maintain the same algorithm twice.
131 - The documentation has been updated to meet the new features. A lot of typos
132 have been fixed as well.
135 - this list may be incomplete
136 - This release brings support for LADSPA plugins. These plugins can be inserted
137 into any turntable's effect chain at any position. You can edit the the
138 effect sequence with the two tiny blue arrows. The builtin effects reside in
139 the same effect chain as LADSPA plugins, but unlike LADSPA plugins they cannot
140 be removed (nor multi-instanciated).
141 The LADSPA plugins have to "fit" into the effect chain, which is why
142 terminatorX supports *mono* plugins (plugins that have one audio-in and one
143 audio-out port) only. For the plugin's control ports, termintatorX supports
144 all HINTS except for LADSPA_HINT_LOGARITHMIC. Some control ports might be
145 hard to handle as LAPDSA control ports can have very wide value ranges. It is
146 possible to enter precise values though.
147 Get LADSPA and the CMT plugins from http://www.ladspa.org
148 All parameters for LADSPA-plugins are "sequencable parameters", so you can
149 record parameter-change events for the plugin's knobs just as for the
151 - GUI re-design to support dynamic plugin GUIs. The audiofile-display is now
152 seperated from the turntable's controls. The groups are split in to panels
153 which can be minimized if not required (orange arrow). The panels'
154 minimized-status will be saved within the set files.
155 To add a plugin effect into the turntables effect chain click on the "FX"-
156 button and choose the plugin of your choice. To get more info on the
157 plugin effects click on their panel's label.
158 NOTE: The panning-control is not working yet. It'll work as soon as stereo
160 - As always when introducing something new, the set-file file-format has
162 - The parameter-to-mouse-axis mapping has been moved from hardcoded to
163 dynamic. You can now map any parameter that's considered "mappable" to the
164 mouse-axis of your choice (for each turntable separately). This is true
165 for the control ports of LADSPA-plugins, too.
166 - Josh Steiner <joschi@eds.org> has joined terminatorX development. For this
167 release he has added some startup parameters for terminatorX, some of them
168 aiming for future MIDI support, and therefor not functional yet. Run
169 "terminatorX --help" to get more details.
170 - I know write the "manual" in SGML with the DocBook DTD. The distribution
171 contains the HTML and the postscript version. These transformation have been
172 created using James Clark's jade (DSSSL-processor) and Norman Walsh's DSSSL
173 stylesheets for DocBook.
174 - Removed obsolete "number of vtts"-option from the options dialog.
175 - Applied a patch from Josh that fixes running the soundfile editor for files
176 including a blank in their filename.
177 - New tooltips for the complete GUI.
180 - applied a tiny patch from Atsushi Yamagata <yamagata@plathome.co.jp>
181 to set locale on startup.
184 - terminatorX has a sequencer now. Warning: with the current design the
185 sequencer will correctly play back recorded events only when the buffer size
186 (of the audio device) is set to the same size as it was when recording the
187 events. I know this is annoying and I will try to find a solution to this.
188 Please take a look at the README to find out how the sequencer works.
189 - fixed a bug causing the lowpass filter produce a constant signal
190 - fixed the load file / drag'n'drop segfault bug
191 - fixed the prelisten zombie processes bug
192 - fixed the segfault on termination bug (with the audio engine running)
193 - hacked the mixer code to use 3DNow! too. This improves 3DNow! performance gain
194 from previously ~6% to more than 20% (depending on compiler optimizations)
195 - extended the set-file-format to allow storing of sequencer events. This
196 release allows loading old tX-sets too.
197 - some gui icons. Choose Text/Icon / Icon only / Text only display of these
198 icons in the Options dialog. You'll have to restart tX to see the changes
200 - "soundfile-editor support": Enter the soundfile-editor of your choice in the
201 tX-Options dialog (Still looking for an editor? Checkout Dave's Linux
202 Sound and MIDI Pages: http://www.bright.net/~dlphilp/linuxsound/).
203 Click the edit button in the Main-Panel to start your editor with the
204 turntable's soundfile - edit ;) - save and click the reload button.
205 - big endian bug fixes by Scott C. Knight <scknight@indiana.edu>
206 - --enable-benchmark will now produce a benchmark binary. This takes a set file
207 as a parameter (that set file should autotrigger all tables, else the
208 benchmark will measure how fast tX can generate zeros ;) WARNING: the
209 benchmark binary is not a usable terminatorX binary.
210 - a new dial-widget. I created this for the upcoming GUI-redesign - and decided
211 I let you debug it right now ;) If you don't want it run configure with the
212 --disable-dial switch.
213 - some gui redesign. The volume scales are now located near their corresponding
214 "flash"-widget. This release fits into very small windows - so it should be
215 usable on smaller displays as well.
216 - Adrian told me configure doesn´t have to check for glib after checking for
217 gtk+ - I guess he´s right so the glib-test has gone.
221 - implemented "sequenceable parameters" (see tX_seqpar.*). This means the
222 groundwork for the sequencer is done. Although this release does not yet
223 feature a sequencer - there's still a profit: you can now see the GUI (e.g.
224 the lowpass-freq slider) update while you change that value with your mouse in
225 dga grab mode (e.g. up/down with the default X/Y-Control settings).
226 - fixed (libmmx) mmx.h to work with gcc 2.95 and above
227 - fixed compilation problems for big endian machines. still runtime probs
229 - fixed configure-script as the new bash complains about == in string compares
230 - fixed some gui segfaults
231 - added an ugly GNOME-mimetype installer. This installs the ".tX"-mime type, an
232 terminatorX-application icon and a ".tX"-icon. I could use some hints on how
233 I could make automake install that instead of an extra script.
235 - added Drag'n Drop support. Works with the great gmc. Drop an audio file over
236 the filename-button or the wavdisplay of a turntable to load it into that
237 table. Drop an audiofile over the "Add Turntable" Button to create a new
238 turntable and load that file into that turntable. Drop a tX-set file over the
239 "Load Set" button to load the set.
242 - fixes the load_piped() compilation error if you use neither sox nor mpg123.
243 Note that you have no "pre-listening" without mpg123 for mp3s and no
244 "pre-listening" for any other file without sox.
247 - Yet another redesign ;) Oh well this project moved from c++/multithreaded
248 to c++/singlethreaded, to c/multithreaded and now, finally, back to
249 c++/multithreaded. This shows quite some foresight, I'd say ;)
250 - Due to the redesign I had to change a lot (everything?) again so this document
251 can impossibly hold all changes. but let's see:
252 - tX now uses floats instead of doubles for a lot of parameters. Therefore the
253 old .terminatorXrc.bin is now called .terminatorX3rc.bin to allow parallel
254 use of older releases. But you'll have to configure the new release again
255 the first time you run it.
256 - tX now supports an unlimited no of turntables. The only limit is your display
258 - Each of these turntables has their own pitch / volume settings and a
259 dedicated lowpass and echo effect section.
260 - You can now map mouse motion to a function of your choice (scratching/
261 volume/cutoff/echo-feedback and nothing)
262 - Recording will now happen straight to disk. You'll have to specify a filename
263 before you start recording.
264 - You can sync the turntables to one master turntable.
265 - There are two master settings for pitch and volume available to modify all
266 turntables. The turntable pitch is relative to the master pitch.
267 - You can save a complete set (of turntables and settings) to a .tX set file.
268 The audiofile data will *not* be saved within that file, but it'll contain
269 the absolut filename to these files. I know this makes the act of exchanging
270 sets over the net more complex so if somebody wants to code set files with
271 integrated audio data... ;)
272 - The way audiofiles are loaded has been redesigned too: the builtin wav
273 routines, the sox support and mpg123 are no longer connected. This means
274 you can use mpg123 support without sox support and still have the builtin
275 wav routines enabled. If you have the builtin wav reader and sox enabled, tX
276 will try try to use the builtin routines first, and if they fail sox will be
277 used as a fallback which is of course slower as you know... There's some
278 support for Benno Senoner's brilliant 3.2-mmap() patch but the patch still
280 - You can now select which parameter to map to a mouse axis.
281 - experimental 3DNow! support (works with gcc < 2.95 only)
282 - tX-windows now have an icon, thanks Michael!
285 - implemented 2D-Scratching ;) You can now use the other axis of your mouse
286 two modify the cutoff frequency of the lowpass filter (if enabled). The
287 resonance factor can be set via the slider underneath "LP Filter". Seems
288 to eat quite some CPU power though...
289 - Updated THANKS, AUTHORS
290 - as most people seem to use sox/mpg123 anyway and as I still get "I want mp3"
291 emails I changed the configure script slightly: It now automatically enables
292 the use of sox and mpg123 if these are available. If you still want 'em good
293 old 16Bit/44.1Khz/Mono builtin routines you have to specify --enable-wavonly
294 with your configure cmdline.
295 - Prepared the tarball for the Win32 port. You can now compile tX with cygwin
296 and the Makefile.cygwin in the src directory if you have all the required
297 libs (gtk, pthreads etc...). The resulting exe will run BUT is completely
298 unusable for now... Stou Sandalski <tangui@cell2000.net> and I are planning
299 to make it usable in the future.
300 - The About-Dialog now contains some info on how the binary was compiled
303 - Optimized audio-rendering code for speed (might run on some machines
304 with smaller buffsize (-> lower latency) than pre-3.1) - Hey, tX now uses
305 less than 10% CPU (says kpm) with mixing enabled on my i586-200MMX machine!!
306 - "fixed" stdout-output. Due to the pipe-buffering realtime schratching can
307 not be considered usable for now :(
308 - Added config option --enable-scheduler, which will cause the terminatorX
309 engine-thread to run with FIFO scheduling policy and highest priority. This
310 might enable some machines to use smaller buffsizes. It requries root
311 privileges though - either run terminatorX as root - or make terminatorX
312 suid root WHICH IS A BAD IDEA FOR MULTI-USER SYSTEMS IF OTHER USERS CAN
313 ACCESS THE BINARY ;) You only have to think about this when you experience
314 buffer underruns with your desired latency. And it might not even help...
315 - Rehacked the de-clicking (fading) code. The old one tried to be much more
316 intelligent - and failed fading out the signal sometimes. The new code
317 is much simpler (faster) and is much more reliable.
318 - added common sense to the warp feature (f-key in scratch mode). The warping
319 speed is still connected to the mouse speed but it's now adjusted to the
320 sample size as well: you can warp through any sample completely with the same
322 - added debug configure switch. Enables (very few) debug messages for now. I
323 decided not to enable the old V2.X messages as they are sent to stdout, which
324 would sound pretty strange to people who use the stdout-option.
327 - Fixed Adrian's name in the THANKS file. Sorry, Adrian.
328 - Corrected Makefile.am for license.c that did not build correctly on some
329 systems - Thanks to Michael Pruett <mikep@ugcs.caltech.edu>
332 - fixed a bug that caused terminatorX to crash without --enable-sox or
336 - Changed everything ;)
337 - switched from C++ to C for gtk's sake
338 - switched back two multithreading
339 - implemented new gtk+ gui and dialogs
340 - new mouse-sampling code now uses DGA's DirectMouse
341 - implemented "initalizing"-support for XInput devices.
342 - new (alpha) "pre-listening" feature in scratch/loop dialogs
343 - hacked vtt for click-free audio. Might be problematic with big
344 kernel level buffersizes but scratching with big buffsize is no
346 - options are now stored in ~/.terminatorXrc.bin automatically (on exit)
347 as well as windowsize and the last used filenames
348 - terminatorX now comes with a configure script - no more Makefile hacking
349 required (nor a good idea ;) )
350 - new wavdisplay-widget update frequency is now configureable
351 - new position-display is much more visible which allows more precise
353 - new mute-feature allows you to silence the scratch-playback completely
354 while the loop keeps playing (press either <m>-key or right mouse-button.
355 - support for mouse buttons:
356 o 1. (left) button: same as <SPACE>, do scratch
357 o 2. (right) button: mute scratch
358 o 3. (middle) button: stop
359 - wrote support for sox and mpg123. This enables terminatorX to read close
360 to any audiofile. You need to have sox and mp3 and this feature (as it is
361 still alpha) needs to be enabled via configure-switches see INSTALL
362 - licmak now is an awk script. Thanks Christian! I was also received two perl
363 scripts (Thanks, guys!) but I now use the awk script as it is the smallest.
364 - introduced <F>-key to "warp" through scratch-sample (just check it out)
365 - dropped commandline arguments
366 - dropped old X-Code + Mouse warping madness
367 - bug fixes (less than bug introduces though ;) )
371 - implemented a time counter
372 - licmak now finally is what it should be: a perl script (licmak.pl)
373 it was contributed by: Adam Sjøgren <asjo@diku.dk>. Thanks!
376 - X-Window background fixed
377 - wavfile overreading fixed by Andrew C. Bul+hac?k (acb@zikzak.net)
378 - Using portable type definitions now where required. If you don't
379 have a <sys/types.h> on your system and your machines type sizes
380 equal those of an X86-machine you can specify -DUSE_X86_TYPES in
381 Makefile to compile without <sys/types.h>
382 - Slight change in audiodevice-handling that fixes improper buffsize
383 settings on some soundcards (e.g. GUS)
384 - Implemented "keep device open"-feature. Needs to be enabled via the
385 -DKEEP_DEV_OPEN switch in Makefile
386 - Added some comments to the Makefile for easier editing
387 - Added Big Endian support. Use -DBIG_ENDIAN_MACHINE for big endian hosts
388 like ultrapenguin suns or linux ppc. There's also -DBIG_ENDIAN_AUDIO
389 for big endian audio hardware (rare?) available, although proabably
390 nobody will need this.
391 - Changed mix behaviour: Mix is now automatically turned on on startup if
392 the user has specified a proper loop file. (with the --loop or -l switch)
393 - New mixing routine. You can now set the loop to scratch volume ratio with
394 the cursor keys (left/right). If you modify the volumes while recording
395 these action's will not be recorded. Saving happens with the currently
397 - Fixed README-Bug said <m> instead of <x>
400 - first released version
401 - added colors. more standard use of X11.
402 - added loop support.
403 - added statusbar with mode/status display
404 - added commandline options and help (on usage and keys)
405 - added raw/mixed save scratch feature
406 - added licmak to include license into binary
407 - new handling of XAutoRepeat, only turned off now when SPACE pressed.
408 - modified wave display (faster + nicer + incorrect (who cares anyway))
409 - Makefile fixed by Adrian Reber (adreit00@fht-esslingen.de)
415 - added recording, playback of recording functionality
418 - moved from multithreaded to singlethreaded
424 - no more position display due to pthread/X probs
430 - accelerating vtt via sinus
