8 * Moving from old deprecated Qt3'ish custom event post handling
9 into regular asynchronous signal/slot strategy. (EXPERIMENTAL)
10
11 * Sampler channel and instrument file requester support for
12 other than GIG engine instrument files (*gig; *.dls) has
13 been added, making roads for the newer SFZ and SF2 engines
14 instrument files (*.sfz; *.sf2).
15
16 * General standard dialog buttons layout is now in place.
17
18 * Initial widget geometry and visibility persistence logic has
19 been slightly revised as much to avoid crash failures due to
20 wrong main widget hidden state.
21
22 * General source tree layout and build configuration change.
23
24 * Automatic crash-dump reports, debugger stack-traces (gdb), back-
25 traces, whatever, are being introduced as a brand new configure
26 option (--enable-stacktrace) and default enabled on debug build
27 targets (--enable-debug).
28
29 * Attempt to fix broken instrument list model/view on Qt >= 4.6.
30
31 * Device parameter spin-box default maximum has been set higher:
32 now at a magic 24-bit limit (16777216) instead of older 16-bit
33 (65536), possibly fixing bug #136.
34
35 * LADISH Level 1 support has been added: SIGUSR1 signal trap
36 just makes it a shortcut to File/Save.
37
38 * MIDI Device Status menu is disabled when no MIDI device exists;
39 a menu separator has been added.
40
41 * Window manager's close button was found missing from the Devices
42 and Instruments widgets when on Qt >= 4.5, now fixed.
43
44 * MIDI activity indicator on channel strips and MIDI device status
45 widgets is now implemented as a flashing green LED, instead of a
46 lame green solid background :).
47
48 * Global configuration state is now explicitly saved/committed to
49 disk when View/Options... dialog changes are accepted and applied.
50
51 * Czech (cs) translation added (by Pavel Fric).
52
53
54 0.2.2 2009-08-01 New release cycle.
55
56 * Russian (qsampler_ru.ts by Alexandre Prokoudine) makes it as
57 brand first translation delivered. Thanks and welcomes whom
58 ever may follow ;)
59
60 * Converted obsolete QMessageBox forms to standard buttons.
61
62 * Added support for runtime max. voices / disk streams setting
63 (accessible from the "Options..." dialog). Those fine tuning
64 settings will be saved in case the user modified them and
65 automatically restored to the sampler when reconnecting to
66 a sampler the next time.
67
68 * Grayed/disabled palette color group fix for dark color themes.
69
70 * Fait-divers: desktop menu file touched to openSUSE conventions.
71
72 * Due to some trouble with newer Qt >= 4.4 applications regarding
73 font size configuration, a new global user option is now available
74 to the rescue: View/Options... /Display/Other/Base font size
75 (default none).
76
77 * Attempt to load Qt's own translation support and get rid of
78 the ever warning startup message, unless built in debug mode.
79 (transaction by Guido Scholz, while on qsynth-devel, thanks).
80
81 * Only one application instance is now allowed to be up and
82 running, with immediate but graceful termination upon startup
83 iif an already running instance is detected, which will see its
84 main widget shown up automatically (Qt/X11 platform only).
85
86 * Messages file logging makes its first long overdue appearance,
87 with user configurable settings in View/Options.../Server/Logging.
88
89 * Bugfix in sampler channel dialog, driver combo boxes' content were
90 screwed.
91
92 * Automatically add & remove channel strips as they were removed
93 e.g. by other frontends.
94
95 * Refresh device management dialog when device informations changed,
96 e.g. on changes caused by other frontends
97 (fixes segfault on device changes)
98
99 * Implemented MIDI device activity windows, selectable from the
100 "View" main menu.
101
102 * Implemented MIDI activity indicator on channel strips.
103
104 * Added FX Sends Dialog to Channel Strips.
105
106 * Color pallete fix for the instrument name display in channel
107 strip, particularly notorious on Mac OS X builds.
108
109 * Added dialog when the application exits which lets the user
110 decide whether to keep the LinuxSampler running or not.
111
112
113 0.2.1 2007-12-06 Qt4 migration was complete.
114
115 * Added recent new support of libgig for retrieving instrument
116 names in avery fast way. If libgig provides this feature, then
117 the respective name retrieval setting in qsampler is enabled by
118 default.
119
120 * The current selected/activated channel-strip is now visually
121 evident while in the application workspace (highlighting).
122
123 * Make View/Menubar and Toolbar shortcuts accessible even though
124 the main menu and toobar are not visible.
125
126 * Audio routing table is initially hidden in the dialog, when
127 creating a new sampler channel.
128
129 * README requirements and configuration notes update.
130
131 * Disable OK button in sampler channel form and MIDI instrument
132 form if no valid engine is selected (to avoid bothering newbie
133 users with confusing LSCP syntax errors when using the UI the
134 first time).
135
136 * Fixed creation of devices (don't try to set device parameters
137 which the user did not touch in the device creation dialog).
138
139 * Added Windows file path support.
140
141 * Fixed win32/qmakefile and win32/config.h so that it compiles
142 under win32.
143
144 * Qt4 port of the application.
145
146
147 0.1.5 2007-10-15 Five months later a fifth is heard.
148
149 * Added support for LSCP escape sequences to allow loading and
150 mapping instrument files with special characters in their
151 filename, as well as special characters for instrument names
152 and instrument map names (requires LSCP v1.2 on sampler side).
153
154 * Added new button "Edit" to the channel strips, which probably
155 does exactly what you think it does: it opens an appropriate
156 instrument editor application; the channel instrument editor
157 tool is also accessible from the main menu and toolbar.
158
159 * Application icon is now installed to ${prefix}/share/pixmaps;
160 application desktop entry file is now included in installation;
161 spec file (RPM) is now a bit more openSUSE compliant.
162
163 * Crash fix on double-clicking on a empty instrument list.
164
165
166 0.1.4 2007-05-04 Almost another year has gone by.
167
168 * Channel button colors have changed: yellow for mute and
169 cyan for solo is now the rule, but note that this color
170 highlighting is only rendered on some widget styles.
171
172 * Master sampler volume slider/spinbox combo is now featured.
173
174 * Initial support for sampler channel FX sends, while saving
175 the session state, only at code-level.
176
177 * Sampler channel setup dialog does not mandate for valid nor
178 existing instrument file name.
179
180 * Revised error verbosity in general and on session load/save;
181 hour-glass wait cursor is now displayed on session load/save;
182 keyboard shortcuts changed on MIDI instruments view context;
183 improved channel strip arrangement on session open/load;
184 instrument map entry removal confirmation (as optional);
185 corrected some tooltip text strings.
186
187 * Most top-level widgets were missing the normal-widget flag,
188 which were causing some sticky size behavior while on some
189 window managers.
190
191 * Added preliminary MIDI instrument mapping support; now
192 with an instrument list widget and editing capabilities;
193 MIDI instrumeent map program numbers are now displayed in
194 the range 1-128, instead of the internal 0-127.
195
196 * GPL address update.
197
198
199 0.1.3 2006-06-01 Its been a long year isn't it?
200
201 * Changed deprecated copyright attribute to license,
202 on qsampler.spec (RPM).
203
204 * Added configure support for x86_64 libraries (UNTESTED).
205
206 * Optional specification of alternate liblscp and libgig
207 installation paths have been added to configure command
208 arguments (--with-liblscp, --with-libgig).
209
210 * Whenever the listing of actual instrument names is not an
211 option (e.g. due to lack of libgig support), the whole
212 number of selectable instrument items is now being graciously
213 increased from just the bare 8 (eight) right up through 100
214 (one hundred), on the sampler channel setup dialog.
215
216 * The selection buttons, on the right of the Instrument, Audio
217 and MIDI devices combo-boxes, on the sampler channel dialog,
218 are now expected to be a little better looking than it was
219 before, at least for those Mac OS X eyes.
220
221 * Minor fixing on the initial messages dock-window height.
222
223 * Audio output channel routing configuration finally hits
224 the sampler channel dialog, at last! (EXPERIMENTAL).
225
226 * All widget captions changed to include proper application
227 title name prefix.
228
229 * Attempt to bring those aging autoconf templates to date;
230 sample SPEC file for RPM build is now being included and
231 generated at configure time.
232
233 * Set to use QApplication::setMainWidget() instead of
234 registering the traditional lastWindowClosed() signal
235 to quit() slot, just to let the -geometry command line
236 argument have some effect on X11.
237
238 * Added MUTE/SOLO buttons to individual channel strips.
239
240 * Fixed compilation error which occured when Qt was
241 compiled with -no-stl.
242
243
244 0.1.2 2005-06-23 Even minor workings needs a rest.
245
246 * Fixed output disability when messages limit option is
247 turned off (thanks to Wolfgang Woehl for spotting this
248 one, while on qjackctl).
249
250 * Added CHANNEL_INFO event feedback notification handling;
251 minor stream/voice usage auto-refresh cycle optimization.
252
253
254 0.1.1 2005-06-12 The mantra of bugfixes.
255
256 * New improved and full-featured application icon, thanks
257 to Christian Schoenebeck design.
258
259 * Fixed refresh cycle of channel strips that are found
260 in an error state, which was preventing correct channel
261 info updates.
262
263 * Device configuration now accessible on toolbar. Added
264 buddy text label to device port/channel combobox on the
265 device dialog.
266
267 * Include libgig version info on command line request (-v).
268
269 * Minor configure and Makefile install fixes, as Debian and
270 Mac OS X specialties. Also, install does the right thing
271 with target file modes (thanks to Matt Flax and Ebrahim
272 Mayat, for pointing these out).
273
274
275 0.1.0 2005-05-23 Device configuration breakthrough.
276
277 * Device configuration is now complete (EXPERIMENTAL).
278
279 * [bug #9] Fixed for a LSCP command syntax convention
280 consistency, regarding the enumeration of available
281 sampler engines, Audio and MIDI drivers.
282
283 * [bug #13] Update instrument names list when a new
284 instrument file is select on the channel setup dialog.
285
286 * Show appropriate message in channel strip while loading
287 an instrument.
288
289 * Show libgig version in About box (in case libgig is used).
290
291
292 0.0.5 2005-03-04 Fifth alpha-release.
293
294 * Fixed device driver type channel information gathering,
295 which was severely flawed, dropping all channel session
296 configurations to the default audio driver type (which
297 is ALSA) unexpectedly.
298
299 * Channels are now properly renumbered when saving to a
300 session LSCP script, assuming that it should be always
301 loaded from scratch (i.e. zero channels).
302
303 * Disabled MIDI port setting on channel dialog, and on
304 session file save, as its use is still troublesome.
305
306 * Added new menu and toolbar option: Reset All Channels.
307
308 * Channel setup changes are now properly filtered, as for
309 only those settings that are actually changed gets applied;
310 change information are now also posted to messages window.
311
312 * Drag-and-drop of either session files (LSCP scripts) or
313 instrument files (GIG) are now supported. Multiple files
314 drop is allowed, but it only makes sense for instrument
315 files, each one prompting to create a new sampler channel.
316
317 * Drag-and-drop to an existing channel strip is now also
318 featured, allowing the in-place change of the channel
319 sampler instrument file.
320
321 * Actual instrument names are now optionally retrieved
322 from the instrument file, even though libgig is available,
323 avoiding excessively annoying load times while on the
324 channel dialog, when huge instrument files are selected.
325
326 * Set to ignore the SIGPIPE ("Broken pipe") signal, where
327 available, as the default handler is usually fatal when
328 a JACK client is zombified abruptly.
329
330 * Messages window limit is now enforced only when the line
331 count exceeds in one third the user configured line count
332 maximum; if Qt 3.2.0+ is in use, the QTextView widget is
333 otherwise set to the optimized Qt::LogText format.
334
335
336 0.0.4 2004-11-19 Fourth alpha-release.
337
338 * Instrument index selection now made via combo box widget;
339 actual instrument names are now properly retrieved from
340 the instrument file, provided if libgig is available.
341
342 * Sampler channels strips are just created if, and only if,
343 the respective channel setup dialog is actually accepted,
344 following common user-interface guidelines.
345
346 * Almost complete rewrite of sampler channel strips internal
347 control structures.
348
349 * Sampler reset command action added to menu and toolbar.
350
351 * MIDI channel selection is now a dropdown list, allowing
352 the explicit selection for "All" channels input per sampler
353 channel (omni mode).
354
355 * Channel strip display glass effect has changed background
356 color to black (was green), being now an user option.
357
358 * Minor configure fixes.
359
360
361 0.0.3 2004-07-06 Third alpha-release.
362
363 * Mon-modal intrument file loading and status support.
364
365 * Effective MIDI input port setting on channel dialog,
366 and on session file save.
367
368 * Channel dialog gets sensible engine and driver defaults
369 on create time.
370
371 * Implied channel reset on successful instrument load.
372
373
374 0.0.2 2004-06-15 Pre-revolutionary release.
375
376 * The channel context menu is also accessible by right-clicking
377 over the empty workspace area.
378
379 * Added small wait event loop on qsamplerMainForm::stopServer(),
380 so let local server terminate gracefully and stabilize, and
381 avoiding a probable segfault on exit, which was preventing the
382 correct salvage of settings and configuration.
383
384 * Maximum channel volume percent setting is now a global option,
385 provided to override the default (which is 100%).
386
387 * Client/server transaction timeout option upper limit has been
388 increased from 5000 to 60000 milliseconds.
389
390 * A channel context menu is now featured, by right-clicking over
391 each sampler channel strip.
392
393 * Commented SET CHANNEL MIDI_INPUT_PORT command from
394 qsamplerMainForm::saveSessionFile(), it has no effect.
395
396 * Insert a n #include <unistd.h> on qsamplerMessages.cpp, between
397 a #if !defined(WIN32) clause.
398
399 * An initial non zero value (0.8) is now set for volume of every
400 new sampler channel strip.
401
402 * The order to load/save and setup channel settings is now as
403 suggested in the following lines:
404
405 SET CHANNEL AUDIO_OUTPUT_TYPE ...
406 SET CHANNEL MIDI_INPUT_TYPE ...
407 SET CHANNEL MIDI_INPUT_CHANNEL ...
408 LOAD ENGINE ...
409 LOAD INSTRUMENT ...
410 SET CHANNEL VOLUME ...
411
412
413 0.0.1 2004-06-05 Primordial alpha release.
