# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
3      * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14        - minor fix in configure for mmsystem.h detection on MinGW
15        - Windows: look for editor plugins and Fantasia using base
16          directory of liblinuxsampler dll
17        - configure script fix: removed unconditional use of SSE
19      * general changes:
20        - bugfix: on some POSIX systems instrument editor plugins refused to
21          load as we used a non-portable Linux specific struct field
22          (fixes bug #70, patch by Ronald Baljeu)
23        - fixed endless loop which occured when loading an instrument editor
24          plugin DLL on Windows systems failed
25        - fixed memory leaks that occurred when liblinuxsampler was unloaded
26        - optimized the SynchronizedConfig class so it doesn't wait
27          unnecessarily long after an update
28        - added support for notifying instrument editors on note-on / note-off
29          events (e.g. to highlight the pressed keys on the virtual keyboard
30          of gigedit)
31        - added support for triggering notes by instrument editors (see above)
32        - be verbose on DLL load errors (on Linux)
33        - fixed di-harmonic triangle LFO implementation (this LFO implementation
34          is only used by very few systems, most pick the int math
35          implementation, which is usually faster)
36        - fixes for audio drivers with varying buffer sizes
37        - experimental support for running LinuxSampler as a DSSI, LV2 and
38          VST plugin
39        - notification events for stream/voice count statistics are now sent
40          only when there are actual changes
41        - added memory ordering constraints to improve stability on
42          multi-core and multi-cpu systems
43        - maximum voices and disk streams can now be altered at runtime
44        - fixed CPU feature detection on x86_64 (maybe fixes #108)
45        - automatic stacktrace mechanism is now turned off by default and can
46          be switched on by command line option "--stacktrace" (the automatic
47          stacktrace mechanism seems to be broken on most systems at the moment)
48        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49          a pointer to the launched InstrumentEditor object
50        - added optional 3rd party user data parameter for following
51          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52          InstrumentEditor::Launch(),
53          InstrumentManager::LaunchInstrumentEditor()
54        - theoretical fix: made SynchronizedConfig follow C++0x memory
55          model more strictly
56        - fixes for using large audio device buffers
58      * audio driver:
59        - removed the nonsense audio channel constraint (which was hard coded to
60          max. 100 audio channels) for most audio drivers
61        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62          opposed to the LSCP specs
63        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64          reflected the wrong value
65        - fixed a memory management bug in ASIO driver
66        - Makefile fix: JACK_CFLAGS wasn't used
67        - JACK: use jack_client_open instead of the deprecated
68          jack_client_new
69        - added (experimental) CoreAudio driver
70        - applied old fixes to the ASIO driver that were included in the
71          previous binary release but accidentally never committed to CVS
72          (fixes #117)
73        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74          win64)
75        - VST: added support for sample rate and buffer size changes
76        - VST: close editor (Fantasia) when the VST is removed
77        - VST: avoid opening Fantasia more than once for each VST instance
78        - VST: export main function as "main" on Linux too (fix for
79          energyXT)
81      * MIDI driver:
82        - added JACK MIDI driver
83        - dispatch bank select as ordinary CC as well, the user might seriously
84          want to (mis)use it for some purpose ("fixed" in all current MIDI
85          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
86        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
87          CoreMidi or AU
88        - fixed mingw-w64 compilation error in MME driver
90      * instruments database:
91        - avoid time consuming samples scanning when adding instruments
92          to the instruments database
93        - added support for handling lost files in the instruments database
94        - Implemented option for adding instruments in separate directories
95          in the instruments database
96          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
97        - work-around for missing fnmatch function on Windows to make
98          instrument database compilable
99            - added instrument database support on Windows
100              works with both standalone mode and VST plugin.
101              the instruments DB file is located in
102              %USERPROFILE%\.linuxsampler\instruments.db which allows different
103              databases for each windows user
105      * Gigasampler format engine:
106        - fixed a memory leak that could happen when a channel was deleted
107          while notes were playing
108        - made it possible to load an instrument even if the audio thread
109          isn't running
110        - added partial support for the "Controller Triggered" MIDI rule,
111          enough for piano gigs with pedal noise samples
112        - minor fix: only mark FX sends as being modified if really the
113          respective FX send MIDI controller was used
114        - added support for GM global device volume SysEx message
115          (can be selected at compile time to either apply globally to the
116          whole sampler [default] or only to the sampler channels that are
117          connected to the respective MIDI input port the SysEx message arrived
118          on)
119        - bugfix: notes triggered at position 0 in the audio buffer were
120          sometimes wrongly killed in the same buffer, causing no sound to
121          be played
122        - added support for chromatic / drumkit mode Roland GS Sysex message
123          which is usally used to switch a part between chromatic sounds and
124          drumkit sounds (as opposed to their common default setting of MIDI
125          part 10 being a drumkit part and all other ones chromatic parts), in
126          LS however one can switch between the first 16 MIDI instrument maps
127          defined for the sampler
128        - made it possible to create multiple sample channels even if the
129          audio thread isn't running
130        - fixed crash when removing channel with active voices (#116)
131        - bugfix: on sample reference changes (instrument editor), only
132          un-cache the respective sample if it's really not used by any
133          sampler engine anymore
134        - re-cache samples in case they were changed by an instrument editor,
135          e.g. when a sample was added while playing (#82)
136        - fixed hanging notes which occured when note-off event had the exact
137          same time stamp as the voice's note-on event and occured both in the
138          same audio fragment cycle (fixes bug #112)
139        - added support for the "fine tune" and "pitch bend range"
140          instrument-level gig parameters
141        - fixed minor artifacts in pitch bend handling
142        - added support for GS Reset SysEx message
143        - allow gig files to use unlimited downward pitch shifting
144        - added a limit check for upward pitch shifting
145        - bugfix: sometimes, when playing a note twice fast, the second
146          note was silent
148      * LSCP server:
149        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
150          react on MIDI data arriving on certain sampler channels (so far only
151          Note-On and Note-Off events are sent via this LSCP event)
152        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
153          react on MIDI data arriving on certain MIDI input devices (so far only
154          Note-On and Note-Off events are sent via this LSCP event)
155        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
157        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
158          frontends to send MIDI messages to specific sampler channel
159        - added two additional fields to GET FILE INSTRUMENT INFO command -
161        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
162          was incorrect
163        - Optimized the retrieval of the MIDI instrument mappings
164        - added new LSCP command "SET VOICES" to globally alter the maximum
165          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
166          be triggered respectively
167        - added new LSCP command "SET STREAMS" to globally alter the maximum
168          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
169          which will be triggered respectively
170        - bugfix: retry if "select" returns EINTR (this fixes a crash when
171          a gigedit file dialog is opened)
172        - close all connections when LSCPServer is deleted
173        - hard close of all sockets on exit
174        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
175          driver
177      * Bug fixes:
178        - fixed a crash which occurs when removing a sampler channel waiting
179          to start instrument loading after another channel
180        - fixed a crash which occurs when removing a sampler channel with
181          instrument loading in progress (bug #113)
182        - fixed termination caused by uncaught exception when adding MIDI
183          instrument with PERSISTENT load mode
184        - fixed possible iterator invalidations when resetting the sampler
185        - fixed memory leaks when issuing the following LSCP commands:
190        - fixed possible compilation error when sqlite is not present
191        - fixed orphaned pointers when setting maximum voices limit (bug #118)
192        - fixed crash when changing the audio output device of a sampler
193          channel with loaded instrument and start playing notes
194        - fixed endless loop in Engine::SuspendAll() (bug #120)
195        - fixed a low-level atomic load function that was broken on 64-bit
196          PowerPC, which probably could cause crashes on that platform
197        - fixed a memory management error which could cause a crash when a
198          plugin was unloaded
199        - bugfix: two private structs had the same name, which could cause
200          problems if the linker chose the wrong constructor
203    Version 0.5.1 (6 December 2007)
205      * packaging changes:
206        - added autoconf checks for pthread library
207        - added autoconf check for pthread bug found on certain NPTL-enabled
208          glibc versions (see Gentoo bug report #194076)
209        - added autoconf checks for MS Windows
211      * general changes:
212        - bugfix: the thread used by an editor plugin didn't die when the
213          editor closed
214        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
215          out all the space. operator--() did not apply size_mask after
216          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
217          order to avoid problems with the _NonVolatileReader functions.
218        - bugfix: Stream.h: added a missing divide by BytesPerSample in
219          GetWriteSpace(). Since this function is currently only used in
220          the stream's qsort() compare function, it didn't trigger any
221          bugs.
222        - Resampler.h, Synthesizer.h: cubic interpolation now works in
223          24bit mode too. Faster method to read 24bit words on little
224          endian machines (x86): replaced 3 byte reads + shifts with a 1
225          unaligned 32bit read and shift
226        - experimental support for MS Windows (MIDI input via MME, AUDIO
227          output via ASIO)
228        - made handling of SIGINT signal (Ctrl-C) a bit more robust
229        - support for monitoring the total number of active disk streams
230          (new LSCP commands: GET TOTAL_STREAM_COUNT,
233      * AUDIO driver:
234        - added Windows ASIO low latency audio driver
236      * MIDI driver:
237        - added MME Windows MIDI driver
239      * LSCP server:
240        - added support for Windows style path / filenames, however with
241          forward slash path separators instead of backslash
242          (i.e. "C:/foo/bar.gig")
243        - allow naughty liblscp to send non-string device parameters within
244          apostrophes as well
245        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
246          "LIST FILE INSTRUMENTS <file>" and
247          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
248          about an arbitrary instrument file on the system where the sampler is
249          running on
251    Version 0.5.0 (15 October 2007)
253      * packaging changes:
254        - config.h is not going to be installed along with liblinuxsampler's
255          API header files anymore
256        - only the API relevant header (and source) files will be exported to
257          the Doxygen API documentation (explicitly listed in Doxyfile.in)
258        - added completely new XCode project files for Mac OSX which is now
259          capable to execute our autoconf environment, thus no need anymore
260          to maintain the compile time configuration file (osx/version.h) for
261          OSX manually (patch by Toshi Nagata)
262        - fixed buggy boolean --enable-foo / --disable-foo configure script
263          parameters
264        - global.h now only covers global definitions that are needed for the
265          C++ API header files, all implementation internal global definitions
266          are now in global_private.h
267        - atomic.h is not exposed to the C++ API anymore
268        - no need to include config.h anymore for using LS's API header files
269        - fixed warnings in API doc generation
271    * general changes:    * general changes:
272      - replaced the old, confusing MIDI program change mechanism by a      - replaced the old, confusing MIDI program change mechanism by a

297      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
298        - Implemented new, improved notification system
299        - fixed compilation errors regarding OSX
300          (patch by Toshi Nagata)
301        - implemented instruments database
302        - added support for escape sequences to the instruments database
303        - added highly experimental support for on-the-fly instrument editing
304          within the sampler's process (by using instrument editor plugins),
305          you'll notice the new "Registered instrument editors:" message on
306          startup, added a new LSCP command:
307          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
308          to spawn a matching instrument editor for the instrument on the
309          given sampler channel, the plugin path can be overridden at compile
310          time with ./configure --enable-plugin-dir=/some/dir
311        - added experimental code for synchronizing instrument editors hosted
312          in the sampler's process to safely edit instruments while playing
313          without a crash (hopefully) by either suspending single regions
314          wherever possible or if unavoidable whole engine(s)
315        - fixed several issues in fundamental "Thread" class: set scheduling
316          policy and priority on thread level, set a minimum stack size for
317          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
318          threads simply inherited properties of starting thread instead of
319          setting their own policy and priority
320        - minor fix in our automatic stack trace mechanism on crashes, the
321          main process did not wait for the stack trace process to finish
322          its output
323        - fixed some minor memory leaks
324        - reenabled assembly features support, at the moment only for
325          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
326        - minor assembly fix in x86 features detection (don't use the PIC
327          register, to avoid relocations in the text segment at runtime)
328        - POSIX callback functions of Thread.h are hidden
330    * MIDI driver:    * MIDI driver:
331      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

350        even if sustain is 100%        even if sustain is 100%
351        - more EG fixes: the level could sometimes go below zero and cause
352          noises or crashes
353        - minor fix of EGDecay (patch by Toshi Nagata)
354        - fixed compiler error when --enable-override-filter-type was
355          supplied to the configure script (fixes #46)
356        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
357          instead of a fix value
358        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
359          127 (solo mode) only kill voices if the respective mode really
360          changed
362      * LSCP server:
363        - fixed compile time error for old Bison versions
364          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
365        - parser now supports extended ASCII character set
366          (up to ASCII code 255, i.e. includes now umlauts and accents)
367        - filename arguments in LSCP commands now allow to use escape
368          sequences, that is directly literal as one of: \', \", \\, \n, \r,
369          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
370          code value like \xf2) (fixes bug #24)
371        - the following LSCP commands now also support escape sequences for at
372          least one of their text-based parameters (i.e. name, description):
379        - returns verbose syntax errors (line and column where syntax error
380          occured, the unexpected character and the actually expected, possible
381          character(s), the latter only if less than 5 possibilities)
382        - made sure that LSCP syntax is not affected by gigedit locale
383          settings
384        - bugfix regarding strings parameter lists: all comma separated lists
385          of strings were treated as being one string containing commas
386          (fixes #57)
388    * Bug fixes:    * Bug fixes:
389      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
390      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
391        channel audio output device"        channel audio output device"
392        - fixed a crash which occurs when reassigning the same engine
393          on a sampler channel with connected MIDI device
394        - fixed a crash which occurs when changing the number of ports of a MIDI
395          device connected to a sampler channel to number less then or equal
396          to the index of the port to which the sampler channel is connected.
397        - The previous bindings were not been disconnected when altering
398          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
399          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
400        - The active stream/voice count statistic was incorrect.
401        - notification events were not been sent for some sampler
402          channel changes
403        - added default min and max values to restrict the number of allowed
404          audio output channels and MIDI input ports
405        - the connection to the PCM interface is now closed when destroying
406          an audio output device
