3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18          note (in this implementation of the sampler its simply hard routed to
19          the 1st effect send of the sampler channel, no matter what the actual
20          effect type is)
21        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22          note (in this implementation of the sampler its simply hard routed to
23          the 2nd effect send of the sampler channel, no matter what the actual
24          effect type is)
25        - implemented support for internal LADSPA effects
26    
27      * Gigasampler format engine:
28        - implemented the "round robin keyboard" dimension
29        - fixed round robin and random dimensions for cases when number of
30          dimension zones is not a power of two
31        - made round robin use a counter for each region instead of each
32          key
33    
34      * SFZ format engine:
35        - Initial implementation (not usable yet)
36        - added support for v2 multiple stage envelope generators
37        - added a fine-tuned v1 envelope generator instead of using the
38          one from the gig engine
39        - fixed memory leak and memory handling errors
40        - added support for trigger=first, trigger=legato and sw_previous
41        - allow non-numerical key values ("C#4" for example)
42        - "key" opcode now sets pitch_keycenter too
43        - fixed error when unloading instrument with same sample used by
44          multiple regions
45        - added some opcode aliases, like loopmode for loop_mode, to be
46          more compatible
47        - added support for trigger=release and rt_decay
48        - added support for off_mode=normal
49        - added support for random, seq_position, seq_length and volume
50        - added v1 LFO opcodes to parser (no support in engine yet)
51        - added support for amp_veltrack and amp_velcurve_N
52        - fine-tuned the default velocity curve
53        - added support for transpose
54        - fixed crash when using sw_down/up
55        - improved logic for sw_lokey/hikey/up/down/last
56        - added more v1 aliases to parser
57        - reduced memory usage for sfz data
58        - RT-safeness: avoid malloc in audio thread
59        - fixed a bug that could cause voice stealing to fail
60        - optimized sample lookup
61        - improved support for exclusive groups (group, off_by and
62          off_mode)
63        - added support for controller triggered regions (on_locc/on_hicc)
64        - added support for loop_mode=one_shot
65        - fixed playback of 16 bit wav files on big endian CPUs
66        - added support for Ogg Vorbis sample files
67    
68      * SoundFont format engine:
69        - Initial implementation (not usable yet)
70        - RT-safeness: avoid malloc in audio thread
71        - fixed a bug that could cause voice stealing to fail
72

74        - AU bugfix: failed to destroy its audio/MIDI devices
75        - Listen to all interfaces on Mac OS X (INADDR_ANY)
76        - VST bugfix: If the host called resume() before and after
77          changing sample rate or block size, the number of channels was
78          incorrectly set to two. This caused silence in Cubase 5.
79    
80      * MIDI driver:
81        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82          the ALSA sequencer client name

156          of gigedit)
157        - added support for triggering notes by instrument editors (see above)
158        - be verbose on DLL load errors (on Linux)
159        - fixed di-harmonic triangle LFO implementation (this LFO implementation
160          is only used by very few systems, most pick the int math
161          implementation, which is usually faster)
162        - fixes for audio drivers with varying buffer sizes
163        - experimental support for running LinuxSampler as a DSSI, LV2 and
164          VST plugin
165        - notification events for stream/voice count statistics are now sent

170        - fixed CPU feature detection on x86_64 (maybe fixes #108)
171        - automatic stacktrace mechanism is now turned off by default and can
172          be switched on by command line option "--stacktrace" (the automatic
173          stacktrace mechanism seems to be broken on most systems at the moment)
174        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
175          a pointer to the launched InstrumentEditor object
176        - added optional 3rd party user data parameter for following
177          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
178          InstrumentEditor::Launch(),

197          jack_client_new
198        - added (experimental) CoreAudio driver
199        - applied old fixes to the ASIO driver that were included in the
200          previous binary release but accidentally never committed to CVS
201          (fixes #117)
202        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
203          win64)
204        - VST: added support for sample rate and buffer size changes
205        - VST: close editor (Fantasia) when the VST is removed

210          stereo
211        - added channel routing, fxsends and midi maps to the settings
212          stored in the plugin state

214          AudioChannel::CopyTo() methods using GCC vector exensions
215          (if available)
216        - ASIO fixes: avoid initializing the device twice, avoid throwing
217          exception when getting parameters from a disconnected device
218    
219      * MIDI driver:
220        - added JACK MIDI driver
221        - dispatch bank select as ordinary CC as well, the user might seriously
222          want to (mis)use it for some purpose ("fixed" in all current MIDI
223          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
224        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
225          CoreMidi or AU
226        - fixed mingw-w64 compilation error in MME driver

233        to the instruments database        to the instruments database
234        - added support for handling lost files in the instruments database
235        - Implemented option for adding instruments in separate directories
236          in the instruments database
237          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
238        - work-around for missing fnmatch function on Windows to make
239          instrument database compilable
240        - added instrument database support on Windows
241          works with both standalone mode and VST plugin.
242          the instruments DB file is located in
243          %USERPROFILE%\.linuxsampler\instruments.db which allows different
244          databases for each windows user
245          if no DB is present it automatically creates the .linuxsampler subdir
246          and then creates an empty DB
247        - fixed recursive import, which was broken on Windows
248    
249    * Gigasampler format engine:    * Gigasampler format engine:
250      - fixed a memory leak that could happen when a channel was deleted      - fixed a memory leak that could happen when a channel was deleted
251        while notes were playing        while notes were playing
252      - made it possible to load an instrument even if the audio thread      - made it possible to load an instrument even if the audio thread
253        isn't running        isn't running
254        - added partial support for the "Controller Triggered" MIDI rule,
255          enough for piano gigs with pedal noise samples
256        - minor fix: only mark FX sends as being modified if really the
257          respective FX send MIDI controller was used
258        - added support for GM global device volume SysEx message
259          (can be selected at compile time to either apply globally to the
260          whole sampler [default] or only to the sampler channels that are
261          connected to the respective MIDI input port the SysEx message arrived
262          on)
263        - bugfix: notes triggered at position 0 in the audio buffer were
264          sometimes wrongly killed in the same buffer, causing no sound to
265          be played
266        - added support for chromatic / drumkit mode Roland GS Sysex message
267          which is usally used to switch a part between chromatic sounds and
268          drumkit sounds (as opposed to their common default setting of MIDI
269          part 10 being a drumkit part and all other ones chromatic parts), in
270          LS however one can switch between the first 16 MIDI instrument maps
271          defined for the sampler
272        - made it possible to create multiple sample channels even if the
273          audio thread isn't running
274        - fixed crash when removing channel with active voices (#116)
275        - bugfix: on sample reference changes (instrument editor), only
276          un-cache the respective sample if it's really not used by any
277          sampler engine anymore
278        - re-cache samples in case they were changed by an instrument editor,
279          e.g. when a sample was added while playing (#82)
280        - fixed hanging notes which occured when note-off event had the exact
281          same time stamp as the voice's note-on event and occured both in the
282          same audio fragment cycle (fixes bug #112)
283        - added support for the "fine tune" and "pitch bend range"
284          instrument-level gig parameters
285        - fixed minor artifacts in pitch bend handling
286        - added support for GS Reset SysEx message
287        - allow gig files to use unlimited downward pitch shifting
288        - added a limit check for upward pitch shifting
289        - bugfix: sometimes, when playing a note twice fast, the second
290          note was silent
291        - fixed crash happening when a pitch bend event arrived at the
292          same time a new instrument was loading
293    
294      * LSCP server:
295        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
296          react on MIDI data arriving on certain sampler channels (so far only
297          Note-On and Note-Off events are sent via this LSCP event)
298        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
299          react on MIDI data arriving on certain MIDI input devices (so far only
300          Note-On and Note-Off events are sent via this LSCP event)
301        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
302          SET DB_INSTRUMENT FILE_PATH
303        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
304          frontends to send MIDI messages to specific sampler channel
305        - added two additional fields to GET FILE INSTRUMENT INFO command -
306          KEY_BINDINGS and KEYSWITCH_BINDINGS
307        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
308          was incorrect
309        - Optimized the retrieval of the MIDI instrument mappings
310        - added new LSCP command "SET VOICES" to globally alter the maximum
311          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
312          be triggered respectively
313        - added new LSCP command "SET STREAMS" to globally alter the maximum
314          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
315          which will be triggered respectively
316        - bugfix: retry if "select" returns EINTR (this fixes a crash when
317          a gigedit file dialog is opened)
318        - close all connections when LSCPServer is deleted
319        - hard close of all sockets on exit
320        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
321          driver
322    
323      * Bug fixes:
324        - fixed a crash which occurs when removing a sampler channel waiting
325          to start instrument loading after another channel
326        - fixed a crash which occurs when removing a sampler channel with
327          instrument loading in progress (bug #113)
328        - fixed termination caused by uncaught exception when adding MIDI
329          instrument with PERSISTENT load mode
330        - fixed possible iterator invalidations when resetting the sampler
331        - fixed memory leaks when issuing the following LSCP commands:
332          GET AUDIO_OUTPUT_DRIVER INFO
333          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
334          GET MIDI_INPUT_DRIVER INFO
335          GET MIDI_INPUT_DRIVER_PARAMETER INFO
336        - fixed possible compilation error when sqlite is not present
337        - fixed orphaned pointers when setting maximum voices limit (bug #118)
338        - fixed crash when changing the audio output device of a sampler
339          channel with loaded instrument and start playing notes
340        - fixed endless loop in Engine::SuspendAll() (bug #120)
341        - fixed a low-level atomic load function that was broken on 64-bit
342          PowerPC, which probably could cause crashes on that platform
343        - fixed a memory management error which could cause a crash when a
344          plugin was unloaded
345        - bugfix: two private structs had the same name, which could cause
346          problems if the linker chose the wrong constructor
347        - fixed low-level ConditionServer usage bug that caused lockups on
348          Windows
