2    
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
26    
27      * general changes:
28        - Refactoring: moved the independent code from
29          the Gigasampler format engine to base classes
30        - command line option '--profile' is currently disabled, since the
31          respective profiling code is currently broken
32        - Introduced support for optional environment variable
33          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34          where the sampler shall look for instrument editor plugins
35          (patch by Luis Garrido, slightly modified).
36        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39          note (in this implementation of the sampler its simply hard routed to
40          the 1st effect send of the sampler channel, no matter what the actual
41          effect type is)
42        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43          note (in this implementation of the sampler its simply hard routed to
44          the 2nd effect send of the sampler channel, no matter what the actual
45          effect type is)
46        - implemented support for internal LADSPA effects
47        - raised limit of program change queue from 100 to 512
48          (as suggested by Alex Stone)

53          EngineChannel::InstrumentFileName(int index)
54          allowing to retrieve the whole list of files used for the loaded
55          instrument on an engine channel (a.k.a. part). Some GigaStudio
56          instruments for example are splitted over several files like
57          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58        - Added new C++ API method Sampler::GetGlobalMaxVoices().
59        - Added new C++ API method Sampler::GetGlobalMaxStreams().
60        - Added new C++ API method Sampler::SetGlobalMaxVoices().
61        - Added new C++ API method Sampler::SetGlobalMaxStreams().
62        - Various "const" and "restrict" optimizations.

64          applying panning, instead of using two separate pan functions in
65          series (#182)
66    
67      * Gigasampler format engine:
68        - implemented the "round robin keyboard" dimension
69        - fixed round robin and random dimensions for cases when number of
70          dimension zones is not a power of two
71        - made round robin use a counter for each region instead of each
72          key
73        - bugfix: pitch LFO controller "internal+aftertouch" was broken
74        - bugfix: filter keyboard tracking was broken
75        - filter performance fix (an unnecessary copy was made of the
76          filter parameters in each sub fragment)
77        - handle special case when pan parameter in gig file has max or
78          min value
79    
80      * SFZ format engine:
81        - Initial implementation (not usable yet)
82        - added support for v2 multiple stage envelope generators
83        - added a fine-tuned v1 envelope generator instead of using the
84          one from the gig engine
85        - fixed memory leak and memory handling errors
86        - added support for trigger=first, trigger=legato and sw_previous
87        - allow non-numerical key values ("C#4" for example)

101        - improved logic for sw_lokey/hikey/up/down/last
102        - added more v1 aliases to parser
103        - reduced memory usage for sfz data
104        - RT-safeness: avoid malloc in audio thread

250          incorrectly set to two. This caused silence in Cubase 5.
251        - save engine type (gig, sfz or sf2) in plugin state
252        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
253          64 bit Windows
254        - AU: changed number of output channels from one stereo to 16
255          stereo

261          the plugin was loaded a second time (#174)
262        - plugin bugfix: instrument loading hang when the plugin was
263          loaded a second time (this time it's for Linux and Mac, previous
264          similar fix was for Windows)
265        - thread safety fixes for the instrument loading thread
266        - LV2: use the new lv2 package if present
267        - VST: try to open Fantasia automatically on Linux and Mac too (on
268          Linux, the Fantasia jar should be placed in <prefix>/share/java)
269        - VST: fixed crashes on Linux Ardour and EnergyXT
270        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
271          port and audio channel routing for DSSI plugins are now visible.
272        - LV2: use urid and atom extensions instead of deprecated uri-map
273          and event
274        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
275        - LV2: changed number of output channels to 16 stereo, just like
276          the VST and AU plugins
277        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
278        - LV2: made LV2 plugin buildable on Windows and Mac

284          the ALSA sequencer client name
285        - removed limit of maximum amount of MIDI ports per MIDI device, since
286          there is no reason for this limit
287        - MME: fixed memory handling bug found with cppcheck
288        - MME: removed compiler warning
289        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
290          which allows to retrieve the list of CoreMIDI clients / ports and to connect
291          to them a la JACK, via the usual sampler APIs
292        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
293          the driver will automatically connect to other CoreMIDI clients' ports
294          (e.g. external MIDI devices being attached to the Mac)
295        - added support for MIDI note on velocity filter
296        - CoreMIDI: fixed memory deallocation error
297        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

436          a pointer to the launched InstrumentEditor object
437        - added optional 3rd party user data parameter for following

500          instrument database compilable
501        - added instrument database support on Windows
502          works with both standalone mode and VST plugin.
503          the instruments DB file is located in
504          %USERPROFILE%\.linuxsampler\instruments.db which allows different
505          databases for each windows user

522          connected to the respective MIDI input port the SysEx message arrived
523          on)
524        - bugfix: notes triggered at position 0 in the audio buffer were
525          sometimes wrongly killed in the same buffer, causing no sound to
526          be played
527        - added support for chromatic / drumkit mode Roland GS Sysex message
528          which is usally used to switch a part between chromatic sounds and
529          drumkit sounds (as opposed to their common default setting of MIDI
530          part 10 being a drumkit part and all other ones chromatic parts), in
531          LS however one can switch between the first 16 MIDI instrument maps
532          defined for the sampler

537          un-cache the respective sample if it's really not used by any
538          sampler engine anymore
539        - re-cache samples in case they were changed by an instrument editor,
540          e.g. when a sample was added while playing (#82)
541        - fixed hanging notes which occured when note-off event had the exact
542          same time stamp as the voice's note-on event and occured both in the
543          same audio fragment cycle (fixes bug #112)
544        - added support for the "fine tune" and "pitch bend range"
545          instrument-level gig parameters
546        - fixed minor artifacts in pitch bend handling
547        - added support for GS Reset SysEx message
548        - allow gig files to use unlimited downward pitch shifting
549        - added a limit check for upward pitch shifting
550        - bugfix: sometimes, when playing a note twice fast, the second
551          note was silent
552        - fixed crash happening when a pitch bend event arrived at the
553          same time a new instrument was loading

559        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
560          react on MIDI data arriving on certain MIDI input devices (so far only
561          Note-On and Note-Off events are sent via this LSCP event)
562        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
563          SET DB_INSTRUMENT FILE_PATH
564        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
565          frontends to send MIDI messages to specific sampler channel
566        - added two additional fields to GET FILE INSTRUMENT INFO command -
567          KEY_BINDINGS and KEYSWITCH_BINDINGS
568        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
569          was incorrect
570        - Optimized the retrieval of the MIDI instrument mappings
571        - added new LSCP command "SET VOICES" to globally alter the maximum
572          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
573          be triggered respectively
574        - added new LSCP command "SET STREAMS" to globally alter the maximum
575          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
576          which will be triggered respectively
577        - bugfix: retry if "select" returns EINTR (this fixes a crash when
578          a gigedit file dialog is opened)
579        - close all connections when LSCPServer is deleted
580        - hard close of all sockets on exit
581        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
582          driver
583

604        - fixed a memory management error which could cause a crash when a
605          plugin was unloaded
606        - bugfix: two private structs had the same name, which could cause
607          problems if the linker chose the wrong constructor
608        - fixed low-level ConditionServer usage bug that caused lockups on
609          Windows
