1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27        - All engines: Increased ramp speed of volume smoother and pan smoother
28          (while slow rate of crossfade smoother is preserved) to allow quick
29          volume and pan changes by instrument scripts for instance.
30        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31          properly and thus were ignored for certain uses.
32    
33      * packaging changes:
34        - removed unnecessary dependency to libuuid
35          (originated by libgig's usage of it)
36        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
37          auto detect whether it (sh/c)ould output its messages in color.
38    
39      * Real-time instrument scripts:
40        - Implemented scheduler for delayed MIDI events and for suspended scripts.
41        - Built-in script function "wait()": implemented support for function's
42          "duration-us" argument, thus scripts using this function are now
43          correctly resumed after the requested amount of microseconds.
44        - Built-in script function "play_note()": implemented support for
45          function's "duration-us" argument, thus notes triggered with this
46          argument are now correctly released after the requested amount of
47          microseconds.
48        - Fix: script events were not cleared when engine channel was reset,
49          potentially causing undefined behavior.
50        - Fixed crash which happened when trying to reference an undeclared
51          variable.
52        - Built-in script function "play_note()": Added support for passing
53          special value -1 for "duration-us" argument, which will cause the
54          triggered note to be released once the original note was released.
55        - Instrument script classes now exported with the liblinuxsampler C++ API.
56        - Added new API method ScriptVM::syntaxHighlighting() which provides
57          a convenient syntax highlighting backend for external instrument
58          script editor applications.
59        - Added new C++ API class "ScriptVMFactory".
60        - Extended parser issues to provide not only first line and first
61          column, but also last line and last column of issue (thus marking
62          the precise span of the issue within the source code).
63        - Reload script automatically after being modified by an instrument
64          editor.
65        - NKSP language grammar correction: allow empty event handler bodies
66          like "on note end on".
67        - Implemented built-in script function "change_vol()".
68        - Implemented built-in script function "change_tune()".
69        - Implemented built-in script function "change_pan()".
70        - Implemented built-in script function "change_cutoff()".
71        - Implemented built-in script function "change_reso()".
72        - Implemented built-in script function "event_status()".
73        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
74          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
75          "event_status()" function.
76        - NKSP language: Added support for bitwise operators ".or.", ".and."
77          and ".not.".
78        - NKSP language scanner: Fixed IDs matching to require at least one
79          character (i.e. when matching function names or variable names).
80        - NKSP language scanner: disabled unusued rules.
81        - Fixed behavior of play_note() and note_off() functions which must
82          be distinguished engine internally from "real" MIDI note on/off
83          events in order to avoid misbehaviors like hanging notes.
84        - Implemented built-in script variable "$KSP_TIMER".
85        - Implemented built-in script variable "$NKSP_REAL_TIMER".
86        - Implemented built-in script variable "$NKSP_PERF_TIMER".
87        - Implemented built-in script variable "$ENGINE_UPTIME".
88        - Implemented built-in script function "inc()".
89        - Implemented built-in script function "dec()".
90        - NKSP language fix: division expressions were evaluated too often.
91        - NKSP language fix: string concatenation operator was right
92          associative instead of left (to right).
93        - NKSP language correction: allow empty statements in entire language
94          (i.e. "if end if").
95        - Implemented built-in script function "stop_wait()".
96        - Implemented built-in script variable "$NI_CALLBACK_ID".
97        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
98        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
99        - Added support for read-only built-in variables (respectively
100          handled by the script parser).
101        - Added built-in script constant "$NI_CB_TYPE_INIT".
102        - Added built-in script constant "$NI_CB_TYPE_NOTE".
103        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
104        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
105        - NKSP Language: Added support for user defined script functions.
106        - Implemented built-in script function "change_attack()".
107        - Implemented built-in script function "change_decay()".
108        - Implemented built-in script function "change_release()".
109        - Fixed all change_*() built-in script functions to apply their
110          synthesis parameter changes immediately in case the respective note
111          was triggered at the same time, instead of scheduling the parameter
112          change, especially because it would cause some parameter types's
113          changes either to be ramped (i.e. change_vol()) or other types even
114          to have not effect at all (i.e. change_attack()).
115        - Implemented built-in script function "sh_left()".
116        - Implemented built-in script function "sh_right()".
117        - Implemented built-in script function "min()".
118        - Implemented built-in script function "max()".
119        - NKSP Fix: "init" event handler was not always executed when a script
120          was loaded.
121        - NKSP built-in wait() script function: abort script execution if
122          a negative or zero wait time was passed as argument (since this is
123          a common indication of a bug either of the script or even of the
124          engine, which could lead to RT instability or even worse).
125        - ScriptVM: Implemented automatic suspension of RT safety
126          threatening scripts.
127        - Provide more user friendly error messages on syntax errors.
128        - Fixed NKSP parser warning "Not a statement" when assigning an
129          initializer list to an array variable.

163          on the process's main thread
164        - fixed build error on newer MinGW
165        - support building with older jack versions
166        - support building with spaces in vst sdk path
167        - enabled automake 'subdir-objects' option and moved external
168          source references (vst, au, asio) from makefiles to cpp files,
169          in order to get rid of warnings from automake 1.14

210        - added a lock guard class for exception safe mutex handling and
211          used it everywhere appropriate
212        - Immediately apply scale tuning changes to active voices.
213        - Exposed scale tuning to C++ API (along to the already existing standard
214          SysEx way).
215        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
216          and broken for ppc64. (Seq_cst loads and stores are actually not
217          used in LS, so the bug wasn't noticable.)
218        - lsatomic.h: added ARMv7 support
219        - Added support for multiple MIDI input ports per sampler channel (and
220          added various new C++ methods for this new feature / design change, old
221          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
222          as deprecated but are still there and should provide full behavior
223          backward compatibility).
224        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
225          unsafe and caused compilation error with clang 2.x).
226        - Bugfix: only process the latest MIDI program change event.
227        - Introducing the LSCP shell, which provides convenient control of the
228          sampler from the command line by providing LSCP aware features.
229        - VirtualMidiDevice: Added support for program change.
230        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
231        - VirtualMidiDevice: Added support for pitch bend.
232        - Aftertouch: extended API to explicitly handle channel pressure and
233          polyphonic key pressure events (so far polyphonic pressure was not
234          supported at all, and channel pressure was rerouted as CC128 but not
235          used so far).
236        - Added initial support for real-time instrument scripts. The script VM
237          code is shared by all sampler engine implemementations, however only the
238          gig file format currently provides support for storing instrument scripts
239          (as LinuxSampler extension to the original GigaStudio 4 format).

562          be the case in other shells).
563        - Added support for moving cursor left/right with arrow keys.
564        - Added support for built-in LSCP reference documentation, which will
565          automatically show the relevant LSCP reference section on screen as soon
566          as one specific LSCP command was detected while typing on the command
567          line.

612        - Built-in script functions "ignore_event()", "note_off()" and
613          "gig_set_dim_zone()" now also accept an array of event IDs as argument
614          (i.e. return value of new script function "by_marks()").
615        - Pass/preserve polyphonic variable data from respective "note" event
616          handler to "release" event handler.

662        - ignore missing LADSPA paths without ignoring valid LADSPA paths
663          (fixes #208)
664        - Fixed bug in LSCP grammar definition which caused a statement like
665          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
666          practically irrelevant, however it caused problems with the new LSCP
667          shell's auto completion feature).
668        - Fixed MIDI program change messages being ignored if quickly executed
669          after each other (fixes #231).
