# Line 1  Line 1 
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        - Added new C++ API method
33          VirtualMidiDevice::SendChannelPressureToSampler().
34        - windows, 32-bit: fixed potential crashes by making sure the stack in
35          sub threads is 16-byte aligned
36        - fixed numerous compiler warnings
37    
38      * packaging changes:
39        - removed unnecessary dependency to libuuid
40          (originated by libgig's usage of it)
41        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
42          auto detect whether it (sh/c)ould output its messages in color.
43    
44      * Real-time instrument scripts:
45        - Implemented scheduler for delayed MIDI events and for suspended scripts.
46        - Built-in script function "wait()": implemented support for function's
47          "duration-us" argument, thus scripts using this function are now
48          correctly resumed after the requested amount of microseconds.
49        - Built-in script function "play_note()": implemented support for
50          function's "duration-us" argument, thus notes triggered with this
51          argument are now correctly released after the requested amount of
52          microseconds.
53        - Fix: script events were not cleared when engine channel was reset,
54          potentially causing undefined behavior.
55        - Fixed crash which happened when trying to reference an undeclared
56          variable.
57        - Built-in script function "play_note()": Added support for passing
58          special value -1 for "duration-us" argument, which will cause the
59          triggered note to be released once the original note was released.
60        - Instrument script classes now exported with the liblinuxsampler C++ API.
61        - Added new API method ScriptVM::syntaxHighlighting() which provides
62          a convenient syntax highlighting backend for external instrument
63          script editor applications.
64        - Added new C++ API class "ScriptVMFactory".
65        - Extended parser issues to provide not only first line and first
66          column, but also last line and last column of issue (thus marking
67          the precise span of the issue within the source code).
68        - Reload script automatically after being modified by an instrument
69          editor.
70        - NKSP language grammar correction: allow empty event handler bodies
71          like "on note end on".
72        - Implemented built-in script function "change_vol()".
73        - Implemented built-in script function "change_tune()".
74        - Implemented built-in script function "change_pan()".
75        - Implemented built-in script function "change_cutoff()".
76        - Implemented built-in script function "change_reso()".
77        - Implemented built-in script function "event_status()".
78        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
79          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
80          "event_status()" function.
81        - NKSP language: Added support for bitwise operators ".or.", ".and."
82          and ".not.".
83        - NKSP language scanner: Fixed IDs matching to require at least one
84          character (i.e. when matching function names or variable names).
85        - NKSP language scanner: disabled unusued rules.
86        - Fixed behavior of play_note() and note_off() functions which must
87          be distinguished engine internally from "real" MIDI note on/off
88          events in order to avoid misbehaviors like hanging notes.
89        - Implemented built-in script variable "$KSP_TIMER".
90        - Implemented built-in script variable "$NKSP_REAL_TIMER".
91        - Implemented built-in script variable "$NKSP_PERF_TIMER".
92        - Implemented built-in script variable "$ENGINE_UPTIME".
93        - Implemented built-in script function "inc()".
94        - Implemented built-in script function "dec()".
95        - NKSP language fix: division expressions were evaluated too often.
96        - NKSP language fix: string concatenation operator was right
97          associative instead of left (to right).
98        - NKSP language correction: allow empty statements in entire language
99          (i.e. "if end if").
100        - Implemented built-in script function "stop_wait()".
101        - Implemented built-in script variable "$NI_CALLBACK_ID".
102        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
103        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
104        - Added support for read-only built-in variables (respectively
105          handled by the script parser).
106        - Added built-in script constant "$NI_CB_TYPE_INIT".
107        - Added built-in script constant "$NI_CB_TYPE_NOTE".
108        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
109        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
110        - NKSP Language: Added support for user defined script functions.
111        - Implemented built-in script function "change_attack()".
112        - Implemented built-in script function "change_decay()".
113        - Implemented built-in script function "change_release()".
114        - Fixed all change_*() built-in script functions to apply their
115          synthesis parameter changes immediately in case the respective note
116          was triggered at the same time, instead of scheduling the parameter
117          change, especially because it would cause some parameter types's
118          changes either to be ramped (i.e. change_vol()) or other types even
119          to have not effect at all (i.e. change_attack()).
120        - Implemented built-in script function "sh_left()".
121        - Implemented built-in script function "sh_right()".
122        - Implemented built-in script function "min()".
123        - Implemented built-in script function "max()".
124        - NKSP Fix: "init" event handler was not always executed when a script
125          was loaded.
126        - NKSP built-in wait() script function: abort script execution if
127          a negative or zero wait time was passed as argument (since this is
128          a common indication of a bug either of the script or even of the
129          engine, which could lead to RT instability or even worse).
130        - ScriptVM: Implemented automatic suspension of RT safety
131          threatening scripts.
132        - Provide more user friendly error messages on syntax errors.
133        - Fixed NKSP parser warning "Not a statement" when assigning an
134          initializer list to an array variable.
135    
136      * Instruments DB:
137        - Fixed memory access bug of general DB access code which lead to
138          undefined behavior.
139

215      - Various "const" and "restrict" optimizations.      - Various "const" and "restrict" optimizations.
216        - all engines: add pan CC value to instrument pan parameter before
217          applying panning, instead of using two separate pan functions in
218          series (#182)
219        - added a lock guard class for exception safe mutex handling and
220          used it everywhere appropriate
221        - Immediately apply scale tuning changes to active voices.
222        - Exposed scale tuning to C++ API (along to the already existing standard
223          SysEx way).
224        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
225          and broken for ppc64. (Seq_cst loads and stores are actually not
226          used in LS, so the bug wasn't noticable.)
227        - lsatomic.h: added ARMv7 support
228        - Added support for multiple MIDI input ports per sampler channel (and
229          added various new C++ methods for this new feature / design change, old
230          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
231          as deprecated but are still there and should provide full behavior
232          backward compatibility).
233        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
234          unsafe and caused compilation error with clang 2.x).
235        - Bugfix: only process the latest MIDI program change event.
236        - Introducing the LSCP shell, which provides convenient control of the
237          sampler from the command line by providing LSCP aware features.
238        - VirtualMidiDevice: Added support for program change.
239        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
240        - VirtualMidiDevice: Added support for pitch bend.
241        - Aftertouch: extended API to explicitly handle channel pressure and
242          polyphonic key pressure events (so far polyphonic pressure was not
243          supported at all, and channel pressure was rerouted as CC128 but not
244          used so far).
245        - Added initial support for real-time instrument scripts. The script VM
246          code is shared by all sampler engine implemementations, however only the
247          gig file format currently provides support for storing instrument scripts
248          (as LinuxSampler extension to the original GigaStudio 4 format).

431          after each "#include", only after the main file is parsed
432        - bugfix: line numbers in error messages were wrong after "#include"
433        - added support for float and 32 bit sample files

482        - Changed instrument editor plugin interface, providing additional
483          informations like the EngineChannel for which the instrument editor was
484          spawned for. This allows the instrument editors to interact more actively
485          with the sampler.

573        - Added support for moving cursor left/right with arrow keys.
574        - Added support for built-in LSCP reference documentation, which will
575          automatically show the relevant LSCP reference section on screen as soon
