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        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9    
10      * Gigasampler format engine:
11        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
12          cutoff settings.
13    
14      * general changes:
15        - fixed printf type errors (mostly in debug messages)
16        - use unique_ptr instead of auto_ptr when building with C++11
17        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
18          allowing to sort data efficiently in real-time safe manner.
19        - RTList class: added methods for moving/inserting elements to arbitrary
20          position within a list.
21        - RTList class: added method fromPtr() for creating an Iterator object from
22          a raw element pointer.
23        - Attempt to partly fix resetting engine channels vs. resetting engine, an
24          overall cleanup of the Reset*(), ConnectAudioDevice(),
25          DisconnectAudioDevice() API methods would still be desirable though,
26          because the current situation is still inconsistent and error prone.
27        - Active voices are now internally grouped to "Note" objects, instead of
28          being directly assigned to a keyboard key. This allows more fine graded
29          processing of voices, which is i.e. required for certain instrument
30          script features.
31        - Fix: Release trigger voices were not spawned on sustain pedal up
32          (CC #64) events.
33        - Fix: Release trigger voices can now also distinguish correctly between
34          note-off and sustain pedal up events.
35        - All engines: Increased ramp speed of volume smoother and pan smoother
36          (while slow rate of crossfade smoother is preserved) to allow quick
37          volume and pan changes by instrument scripts for instance.
38        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
39          properly and thus were ignored for certain uses.
40        - Added new C++ API method
41          VirtualMidiDevice::SendChannelPressureToSampler().
42        - windows, 32-bit: fixed potential crashes by making sure the stack in
43          sub threads is 16-byte aligned
44        - fixed numerous compiler warnings
45    
46      * packaging changes:
47        - removed unnecessary dependency to libuuid
48          (originated by libgig's usage of it)
49        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
50          auto detect whether it (sh/c)ould output its messages in color.
51    
52      * Real-time instrument scripts:
53        - Implemented scheduler for delayed MIDI events and for suspended scripts.
54        - Built-in script function "wait()": implemented support for function's
55          "duration-us" argument, thus scripts using this function are now
56          correctly resumed after the requested amount of microseconds.
57        - Built-in script function "play_note()": implemented support for
58          function's "duration-us" argument, thus notes triggered with this
59          argument are now correctly released after the requested amount of
60          microseconds.
61        - Fix: script events were not cleared when engine channel was reset,
62          potentially causing undefined behavior.
63        - Fixed crash which happened when trying to reference an undeclared
64          variable.
65        - Built-in script function "play_note()": Added support for passing
66          special value -1 for "duration-us" argument, which will cause the
67          triggered note to be released once the original note was released.
68        - Instrument script classes now exported with the liblinuxsampler C++ API.
69        - Added new API method ScriptVM::syntaxHighlighting() which provides
70          a convenient syntax highlighting backend for external instrument
71          script editor applications.
72        - Added new C++ API class "ScriptVMFactory".
73        - Extended parser issues to provide not only first line and first
74          column, but also last line and last column of issue (thus marking
75          the precise span of the issue within the source code).
76        - Reload script automatically after being modified by an instrument
77          editor.
78        - NKSP language grammar correction: allow empty event handler bodies
79          like "on note end on".
80        - Implemented built-in script function "change_vol()".
81        - Implemented built-in script function "change_tune()".
82        - Implemented built-in script function "change_pan()".
83        - Implemented built-in script function "change_cutoff()".
84        - Implemented built-in script function "change_reso()".
85        - Implemented built-in script function "event_status()".
86        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
87          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
88          "event_status()" function.
89        - NKSP language: Added support for bitwise operators ".or.", ".and."
90          and ".not.".
91        - NKSP language scanner: Fixed IDs matching to require at least one
92          character (i.e. when matching function names or variable names).
93        - NKSP language scanner: disabled unusued rules.
94        - Fixed behavior of play_note() and note_off() functions which must
95          be distinguished engine internally from "real" MIDI note on/off
96          events in order to avoid misbehaviors like hanging notes.
97        - Implemented built-in script variable "$KSP_TIMER".
98        - Implemented built-in script variable "$NKSP_REAL_TIMER".
99        - Implemented built-in script variable "$NKSP_PERF_TIMER".
100        - Implemented built-in script variable "$ENGINE_UPTIME".
101        - Implemented built-in script function "inc()".
102        - Implemented built-in script function "dec()".
103        - NKSP language fix: division expressions were evaluated too often.
104        - NKSP language fix: string concatenation operator was right
105          associative instead of left (to right).
106        - NKSP language correction: allow empty statements in entire language
107          (i.e. "if end if").
108        - Implemented built-in script function "stop_wait()".
109        - Implemented built-in script variable "$NI_CALLBACK_ID".
110        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
111        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
112        - Added support for read-only built-in variables (respectively
113          handled by the script parser).
114        - Added built-in script constant "$NI_CB_TYPE_INIT".
115        - Added built-in script constant "$NI_CB_TYPE_NOTE".
116        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
117        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
118        - NKSP Language: Added support for user defined script functions.
119        - Implemented built-in script function "change_attack()".
120        - Implemented built-in script function "change_decay()".
121        - Implemented built-in script function "change_release()".
122        - Fixed all change_*() built-in script functions to apply their
123          synthesis parameter changes immediately in case the respective note
124          was triggered at the same time, instead of scheduling the parameter
125          change, especially because it would cause some parameter types's
126          changes either to be ramped (i.e. change_vol()) or other types even
127          to have not effect at all (i.e. change_attack()).
128        - Implemented built-in script function "sh_left()".
129        - Implemented built-in script function "sh_right()".
130        - Implemented built-in script function "min()".
131        - Implemented built-in script function "max()".
132        - NKSP Fix: "init" event handler was not always executed when a script
133          was loaded.
134        - NKSP built-in wait() script function: abort script execution if
135          a negative or zero wait time was passed as argument (since this is
136          a common indication of a bug either of the script or even of the
137          engine, which could lead to RT instability or even worse).
138        - ScriptVM: Implemented automatic suspension of RT safety
139          threatening scripts.
140        - Provide more user friendly error messages on syntax errors.
141        - Fixed NKSP parser warning "Not a statement" when assigning an
142          initializer list to an array variable.
143        - Implemented built-in script array variable "%ALL_EVENTS".
144        - Implemented built-in script function "in_range()".
145    
146      * Instruments DB:
147        - Fixed memory access bug of general DB access code which lead to
148          undefined behavior.
149        - Cleanup of instruments DB file creation and opening code.
150        - The instrument DB path of linuxsampler's --create-instruments-db argument
151          is now optional, if it is missing, then a default location is used.
152        - Added support for scanning SFZ (.sfz) files.
153        - Added support for scanning Sound Font (.sf2) files.

242      - lsatomic.h: added ARMv7 support      - lsatomic.h: added ARMv7 support
243        - Added support for multiple MIDI input ports per sampler channel (and
244          added various new C++ methods for this new feature / design change, old
245          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
246          as deprecated but are still there and should provide full behavior
247          backward compatibility).
248        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
249          unsafe and caused compilation error with clang 2.x).
250        - Bugfix: only process the latest MIDI program change event.

254        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
255        - VirtualMidiDevice: Added support for pitch bend.
256        - Aftertouch: extended API to explicitly handle channel pressure and
257          polyphonic key pressure events (so far polyphonic pressure was not
258          supported at all, and channel pressure was rerouted as CC128 but not
259          used so far).
260        - Added initial support for real-time instrument scripts. The script VM
261          code is shared by all sampler engine implemementations, however only the
262          gig file format currently provides support for storing instrument scripts
263          (as LinuxSampler extension to the original GigaStudio 4 format).

588        - Added support for moving cursor left/right with arrow keys.
589        - Added support for built-in LSCP reference documentation, which will
590          automatically show the relevant LSCP reference section on screen as soon
591          as one specific LSCP command was detected while typing on the command

689          (fixes #208)
690        - Fixed bug in LSCP grammar definition which caused a statement like
691          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
692          practically irrelevant, however it caused problems with the new LSCP
693          shell's auto completion feature).
694        - Fixed MIDI program change messages being ignored if quickly executed
695          after each other (fixes #231).
