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

188        - support building with older jack versions
189        - support building with spaces in vst sdk path

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

497          informations like the EngineChannel for which the instrument editor was
498          spawned for. This allows the instrument editors to interact more actively
499          with the sampler.

583        - Added support for browsing command history with up / down keys.
584        - Show all possible next symbols immediately right to the current command
585          line while typing (no double tab required for this feature, as it would
586          be the case in other shells).
587        - Added support for moving cursor left/right with arrow keys.
588        - Added support for built-in LSCP reference documentation, which will

604        - Implemented built-in script function "play_note()" (only two of the
605          max. four function arguments are currently implemented yet though).
606        - Implemented built-in script int variable $EVENT_ID.
607        - Implemented built-in script function "ignore_event()"
608        - Implemented built-in script function "ignore_controller()" (may have one
609          or no argument).
