# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * SFZ format engine:
4      - LV2 "state" extension support (patch by David Robillard)      - 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    
28      * packaging changes:
29        - removed unnecessary dependency to libuuid
30          (originated by libgig's usage of it)
31        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32          auto detect whether it (sh/c)ould output its messages in color.
33    
34      * Real-time instrument scripts:
35        - Implemented scheduler for delayed MIDI events and for suspended scripts.
36        - Built-in script function "wait()": implemented support for function's
37          "duration-us" argument, thus scripts using this function are now
38          correctly resumed after the requested amount of microseconds.
39        - Built-in script function "play_note()": implemented support for
40          function's "duration-us" argument, thus notes triggered with this
41          argument are now correctly released after the requested amount of
42          microseconds.
43        - Fix: script events were not cleared when engine channel was reset,
44          potentially causing undefined behavior.
45        - Fixed crash which happened when trying to reference an undeclared
46          variable.
47        - Built-in script function "play_note()": Added support for passing
48          special value -1 for "duration-us" argument, which will cause the
49          triggered note to be released once the original note was released.
50        - Instrument script classes now exported with the liblinuxsampler C++ API.
51        - Added new API method ScriptVM::syntaxHighlighting() which provides
52          a convenient syntax highlighting backend for external instrument
53          script editor applications.
54        - Added new C++ API class "ScriptVMFactory".
55        - Extended parser issues to provide not only first line and first
56          column, but also last line and last column of issue (thus marking
57          the precise span of the issue within the source code).
58        - Reload script automatically after being modified by an instrument
59          editor.
60        - NKSP language grammar correction: allow empty event handler bodies
61          like "on note end on".
62        - Implemented built-in script function "change_vol()".
63        - Implemented built-in script function "change_tune()".
64        - Implemented built-in script function "change_pan()".
65        - Implemented built-in script function "change_cutoff()".
66        - Implemented built-in script function "change_reso()".
67        - Implemented built-in script function "event_status()".
68        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70          "event_status()" function.
71        - NKSP language: Added support for bitwise operators ".or.", ".and."
72          and ".not.".
73        - NKSP language scanner: Fixed IDs matching to require at least one
74          character (i.e. when matching function names or variable names).
75        - NKSP language scanner: disabled unusued rules.
76        - Fixed behavior of play_note() and note_off() functions which must
77          be distinguished engine internally from "real" MIDI note on/off
78          events in order to avoid misbehaviors like hanging notes.
79        - Implemented built-in script variable "$KSP_TIMER".
80        - Implemented built-in script variable "$NKSP_REAL_TIMER".
81        - Implemented built-in script variable "$NKSP_PERF_TIMER".
82        - Implemented built-in script variable "$ENGINE_UPTIME".
83        - Implemented built-in script function "inc()".
84        - Implemented built-in script function "dec()".
85        - NKSP language fix: division expressions were evaluated too often.
86        - NKSP language fix: string concatenation operator was right
87          associative instead of left (to right).
88        - NKSP language correction: allow empty statements in entire language
89          (i.e. "if end if").
90        - Implemented built-in script function "stop_wait()".
91        - Implemented built-in script variable "$NI_CALLBACK_ID".
92        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94        - Added support for read-only built-in variables (respectively
95          handled by the script parser).
96        - Added built-in script constant "$NI_CB_TYPE_INIT".
97        - Added built-in script constant "$NI_CB_TYPE_NOTE".
98        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
100        - NKSP Language: Added support for user defined script functions.

172        "Foo.gig", "Foo.gx01", "Foo.gx02", ...        "Foo.gig", "Foo.gx01", "Foo.gx02", ...
173        - Added new C++ API method Sampler::GetGlobalMaxVoices().
174        - Added new C++ API method Sampler::GetGlobalMaxStreams().
175        - Added new C++ API method Sampler::SetGlobalMaxVoices().
176        - Added new C++ API method Sampler::SetGlobalMaxStreams().
177        - Various "const" and "restrict" optimizations.
178        - all engines: add pan CC value to instrument pan parameter before
179          applying panning, instead of using two separate pan functions in
180          series (#182)
181        - added a lock guard class for exception safe mutex handling and
182          used it everywhere appropriate
183        - Immediately apply scale tuning changes to active voices.
184        - Exposed scale tuning to C++ API (along to the already existing standard
185          SysEx way).
186        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
187          and broken for ppc64. (Seq_cst loads and stores are actually not
188          used in LS, so the bug wasn't noticable.)
189        - lsatomic.h: added ARMv7 support
190        - Added support for multiple MIDI input ports per sampler channel (and
191          added various new C++ methods for this new feature / design change, old
192          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
193          as deprecated but are still there and should provide full behavior
194          backward compatibility).
195        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
196          unsafe and caused compilation error with clang 2.x).
197        - Bugfix: only process the latest MIDI program change event.
198        - Introducing the LSCP shell, which provides convenient control of the
199          sampler from the command line by providing LSCP aware features.
200        - VirtualMidiDevice: Added support for program change.
201        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
202        - VirtualMidiDevice: Added support for pitch bend.
203        - Aftertouch: extended API to explicitly handle channel pressure and
204          polyphonic key pressure events (so far polyphonic pressure was not
205          supported at all, and channel pressure was rerouted as CC128 but not
206          used so far).
207        - Added initial support for real-time instrument scripts. The script VM
208          code is shared by all sampler engine implemementations, however only the
209          gig file format currently provides support for storing instrument scripts
210          (as LinuxSampler extension to the original GigaStudio 4 format).

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

445          informations like the EngineChannel for which the instrument editor was
446          spawned for. This allows the instrument editors to interact more actively
447          with the sampler.
