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

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

236        - filter performance fix (an unnecessary copy was made of the
237          filter parameters in each sub fragment)
238        - handle special case when pan parameter in gig file has max or
239          min value
240        - Exclusive Groups: don't ever stop voices of the same note,
241          doesn't sound naturally with a drumkit
242        - fixed EG1 modulation when attack or release is zero
243        - Fixed support for 'aftertouch' attenuation controller.
244        - Fixed crash that happened with velocity split sounds under certain
245          conditions (see also previous commit on libgig).
246        - fixed behaviour of filter LFO

623        - When creating MIDI instrument map entries with "PERSISTENT" type, the
624          instruments were uselessly precached with zero samples, however it still

626          instrument was completely reloaded again.
627        - fixed handling of rapid bank select and program change messages

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