# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * General changes:    * 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    
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.
101        - Implemented built-in script function "change_attack()".
102        - Implemented built-in script function "change_decay()".
103        - Implemented built-in script function "change_release()".
104        - Fixed all change_*() built-in script functions to apply their
105          synthesis parameter changes immediately in case the respective note
106          was triggered at the same time, instead of scheduling the parameter
107          change, especially because it would cause some parameter types's
108          changes either to be ramped (i.e. change_vol()) or other types even
109          to have not effect at all (i.e. change_attack()).
110

112    
113      * packaging changes:

159        (patch by Luis Garrido, slightly modified).        (patch by Luis Garrido, slightly modified).
160        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
161        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
162        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
163          note (in this implementation of the sampler its simply hard routed to
164          the 1st effect send of the sampler channel, no matter what the actual
165          effect type is)
166        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
167          note (in this implementation of the sampler its simply hard routed to
168          the 2nd effect send of the sampler channel, no matter what the actual
169          effect type is)
170        - implemented support for internal LADSPA effects
171        - raised limit of program change queue from 100 to 512
172          (as suggested by Alex Stone)
173        - implemented sine LFO, pulse LFO and saw LFO
174        - experimental support for per voice equalization
175        - added command line option --exec-after-init
176        - Introduced new C++ API method:
177          EngineChannel::InstrumentFileName(int index)
178          allowing to retrieve the whole list of files used for the loaded
179          instrument on an engine channel (a.k.a. part). Some GigaStudio
180          instruments for example are splitted over several files like
181          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
182        - Added new C++ API method Sampler::GetGlobalMaxVoices().
183        - Added new C++ API method Sampler::GetGlobalMaxStreams().
184        - Added new C++ API method Sampler::SetGlobalMaxVoices().
185        - Added new C++ API method Sampler::SetGlobalMaxStreams().
186        - Various "const" and "restrict" optimizations.
187        - all engines: add pan CC value to instrument pan parameter before
188          applying panning, instead of using two separate pan functions in
189          series (#182)
190        - added a lock guard class for exception safe mutex handling and
191          used it everywhere appropriate
192        - Immediately apply scale tuning changes to active voices.
193        - Exposed scale tuning to C++ API (along to the already existing standard
194          SysEx way).
195        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
196          and broken for ppc64. (Seq_cst loads and stores are actually not
197          used in LS, so the bug wasn't noticable.)
198        - lsatomic.h: added ARMv7 support
199        - Added support for multiple MIDI input ports per sampler channel (and
200          added various new C++ methods for this new feature / design change, old
201          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
202          as deprecated but are still there and should provide full behavior
203          backward compatibility).
204        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
205          unsafe and caused compilation error with clang 2.x).
206        - Bugfix: only process the latest MIDI program change event.
207        - Introducing the LSCP shell, which provides convenient control of the
208          sampler from the command line by providing LSCP aware features.
209        - VirtualMidiDevice: Added support for program change.
210        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
211        - VirtualMidiDevice: Added support for pitch bend.
212        - Aftertouch: extended API to explicitly handle channel pressure and
213          polyphonic key pressure events (so far polyphonic pressure was not
214          supported at all, and channel pressure was rerouted as CC128 but not
215          used so far).
216        - Added initial support for real-time instrument scripts. The script VM
217          code is shared by all sampler engine implemementations, however only the
218          gig file format currently provides support for storing instrument scripts
219          (as LinuxSampler extension to the original GigaStudio 4 format).

615          after MIDI/audio device creation failure
616        - When creating MIDI instrument map entries with "PERSISTENT" type, the
617          instruments were uselessly precached with zero samples, however it still
618          took the full preloading time and on 1st program change the respective
619          instrument was completely reloaded again.
620        - fixed handling of rapid bank select and program change messages
621          sent to the same sampler channel (patch from the Open Octave

642        - ignore missing LADSPA paths without ignoring valid LADSPA paths
643          (fixes #208)
644        - Fixed bug in LSCP grammar definition which caused a statement like
645          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
646          practically irrelevant, however it caused problems with the new LSCP
647          shell's auto completion feature).
648        - Fixed MIDI program change messages being ignored if quickly executed
649          after each other (fixes #231).
