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

205        (patch by Luis Garrido, slightly modified).        (patch by Luis Garrido, slightly modified).
206        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
207        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
208        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
209          note (in this implementation of the sampler its simply hard routed to
210          the 1st effect send of the sampler channel, no matter what the actual
211          effect type is)
212        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
213          note (in this implementation of the sampler its simply hard routed to
214          the 2nd effect send of the sampler channel, no matter what the actual
215          effect type is)
216        - implemented support for internal LADSPA effects
217        - raised limit of program change queue from 100 to 512
218          (as suggested by Alex Stone)
219        - implemented sine LFO, pulse LFO and saw LFO
220        - experimental support for per voice equalization
221        - added command line option --exec-after-init
222        - Introduced new C++ API method:
223          EngineChannel::InstrumentFileName(int index)
224          allowing to retrieve the whole list of files used for the loaded
225          instrument on an engine channel (a.k.a. part). Some GigaStudio
226          instruments for example are splitted over several files like
227          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
228        - Added new C++ API method Sampler::GetGlobalMaxVoices().
229        - Added new C++ API method Sampler::GetGlobalMaxStreams().
230        - Added new C++ API method Sampler::SetGlobalMaxVoices().
231        - Added new C++ API method Sampler::SetGlobalMaxStreams().
232        - Various "const" and "restrict" optimizations.
233        - all engines: add pan CC value to instrument pan parameter before
234          applying panning, instead of using two separate pan functions in
235          series (#182)
236        - added a lock guard class for exception safe mutex handling and
237          used it everywhere appropriate
238        - Immediately apply scale tuning changes to active voices.
239        - Exposed scale tuning to C++ API (along to the already existing standard
240          SysEx way).
241        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
242          and broken for ppc64. (Seq_cst loads and stores are actually not
243          used in LS, so the bug wasn't noticable.)
244        - lsatomic.h: added ARMv7 support
245        - Added support for multiple MIDI input ports per sampler channel (and
246          added various new C++ methods for this new feature / design change, old
247          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
248          as deprecated but are still there and should provide full behavior
249          backward compatibility).
250        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
251          unsafe and caused compilation error with clang 2.x).
252        - Bugfix: only process the latest MIDI program change event.
253        - Introducing the LSCP shell, which provides convenient control of the
254          sampler from the command line by providing LSCP aware features.
255        - VirtualMidiDevice: Added support for program change.
256        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
257        - VirtualMidiDevice: Added support for pitch bend.
258        - Aftertouch: extended API to explicitly handle channel pressure and
259          polyphonic key pressure events (so far polyphonic pressure was not
260          supported at all, and channel pressure was rerouted as CC128 but not
261          used so far).
262        - Added initial support for real-time instrument scripts. The script VM
263          code is shared by all sampler engine implemementations, however only the
264          gig file format currently provides support for storing instrument scripts
265          (as LinuxSampler extension to the original GigaStudio 4 format).

273        - bugfix: pitch LFO controller "internal+aftertouch" was broken
274        - bugfix: filter keyboard tracking was broken
275        - filter performance fix (an unnecessary copy was made of the
276          filter parameters in each sub fragment)
277        - handle special case when pan parameter in gig file has max or
278          min value
279        - Exclusive Groups: don't ever stop voices of the same note,
280          doesn't sound naturally with a drumkit
281        - fixed EG1 modulation when attack or release is zero
282        - Fixed support for 'aftertouch' attenuation controller.
283        - Fixed crash that happened with velocity split sounds under certain
284          conditions (see also previous commit on libgig).
285        - fixed behaviour of filter LFO

666          took the full preloading time and on 1st program change the respective
667          instrument was completely reloaded again.
668        - fixed handling of rapid bank select and program change messages

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