* Preparations for new release (2.1.1).

1 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
2    
3     This is a maintenance release with various fixes. There are only two
4     minor new features in this release:
5    
6     The Giga format engine adds a format extension which allows sound
7     designers to define whether release trigger samples shall be played when
8     the sustain pedal is released. In the previous release this was actually
9     the default behaviour by the sampler, but meanwhile there was a consensus
10     on the mailing list that release samples being triggered by sustain pedal
11     is not the common, expected behaviour. So this is no longer the default
12     behaviour, but you can still opt in to this old behaviour by using this
13     new format extension option (i.e. by using latest release version of
14     libgig and gigedit and enabling the respective checkbox for your
15     gig instrument). If you don't enable this option then release samples are
16     now only triggered by note-off events.
17    
18     The sfz engine adds support for the commonly used built-in sample
19     '*silence' of the sfz format. It does what you think it does; it
20     instructs the sampler to play no sound at all. This is commonly used
21     in sfz files for instance for the lowest velocity switch to not play any
22     sample. With the previous release trying to load sfz files which used this
23     built-in sample caused a file loading error. There are various other
24     commonly used built-in samples in sfz files which you can denote by the
25     leading star character in the sample name, however the '*silence' one is
26     currently the only supported built-in sample by our sfz engine yet. Trying
27     to load sfz files which are using other built-in samples does not prevent
28     your instrument from being loaded by the sampler, however you will get a
29     warning message on the console that the built-in sample is not supported
30     yet and the sampler will simply play silence for that non supported
31     built-in sample.
32    
33 schoenebeck 3372 Version 2.1.0 (25 November 2017)
34    
35     This release adds a large amount of extensions and improvements for the
36     real-time instrument scripting support of LinuxSampler (NKSP).
37     For example 48 new built-in NKSP functions and 21 new built-in NKSP
38     variables have been added. Also the NKSP language itself was extended.
39     Most notably the script engine now has an execution scheduler which is
40     the basis for many of the timing relevant new NKSP features in this
41     release, like programmatically suspending and resuming scripts for an
42     exact amount of time or triggering or killing notes at very precise
43     times. Bitwise operators have been added to NKSP, as well as support for
44     read only built-in variables, "synchronized" code blocks
45     ("synchronized .. end synchronized"), user declared functions and user
46     declared const array variables have been added to the NKSP language,
47     and automatic suspension of RT threatening scripts by the RT script engine
48     has been implemented. Also syntax error messages with NKSP scripts have
49     been improved to output more clear and user friendly error messages, as
50     well as NKSP editor API has been improved which brings handy new features
51     to gigedit's NKSP script editor like automatically graying out code blocks
52     which are disabled by NKSP preprocessor statements.
53    
54     The SFZ engine now supports <global>, <master>, #define and set_ccN
55     statements. And finally the SFZ engine now supports NKSP real-time
56     instrument scripts as well by adding a new "script" opcode.
57    
58     Also the Instruments Database feature has received important maintenance
59     fixes. Before this release the instrument DB feature was barely usable
60     for quite some time. Fundamental instruments DB issues have been fixed in
61     this release to finally consider this feature stable again.
62    
63     And finally this release provides a huge amount of general bug fixes.
64    
65 schoenebeck 2788 Version 2.0.0 (15 July 2015)
66    
67     The sampler's code base has seen substantial changes in the last six years,
68     since the last release of LinuxSampler. The sampler engine code base has
69     been unified to a set of abstract base classes which cleared the way for
70     two new sampler engines: The SFZ2 format engine (.sfz) and the SoundFont 2
71     engine (.sf2). So LinuxSampler is not limited to the GigaStudio/Gigasampler
72     format (.gig) anymore. Another major new feature is support for real-time
73     instrument scripts, which may be bundled with sound files to extend the
74     sampler with custom behavior for individual sounds. You may know such scripts
75     from commercial software samplers. Find out more about instrument scripts
76     on http://doc.linuxsampler.org/Instrument_Scripts/. At the moment this
77     scripting feature is yet limited to the Giga format engine. Also noteworthy
78     is the new command line application "lscp", which is a text based shell for
79     controlling the sampler from the command line, providing colored output,
80     type completion, help text while typing LSCP commands and other convenient
81     features. You may now also load external effects directly into the sampler
82     (only LADSPA plugins yet). The LSCP network protocol (v1.7) has been extended
83     to manage such effects respectively. Also new with latest LSCP version is the
84     ability to trigger MIDI CCs by LSCP commands. You may have heard that the
85     GigaStudio software has seen its last version with GigaStudio 4. Tascam
86     officially discontinued this product, its intellectual property has been sold
87     several times among companies and there is currently no way to buy a new copy
88     of GigaStudio anymore. However the GigaStudio format is still under active
89     development with LinuxSampler. We not only added support for the latest
90     features introduced with GigaStudio 4: iMIDI rules for example which allow to
91     trigger notes by MIDI CC and allow i.e. defining a set of legato samples; for
92     the first time ever we also added our own extensions to the Giga format: one
93     of it is the previously mentioned new instrument scripting feature and a more
94     minor extension is support for various other MIDI CCs which were never
95     supported by GigaStudio before. The sampler's host plugins have also seen
96     some enhancements: the LV2 plugin now stores and restores the sampler's
97     overall state with your DAW application's song, the LV2 and AudioUnit
98     plugin's outputs were increased from 2 audio channels to 16 upon request by
99     some users and the VST plugin now uses the sampler's MIDI instrument mapping
100     system to show a list of available sounds to allow the user to switch among
101     them. And last but not least the VST plugin may also be used on Mac now.
102    
103 persson 1957 Version 1.0.0 (31 July 2009)
104 schoenebeck 1956
105     This is the first release which allows the sampler to be used as audio
106     host plugin, namely supporting the standards VST, AU, DSSI and LV2. The
107     sampler's limits for max. voices & disk streams can now be altered at
108     runtime by frontends, no need to recompile the sampler anymore. The Mac
109     version now also supports CoreAudio as audio driver. The Windows version
110     finally supports the sampler's instruments DB feature as well, however
111     expect it still to be unstable at this point. Along to the already
112     existing JACK audio driver, Jack MIDI support has been added in this
113     release. The sampler allows frontends now basic MIDI control, that is to
114     monitor incoming MIDI data on MIDI input devices and sampler channels and
115     to send note-on and note-off MIDI events to sampler channels, which
116     allows frontends to provide a virtual MIDI keyboard to the user. Besides
117     these major changes there were countless bugfixes and optimizations.
118    
119 schoenebeck 1560 Version 0.5.1 (6 December 2007)
120    
121     This is the first release for the Windows platform, providing a MME MIDI
122     input driver and ASIO audio output driver. Note that the instruments DB
123     feature is not yet available for Windows systems, since the respective
124     code base has yet to be ported. Needless to say that there still might be
125     plenty of issues on MS systems. Beside that support for Windows, this is
126     merely a bugfix release (i.e. fixing one serious crash) with only minor
127     new features.
128    
129 schoenebeck 1424 Version 0.5.0 (15 October 2007)
130    
131     This release comes with a bunch of important new features. We implemented
132     a very powerful and easy MIDI program change mapping, which not only
133     allows you to define which instrument to load on which MIDI program
134     change number (and bank select number), it also allows further parameters
135     like whether the instrument shall be pre-cached or loaded only when needed
136     (and likewise freed when not needed). You can create arbitrary amount of
137     effect sends for each sampler channel, each having an arbitrary MIDI
138     controller for controlling the effect send level in realtime and can
139     flexible be routed to some of the sampler's audio output channel, i.e.
140     to a dedicated one for a certain effect type. The new instruments
141     database allows you to keep track even of largest instrument library
142     collections. You can order them in categories and search by various
143     criteria. The sampler now allows third party applications to offer so
144     called 'instrument editor plugins' which the sampler can use to spawn
145     an appropriate instrument editor application for a selected instrument
146     and for allowing to edit instruments with such an external editor
147     application on-the-fly, that is all modifications made with the editor
148     will immediately be audible with the sampler. No need to reload instrument
149     files anymore. Checkout our brand new instrument editor application called
150     'gigedit' which you can use for this feature. Loading huge instruments may
151     take a long time, that's why the sampler now allows to play an instrument
152     while loading. That way you can i.e. play and hold notes on the keyboard
153     while loading a new instrument on the same sampler channel at the same
154     time. Beside these new features, you can find the common huge list of bug
155     fixes and quality improvements.
156    
157 schoenebeck 937 Version 0.4.0 (24 November 2006)
158    
159     Finally a new release after a long development cycle. The sampler now has
160     a completely revised synthesis core. Note that due to this, most of the
161     assembly code became incompatible and is thus deactivated at compile
162     time. So don't bother trying to activate the assembly option, it won't
163     compile! That's not an issue though, because even without assembly, the
164     new synthesis core is faster than the old one with assembly. The
165     Gigasampler engine now has real support for 24 bit samples, that is they
166     won't be truncated anymore, and finally supports all filter types of the
167     Gigasampler format. A lot of effort has been put into making all filters
168     under all parameters being as accurate as possible, compared to the
169     original Gigasampler ones. Analogue to hardware mixers, sampler channels
170     can now be muted and solo-ed and there is support for GM portamento and
171     GM mono mode (single note per channel) as well as support for sostenuto
172     pedal. Beside LSCP, third-party applications can now also link against
173     liblinuxsampler directly (using the sampler's C++ API). Beside these,
174     there have been of course a huge bunch of fixes and quality improvements.
175    
176 schoenebeck 692 Version 0.3.3 (15 July 2005)
177    
178     Another bug fix release. It solves one usability issue regarding small
179     fragments / high sampling rates of audio drivers, fixes some compile time
180     errors with GCC 4.0 and fixes a minor efficiency bug.
181    
182 schoenebeck 677 Version 0.3.2 (24 June 2005)
183    
184     This is more or less just a bug fix release. Beside a bunch of little
185     fixes it solves a serious crash in conjunction with voice stealing and
186     slightly improves Gigasampler format playback accuracy.
