* added LSCP event "DEVICE_MIDI"

1 capela 103 liblscp - LinuxSampler Control Protocol API
2     -------------------------------------------
3    
4     ChangeLog
5    
6 schoenebeck 1692 CVS HEAD Bugfix: _lscp_client_evt_proc() dropped LSCP events.
7    
8     Bugfix in lscp_client_subscribe(): only the first
9 schoenebeck 1690 lscp_client_subscribe() call succeeded (per client),
10     all subsequent ones failed.
11    
12     Added support for new (un)subscribable events:
13 schoenebeck 1689 LSCP_EVENT_CHANNEL_MIDI
14 schoenebeck 1697 LSCP_EVENT_DEVICE_MIDI
15 schoenebeck 1689 Caution: the bitflag approach for the event variable
16     is now abondoned, since otherwise we would soon hit the
17     limit of the bit range. The bitflag approach will
18     remain for events older at this point (that is all
19     events which occupy the lower 16 bits), but this new
20     and all following events will simply be enumared along
21     the upper 16 bits.
22    
23     Added new client interface function, for renaming
24 schoenebeck 1665 effect send entities:
25     lscp_set_fxsend_name();
26    
27 capela 1412 0.5.5 2007-10-12 Changed client interface function, for editing
28     instrument, from:
29     lscp_edit_instrument();
30     to:
31     lscp_edit_channel_instrument();
32    
33 capela 1368 0.5.4 2007-10-02 Added new client interface function, for editing
34 schoenebeck 1365 instrument:
35     lscp_edit_instrument();
36    
37     Fixed some minor bugs in:
38     lscp_set_fxsend_midi_controller();
39     lscp_set_fxsend_level();
40    
41 capela 1031 0.5.3 2007-01-15 Added new client interface functions, for sampler
42     channel effect sends control:
43     lscp_set_fxsend_midi_controller();
44     lscp_set_fxsend_level();
45    
46     Added new field member to lscp_fxsend_info_t (level).
47    
48 capela 1019 0.5.2 2007-01-11 Added new client interface functions, for sampler
49     channel effect sends control:
50     lscp_create_fxsend();
51     lscp_destroy_fxsend();
52     lscp_get_fxsends();
53     lscp_list_fxsends();
54     lscp_get_fxsend_info();
55     lscp_set_fxsend_audio_channel();
56 capela 1369 and for global volume:
57 capela 1019 lscp_get_volume();
58     lscp_set_volume();
59    
60 capela 1031 Audio routing representation changed to integer array.
61 capela 1020
62 capela 997 0.5.1 2006-12-22 Added support for new (un)subscribable events:
63 capela 994 LSCP_EVENT_AUDIO_OUTPUT_DEVICE_COUNT,
64     LSCP_EVENT_AUDIO_OUTPUT_DEVICE_INFO,
65     LSCP_EVENT_MIDI_INPUT_DEVICE_COUNT,
66     LSCP_EVENT_MIDI_INPUT_DEVICE_INFO,
67     LSCP_EVENT_MIDI_INSTRUMENT_MAP_COUNT,
68     LSCP_EVENT_MIDI_INSTRUMENT_MAP_INFO,
69     LSCP_EVENT_MIDI_INSTRUMENT_COUNT,
70     LSCP_EVENT_MIDI_INSTRUMENT_INFO.
71    
72     Updated examples.
73 capela 983
74 capela 975 0.5.0 2006-12-17 MIDI instrument mapping, second round, according to
75     LSCP 1.2 draft document as of December 15, 2006.
76    
77     New client interface functions:
78     lscp_set_channel_midi_map();
79     lscp_add_midi_instrument_map();
80     lscp_remove_midi_instrument_map();
81     lscp_get_midi_instrument_maps();
82     lscp_list_midi_instrument_maps();
83     lscp_get_midi_instrument_map_name();
84     lscp_set_midi_instrument_map_name();
85    
86    
87 capela 965 0.4.2 2006-12-04 MIDI instrument mapping fixed, previously missing
88 capela 963 the regular ON_DEMAND load mode.
89    
90     Server error reporting is now effective; all server
91     numerical error and warning codes are added to 100,
92     thus giving a proper non-zero lscp_client_get_errno()
93     return value.
94    
95 capela 948 0.4.1 2006-11-28 Fixed the flush timeout operation to be issued only
96     once, avoiding recurrent client failure after receive
97     timeout.
98    
99     Support for very long command result sets have been
100     introduced, with the downside of strictly obeying
101     the LSCP draft.
102    
103     list_midi_instruments() is now being implemented.
104    
105     LGPL text is now back in COPYING.
106    
107 capela 946 0.4.0 2006-11-27 As of the LSCP 1.2 working draft document, added
108     some missing client interface functions:
109     lscp_get_total_voice_count();
110     lscp_get_total_voice_count_max();
111     and for the new MIDI instrumenbt mapping features:
112     lscp_map_midi_instrument();
113     lscp_unmap_midi_instrument();
114     lscp_get_midi_instruments();
115     lscp_get_midi_instrument_info();
116     lscp_clear_midi_instruments();
117    
118    
119 capela 921 0.3.4 2006-09-24 GPL address update.
120    
121 capela 869 0.3.3 2006-06-01 Fixed some compilation warnings due to suspicious type
122     casting and unsused header macros.
123    
124     Changed deprecated copyright attribute to license
125     and added ldconfig to post-(un)install steps
126     to liblscp.spec (RPM).
127    
128 capela 764 0.3.2 2005-08-29 Fixed missing initialization bug on lscp_channel_info_t
129 capela 749 new struct fields (mute/solo).
130    
131     Include debian files into distribution.
132    
133 capela 754 Renamed configure.in to newer configure.ac.
134    
135 capela 735 0.3.1 2005-08-16 [bug #21] Fixed automake support for separate build
136 capela 712 directory.
137 capela 749
138 capela 735 Added support to sampler channel MUTE/SOLO states:
139     lscp_set_channel_mute();
140     lscp_set_channel_solo();
141     with corresponding new lscp_channel_info_t fields.
142 capela 712
143 capela 626 0.3.0 2005-06-10 [bug #11] Timeout flush idiosyncrasy is now a feature;
144 capela 623 this just tries to flush the receive buffer whenever
145     any previous transaction has failed due to a timeout.
146    
147 capela 626 Fixed an off-by-one timeout quirk, that has been a real
148     showstopper on Mac OS X at least, which is incidental
149     to qsampler's default timeout setting of 1000 msecs,
150     giving up systematically on select() due to "Invalid
151     argument" (EINVAL).
152    
153 capela 946
154 capela 562 0.2.8 2005-05-22 More LSCP command syntax changes, particularly on the
155     event subscription ones: the LSCP_EVENT_CHANNELS event
156     definition were renamed to LSCP_EVENT_CHANNEL_COUNT,
157 capela 564 as to be more meaningful. Added support for the newest
158     LSCP command: GET SERVER INFO; lscp_get_server_info().
159 capela 562
160 capela 523 0.2.8 2005-05-08 [bug #9] Fixed for a LSCP command syntax convention
161     consistency, regarding the enumeration of available
162     sampler engines, Audio and MIDI drivers; this has
163     affected the signature of the following functions:
164     lscp_get_available_engines();
165     lscp_get_available_audio_drivers();
166     lscp_get_available_midi_drivers();
167     which are now returning an integer count of engines
168     and drivers, respectively, while the following
169     functions are now being introduced:
170     lscp_list_available_engines();
171     lscp_list_available_audio_drivers();
172     lscp_list_available_midi_drivers();
173     taking on the previous functionality, returning
174     a comma separated list of names.
175    
176 capela 445 0.2.7 2005-03-10 Mini bitsy regression; a severe crash (segfault)
177 capela 435 was fixed on the device configuration functions:
178     lscp_set_audio_device_param();
179     lscp_set_midi_device_param();
180     lscp_set_audio_channel_param();
181     lscp_set_midi_port_param();
182 capela 419
183 capela 415 0.2.6 2005-03-01 Fixed nasty off-by-one bug on internal helpers.
184    
185 capela 380 0.2.5 2005-02-14 Added support for the new INSTRUMENT_NAME field
186 capela 378 of GET CHANNEL INFO command.
187    
188 capela 278 0.2.4 2004-10-11 Fixed lscp_set_channel_midi_channel() again, MIDI
189     channels should be given in the range 0-15, and omni
190     mode with the LSCP_MIDI_CHANNEL_ALL symbol (16).
191 capela 415
192 capela 279 Fixed lscp_get_channel_info() to parse MIDI omni
193     (ALL) channels mode.
194 capela 278
195 capela 257 0.2.3 2004-09-28 Fixed lscp_set_channel_midi_channel() where MIDI
196     channels should be given in the range 1-16, and
197     omni mode with the new LSCP_MIDI_CHANNEL_ALL
198     symbol (0).
199 capela 415
200 capela 253 Rearrangement on main command requester executive.
201    
202 capela 213 0.2.2 2004-07-29 In sync with LSCP document draf (v.12).
203    
204     New functions added: lscp_client_get_events() and
205     lscp_reset_sampler().
206    
207     Added support for generating Debian packages;
208 schoenebeck 199 renamed pkg-config lib name 'liblscp' -> 'lscp' as
209     it's common practice to omit the 'lib' prefix.
210    
211 capela 194 0.2.1 2004-07-09 Potential cripling defects habve been fixed.
212 capela 187
213 capela 178 0.2.0 2004-07-06 New LSCP extension draft (v.11) initial support.
214 capela 103 (still a work in progress...)
215    
216 capela 946
217 capela 103 0.1.9 2004-05-18 More fixes for MSVC++ example build.
218    
219     0.1.8 2004-05-17 Fix for MSVC++ example build; snprintf replaced by
220     buffer overflow friendlier sprintf.
221    
222     0.1.7 2004-05-10 Missing version.h now included on install; WIN32 is
223     only now conditionally defined.
224    
225     0.1.6 2004-05-04 WIN32 build support; LPGL disclaimer consistency;
226     versioning functions introduced.
227    
228     0.1.5 2004-04-26 Server stuff moved into examples.
229    
230     0.1.4 2004-04-24 Initial auto/libtool preparation.
