annotate CHANGELOG @ 1480:f1e1745acc3b 3.0-integration

Make the colour 3d plot renderer able to support more than one level of peak cache; introduce a second "peak" cache for the spectrogram layer that actually has a 1-1 column relationship with the underlying FFT model, and use it in addition to the existing peak cache if memory is plentiful. Makes spectrograms appear much faster in many common situations.

Chris@1447 1
Chris@1447 2 Changes in Sonic Visualiser 3.0 since the previous release 2.5:
Chris@1447 3
Chris@1447 4 - Add ability to record audio, and ability to change audio device for
Chris@1447 5 playback or recording in the preferences
Chris@1447 6
Chris@1447 7 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1447 8 displays, spanning layer data rendering and UI controls and
Chris@1447 9 icons. This makes the biggest difference when using a retina Mac,
Chris@1447 10 on which previous versions did not render layer data at retina
Chris@1447 11 resolution, but it also improves scaling and rendering of UI
Chris@1447 12 elements on Hi-DPI displays on Windows and Linux
Chris@1447 13
Chris@1447 14 - Add ability to open, display, and analyse very long audio files (of
Chris@1447 15 more than 2^32 sample frames)
Chris@1447 16
Chris@1451 17 - Add ability to export scalable (SVG) image files
Chris@1451 18
Chris@1447 19 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 20 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 21 respect the behaviour should be unchanged
Chris@1447 22
Chris@1447 23 - Scan plugins on startup in a separate process, and report on any
Chris@1447 24 that crash or won't load
Chris@1447 25
Chris@1447 26 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 27 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 28 real improvement, unfortunately it does mean that the initial
Chris@1447 29 padding in mp3 file load has changed from previous versions, which
Chris@1447 30 may mean some sessions saved in previous versions are no longer
Chris@1447 31 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 32 format of record, because of differences like this between
Chris@1447 33 decoders. The previous behaviour is still available as a preference.
Chris@1447 34
Chris@1470 35 - Add new Hybrid normalisation type for spectrogram and colour 3d
Chris@1470 36 plot layers. This normalises each column to its peak value and then
Chris@1470 37 scales the normalised values by the log of the peak in order to
Chris@1470 38 restore some distinction in scale between columns with different
Chris@1470 39 levels. It can provide quite visually clear results.
Chris@1470 40
Chris@1447 41 - Add function to subdivide time instant layers into regular
Chris@1447 42 intervals (and its inverse)
Chris@1447 43
Chris@1447 44 - Add new preference for default colour scales
Chris@1447 45
Chris@1447 46 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 47 and for the main volume control
Chris@1447 48
Chris@1447 49 - Finally switch the Windows built to 64-bit by default (with
Chris@1447 50 adapters to run either 32- or 64-bit plugins)
Chris@1451 51
Chris@1447 52
Chris@1072 53 Changes in Sonic Visualiser 2.5 since the previous release 2.4.1:
Chris@1072 54
Chris@1072 55 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 56 timing units
Chris@1072 57
Chris@1072 58 - Fix failure to reload note layers from session file
Chris@1072 59
Chris@1072 60 - Use a more sensible scale for the play-speed dial
Chris@1072 61
Chris@1072 62 - Fix crash when importing very wide CSV files
Chris@1072 63
Chris@1072 64 - Fix generation of wrong layer type from some CSV files
Chris@1072 65
Chris@1072 66 - Fix failure to export last instant in a time-instant layer
Chris@1072 67
Chris@1457 68
Chris@876 69 Changes in Sonic Visualiser 2.4.1 since the previous release 2.4:
Chris@876 70
Chris@876 71 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 72
Chris@1457 73
Chris@714 74 Changes in Sonic Visualiser 2.4 since the previous release 2.3:
Chris@714 75
Chris@776 76 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 77 gesture (where available)
Chris@776 78
Chris@716 79 - Make the octave numbering into a configurable option, and change
Chris@716 80 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 81 now it labels middle-C as "C4", a more common standard in the world
Chris@776 82 outside MIDI sequencer software. The previous system is available
Chris@776 83 as an option in the Preferences. This affects only the visible
Chris@776 84 labels: there is no change to analysis or to the file format
Chris@714 85
Chris@714 86 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 87 set to Hz will now acquire a playback toggle control; this control
Chris@714 88 is off by default, but if it is switched on, the curve will be
Chris@714 89 played back using a variable-frequency sound generator
Chris@714 90
Chris@714 91 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 92 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 93
Chris@714 94 - Change the default playback sample for note layers from piano to an
Chris@714 95 electric piano with sustain. The piano sample is still available,
Chris@714 96 and any sessions saved using it should continue to use it
Chris@714 97
Chris@867 98 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 99 cancelling a transform results in a part-complete layer rather than
Chris@867 100 removing the results
Chris@867 101
Chris@790 102 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 103 the existing ones to cycle the current pane)
Chris@790 104
Chris@790 105 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 106 themselves randomly when new layer added, layers being ordered
Chris@791 107 randomly when saving and reloading a session
Chris@790 108
Chris@848 109 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 110 temporary and template directories on Windows
Chris@848 111
Chris@714 112 - Shade the start and end of the main audio file, to make them easier
Chris@714 113 to see for files that start or end in silence
Chris@714 114
Chris@714 115 - Speed up rendering and scrolling in time-value layers
Chris@714 116
Chris@714 117 - Make it possible to import CSV files directly into Note layers by
Chris@714 118 adding Pitch as a data type in the CSV file import dialog
Chris@675 119
Chris@856 120 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 121 layer edit dialog
Chris@856 122
Chris@848 123 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 124 is the first release in which the official builds use Qt5 for all
Chris@848 125 platforms.
Chris@848 126
Chris@675 127
Chris@675 128 Changes in Sonic Visualiser 2.3 since the previous release 2.2:
Chris@675 129
Chris@675 130 - Add a startup welcome dialog that also explains what SV makes
Chris@675 131 network connections for and allows user to forbid them
Chris@675 132
Chris@675 133 - Add "Export Audio Data" feature
Chris@675 134
Chris@675 135 - Show piano keyboard scale in note and time-value layers as well
Chris@675 136 as spectrogram, where vertical scale is log Hz; also show
Chris@675 137 numerical scale in note and region layers when not auto-aligned
Chris@675 138
Chris@675 139 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 140 for CSV file format dialog when file has lots of columns
Chris@675 141
Chris@675 142 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 143 state
Chris@675 144
Chris@675 145 - Reduce number of timer wakeups when idle
Chris@675 146
Chris@675 147 - Add American English translation and make choice of translation
Chris@675 148 into a preference (defaulting to system locale)
Chris@675 149
Chris@675 150 - Permit installation to non-default location with Windows installer
Chris@675 151 build
Chris@714 152
Chris@608 153
Chris@608 154 Changes in Sonic Visualiser 2.2 since the previous release 2.1:
Chris@608 155
Chris@608 156 - Build with support for hidpi ("retina") text on OS/X
Chris@675 157
Chris@608 158 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 159 via libsndfile
Chris@675 160
Chris@608 161 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 162 others
Chris@675 163
Chris@608 164 - Fix failure to open files specified on command line (or via
Chris@608 165 Open With) on Windows
Chris@675 166
Chris@608 167 - Reset cyclical counters and switch back to navigate mode when
Chris@608 168 a new session is started
Chris@579 169
Chris@675 170
Chris@579 171 Changes in Sonic Visualiser 2.1 since the previous release 2.0.1:
Chris@579 172
Chris@579 173 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 174
Chris@579 175 - Make it easier to see results from transforms that return a single point
Chris@675 176
Chris@579 177 - Make labelling clearer on time-value layers
Chris@675 178
Chris@579 179 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 180
Chris@579 181 - Update code to build against Qt5
Chris@523 182
Chris@675 183
Chris@523 184 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523 185
Chris@523 186 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 187
Chris@675 188
Chris@512 189 Changes in Sonic Visualiser 2.0 since the previous release 1.9:
Chris@512 190
Chris@512 191 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 192 obsolete QuickTime audio file reader)
Chris@512 193
Chris@512 194 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 195 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 196 directly. Release builds use Sord/Serd rather than Redland
Chris@512 197
Chris@512 198 - Add a fullscreen mode on the F11 key
Chris@471 199
Chris@675 200
Chris@471 201 Changes in Sonic Visualiser 1.9 since the previous release 1.8:
Chris@471 202
Chris@471 203 - Add session templates; save session as template; apply template to
Chris@471 204 session
Chris@471 205
Chris@471 206 - Tidy up the file open logic so as to remove the dialog asking how
Chris@471 207 to open a file, where possible
Chris@471 208
Chris@471 209 - Various bug fixes.
Chris@394 210
Chris@675 211
Chris@394 212 Changes in Sonic Visualiser 1.8 since the previous release 1.7.2:
Chris@394 213
Chris@394 214 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 215 providing better integration with the desktop generally (Dan Stowell)
Chris@394 216
Chris@394 217 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 218
Chris@407 219 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 220 selection of purpose for each column
Chris@407 221
Chris@394 222 - Text overlays are now easier to read on dark backgrounds
Chris@394 223
Chris@394 224 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 225
Chris@394 226 - A crash when starting a new session or exiting the application
Chris@394 227 after loading a session with saved alignment data has been fixed
Chris@394 228
Chris@394 229 - The duplication of right-button menu functions when multiple files
Chris@394 230 were loaded has been fixed
Chris@394 231
Chris@394 232 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 233
Chris@394 234 - The codebase has been reorganised into libraries and a configure
Chris@394 235 step added. It should be easier to build and maintain on OS/X and
Chris@394 236 Linux than previously, although it won't make much difference on
Chris@394 237 Windows.
Chris@394 238
Chris@397 239 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 240
Chris@675 241
Chris@394 242 Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1:
Chris@394 243
Chris@394 244 - The time-value layer now has an origin line and an option to
Chris@394 245 show derivatives (change from one point to the next) rather than
Chris@394 246 raw values
Chris@394 247
Chris@394 248 - A static initialiser race has been fixed, possibly fixing an
Chris@394 249 occasional crash on startup in Windows
Chris@394 250
Chris@394 251 - A crash when pressing Play straight after New Session has been
Chris@394 252 fixed
Chris@394 253
Chris@675 254
Chris@394 255 Changes in Sonic Visualiser 1.7.1 since the previous release 1.7:
Chris@394 256
Chris@394 257 - The RDF importer does a better job of assigning labels to layers,
Chris@394 258 layers to panes, and values to labelled regions
Chris@394 259
Chris@394 260 - Interactive editing in the Text layer benefits from the same
Chris@394 261 improvements as made in 1.7 to Note and Region layers
Chris@394 262
Chris@394 263 - The layer data editor window has a text search feature
Chris@394 264
Chris@394 265 - The main window status bar now shows the last label to have passed
Chris@394 266 the playback position in the current layer, at the right end of the
Chris@394 267 status bar
Chris@394 268
Chris@394 269 - The Russian translation has been updated (thanks Alexandre)
Chris@394 270
Chris@675 271
Chris@394 272 Changes in Sonic Visualiser 1.7 since the previous release 1.6:
Chris@394 273
Chris@394 274 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 275 can be used to create Note and Region layer items whose time
Chris@394 276 extents correspond to the current selection(s)
Chris@394 277
Chris@394 278 - Interactively editing points in the Note and Region layers
Chris@394 279 now works much more smoothly
Chris@394 280
Chris@394 281 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 282 timing (importing MIDI files using with the more common
Chris@394 283 timebase-based timing was already supported)
Chris@394 284
Chris@394 285 - Time values throughout the display may optionally be shown in
Chris@394 286 seconds and frames at various frame rates
Chris@394 287
Chris@394 288 - A crash on exit in Windows has been fixed
Chris@394 289
Chris@394 290 - A very unobtrusive user survey is now included
Chris@394 291
Chris@394 292 - Various other bug fixes.
Chris@394 293
Chris@675 294
Chris@394 295 Changes in Sonic Visualiser 1.6 since the previous release 1.5:
Chris@394 296
Chris@394 297 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 298 scale and linear interpolation options.
Chris@394 299
Chris@394 300 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 301 and Colour 3D Plot, which improves readability for some data.
Chris@394 302
Chris@394 303 - Further performance improvements have been made to Colour 3D
Chris@394 304 Plot.
Chris@394 305
Chris@394 306 - Various other bug fixes.
Chris@394 307
Chris@675 308
Chris@394 309 Changes in Sonic Visualiser 1.5 since the previous version 1.4:
Chris@394 310
Chris@394 311 - You can now insert time instants, time values, and notes using
Chris@394 312 a MIDI device during playback. If a time value or note layer is
Chris@394 313 current it will be used for insertion (giving a value equal to
Chris@394 314 the pitch class, or the played note, respectively); otherwise an
Chris@394 315 existing or new time instants layer will be used just as it is
Chris@394 316 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 317 device should give better timing than using the PC keyboard.
Chris@394 318
Chris@394 319 - There is a new Activity Log window with a (purely informative) list
Chris@394 320 of events and user interactions that happen while SV is running.
Chris@394 321
Chris@394 322 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 323 this is now the default (being much faster than the 4x oversampled
Chris@394 324 method). The previous default is still available as a preference.
Chris@394 325
Chris@394 326 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 327 calculated by plugins) is substantially faster in this release.
Chris@394 328
Chris@394 329 - Spectrogram display is now faster in many circumstances.
Chris@394 330
Chris@394 331 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 332
Chris@394 333 - SV will take into account RDF plugin descriptions, if available,
Chris@394 334 in order to make somewhat better decisions about display of plugin
Chris@394 335 outputs (for example, placing segmentation data into a layer with
Chris@394 336 segmentation plot type).
Chris@394 337
Chris@394 338 - You can now switch layers by clicking on the spare area at the left
Chris@394 339 end of the pane that is also used for the current pane indicator.
Chris@394 340
Chris@394 341 - The vertical black lines dividing segments in the time value
Chris@394 342 layer's segmentation plot style are now optional.
Chris@394 343
Chris@394 344 - Several widget layout bugs on OS/X have been fixed.
Chris@394 345
Chris@394 346 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 347 been fixed.
Chris@394 348
Chris@394 349
Chris@394 350 New features in Sonic Visualiser 1.4 since the previous version 1.3:
Chris@394 351
Chris@394 352 - SV now has a Region layer type, used for display of features with
Chris@394 353 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 354 for features.
Chris@394 355
Chris@394 356 - Layer data can now be imported from RDF described using the Audio
Chris@394 357 Features Ontology, as well as from the existing text file types. SV
Chris@394 358 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 359 somewhat simplistic manner at present.
Chris@394 360
Chris@394 361 - You can search for transforms by text in the new "Find a Transform"
Chris@394 362 dialog. This searches both installed plugins, and plugins that have
Chris@394 363 not been installed but that have descriptions available on the
Chris@394 364 semantic web.
Chris@394 365
Chris@394 366 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 367 and colour 3d plot layers.
Chris@394 368
Chris@394 369 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 370 as well as its own compressed-XML .sv format. Files with extension
Chris@394 371 .xml that contain suitable session data will be loaded as sessions.
Chris@394 372 Note that .xml extension files still do not show up in the default
Chris@394 373 file load filter. This is intentional, as there may be any kind of
Chris@394 374 data in them -- if you want to load uncompressed session files from
Chris@394 375 XML, you need to know you're doing it.
Chris@394 376
Chris@394 377 - Several crashes and other bugs have been fixed.
Chris@394 378
Chris@675 379
Chris@394 380 Changes in Sonic Visualiser 1.3 since the previous version 1.2:
Chris@394 381
Chris@394 382 - There is a new spreadsheet-style data viewer and editor for
Chris@394 383 viewing and editing the data in some types of annotation layer.
Chris@394 384
Chris@394 385 - Alignments are now saved to the session file.
Chris@394 386
Chris@394 387 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 388
Chris@394 389 - You can now hold Shift while dragging to move an item, in order
Chris@394 390 to override the initial drag resistance introduced in 1.2.
Chris@394 391
Chris@394 392 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 393
Chris@394 394 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 395
Chris@394 396 - Several other bug fixes.
Chris@394 397
Chris@675 398
Chris@394 399 New features in Sonic Visualiser 1.2, since the previous version 1.0:
Chris@394 400
Chris@394 401 - SV now supports time-alignment of multiple performances of a work
Chris@394 402 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 403 plugin is installed. When alignment is switched on and more than one
Chris@394 404 audio file is open, SV will assume that all open files are
Chris@394 405 differently timed performances of the same work, and will calculate
Chris@394 406 time alignments for them. Playback will then play only a single file
Chris@394 407 at a time, and the playback cursors in other files will track at the
Chris@394 408 varying speeds to try to ensure that each is at the same point in the
Chris@394 409 underlying score. This enables effective comparison of several such
Chris@394 410 files, as well as a meaningful way to switch from one performance to
Chris@394 411 another during playback (ensuring that the switch happens at the
Chris@394 412 correct point in the performance being switched to).
Chris@394 413
Chris@394 414 - There is a new Image layer, which can display images from the
Chris@394 415 local filesystem or retrieved via HTTP or FTP.
Chris@394 416
Chris@394 417 - A new measurement tool has been added. With the measurement tool
Chris@394 418 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 419 scale values for its start and end corners and its size. You can
Chris@394 420 have any number of measurements present at once; they are associated
Chris@394 421 with the top layer, their scale values depend on the scale for that
Chris@394 422 layer, and they are only shown when that layer is at the top and the
Chris@394 423 measurement tool is active. Measurements are saved and reloaded in
Chris@394 424 the session file. Drawing measurements can be undone and redone, and
Chris@394 425 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 426 that the measurement tool shows the scale values associated with the
Chris@394 427 pixel positions of the mouse when dragging, not any values associated
Chris@394 428 with actual features present in the audio or its analysis (e.g. the
Chris@394 429 values are not rounded to the nearest spectrogram bin).
Chris@394 430
Chris@394 431 - You can double-click using the measurement tool in the spectrogram
Chris@394 432 to get an instant measurement rectangle for a feature. This is a
Chris@394 433 purely graphical feature that works by calculating the boundary of a
Chris@394 434 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 435 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 436 scheme etc of the spectrogram will (by design) affect the
Chris@394 437 measurements obtained this way.
Chris@394 438
Chris@394 439 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 440 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 441 some refinement).
Chris@394 442
Chris@394 443 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 444 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 445 in the spectrum. Both of them show more information as text
Chris@394 446 alongside the cursor than previously.
Chris@394 447
Chris@394 448 - There is a new Erase tool for erasing individual points from an
Chris@394 449 editable layer.
Chris@394 450
Chris@394 451 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 452 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 453 to avoid clashes with window manager shortcuts and to make them
Chris@394 454 easier to use and remember
Chris@394 455
Chris@394 456 - The playback controls are now in a Playback menu as well as the
Chris@394 457 toolbar.
Chris@394 458
Chris@394 459 - There is a new key and mouse control reference under Help (or press
Chris@394 460 F2).
Chris@394 461
Chris@394 462 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 463
Chris@394 464 - All of the single-colour layers (waveform, time values etc) now
Chris@394 465 allow you to define your own colours as well as using the built-in
Chris@394 466 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 467
Chris@394 468 - When you add a new single-colour layer it will use a default colour
Chris@394 469 that is not yet in use in another layer (if there is one).
Chris@394 470
Chris@394 471 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 472 a set of lighter colours in the default colour palette that use black
Chris@394 473 backgrounds by default).
Chris@394 474
Chris@394 475 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 476 small number of grey shades.
Chris@394 477
Chris@394 478 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 479 it now leaves the point that was in the centre of the visible area in
Chris@394 480 the centre after zoom, instead of the point that was in the centre of
Chris@394 481 the linear range corresponding to the visible area.
Chris@394 482
Chris@394 483 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 484 Invert Vertical Scale button.
Chris@394 485
Chris@394 486 - There's a new Layer Summary window which shows the panes and
Chris@394 487 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 488
Chris@394 489 - Each pane now has an [X] button at its top left, which removes that
Chris@394 490 pane when clicked.
Chris@394 491
Chris@394 492 - There's a new Solo play mode toggle button; when active, only the
Chris@394 493 currently selected pane is played. This is also the default when
Chris@394 494 time alignment is in use.
Chris@394 495
Chris@394 496 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 497 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 498 even if there is no time instants layer for them to align to (they
Chris@394 499 align to the time ruler instead and so jump in steps of a size
Chris@394 500 dependent on the zoom level).
Chris@394 501
Chris@394 502 - You can now export note layers to MIDI.
Chris@394 503
Chris@394 504 - MIDI note velocity is partially supported. Note velocity is
Chris@394 505 retained when importing and exporting MIDI and is used in playback,
Chris@394 506 but it is not yet shown in the display and cannot yet be edited.
Chris@394 507
Chris@394 508 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 509 other programs such as file managers or web browsers.
Chris@394 510
Chris@394 511 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 512 moment) are now decoded in a background thread so you can see the
Chris@394 513 start of the track without waiting for the rest to decode.
Chris@394 514
Chris@394 515 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 516 supported by QuickTime.
Chris@394 517
Chris@394 518 - There is now an option to resample audio files on import if they
Chris@394 519 don't match the samplerate of the first file loaded. By default this
Chris@394 520 is switched off, as it affects the visible waveform. The default
Chris@394 521 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 522 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 523 on playback and showing the waveforms at different resolutions
Chris@394 524 according to each one's underlying rate) and there probably never
Chris@394 525 will be.
Chris@394 526
Chris@394 527 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 528 to do as it simply loads all the files in the playlist at once.
Chris@394 529
Chris@394 530 - SV now has various options for how to number tapped time instants
Chris@394 531 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 532
Chris@394 533 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 534 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 535
