###Bug Fixes:

• Capo's spectrogram display offset has been adjusted to more closely matches the timing of the song you're hearing while zoomed in.
• Capo no longer displays an incorrect pitch on the left of the spectrogram when a song is transposed.
• Note entries no longer play at un-transposed pitch when clicked.
• When loading an existing, transposed song into Capo, the spectrogram no longer appears at its un-transposed position.
• Capo's display now updates properly when the "Jump to Beginning" command is invoked.
• When scrolling quickly, Capo no longer clips out the display of tab entries. Tab entries are also shown immediately in all cases when a document is loaded, and no longer require the window to be resized.
• While dragging the document window, the spectrogram's position now updates more smoothly, with no more jittering.
• While dragging the playhead, it no longer appears to the left of the mouse cursor.
• Upon loading an existing song, Capo no longer shows 'dead space' beyond the end of the spectrogram before the window is first resized.
• The time display once again updates during scrubbing.
• After scrubbing the playhead, a dropped marker will no longer appear to the right of the playhead.
• The time display once again updates in response to jumping between markers.

• Restores the spectrogram display on some affected Macs
• Corrects alignment of the 4- and 5-string instrument tablature display

• Capo no longer fails to respond to keyboard control commands before the Control menu is shown.
• The displayed keyboard modifiers for the defaults no longer include the 'fn' key. (You must delete your preferences to see this fix.)
• When resizing the window during a spectrogram calculation, Capo no longer crashes with an OpenGL assertion.
• When using a mouse with no trackpad attached, Capo no longer shifts the display of the tablature up too high, losing the 1st string in the display.

Bug Fixes:

• Fixes a graphics performance regression introduced in Capo 2.1.8
• After all note entries are deleted, Capo no longer plays those entries back
• Note entries can no longer be dragged outside the spectrogram range
• The playhead no longer plays scrubbing sounds on first click
• Capo will no longer crash on launch if the MIDI subsystem fails to initialize

• Capo now supports the MacBook Pro with Retina display. It looks pretty awesome...
• You can now adjust speed in 1% increments using the Shift-UpArrow and Shift-DownArrow key combinations.
• When dragging markers off the timeline to remove them, the cursor no longer flickers, and the marker no longer lags behind the cursor.
• When creating a loop between adjacent markers, and the cursor is atop a marker, then the loop will be created 'behind' the current marker by default.

• Capo's playhead no longer gets stuck when dragged to the start of the song.
• Capo will no longer output an excessively loud noise when starting playback in certain, random circumstances. (Sorry!)
• When a document's underlying audio file is relocated on disk, Capo now prompts the user to locate the file rather than failing silently or quitting unexpectedly.

• Integrated a new mastering-quality audio slowing engine that significantly improves the clarity of slowed down music.
• Fixed a bug that affected chord entries when a tranposing capo was set up in the note settings.

• Capo's chord markers are no longer incorrect with a pitch adjustment, or a capo set in the note settings
• When the song is transposed, the note entry context menu now contains correct fret position suggestions
• Capo once again handles iTunes song drags on the dock icon with the new iTunes, and in Lion

• Corrects an issue that prevented Apple .m4a audio files from loading
• Fixed the spectrogram scroller appearance
• Addresses a crash that occurs when dragging a song onto Capo's dock icon while it's not already running

• The Esc key functionality to clear the loop has been restored
• Loop related commands have been reorganized in the Command menu, and added to the learning command list
• There is now an Edit menu item for clearing the note entry selection
• Mono audio files no longer fail to load, as they did in 2.1
• When zooming, the view no longer jumps back to the cursor location
• Clicking a deselected note entry now selects it
• When command-clicking a deselected note entry, other selected note entries do not change string position
• Note entry playback volume now also controls the chord marker sounds, and the volume of notes when clicking the spectrogram
• Note entries no longer creep 1px to the left when merely clicking on them

##New Features * The waveform display has now been re-integrated into the UI, and now serves as the primary loop interaction area (i.e. Where you will do your clicking to set/modify loop points.) * You can now export MIDI files from Capo (File > Export Note Entries…), for use in other applications such as Guitar Pro, Sibelius, Logic, etc. * Playback commands may now be re-mapped using either keyboard or MIDI devices. * Using Control > Go To Time…, you can now type in a point in time to jump to. * Dropping, and clicking on chord markers now plays the chord. * The note you are hovering over in the spectrogram is now displayed at the left-hand side of the spectrogram view, along with the existing C1, C2, ... markers.

##Bug Fixes * Spectrograms, waveforms, and chromagrams are now all cached after they're successfully calculated. Now slower systems don't have to suffer (and eat battery) each time a song is loaded. * An improved spectrogram processing front-end now uses a limiter to pull up quieter sections of audio, and keeps loud sections as they are. This results in a "hotter" spectrogram overall, but provides better balance to widely dynamic classical pieces. * When working with audio files at rates beyond 44.1kHz, the MIDI playback no longer sounds out of tune. * Capo's chord detection now correctly reflects the combination of tuning changes and capo settings. * Added missing standard tunings for 5-String Bass, and Banjo. * The spectrogram now takes into account both channels of stereo audio equally. * Dragging loops now snaps precisely to marker locations.

• When shift-clicking markers, the selection now extends to the clicked-on marker.
• Vertical window resizing is now supported.

• Fix a crash that occurred when loading Capo files that contained tabs for instruments outside the default list. This affected all users that saved bass tabs, as the "Bass" instrument is now called "4-String Bass".

• Added tabbing support for 5- and 6-string Basses
• Also added 5-string Banjos
• Capo no longer stretches the tab header image for 4- and 5-string instruments.
• Extended the range of the Capo adjustment from 10 frets to 18 frets.
• Extended the definition of the Ukelele instrument to have 18 frets, to support tenor Ukes.

• Note entries now play as the audio does. You can control the MIDI note volume by holding the option key, and adjusting the volume at the bottom-left of the main window.
• There is now a Notes menu that allows you to adjust the string/fret position of the selected notes. You can also right-click (or control-click) note entries to adjust their position.
• When the song is transposed using the pitch adjustment, entered chords are now properly stored to reflect the un-transposed pitch.

• Double-clicking to create a loop region while audio is playing back will keep the audio looping, but in the newly-created range.
• Pinch zooming on the Magic Trackpad (and built-in trackpads on notebooks) is now enabled.
• The note settings now fade in instead of sliding in, and the pitch/speed settings are no longer still active 'underneath' the note settings.
• The 'forward delete' key now also deletes note entries.
• Restored full functionality to the marker movement, and high-level marker movement commands.

##New Features * Capo now presents your music using a highly detailed spectrogram that is calculated using OpenCL. * You can now enter notes, and tab out a song quickly, by clicking and dragging on the spectrogram. * You can detect the cord at the cursor by clicking on the chord marker button, or tapping the 'k' key. Double-clicking a chord marker allows you to enter a different chord, if the detection is wrong. * Mousing over the tab entry area will disclose settings for your instrument that you're tabbing for. Current selections include Guitar, Bass, Mandolin, and Ukelele—more will follow. You can also choose alternate tunings, and set a capo on your instrument. * Adjusting the pitch of your song will cause the tablature to update.

##Changes * Looping is now achieved by clicking and dragging in the bottom, shaded part of the timeline, and not the main spectrogram. * The waveform display is gone, in favour of the much richer spectrogram. * Holding the option key will change the function of the zoom slider so that you can adjust the spectrogram's intensity.
