Camelot Codes to Keys

For a brief time, back when I was radio DJ, a station I worked at experimented with using “key segues”, whereby a recorded sounder would transition from a song played in one key to a song in another. Thus: Song in C fades -> sounder transitions from C to A minor -> seg next Song in A minor.

It was horrendous.

Anyway. Since I was an Actual Musician (few and far between in radio), it was my job to assign the correct key for each song we played. Which essentially meant that I sat in a studio a couple of times a week with a CD player and a Casio keyboard and diddled around until I determined the key of each song we added that week.

Nowadays, a lot of DJs use the musical key of the tracks they play to create “harmonic mixes”; tracks are mixed or segued according to harmonic rules. Some DJs probably aren’t musically inclined either, so there is software and databases and such that can supply the key for their tracks. Then all they have to do is check the Camelot chart to see what might sound good.

(This, of course, is not perfect, since pitches can vary. Which is what made my old station’s experiments with key segues so cringey. We had CD players that could adjust for pitch, but nobody wanted to spend that much time on creating perfectly harmonic segues. But, whatever.)

I heard from a Correspondent who uses this system. He has the Camelot codes in his iTunes tracks’ Comments tags. These are codes that represent 24 musical keys and look like this: 1A, 2A, 3A…10B, 11B, 12B:

He wants to convert the Camelot codes to the actual key. So here is a script that will do that: (more…)

Find Tracks with Multiple Artworks

This will corral all the tracks in the Music library that have more than one assigned artwork to a new playlist (whose name you supply; any existing playlist(s) with that name will be deleted beforehand):

tell application "iTunes"

try

set newPlaylistName to text returned of (display dialog ¬

"Enter a name for the playlist:" default answer "Multi-artwork tracks")

on error

return

end try

try

delete (every playlist whose name is newPlaylistName)

end try

set newPlaylist to (make new playlist with properties {name:newPlaylistName})

set musicLibrary to (get some playlist whose special kind is Music)

repeat with i from 1 to (index of last track of musicLibrary)

try

set aTrack to track i of musicLibrary

if (count of artworks of aTrack) > 1 then

try

duplicate aTrack to newPlaylist

end try

end if

end try

end repeat

display dialog "Done" buttons {"OK"} default button 1

end tell

Open this in Script Editor by clicking the little script icon. Save it named whatever you like as a Script Bundle in your ~/Library/iTunes/Scripts/ folder so that it will be listed in the iTunes Script menu. Launch the script and enter a name for the playlist; the default is “Multi-artwork tracks”; press OK.

Close a Playlist Window and Select Its Playlist

If it really drives you crazy that after closing a playlist window iTunes is compelled to put focus on the entire Music library, use the following script to close the frontmost playlist window and thereafter select the playlist it had contained in the main window:

tell application "iTunes"

try

set frontPlaylistWindow to front playlist window

set thePlaylist to view of frontPlaylistWindow

close frontPlaylistWindow

reveal thePlaylist

end try

end tell

Click on the little AppleScript icon above to open the script in Script Editor at your house—don’t copy the text in the browser.

Save the script as a Compiled “.scpt” with Script Editor named whatever you like in your [home]/Library/iTunes/Scripts/ folder so it can be launched from the iTunes Script menu. You may want to assign it a keyboard shortcut.

When run, it will get a reference to the front playlist window; if none is open, the script will fail silently. It will proceed to get a reference to the playlist contained by the playlist window, close the playlist window and finally select (reveal) the playlist.

Playlist Windows

iTunes 12.6 has brought back Playlist windows and, judging from the reaction in my Twitter feed, they’re receiving a hearty welcome back. Couple of things, though: 1) The names of the open Playlist windows are not listed in the iTunes “Window” menu and 2) window names are blank for any Apple Music playlists opened as Playlist windows; they actually default to the name “iTunes” but this isn’t displayed either To be clear, the AppleScript name for the window of a subscription playlist is “iTunes” and not the name of the playlist. (Update: And now I’m not seeing this at all and all seems correct as far as names go; don’t know what I was seeing previously!)

I’m not so much concerned about the latter thing. But if you have a batch of Playlist windows open it can be an ordeal to select one you’d like to work in. This script will list all open Playlist windows in a choose from list panel so one can be chosen and then made frontmost:

tell application "iTunes"

if (count of playlist windows) < 2 then return

set windowList to playlist windows

set nameList to name of view of playlist windows

try

set chosenName to (choose from list nameList)

if chosenName is false then error

on error

return

end try

set chosenName to (chosenName as text)

repeat with i from 1 to (count of nameList)

if chosenName is item i of nameList then select item i of windowList

end repeat

end tell

Click on the little AppleScript icon above to open the script in Script Editor at your house—don’t copy the text in the browser.

Save the script as a compiled Script (“.scpt”) with Script Editor named whatever you like in your [home]/Library/iTunes/Scripts/ folder. When there are too many Playlist windows open and you can’t find any real estate to click on, launch the script to select the one you want brought to the front.

(Update: Of course, after I post this I immediately discovered that you can Command-tilde (~) through open Playlist windows.)

Preserve a Genius Shuffle Playlist

One of my favorite features of iTunes is Genius Shuffle. By pressing the Option key and Space Bar simultaneously, iTunes will construct a 25-track Genius-type playlist in Up Next around a “seed” track it chooses at random from your library. Typically, I’ll slap Option-Space Bar repeatedly until I get the type of songs I’m in the mood for. Sometimes though—because I have an itchy DJ finger—I’ll abandon the current set of tracks after a few songs and create a new different Genius Shuffle arrangement. But still I’d like to have been able to save the playlist I had abandoned because, at least for a while there, I really liked it. Well, you can do this with AppleScript.

When iTunes is playing Up Next like this the track references are available in current playlist. It is a simple matter to copy them to a new playlist. The script I’ve listed below asks for a name for the new playlist; I’ve set the default answer in the display dialog to “Genius Shuffle” and when I run the script I’ll keep that in the name, for example: “Rockin’ Blues – Genius Shuffle”, “70’s Funk – Genius Shuffle”, and so on.

tell application "iTunes"

try

if not (exists current playlist) then error

set opt to (display dialog “Enter a name for the new playlist:” default answer "Genius Shuffle")

set newP to (make new user playlist with properties {name:text returned of opt})

duplicate every track of current playlist to newP

reveal newP

on error

return

end try

end tell

Click on the little AppleScript icon above to open the script in Script Editor at your house—don’t copy the text in the browser.

Save the script as a Compiled “.scpt” with Script Editor named whatever you like in your [home]/Library/iTunes/Scripts/ folder.

One issue is that if any of the tracks in Up Next are “dead” tracks then the script will fail (a repeat loop could duplicate each track individually to filter dead tracks, but I wanted to keep this simple). On the other hand, I think iTunes will ignore dead tracks when it creates a Genius Shuffle playlist.

Also I would only run this after creating a Genius Shuffle playlist; it doesn’t make much sense to run it when anything else is playing.

How to Blankety-Blank Blank

As you may have noticed, the last few versions of iTunes have been gradually “contextualizing” the interface. For example, the Info window will only display the kind-pertinent tags for a selected track. (Remember: it used to be that the Info window displayed the same configuration for any track; so that Music tracks had access to TV-kind tags, like Season and Episode ID, and so on.)

Despite this, when the iTunes browser window is in Songs view, non-contextual tags can still be displayed and tracks can still be sorted using them. This is because every track entry in the database has the same columns whether they are used for that kind of track or not. Thus, for example, Music tracks have “season” and “episode ID” track tags even though they are not used for Music tracks.

AppleScript can access these tags and a script of mine, Sort by Artwork Size, can store the dimensions of a track’s artwork (eg, “600×600”) to the Category or Episode ID tag. Tracks can then be sorted by their “artwork size” or those tags can be used when constructing Smart playlist criteria.

However, since these tags can’t be accessed very easily it is a chore to clear them if they are no longer required. So here’s a script that will blank a particular tag of all the selected tracks. In this case, it blanks the episode ID tag. For people who already know how to script such a thing, this will be easy as pie. But, if your skill level as a scripter is below Dabbler, you may want to use this as a template for your own blanking scripts: (more…)

Hassle-Free Playlist Description

One of the neat things that Apple added to iTunes not so long ago is the user-editable description that is available for regular Playlists (Smart, Folder, Genius and Master library playlists do not have this option) and is visible when the Playlist is in Playlist View. You can edit this description by clicking the Playlist’s “Edit Playlist” button. But when you do this, the iTunes interface changes: a column appears at the right edge of iTunes listing the current tracks in the playlist to which you can drag tracks. It also will change the (now center column) browser window to display the full Music library, which totally discombobulates me.

I do not always care for this when I just want to edit the Playlist’s description. I’d prefer to do so without shaking up the interface. This script will do it:

tell application "iTunes"

try

set thisPlaylist to (get view of front browser window)

tell thisPlaylist

if special kind is not none or smart or genius or shared then error

end tell

on error

beep

return

end try

set defaultAnswer to (get thisPlaylist’s description)

if defaultAnswer is missing value then set defaultAnswer to “”

set newDescription to text returned of ¬

(display dialog "Enter the description text for the playlist" & return ¬

& thisPlaylist’s name default answer defaultAnswer)

try

set thisPlaylist’s description to newDescription

end try

end tell

Save this named whatever you like to your [home]/Library/iTunes/Scripts/ folder so that it will appear in the iTunes Script menu. Select a playlist and launch the script by selecting it from the Script menu. It will quit if the selected playlist is the wrong kind. It will display the current description for the playlist if it exists, otherwise the text field will be blank. Enter up to 255 characters, which is the most that the description can accept, and then click “OK”.

Give this a keyboard shortcut to maximize your quality of life.

Reset Plays MIA

[UPDATE: iTunes 12.4.1, released June 2, 2016, restores the Reset Plays feature. The “Reset” button is located in the track’s Get Info window’s “Details” tab adjacent to the play count entry.

Of course, the script below is still serviceable.]

Looks like the “Reset Plays” command is MIA in iTunes 12.4. Here’s a script that will reset the played count of each selected track to 0 and remove its played date.

tell application "iTunes"

set sel to selection

if sel is {} then return — nothing selected

repeat with thisTrack in sel

— use try blocks to fail gracefully if problem

try

set thisTrack's played count to 0

end try

try

set thisTrack's played date to missing value

end try

end repeat

end tell

Click on the script icon to open this in Script Editor on your machine. From Script Editor’s File menu, click “Save…”. In the Save Panel, enter a name for the script, like “Reset Plays”, and save it to your [username]/Library/iTunes/Scripts/ folder (if no “Scripts” folder exists, create one). Once saved to this folder, the script will appear in iTunes’ Script menu. To use, select the track(s) in iTunes whose plays you want to reset and then choose the “Reset Plays” script in the Script menu.

A more advanced version of this script is available as a download from this page.

Alternatively, you can use Add or Subtract Play Count, New Last Played Date, or New Play Count. Each has some capacity to change a track’s Plays.

There still seems to be a bug regarding changing the Plays of Matched/Uploaded tracks in the cloud, whereby the played count reverts to whatever it was before being “artificially” set with AppleScript (or other means). I couldn’t say if that issue is related to the disappearance of “Reset Plays”.

Delete Other Artwork

iTunes is able to accommodate more than one image for a track entry’s artwork. What hasn’t always been obvious is that the first artwork in an array of artworks in a track is the “display” artwork. Any additional artwork in the artworks array are spares. Modern versions of the iTunes Get Info Artwork panel now label images as “Album Artwork” and “Other Artwork”.

Some people think that these “Other Artwork” have to go.

It is a simple matter to simply remove the other artwork from a track entry with an AppleScript. Here’s one now that goes through each track in a selection and repeats through its artworks (if there’s more than one artwork), removing the last artwork until there is only the first one left:

tell application "iTunes"

set selectedTracks to selection of front browser window

repeat with i from 1 to (count of selectedTracks)

set thisTrack to item i of selectedTracks

tell thisTrack

try

if (count of its artworks) > 1 then

repeat until ((count of its artworks) is 1)

delete its last artwork

end repeat

end if

end try

end tell

end repeat

end tell

Click the script icon above to download this script to Script Editor at your house and click “New Script” to allow it to open. Save it named whatever you like in your ~/Library/iTunes/Scripts/ folder (or wherever you put them). Select some tracks in iTunes and launch the script.

There’s always the kid in the front who wants to know why you don’t make a script like this that just works on the entire library. Well: iTunes can be kind of touchy when AppleScripting a large amount of artwork stuff. It may “go modal” as it updates its database and under such circumstances may block an AppleScript from continuing its operation. So I purposely used the selection object so that the script can be used piecemeal on a small batch of tracks at a time. Additionally, you might want to eyeball the “Other Artworks” of a track before you start blindly mowing them all down; in which case having to select the tracks manually compels you to be in control.

The routines are in a try block to skip over errors because of what I mentioned above about modality and also in case there’s some image gunk in there that causes trouble. Because images downloaded from the internet that you use as album artwork are always pristine, right?

Play Selected Track and Cue Next

A Correspondent inquired about a script that would play a selected track in iTunes through to the end and then stop and then select the next track but not play it. In such a way, a playlist containing sequential musical cues required for a theatrical performance could be fired one track at a time, via the script, without a lot of stopping and mouse-clicking and swearing backstage (“Up yer scrim!”, “Purple behind!”).

This is such a script:

— Play Selected Track and Cue Next

tell application "iTunes"

— get the single selected track and play it

set theSelection to selection

if length of theSelection is 1 then

set theTrack to item 1 of theSelection

try

play theTrack with once

on error

## beep

return

end try

— the selected track is playing, now do some other stuff…

— get the playlist

set thePlaylist to (get view of front window)

— stash current fixed indexing value

set curfi to fixed indexing

— we want free indexing not fixed indexing

set fixed indexing to false

— compute next track’s index

set idx to (get index of theTrack)

if (idx = (count of tracks of thePlaylist)) then

set idx to 1

else

set idx to (idx + 1)

end if

— select the next track in the playlist

reveal track idx of thePlaylist

— restore fixed indexing to whatever it was before

set fixed indexing to curfi

end if

end tell

What you’d want to do is save this with Script Editor, named whatever you like, with a File Format of “Script” and put it in your [Home]/Library/iTunes/Scripts/ folder so it appears in iTunes’ Script menu.

Prepare a playlist and select its first track. When it’s time to actually play the track, don’t use any iTunes play controls; instead, fire the script. The script will play the selected track, figure out which track is next in sequence, select it, and then quit. iTunes will stop when the current track has finished by virtue of that with once parameter on the play command. When it’s time to play the next track, which is now the selected track, fire the script to play it and select the next track. And so on.

While assigning this script a keyboard shortcut will be convenient if you can keep a hand near the keyboard, something that could fire this via a physical remote control would be super boss. Under such circumstances, you may prefer—or it may be necessary—to save the script with a File Format of “Application”.
