I incorporated your script and suggestions. I will update the post with the new script.

FYI, I handled the conversion to text by using a list (Applescript's version of an array). I just set up a list:
set all_keys to {"8B-C", "8A-Am", "3B-Db"}

Then when I have the integer value from djay, I use that to grab the one I want:
set key_djay_string to item (key_djay + 1) of all_keys

The +1 is necessary because Applescript does not start indexing at 0 but at 1. So for a key_djay of 0 we want item 1 of the list.

Thanks for the info. I've edited your script to copy over key data instead of bpm. It copies the key into the Groupings field in iTunes. As written, it will overwrite existing Grouping data.

Here's the script: http://dl.dropbox.com/u/7987233/Get%20key%20from%20Djay.scpt

It records the key data in the form recorded by djay, which are values from 0 to 23. Once the data is in iTunes, it is easy to group together all songs with the same key value and do a batch change to a format more useful for harmonic mixing, such as 1A-G#m.

Here's how the djay key values correlate to key names:

It would be nice to work this conversion into the script to avoid this manual step in iTunes. I'm kind of an Applescript newbie — any suggestions for how to code this? Some kind of "if-then"? If you give me the code for doing one (example: 9 = 12A-C#m) then I can go from there for doing the other 23 values.

I'd like to see this script posted to the following djay forum, either as is or with the proposed addition, since it offers the alternative approach of selecting the tracks in iTunes rather than doing a batch process on the whole djay cached plist.

Thanks again!

set oldGrouping to grouping of myTrack
set grouping to oldGrouping & " " & myKeyData

Glad you find it useful. I found a code snippet that uses the Grouping tag over here: http://dougscripts.com/itunes/itinfo/itunes42info.php

It seems pretty straightforward:
tell myTrack
set grouping to myKeyData
end tell

I'm trying to modify your bpm script to transfer key data into the Groupings field in iTunes. Seems only a few parameters would have to be changed, such as changing BPM to KEY for the code lines that refer to the djay plist.

What parameter(s) need to change on the iTunes side of the code?

Thanks so much!
Rob

I have updated the script to check for manually changed bpm values. This script does not handle key data.
