100 is a single note up and -100 should be a single note down. There are controls but I couldn't figure out a way to access them so I just typed the values in. My impression from other platforms is that plugins manage their own user interface and so even if Garage Band is accessible the plugins may not be. At least this one lets me type in values even if I can't interact with it in any other way. On previous version of Garage Band you could change the key of a track through a native control in the LCD Panel UI near the metronome, but that is now gone and we're left with the longer Audio Units filter process. Some say the quality isn't as good either but I so seldom use pitch shift this way that it's not that big a deal. Lets just say I like to play (and learn) everything in C. Easy enough on my keyboard with transpose but not so much on a real piano :)

Makes sense, thanks. What did you say the change was? I assumed
there'd be a slider and a way to select the old and new keys for the
song, as in something to tell it how many half steps to shift and in
what direction. What is one half step in numbers to GB?

So first you need to select the track you want to add the filter to and
then do Command-I for track info. That hides or shows the track info but
won't move your focus there. You'll have to stop interacting with the
Arrange Layout area and move to the Track Info Group. Your Real
Instrument button should be pressed (as opposed to Master Track. Then
navigate down to the Browse/Edit radio buttons. Select Edit. Navigate
right from there and you'll find the effects for this track (if any).
Typical ones are Noise Gate and Compressor. These are each loaded into
"slots" making an output chain where the effects are applied in the
order listed. An empty slot is listed as Select Effect Popup Button.
Actioning this will give you a list of effect to load into the slot.
These are arranged in two groups - Garage Band Effects and Audio Unit
Effects, listed in alphabetical order. Arrow down past all the Garage
Band Effects and about 15 down in the Audio Unit effects will be the AU
Pitch effect. You can also get there more quickly bu typing A U P which
will drop you just a few items above it. Select that and it's now
inserted into the slot.

Once the filter is inserted garage band will drop your focus on the next
slot so to edit the effect you'll need to VO up once to get to the
AUPitch Group. Interact with that and find the Edit button. Actioning
that pops a new floating window. VO-right a couple times until you are
past the "action image" and you should land on an edit field which reads
"0 contents selected edit text". This is where you type in the amount of
pitch shift you want (initially zero). If the track is playing you will
hear the change as soon as you hit return. The floating window is a bit
problematic in that it doesn't follow the usual command-tilde rules so
once I lose focus I have to go back to the edit button to get back to
it. Likewise I have to close the popup to make the space start playback
again but with a little fussing it's doable.

Hope this helps.

How do you add that, or any, filter to a track?

The only way I could find to do this was by adding the AUPitch filter to
the track. When editing the filter there are four unlabeled inputs. The
first (initially zero) is the amount of pitch to shift. 100 is a full
note up. Give that a try.

Hi all,
I think I sort of got GB down. I have no idea what changed, but things
are working as Ricardo said they should now and I was able to export a
song, with my bass track, as a standard mp3. Now, if I could just drop
the original song a half step and re-record it so I can play it in
G... can I do that, drop the imported mp3 a half step?


Have a great day,
