Another " unfavorite things " is the " plug-ins " setup/preferences.

The other day i set up an AU plug in to play the BASS track and another AU plug to play the PIANO track in a song.

Now every time i open a song that AU plug in plays although in the Patches pane ( extreme upper right hand side ) shows Acoustic Bass and Acoustic Piano and in the Plugins pane it shows NO plug-in.

I selected plug-ins and set the BASS and PIANO tracks to none. .

Those two plug-ins still play.

I find the " preference " settings for plug-ins somewhat misleading and more complicated then it should be .
