Sixchannel,
YES it is a real "danger" smile 16 Tracks Happened! Hurrah PG team!

Sixchannel,
Do not worry, your machine will pull it! As it is, it generates once (unless you regenerate manually). Once regenerated it is a solid audio - acts similar to "Freezed" track.

The discussion is about adding an option to automate regeneration.
Not to have it by default.

Also, you do not have to use all 16 tracks! You can use and have displayed only one extra track (or 3 or 5 extra tracks) if you wish. It is very flexible and should accommodate almost any setup.
