Recording modes
When you do overdubbing with punch in and out, all changes happen non-destructively. You do however have a choice over what Ardour does when it overdubs. For that you have three recording modes that you can select in the main toolbar.
The Layered mode is the one used by default. When you overdub in layered mode, it creates a new opaque region on top of the existing one. To illustrate that, let’s open the right-click menu above track’s header and switch from the Overlaid mode to the Stacked mode. So when the playhead is above this new region, you only hear the sound from the top layer and you don’t hear the sound from the bottom layer. The layered mode is the most convenient one when you do comping and you want to have easy access to multiple takes.
In the Non-Layered mode, Ardour trims the existing region so that the new one fits right in. Both regions are opaque. This recording mode is best when you don’t want to preserve individual takes. If you didn’t like the take, you can still undo. Or if you made multiple changes after overdubbing and you want to undo, you can select the newer region, delete it from the timeline, and then tweak the edge of either of the two regions to reveal original audio or MIDI.
When you overdub in the Sound-on-Sound mode, Ardour creates a new region in a new layer at the top, but it makes this region transparent. This means that Ardour will play audio or MIDI from all takes at the same time. There are multiple uses for that. One of them is progressively building up a drum track by adding kick drum, toms, snares, and hi-hats in each individual take.
Please note that you can toggle the opacity of stacked regions at any time later. To do that, select a region, go to the main menu and use the Region > Gain > Opaque
toggle. You can do the same in the right-click menu above the region. Or you can just press Alt+0.
