- Nevertheless, when adding tracks to a session, you typically have an idea - of what you need to use the new tracks for, and Ardour offers you three - choices: -

-
-
Audio
-
An Audio Track is created with a user-specified number of - inputs. The number of outputs is defined by the master bus channel count - (for details see Channel Configuration - below). This is the type of track to use when planning to work with - existing or newly recorded audio.
-
MIDI
-
A MIDI track is created with a single MIDI input, and a - single MIDI output. This is the type of track to use when planning to - record and play back MIDI. There are several methods to enable playback - of a MIDI track: add an instrument plugin to the track, connect the - track to a software synthesizer, or connect it to external MIDI hardware. -

- If you add an instrument plugin, the MIDI track outputs audio instead - of MIDI data. -

-
Audio/MIDI
-
There are a few notable plugins that can usefully accept both Audio - and MIDI data (Reaktor is one, and various "auto-tune" like plugins - are another). It can be tricky to configure this type of track manually, - so Ardour allows you to select this type specifically for use with such - plugins. It is not generally the right choice when working normal - MIDI tracks, and a dialog will warn you of this.

Track Modes

-

- Audio tracks in Ardour have a mode which affects how they behave - when recording: -

-
-
Normal
-
Tracks in normal mode will record non-destructively—new - data is written to new files, and when overdubbing, new regions will be - layered on top of existing ones. This is the recommended mode for most - workflows. -
-
Non-Layered
-
Tracks using non-layered mode will record - non-destructively—new data is written to new files, but when - overdubbing, the existing regions are trimmed so that there are no overlaps. - This does not affect the previously recorded audio data, and trimmed regions - can be expanded again at will. Non-layered mode can be very useful for spoken - word material, especially in combination with - push/pull trimming. -
-
Tape
-
Tape-mode tracks do destructive recording: - all data is recorded to a single file and if you overdub a section of - existing data, the existing data is destroyed irrevocably—there is no - undo. Fixed crossfades are added at every punch in and out point. This mode - can be useful for certain kinds of re-recording workflows, but it not - suggested for normal - use.
-
-normal and non-layered overdubbing comparision -

- The screenshot on the right shows the subtle difference between an overdub - in normal mode (upper track) and one in non-layered mode - (lower track). Both tracks were created using identical audio data.
- The upper track shows a new region which has been layered on - top of the the existing (longer) region. You can see this if you look - carefully at the region name strips.
- The lower track has split the existing region in two, trimmed each new - region to create space for the new overdub, and inserted the overdub region - in between. -

Channel Configuration

-

- Ardour tracks can have any number of inputs and any number of outputs, and the - number of either can be changed at any time (subject to restrictions caused by - any plugins in a track). However it is useful to not have to configure this sort - of thing for the most common cases, and so the - Add Tracks dialog allows you to - select "Mono", "Stereo" and few other typical multichannel presets
- The name of the preset describes the number of input channels - of the track or bus. -

-

- If you have configured Ardour to automatically connect new tracks and - busses for you, the number of outputs will be determined by the number of - inputs of the master bus, - to which the track outputs will be connected.
- For example, if you have a two-channel master bus, then a Mono track has one - input and two outputs; a Stereo track has two inputs and two outputs. -

-

- If you you set Edit > Preferences > Audio - > Connection of Tracks and Busses to manual, then tracks will be left disconnected by default - and there will be as many outputs as there are inputs. It is up to you to connect - them as you wish. This is not a particularly useful way to work unless you are doing - something fairly unusual with signal routing and processing. It is almost always - preferable to leave Ardour to make connections automatically, even if you later - change some of them manually. + Nevertheless, when adding tracks to a session, its content is typically + known, and Ardour offers three choices:

+ + + + + + + + + + + +
AudioAn Audio Track is created with a user-specified number of + inputs. The number of outputs is defined by the master bus channel count + (for details see Channel Configuration). + This is the type of track to use when planning to work with + existing or newly recorded audio.
MIDIA MIDI track is created with a single MIDI input, and a + single MIDI output. This is the type of track to use when planning to + record and play back MIDI. There are several methods to enable playback + of a MIDI track: add an instrument plugin to the track, connect the + track to a software synthesizer, or connect it to external MIDI hardware. +

+ If an instrument plugin is added, the MIDI track outputs audio alongside + MIDI data. +

Audio/MIDIThere are a few notable plugins that can usefully accept both Audio + and MIDI data (Reaktor is one, and various "auto-tune" like plugins + are another). It can be tricky to configure this type of track manually, + so Ardour allows to select this type specifically for use with such + plugins. It is not generally the right choice when working normal + MIDI tracks, and a dialog will warn of this.
Audio or MIDI BusA bus is a pseudo-track where multiple audio tracks can be mixed together + for some common processing before being routed to the Master Bus (which itself + is a bus). A bus doesn't contain any regions or audio/MIDI data, it is fed a + signal by sends from one or multiple other tracks, or + by connecting tracks outputs to + the bus' input. Busses are often used to apply one effect on multiple tracks, + with the benefits of having the same parameters and less computer processing + required as only one instance of the plugin is used.
+ Ardour can differentiate Audio busses from MIDI busses, allowing e.g. one + instrument plugin to be used for several MIDI tracks.
+ A bus output can also be routed to another bus. +
VCAA VCA is a way to group + together tracks or busses to enable grouped-control over gain, solo and mute. + Like the Bus, it does not contain regions, but unlike it, it does not contain + effects either. VCAs are commonly used to group together related tracks (e.g. "drums" + or "vocals") to allow controlling the gain of all those tracks at once in the + mix while retaining their relative gain.
+ VCAs are fed audio by assigning them + to one or more tracks or busses. +
