3 title: New/Open Session Dialog
7 The initial <dfn>Session</dfn> dialog consists of several consecutive pages:
10 <h2>Open Session Page</h2>
12 On this page, you can open an <dfn>existing session</dfn>. You can also
13 open any <a href="/working-with-sessions/snapshots/">snapshot</a> of a
14 particular session by clicking on the arrow next to the session name to
15 display all snapshots, and then selecting one. If your session is
16 not displayed in the Recent Sessions list, the <kbd class="menu">Other
17 Sessions</kbd> button will bring up a file selection dialog to navigate
18 your hard drive.<br />
19 Alternatively, you can opt to create a <kbd class="menu">New
23 <h2>New Session page</h2>
25 Here you can type in the name of a session, select a folder to save in, and
26 optionally use an existing <a href="/working-with-sessions/session-templates/">template</a>.
29 Under <dfn>Advanced Options</dfn>, you can select whether you wish to create
30 a Master Bus, or a Control Bus, and how many channels you wish either to have.
31 You can also decide whether you want Ardour to automatically connect all inputs
32 to the physical ports of your hardware. Ardour will do so
33 sequentially and in round-robin fashion, connecting the first track's
34 input to the first input of your hardware and so on. When Ardour has used
35 all available hardware inputs, it will begin again with the first physical
37 You can limit the number of channels on your physical hardware that Ardour
41 By default Ardour will connect all tracks and busses to the Master Bus if
42 there is one. However you can also tell it to automatically connect each
43 output to the physical outputs of your interface or sound card, and limit
44 the number of physical outputs used, as above.
47 <h3>Audio/MIDI Setup</h3>
49 <img class="right" src="/images/Audio-MIDI_Setup.png" alt="The Audio+MIDI
53 This page is not displayed if <abbr title="JACK Audio Connection
54 Kit">JACK</abbr> is already running when you start
55 Ardour. It provides a simple interface to configure JACK, which
56 will then be started by Ardour. For more control and options regarding
57 JACK, it is recommended that you start JACK before using Ardour, via a
58 JACK control application such as QJackCtl (sometimes called "Jack
59 Control"), JackPilot, etc.
63 <dd>Currently, the only option here is <kbd class="menu">JACK</kbd>. In the future, native
64 hardware access may be supported.</dd>
67 On Mac OS X this will typically be <kbd class="menu">CoreAudio</kbd>. On Linux usually
68 this will be either <kbd class="menu"><abbr title="Free Firewire Audio Driver fOr
69 linux">FFADO</abbr></kbd>
70 or <kbd class="menu"><abbr title="Advanced Linux Sound
71 Architecture">ALSA</abbr></kbd>, depending on whether or not you are
72 utilizing a firewire device. Advanced users on all platforms may also
73 use <kbd class="menu">NetJack</kbd> which provides network audio I/O.
76 <dd>The selector should show all availiable interfaces provided by the
77 driver above and which are capable of duplex operation.
79 If you are using an Intel Mac
80 running OS X and the builtin audio interface, you must
81 first <a href="setting-up-your-system/us
82 ing_more_than_one_audio_device/">merge its separate input and
83 output devices into a single "aggregate device"</a> before
84 Ardour will be able to use it.
89 The selector will allow you to select from any sample rate
90 supported by the device selected above it.
94 You can adjust the size of the buffer used by your audio interface
95 to allow for either lower latency, or lower CPU usage and higher
98 <dt>Input/Output Channels</dt>
100 Here you can specify the number of hardware channels to use. The
101 default is <kbd class="menu">all available channels</kbd>.</dd>
102 <dt>Hardware Input/Output Latency</dt>
103 <dd>Specify the hardware delay in samples for precise latency compensation.</dd>
106 This button guides you through a semi-automated process to obtain
107 precise hardware latency measurements for the above option.</dd>
110 Select the MIDI driver to use. On Mac OS X, this will be <kbd
111 class="menu">CoreMIDI</kbd>. On Linux, you can change between two legacy
112 ALSA drivers or the (preferred) new JACK+ALSA implementation.</dd>
