A few other files were touched as well as they were referred to by files in the MIDI part, which lead to other connected things being pulled in. As this is only the first pass, there will be more necessary changes coming in the near future. Also, the lowest two levels of structure were mistakenly removed from the build system; these have been added back as they are necessary to keep the structure of the manual sane.

The <code>/jog</code> command will have a different affect depending
|
|
on which jog mode is selected. The jog system has two commands and
|
|
gives feedback of the mode chosen.

<table class="dl">
|
|
<tr><th><kbd class="osc">/jog <em>delta</em></kbd></th>
|
|
<td>Where <em>delta</em> is a float indicating the amount and direction.</td></tr>
|
|
<tr><th><kbd class="osc">/jog/mode <em>mode</em></kbd></th>
|
|
<td>Where <em>mode</em> is an int from 0 to 7 indicating the mode</td></tr>

Feedback is as below

The jog mode may be set using a slider with 0 to 7 limits, a group of switches
|
|
or radio buttons. What works in any situation will depend on the controller.

<h2 id="scrub">Scrub</h2>

Scrub deserves special mention. In an ideal world, scrub would be jog with sound.
|
|
However, Ardour does not have that functionality yet. So scrub starts the transport
|
|
rolling at either 50% or 100% depending on how fast the jog wheel is turned. The
|
|
position of the last tick is always saved and if no more ticks are received, the
|
|
transport is located there when stopped at time out. If the jog wheel gives a value
|
|
of 0 when released the transport stops at the location the value 0 is sent.
