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.

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.

Scrub deserves special mention. In an ideal world, scrub would be jog with sound.
|
|
|
|
|
However, Ardour does not have that functionallity 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.
