5.10.3.2 Press and Hold
Press and Hold is defined as using switches in a temporarily sustained manner.
To perform a Press and Hold operation, press a switch and hold it down for
a period of time before releasing it. Au senses how long the key is
down and its mode of operation changes if it is held down longer than a speci-
fied period of time (typically 500 ms or so). The function becomes similar to
touching a fader, keeping a finger on it, and then releasing it later.
Press and Hold operations perform the following functions:
• Switch Press:
- Toggles the switch state
- Produces a Touch event
• Switch Release:
- Punch-out
With Press and Hold operations, switches toggle to their alternate state when
pressed and then hold that state as long as the key is held down. When the
switch is released, it may or may not toggle depending on the state recorded
in the Read Mix Data at the time of release.
If Touch Record is engaged, the switch will punch-in as well as toggle its
alternate state when it is pressed. The switch will stay in that state and in
RECORD as long as the switch is held down. Upon release, the switch will
punch-out. It may or may not toggle states depending on the state recorded
in the Read Mix Data at the time of release. The change of state may Written
or Trimmed depending on the selected Control Mode.
The behaviors that occur as the result of a Press and Hold switch operation is
dependent on the switch’s Control Mode and whether Touch Record and/or
Touch Record is engaged. Refer to
chapter 5.10.2 , Switch Control Modes.
Press and Ho­ld Thresho­ld Whenever a work surface key is pressed, Au monitors the duration
the key is held down. If the time a key is held down is longer than the Switch
Press and Hold Threshold value, Press and Hold becomes active. If the hold
duration is less than the threshold time the Press and Release functions are
maintained.
