when pressed and then hold that state until one of several conditions is
met. The behaviors that occur as the result of a Press and Release 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 .
Note: If a switch is held down too long, it will change to Press and Hold opera-
tion. The length of time a switch may be held down is determined by the
Switch Press and Hold Threshold in the
D950desk.ini
file in the
D950System
folder.
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 specified period of time (typically 500 ms or so). The func-
tion 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 dura-
tion 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.
