Chapter 1 Using Logic 15
Using the Mouse for In/Decrementing
Nearly all parameter values that can be set using the mouse as a slider (and even some
of the pull-down menu parameters) may also be increased or decreased in single units
by clicking on the top or bottom half of the value, while holding down Control.
Numerical Input
Double-clicking on a numerical parameter value opens an input field. The existing
value is highlighted, and ready to be overwritten by a new entry. You can also use the
mouse to make a partial selection in an input field, so that only the highlighted part is
overwritten. As long as the input field is open, the computer keyboard may only be
used for data entry, and may not be used for key commands (with the exception of the
main menu functions).
Arithmetical Operations
You can enter numbers at any time by typing in an arithmetical operation: “
+
2” or “
−
5”,
for example, which changes the current value by/to that amount.
ASCII Code
You can also input numbers as ASCII code: just place a ` or " in front of the selected
key, and the ASCII code will be input as a number. As an example:
• "! results in a value of 33
• "a results in a value of 97
This function is particularly useful for entering text in SysEx strings.
Cancel Numerical Input
Direct numerical input can be canceled by entering no text at all and pressing Enter or
Return.
