Fader Functions: Range, Val as
Range
The range parameter contains two numbers—the left one sets the lowest possible
fader value, and the right one sets the highest. Note that these limits can be exceeded
by MIDI remote control. When the fader style is a button, the range determines the in
and out position values of the button.
For text style faders, the first name always corresponds to the low end of the range,
and subsequent names correspond to incremental range values, up to the top range.
The number of names that can be entered into the window is limited by the range.
Val as
This parameter determines the way that numerical values are displayed by the fader:
Num
The fader value is displayed directly as a number (0 to 127).
Pan
Fader value 64 is displayed as “0”; smaller values appear as negative numbers and larger
values as positive numbers (
−
64 to 63).
Hz, Oct, dB, ms
These display formats are tailored to various DSP functions.
bpm
An offset of 50 is added to the fader value. This displays the correct tempo settings for
the special tempo control fader.
If none of the above formats is suitable, consider using a text style fader, and entering
the desired display values as text. Examples include percentages, note names and
program names.
Fader Functions: Filter
This parameter provides various filter options for MIDI events:
off
All incoming MIDI events are allowed to pass through. All events that match the input
definition are converted, in accordance with the output definition.
Other
All MIDI events that do not correspond to the input definition are filtered. All events
that match the input definition are converted in accordance with the output definition,
and allowed to pass through.
Match
All MIDI events that match the input definition are filtered, all others are allowed to
pass.
