Limiting the Range of a Knob or Slider
The MIDI protocol allows for a maximum range of transmitted values between 0 and 127. The effective range of values
transmitted by Knobs and Sliders can be limited by entering values other than 0 and 127 (default) for the Data 2 and
Data 3 parameters.
transmitted by Knobs and Sliders can be limited by entering values other than 0 and 127 (default) for the Data 2 and
Data 3 parameters.
For example with the Data 2 parameter set to 38 and Data 3 set to 93, if a knob is set fully counter-clockwise, the
lowest value it transmits is 38. If the knob is turned fully clockwise, the highest value it transmits is 93. This can be
useful in a variety of scenarios, for example to keep a knob within the
lowest value it transmits is 38. If the knob is turned fully clockwise, the highest value it transmits is 93. This can be
useful in a variety of scenarios, for example to keep a knob within the
"sweet spot" of a synthesizer parameter (for
example, filter cutoff), or to quickly recall a specific minimum or maximum volume setting for a track.
The following example configures a knob or slider to operate within a limited range (38 to 93):
1. Select a a Knob or Slider as described earlier in this guide
2.
2.
Press the Advanced button
3.
Press the Control Assign key
4.
Type 7 using the number keys. This assigns MIDI CC number 7 (Volume) to the knob or slider. See Appendix A
5.
Press the Enter key
6.
Press the Advanced button
7.
Press the Data 2 key
8.
Type 38 using the number keys
9.
Press the Enter key
10. Press the Advanced button
11. Press the Data 3 key
12. Type 93 using the number keys
13. Press the Enter key
11. Press the Data 3 key
12. Type 93 using the number keys
13. Press the Enter key
NOTE: The operation of knobs and sliders can be reversed, even if the range of operation is limited. This is achieved
by entering a higher value for the Data 2 parameter and a lower value for the Data 3 parameter.
by entering a higher value for the Data 2 parameter and a lower value for the Data 3 parameter.
