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.

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 "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.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

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.
