This is a method of creating a combined control for a coarse and fine voltage setting. It’s quite simple and uses the newer Vector controls. This is the finished control (Sorry that flashy looking knob in the centre is V1.5 only but the principle will work with the plain Vector Knob B in V1.4)
How it looks using Vector Knob B in V1.4
This is the structure below (Inside a container). We are just taking the Animation position of each vector control through a PatchMemory Float 3 to convert it to a DSP float value, this will later be converted to Voltage for DSP modules.
The PatchMem connected to the vector ring has its maximum value set to 1 so that we get a range of 0 to 1 for this control, and 0 to 10 for the Knob C. The two values are added together using an ED Add (Float) module, and converted to Volts for controlling DSP modules. This means we get a total range of 0 to 11 for the control (shades of Spinal Tap), so by setting the Knob C’s PatchMem to a maximum of 9, we go back to our usual default of 0 to 10 volts. All you need to do once its working is to create a panel view, size and line up the two controls then lock the container view and save as a prefab control.
This enables us to use the main inner knob as a coarse 0 to 10 control, and the outer ring as a fine 0 to 1 control (or any range you wish)
Changing the control ranges:
Changing the ranges for the inner and outer controls is as easy as setting the Max and Min values in the properties panel. This is set up for 0-to-1 for the outer ring, and 0-to-9 for the knob, giving an overall range of 0-to10 Volts out.
