Mackie Control V-Pots in Logic Pro
The V-Pot is a rotary encoder, with an integrated button (accessed by pressing down on the top of the encoder). You can use the V-Pot to adjust the channel’s send level and pan/balance (in Channel view) or to adjust effect or instrument plug-in parameters. The V-Pot can also be used to scroll through and choose items such as plug-ins, software instruments, and more from menus, and to determine send destinations. The faster you turn the V-Pot, the quicker it changes values, scrolls through menus, and so on.
The top of each V-Pot has an integrated push button, which typically sets a default parameter value (if a parameter has more than two possible values) or switches between two parameter values (on/off). The button can also be used to activate a function you have selected with the V-Pot. For example, you can turn the V-Pot to scroll through a list of effect plug-ins for one of the channel Insert slots. Once the effect you want is displayed in the main LCD, press the top of the V-Pot to select and insert the effect, and open the plug-in window. The button is also sometimes used to switch to a special assignment mode.
When a value or name (such as a plug-in) has been preselected, but not confirmed or inserted, the value (or name) flashes on the main LCD until you press the V-Pot button.
The current value of the parameter you are adjusting with the V-Pot is displayed on the main LCD (depending on the Name/Value setting) and is also indicated by the ring of LEDs encircling the V-Pot. The way that parameter values are displayed on the LED ring varies depending on the type of parameter being displayed.
Hold down the CMD/ALT button to set V-Pots to high-resolution (fine) mode, for parameters where this mode applies.
Hold down the OPTION button and turn a V-Pot to switch between the minimum, default, and maximum values for the parameter.
