====== Loopy Pro: MIDI Map AUv3 Parameters ======
When Loopy Pro was initially released, only AUv3 effect parameters were mappable. All AUv3 can now have their parameters mapped.

There are a couple of main ways to MIDI Map Audio Unit Effect parameters:
  * Adding bindings to MIDI Control that map MIDI events (like CCs or notes) to AUv3 parameers
  * Using MIDI Learn to map the AUv3 parameters

You can also control AUv3 parameters with Loopy Pro's widgets: sliders, buttons and XY Pads.

**To use the MIDI Learn system**, turn on MIDI Learn. Tap on the AU's icon in the mixer (or tap on its icon from the main view if it is visible). A window pops up that lets you select learnable actions: Enable/Disable Effect, Open Effect Interface, **Adjust Effect Parameter**, Select Effect Preset. Choose **Adjust Effect Preset** and then pick the parameter to map and either send the MIDI event to learn or manually assign the event that you want to use.

**To use the MIDI Control system**, choose MIDI Control from Loopy's main menu and Add a New Binding. A binding is a mapping of a MIDI event (such as note, CC or program change) to actions. The Loopy Pro actions that control AUv3 parameters are:
  * AUv3 Effects: Effect Actions-> Adjust Effect Parameter
  * AUv3 Instruments:  Audio Source Actions -> Adjust Audio Unit Parameter
  * AUv3 MIDI FX: MIDI Source Actions -> Adjust MIDI Unit Parameter

This video demonstrates how to add a binding for an AUv3 Effect parameter using MIDI Control:

==== Using Widgets ====
You can also use widgets to control the parameters of your AUv3s

  * Add a widget to your layout
  * Tap on the pencil icon to edit the widget
  * Tap on a + sign for the event that you want to add the action to
  * Add the action from the Effect Actions list
