MIDI Map AUv3 Parameters
There are a few ways to MIDI Map Audio Unit parameters:
- MIDI Learn to learn a parameter by moving its control in the AUv3 window
- MIDI Learn to learn a manually selected AUv3 parameter
- Manually adding bindings in Control Settings with the adjust parameter action.
You can also control AUv3 parameters with Loopy Pro's widgets: sliders, buttons and XY Pads.
MIDI Learn Using Discovery
The MIDI Learn system lets you move a control in an AUv3 window to discover the parameter you want to control.
- Open the AUv3 window
- Choose MIDI Learn
- Adjust the AUv3's control in its window
- Tap on the discovery knob that will know by pulsing to open the MIDI Learn panel for the parameter
- Send MIDI from your MIDI controller
MIDI Learning A Selected Parameter
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.
Manually Adding A Binding
To manually add a binding, choose Control Settings 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 the Control Settings (formerly MIDI Control) panel:
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
