			Another method is to set up a dummy fader or knob that does nothing and to target it with the trigger widget action as shown in the picture. When using this method, the trigger widget action must come first.

	If you prefer the look of a slider or non-stepped dial, you can use the stepped dial to send the actual MIDI and a slider or dial whose action is Trigger Widget. You can hide the dial on another page if you would like.		=== Setup For Two Way Communication ===
			The setup discussed in the ''Basic Setup'' above is for one-way communication where you are sending MIDI from Loopy Pro and don't need the widget to be updated from the external device. If the widget is going to receive MIDI from an external device as well as send MIDI back to the device, the setup needs to be a little different.

			Let's say that you have a fader on your MIDI hardware that sends CC09 to Loopy Pro when you move it. Sometimes you want to use that hardware knob, and sometimes want to use an on-screen slider or dial in Loopy Pro. In this case, we will MIDI Learn the MIDI CC sent from the external device without setting up any Send MIDI action in Loopy Pro. Loopy Pro's automatic MIDI Feedback to the controller will take care of sending MIDI back to the device when we adjust the onscreen control.

			# '''Enable Feedback'''. Make sure that Feedback Enabled is turned on for the external device in Loopy Pro's Control Settings.
			# '''Create a 128 step dial'''. Create a Stepped Dial that has 128 steps (the number of MIDI values that can be sent). A quick way to create such a stepped dial is to create a new dial. Tap Select Item +. Choose Send MIDI as the action. Tap on PC. You don't have to select a target. Tap Back. You know have a 128 step dial. Delete the Send MIDI action by swiping left. You will now have a 128 step dial that does nothing.
			# '''Disable State Feedback for the dial'''. Tap on the dial's gear wheel and set State Feedback to Disabled.
			# '''MIDI Learn'''. Turn on MIDI Learn and tap on the stepped dial. Send MIDI from your external device to Loopy and turn off MIDI Learn.

			If you prefer to interact with a slider or non-stepped dial, the steps are ever so slightly different. Perform steps 1-3. Then create the slider or non-stepped dial. Set the slider or non-stepped dial's Value Change action to be Trigger Widget and select the stepped dial you created in step 2. Now, MIDI Learn the slider/non-stepped dial instead of the stepped dial.

			That may all sound complicated, but you will find that it is very quick to set up. Once you have set up one control, you can copy/paste to create additional controls.
