How do you stop the input/selected note from outputting in the step sequencer?

To stop the input or selected note from outputting in the step sequencer, turning off the MIDI out button is the appropriate action. The MIDI out function is responsible for sending MIDI data to any connected devices or virtual instruments. When you click the MIDI out button off, you effectively stop the notes from being transmitted, allowing you to control what you hear during your sequencing process.

This action is particularly useful during the editing phases, where one might want to work on a sequence without it actively triggering sounds or affecting other components of the project. Since MIDI data is not being sent out, you can focus on adjusting notes and settings without the distraction of audio feedback.

The other options involve different functionalities that do not directly control the output of notes from the step sequencer. For instance, pressing the stop button in the transport controls halts playback but does not alter the MIDI output settings. Toggling the output option in the MIDI settings menu might adjust how MIDI data is routed but does not specifically prevent it from outputting. Similarly, disabling the input monitoring option in preferences affects how input signals are heard during recording rather than controlling output in the sequencer.
