REAPER's sends and receives can be used with audio items, MIDI items, or both. You have already been introduced to this topic (Chapter 5), and it is covered in more depth in Chapter 17. Meanwhile, note that the button indicated on the right can be used to ensure that a send's fader controls are used to control the MIDI data. With this button enabled, CC messages CC07 for Volume (127, max) and CC10 Pan (64, center) are sent on the selected channels (by default, all channels). If there are any MIDI items (even empty ones) on the sending track, they are sent when transport starts or stops, or play position changes. However be aware that not all synths and plug-ins recognize this feature.
