What happens to data received at the MIDI In port? (Check all that apply. No partial credit.)

Data received at the MIDI In Port copied and echoed/re-directed the MIDI Thru Port. Data received at the MIDI In Port is directed to the host device internal synthesizer/sound engine.

When the receiving device is set to this MIDI Mode it responds to any imcoming MIDI messages on any/all MIDI channels 1-16. In this receive mode the receiving synthesizer will respond to any incoming messages (Note On, for example) no matter what MIDI channel is designated in the Status Byte. And the receiving synthesizer will sound as many notes at one time as it is capable of. This best describes __________.

Mode 1

When the receiving device is set to this MIDI Mode it responds to any imcoming MIDI messages on any/all MIDI channels 1-16.
