This new packet format supports a total of 256 MIDI channels, organized in 16 groups of 16 channels; each group can carry either a MIDI 1.0 Protocol stream or new MIDI 2.0 Protocol stream, and can also include system messages, system exclusive data, and timestamps for precise rendering of several simultaneous notes. To simplify initial adoption, existing products are explicitly allowed to only implement MIDI 1.0 messages. The Universal MIDI Packet is intended for high-speed transport such as USB and Ethernet and is not supported on the existing 5-pin DIN connections.<sup id="cite_ref-MIDI20-2019_169-2" class="reference"><a href="#cite_note-MIDI20-2019-169"><span class="cite-bracket">&#91;</span>159<span class="cite-bracket">&#93;</span></a></sup> System Real-Time and System Common messages are the same as defined in MIDI 1.0.<sup id="cite_ref-MIDI20-2019_169-3" class="reference"><a href="#cite_note-MIDI20-2019-169"><span class="cite-bracket">&#91;</span>159<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="New_protocol">New protocol</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MIDI&amp;action=edit&amp;section=60" title="Edit section: New protocol"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>As of January 2019, the draft specification of the new protocol supports all core messages that also exist in MIDI 1.0, but extends their precision and resolution; it also defines many new high-precision controller messages.<sup id="cite_ref-MIDI20-2019_169-4" class="reference"><a href="#cite_note-MIDI20-2019-169"><span class="cite-bracket">&#91;</span>159<span class="cite-bracket">&#93;</span></a></sup> The specification defines default translation rules to convert between MIDI 2.0 Channel Voice and MIDI 1.0 Channel Voice messages that use different data resolution, as well as map 256 MIDI 2.0 streams to 16 MIDI 1.0 streams.<sup id="cite_ref-ADC19_MIDI2_172-0" class="reference"><a href="#cite_note-ADC19_MIDI2-172"><span class="cite-bracket">&#91;</span>162<span class="cite-bracket">&#93;</span></a></sup><sup id="cite_ref-ADC19-VST3_173-0" class="reference"><a href="#cite_note-ADC19-VST3-173"><span class="cite-bracket">&#91;</span>163<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Data_transfer_formats">Data transfer formats</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MIDI&amp;action=edit&amp;section=61" title="Edit section: Data transfer formats"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>System Exclusive 8 messages use a new 8-bit data format, based on Universal System Exclusive messages.
