Fields
| Name | Value | Description |
|---|---|---|
| Unknown | -1 | Constant representing a device with an unknown default protocol. If Universal MIDI Packets (UMP) are needed, use MIDI-CI through MIDI 1.0. UMP is defined in "Universal MIDI Packet (UMP) Format and MIDI 2.0 Protocol" spec. MIDI-CI is defined in "MIDI Capability Inquiry (MIDI-CI)" spec.

| UmpUseMidiCi | 0 | Constant representing a default protocol with Universal MIDI Packets (UMP). UMP is defined in "Universal MIDI Packet (UMP) Format and MIDI 2.0 Protocol" spec. All UMP data should be a multiple of 4 bytes. Use UMP to negotiate with the device with MIDI-CI. MIDI-CI is defined in "MIDI Capability Inquiry (MIDI-CI)" spec. Call MidiManager.getDevicesForTransport with parameter MidiManager.TRANSPORT_UNIVERSAL_MIDI_PACKETS to get devices with this transport.

Remarks
These values represent the PROTOCOL_* constants of MidiDeviceInfo. The UMP values describe MIDI 1.0 or MIDI 2.0 messages carried in Universal MIDI Packets, with options for packet size and jitter reduction timestamps. UmpUseMidiCi selects protocol negotiation through MIDI Capability Inquiry (MIDI-CI).
Unknown indicates an unknown default protocol. It does not indicate an error; the device does not support Universal MIDI Packets by default.
See the Android default protocol reference.
