+              Enqueues the message to be sent to the corresponding MIDI port.  The underlying implementation will (if necessary) coerce each member of the sequence to an unsigned 8-bit integer.  The use of sequence rather than a UInt8Array enables developers to use the convenience of <code>output.send( [ 0x90, 0x45, 0x7f ] );</code> rather than having to create a UInt8Array, e.g. <code>output.send( new UInt8Array( [ 0x90, 0x45, 0x7f ] ) );</code> - while still enabling use of UInt8Arrays for efficiency in large MIDI data scenarios (e.g. reading Standard MIDI Files and sending sysex messages).
