33 -u,--ump=version
34 Sets the client MIDI version. 0 is for legacy mode, 1 is UMP
35 MIDI 1.0 mode, and 2 is UMP MIDI 2.0 mode.

45 numbers are 0-based in this mode. This is the default behavior.
46
47
48 -N,--normalized-view
49 Shows the normalized values to be aligned with MIDI 1.0. The
50 channel numbers and UMP group numbers are shown as 1-based val‐
51 ues, i.e. 1 is the lowest number. The velocity and data values
52 are normalized between 0 and 127. The values for MIDI 2.0 are
53 shown with two digits decimal points (from 0.00 to 127.00). The
54 pitch wheel is normalized between -8192 to 8192, too.
55
56
57 -P,--percent-view
58 Shows the values in percentage. The channel numbers and UMP
59 group numbers are shown as 1-based values in this mode, too.
60 The velocity and data values are normalized between 0 and 100%,
61 shown with two digits decimal points. The pitch wheel is nor‐
62 malized between -100% to 100%, too.
63
64
65 -p,--port=client:port,...
66 Sets the sequencer port(s) from which events are received.
67
68 A client can be specified by its number, its name, or a prefix
69 of its name. A port is specified by its number; for port 0 of a
70 client, the ":0" part of the port specification can be omitted.
