NAME

       aseqdump - show the events received at an ALSA sequencer port

SYNOPSIS

       aseqdump [-p client:port,...]

DESCRIPTION

       aseqdump is a command-line utility that prints the sequencer events it receives as text.

       To stop receiving, press Ctrl+C.

OPTIONS

       -h,--help
              Prints a list of options.

       -V,--version
              Prints the current version.

       -l,--list
              Prints a list of possible input ports.

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

       -r,--raw
              Suppress the automatic conversion of events among UMP and legacy clients.

       -R,--raw-view
              Shows the raw values as is.  The channel numbers and UMP group numbers are  0-based
              in this mode.  This is the default behavior.

       -N,--normalized-view
              Shows  the  normalized values to be aligned with MIDI 1.0.  The channel numbers and
              UMP group numbers are shown as 1-based values, i.e. 1 is the  lowest  number.   The
              velocity and data values are normalized between 0 and 127.  The values for MIDI 2.0
              are shown with two digits decimal points (from 0.00 to 127.00).  The pitch wheel is
              normalized between -8192 to 8192, too.

       -P,--percent-view
              Shows  the  values  in  percentage.   The channel numbers and UMP group numbers are
              shown as 1-based values in this mode,  too.   The  velocity  and  data  values  are
              normalized  between  0  and  100%, shown with two digits decimal points.  The pitch
              wheel is normalized between -100% to 100%, too.

       -p,--port=client:port,...
              Sets the sequencer port(s) from which events are received.

              A client can be specified by its number, its name, or a prefix of its name.  A port
              is  specified  by  its  number;  for  port 0 of a client, the ":0" part of the port
              specification can be omitted.
