ASEQDUMP(1)                 General Commands Manual                 ASEQDUMP(1)

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  val-
              ues,  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.
