Description:

ASeqView is an ALSA sequencer user-client which works as event viewer.
It visualizes received events, e.g. note-on/off, controls, pitch wheels,
using bar graphs, as often seen in many sequencer programs. Using this
viewer, even a simple command line sequencer like pmidi or playmidi1
becomes a cool one with graphical interface :-)

Another feature of ASeqView is redirection of events. ASeqView can
output the received events to subscription ports with some modification
like channel mute or pitch change. Since this works as a real-time
filter client, such modifications can be applied also in real-time
without complexity.
