+aseqview (ALSA sequencer event viewer)
+
+ASeqView is an ALSA sequencer user-client which works as an 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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
