+ (description "mloop is a live MIDI looping system, using jack-midi.
+Loops are recorded, optionally with beat quantization, and can then be played
+back, either once or looping. A 'note cache' system is implemented to
+remember which notes are pressed and their velocities. This allows for a loop
+to start off with the currently pressed notes, making seamless loops much
+easier to perform. Features include:
+
+@itemize
+@item Quantisation; end a loop on a beat exactly.
+@item Delayed recording; wait for a MIDI event before starting a loop record.
+@item Adjust tempo; Playback speed of loops can be adjusted on the fly.
+@end itemize\n")
