12.4.13. md5sum
Open a file, a directory or just launch it from the plugin menu to create an md5sum of
the file, the directory’s contents or the whole filesystem. If the file’s extension is
.md5
or
.md5sum
, it will check the md5 sums in the file instead. If the file’s extension is .md5list
it will compute md5 sums for all the files listed.
12.4.14. Metronome
This plugin can be used as a metronome to keep time during music practice. It supports
two modes of operation, depending on it being started from the plugin menu or as viewer
for tempomap (
.tempo
) files.
The sound is a piercing square wave that can be heard well also through loud music
from a band. In addition, the display also indicates the beats while playing so that you
can discreetly place the device in your sight for checking the tempo instead of wearing
headphones at a concert.
Simple Interactive Mode
This is the mode of operation that is active when starting the plugin directly from the
menu. It offers a uniform metronome sound at a constant tempo. You can adjust the
tempo through the interface or by tapping it out on the appropriate button.

Programmed Track Mode
When starting the plugin as a viewer for tempomap files (ending in
.tempo
), it starts
in the track mode that offers playback of a preprogrammed metronome track consisting
out of multiple parts, each with possibly different properties.
In contrast to the simple mode, there exists the notion of meter and bars, along with
emphasis on certain beats. Parts can have these properties:
•
finite or infinite duration in bars (navigation only jumps to the beginning of infinite
parts),
•
differing meters (4/4, 3/4, 6/8, etc., default 4/4),
