I'm not a musician but my nephew is. He plays guitar flamenco. Does the
metronome offer only binary rythmn or also
different rhythmn ? If not it could be another interesting option to
develop.
Tshaw !!

Hi,
I would like to start a new attempt at improving the metronome plugin
in Rockbox. There are two main points:
1. Support config files with programmed songs (sequences of patterns
with different meters / tempi). I guess it would make sense to use the
"tempo map" format of http://das.nasophon.de/klick/ for this.
2. Have an optical mode, flashing the display (or parts of it) instead
of or in addition to playing a sound.
An Editor for these tempo maps inside the plugin would be bonus, but
for starters I would consider the maps coming from elsewhere. My
platform is a Sansa Clip+. My questions for the seasoned Rockbox devs
are these:
1. Is there an API call to get a file selection dialog or should the
plugin instead register as handler/codec for tempo map files to be started
from the main "files" menu? Excuse me for not finding that answer
myself, I didn't find an obvious place where API/plugin design is
documented. Pointers welcome, of course.
2. Is using the display as flashing indicator LED feasible? I guess it
should be for the Clip+, as it's just a little grid of OLEDs. But the
question would be if it can be done quickly in a timely manner to serve
as metronome (thinking of switching the whole upper or lower half for
opposing tick/tock). Since there is no background illumination, it
should be rather power conservative to have all black pixels most of
the time, right? And regarding the speed/latency: I remember running
Doom on that display, so that should technically work;-)
I'm a seasoned C developer (some might recognize me for maintaining
mpg123 over the last 8 years) and am confident to get the job done for
giving Rockbox an awesome metronome, once I got the starting points. I
did read the source of the existing metronome plugin and would start
from there.
Alrighty then,
Thomas
