I guess the volume level is also set by the midi file itself (audibility improved a bit for me, with a different file). Still, the XOs are definitely not fog horns.

 

Agree - no fog horns. I recommend that m activities be run with headphones or an external audio system. Even a $1 set of headphones gives decent sound and allows stereo placement to be heard.

 

on a different tangent:

 

Is the following in beta, alpha, or a figment of someone's imagination still (concept stage):

Is anyone currently trying to develop realtime score visualization on the XO (Sugar)?  for any other GUI? (csound or midi)?

Greg Thompson's MIDI File Player is in the git repository: see http://dev.laptop.org/git/activities/ . It's a nice concept and works at least reasonably well on my XO. I installed it by doing the following:
1) Downloaded the .zip archive to my Windows computer.
2) Unzipped it to a USB drive.
3) Renamed the directory to MIDI-File-Player-Master.activity
4) Copied (with cp -r) the directory from the USB drive to the Activities directory of my XO - on my XO.
5) Reboot the XO and activate the activity (select the activity's star) in List view.
6) Click the activity's icon (it's called Player) on the Home screen. It's got a gear-like icon.
 
Obviously a great deal of work has gone into this activity. Perhaps it could be developed further.

If not, any pointers as to how to start such a development?

a.

Midi File Player works for me (to the extent that the XO can handle the CPU/RAM runtime load).  To launch from the command line ("sugar-launch <activityname>") I had to change the "name" parameter in ~/Activities/Player/activity/activity.info to match the activity name -- "Player", which I set up as a soft link pointing to the real directory with the activity bundle (~/Activities/<softlink>).

This is a great start. I assume the answer to my question about real-time visualized score (traditional notation) is "No" -- but this would be a great connecting piece, or even a _base_ for such visualization, since Greg Thompson has already done the grunt work with the csound-to-[visual sugar/python widgets] code.

thank you again!
