Hello! I wonder if it's possible to set up hardware MIDI playing in Linux using MPU-401 in Pegasos? I'd like to play MIDI files but unfortunately Pegasos is not fast enough to run Timidity.

I ran timidity++ on a 600MHz iBook. Without much CPU usage and without skips.

But I didn't got it managed to run timidity++ on the Pegasos. The new version seems to have endianess-problems. We are aware of the problem in the Gentoo-Development group and probably we can solve it.

On my Debian Timidity++ runs perfectly. Except CPU usage, of course. Three samples together + reverberation - it's enough for it...
The fact that your 600 mHz ibook ran it without problems gives me bad thoughts about Pegasos hardware design in general...

timidity++ 2.13.2 together with eawpatches 12-r4 is working on my Gentoo/Pegasos system. I use it for OpenTTD.

Tried that now on my Pegasos. I must say, the sound is so scary, as it uses 100% CPU power, just to play a simple midi file.

Did you changed something special?

Perhaps an intrepid developer could look at the source code for Timidity's
mixing routines and design a vectorised AltiVec alternative.

Audio is always an easy place to start - add one waveform to another, run
an FFT over it, these are the most commonly vectorisable routines you
could imagine. With a 16bit integer sample you could perform EIGHT
operations at once on a waveform.

Hmm, it sounds good here and is using approx 40% CPU. The only things I've done is to run timidity-update to select eawpatches and add /etc/init.d/timidity to the default runlevel.

I just installed timidity++ on my iBook. Same like on the Pegasos: 100% CPU usage and terrible sound.

Half a year ago (so last summer) I used timidity with a 42MB bank-file and kmid for playing some .kar (karaoke) files. Everything was fine. I can't remember if it was the 2.11 or 2.12 release. At least it had a complete different config file...

There is a nice Gentoo Bug about that problem with some more explanation: http://bugs.gentoo.org/show_bug.cgi?id=72332

Hi, all!
I have Timidity running on a Peg2 very good!
Additionally I use the timidity-plugin for xmms, so my xmms plays
nearly every sound format
Not really sure, but I think I compiled a snapshot of timidity...
I I find all needed files, I can make a (very basic) debian-package if needed...
