debian(etch)上にてrosegardenで内部音源を鳴らすには
You can also use Timidity to play to JACK with reasonably low latency, with some magic incantation like:
$ timidity -iA -Oj -B2,8
In my experience it takes rather more CPU power than fluidsynth for rather lower-quality output, though I'm sure these things vary a lot depending on how the soundfont is made.
jackを使う場合
まずjackdを以下で立ち上げ
$ /usr/bin/jackd -dalsa -dhw:0 -r44100 -p1024 -n2
次に別ターミナルで以下を立ち上げると見事にmidi演奏が可能になった。
$ timidity -iA -Oj -B2,8
