Explained in a few words

GSequencer does audio output on GNU/Linux by ALSA. Avoid additional layers on ALSA like arts, esd or pulseaudio. The output to the soundcard is usually done by AgsPanel sink. Sounds are created by sequencers like AgsDrum, AgsMatrix and alike. Such sources can be bundled by AgsMixer and finally write to hardware by AgsPlayChannelRun recall.
