Description

The alsamidisrc element is an element that fetches ALSA MIDI sequencer events and makes them available to elements understanding audio/x-midi-events in their sink pads.

It can be used to generate notes from a MIDI input device.

Example launch line

1
gst-launch -v alsamidisrc ports=129:0 ! fluiddec ! audioconvert ! autoaudiosink
This pipeline will listen for events from the sequencer device at port 129:0, and generate notes using the fluiddec element.
