- Say Y or M to enable MIDI sequencer and router support. This
- feature allows routing and enqueueing of MIDI events. Events
- can be processed at a given time.
- Many programs require this feature, so you should enable it
- unless you know what you're doing.

- help
- Say Y here to enable the dummy sequencer client. This client
- is a simple MIDI-through client: all normal input events are
- redirected to the output port immediately.
- You don't need this unless you want to connect many MIDI
- devices or applications together.
- To compile this driver as a module, choose M here: the module
- will be called snd-seq-dummy.
