26 Say Y or M to enable MIDI sequencer and router support. This
27 feature allows routing and enqueueing of MIDI events. Events
28 can be processed at a given time.

37 Say Y here to enable the dummy sequencer client. This client
38 is a simple MIDI-through client: all normal input events are
39 redirected to the output port immediately.
40
41 You don't need this unless you want to connect many MIDI
42 devices or applications together.

141 Say Y here to use the RTC timer as the default sequencer
142 timer. This is strongly recommended because it ensures

151 If you say Y here, the minor numbers of ALSA device files in
152 /dev/snd/ are allocated dynamically. This allows you to have
153 more than 8 sound cards, but requires a dynamic device file
154 system like udev.
