4	select SND_TIMER
5	select SND_SEQ_DEVICE
6	help
7	  Say Y or M to enable MIDI sequencer and router support.  This
8	  feature allows routing and enqueueing of MIDI events.  Events
9	  can be processed at a given time.
10
11	  Many programs require this feature, so you should enable it
12	  unless you know what you're doing.

16config SND_SEQ_DUMMY
17	tristate "Sequencer dummy client"
18	help
19	  Say Y here to enable the dummy sequencer client.  This client
20	  is a simple MIDI-through client: all normal input events are
21	  redirected to the output port immediately.
22
23	  You don't need this unless you want to connect many MIDI
24	  devices or applications together.
25
26	  To compile this driver as a module, choose M here: the module
27	  will be called snd-seq-dummy.

31	depends on SND_OSSEMUL
32	select SND_SEQ_MIDI_EVENT
33	help
34	  Say Y here to enable OSS sequencer emulation (both
35	  /dev/sequencer and /dev/music interfaces).
36
37	  Many programs still use the OSS API, so say Y.
38
39	  To compile this driver as a module, choose M here: the module
40	  will be called snd-seq-oss.

48	  timer.

67	  Say Y here to enable the support for handling UMP (Universal MIDI
68	  Packet) events via ALSA sequencer infrastructure, which is an
69	  essential feature for enabling MIDI 2.0 support.
70	  It includes the automatic conversion of ALSA sequencer events
71	  among legacy and UMP clients.
