config SND_SEQUENCER
tristate "Sequencer support"
select SND_TIMER
select SND_SEQ_DEVICE
help
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.
if SND_SEQUENCER
config SND_SEQ_DUMMY
tristate "Sequencer dummy client"
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.
config SND_SEQUENCER_OSS
tristate "OSS Sequencer API"
depends on SND_OSSEMUL
select SND_SEQ_MIDI_EVENT
help
Say Y here to enable OSS sequencer emulation (both
/dev/sequencer and /dev/music interfaces).
Many programs still use the OSS API, so say Y.
To compile this driver as a module, choose M here: the module
will be called snd-seq-oss.
config SND_SEQ_HRTIMER_DEFAULT
bool "Use HR-timer as default sequencer timer"
depends on SND_HRTIMER

help
Say Y here to use the HR-timer backend as the default sequencer
timer.

default y if SND_SEQ_UMP_CLIENT
help
Say Y here to enable the support for handling UMP (Universal MIDI
Packet) events via ALSA sequencer infrastructure, which is an
essential feature for enabling MIDI 2.0 support.
It includes the automatic conversion of ALSA sequencer events
among legacy and UMP clients.
