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.

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.

If you disable this option, the ALSA's OSS PCM API will not

help
|

Say Y here to enable RTC timer support for ALSA. ALSA uses

the RTC timer as a precise timing source and maps the RTC
|
|
timer to ALSA's timer interface. The ALSA sequencer code also
|
|
can use this timing source.
|
|

To compile this driver as a module, choose M here: the module

Note that this option is exclusive with the new RTC drivers

(CONFIG_RTC_CLASS) since this requires the old API.

|

Say Y here to use the RTC timer as the default sequencer
|
|
timer. This is strongly recommended because it ensures
|
|
precise MIDI timing even when the system timer runs at less
|
|
than 1000 Hz.
|
|
|
|
If in doubt, say Y.

config SND_DYNAMIC_MINORS

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

If you are unsure about this, say N here.
