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.

tristate "Sequencer dummy client"
|
|
depends on SND_SEQUENCER
|
|
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.

To enable OSS mixer API emulation (/dev/mixer*), say Y here

Many programs still use the OSS API, so say Y.

select SND_TIMER

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.

|
|
help
|
|
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.

Say Y here to enable verbose log messages. These messages

You don't need this unless you're debugging ALSA.
