# SPDX-License-Identifier: GPL-2.0-only 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 default y help Say Y here to use the HR-timer backend as the default sequencer timer. config SND_SEQ_MIDI_EVENT tristate config SND_SEQ_MIDI def_tristate SND_RAWMIDI select SND_SEQ_MIDI_EVENT config SND_SEQ_MIDI_EMUL tristate config SND_SEQ_VIRMIDI tristate config SND_SEQ_UMP bool "Support for UMP events" 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. config SND_SEQ_UMP_CLIENT tristate def_tristate SND_UMP endif # SND_SEQUENCER
