| 23 | help |
| 24 | Say Y or M to enable MIDI sequencer and router support. This |
| 25 | feature allows routing and enqueueing of MIDI events. Events |
| 26 | can be processed at a given time. |
| 27 | |
| 28 | Many programs require this feature, so you should enable it |
| 29 | unless you know what you're doing. |

| 32 | tristate "Sequencer dummy client" |
| 33 | depends on SND_SEQUENCER |
| 34 | help |
| 35 | Say Y here to enable the dummy sequencer client. This client |
| 36 | is a simple MIDI-through client: all normal input events are |
| 37 | redirected to the output port immediately. |
| 38 | |
| 39 | You don't need this unless you want to connect many MIDI |
| 40 | devices or applications together. |

| 93 | help |
| 94 | Say Y here to enable RTC timer support for ALSA. ALSA uses |
| 95 | the RTC timer as a precise timing source and maps the RTC |
| 96 | timer to ALSA's timer interface. The ALSA sequencer code also |
| 97 | can use this timing source. |
