Input filtering

SONAR lets you filter out specific types of MIDI messages or filter the MIDI input stream channel by channel. Any MIDI information that is filtered out is neither recorded nor echoed to any other MIDI devices.

You can use the message type filter to screen out resource-intensive MIDI messages like key and channel aftertouch. By default, SONAR records all types of events except these two.

You can use message-type filtering to record short System Exclusive (Sysx) messages in real-time. These will end up in the track as Sysx data events, which can hold System Exclusive messages up to 255 bytes. Leave the Buffers setting at 128 unless you experience data not being recorded. For more information about Sysx, see System exclusive data.

To filter event types

1.	Go to Edit > Preferences > MIDI - Playback and Recording.

2.	Check the message types you want recorded.

3.

Click OK.

From now on, SONAR records only the types of events you have chosen.
