The Check Buffers and Sync dialog
This dialog is opened by clicking the “Check Buffers and Sync” button in the Ad-
vanced Options dialog. In a situation when you have to manually change your
Buffer and/or Sync Reference settings, it helps you check if your settings are OK.
This is how to use it:
1. In the Port list, select the Port you want to test.
The function will perform a test that determines both whether MIDI to Audio
synchronization will work, and whether audio playback/recording will work
without dropouts. If you are specifically interested in testing synchronization,
you should probably select the Port currently used as Sync Reference (see
page 374).
2. Click the “Check Buffers and Sync” button.
The dialog opens. At the top of the dialog, the name of the selected Port is dis-
played.
3. Select a method for Sync Reference.
As described above, Sample Position is the preferred choice if your audio
card supports it.
4. Make settings for Audio Buffers and Buffer Size.
These settings are used for the test only. You can apply them as “real” settings
by clicking the button “Apply Buffer Settings”. This makes it easy to try out
different settings, and apply them after the test has indicated that they should
work.
5. Set a test period with the slider.
You can set a test period ranging from 1 second to 5 minutes. The longer the
test period, the more certain you can be that your settings will work.
