Project Settings and Preferences
 Use Variable Bit Rate Encoding (VBR): Variable Bit Rate encoding compresses simpler
passages more heavily than harmonically rich passages, generally resulting in better
quality MP3s. Unfortunately, not all MP3 players can accurately decode VBR-encoded
MP3s, which is why this option is off by default. If you know that the audience for
your MP3 can decode VBR-encoded MP3s, you can switch this option on.
 Quality: Keep this set to Highest whenever possible. Reducing the quality will
accelerate the conversion process, but at the expense of audio quality. This option is
only accessible when the VBR checkbox is turned on.
 Use Best Encoding: Again, like the Quality parameter, if you uncheck this option, you
will gain encoding speed at the price of audio quality. This should always be left on,
unless conversion time is an issue.
 Filter Frequencies Below 10 Hz: When this option is checked, frequencies below 10 Hz
(which are usually not reproduced by speakers, and are not audible to human ears at
any rate) are removed, leaving slightly more data bandwidth for the frequencies
which humans can hear, resulting in an improvement in perceived quality. Only
uncheck this option if you’re experimenting with subsonic test tones, or exporting
MP3s for whales.
 Stereo Mode: You can choose between Joint Stereo or Normal Stereo in this pop-up
menu. Depending on the original file, these settings may (or may not) offer any
audible difference. Experiment with both settings to determine your preference.
Reset Preferences
Activate the appropriate checkboxes for “Control 64 off (Sustain)”, “Control 1
(Modulation) to zero”, and “Pitch Bend to center position” to send reset messages of the
specified type to all active instrument channels.
This can be useful if you are encountering hung notes, or are finding that controller
settings are incorrect when in Cycle mode (or when returning to the beginning of a
section or the project start point).
