Audio Performance
Within the Lexicon Studio def.all file included in your install, 16 channels have been set
up as a default number of channels. This can be increased or decreased depending
upon the job.
The Memory per Channel setting recommended by Lexicon is 768 kB per channel.
The Disk Block Buffer Size setting recommended by Lexicon is 128 kB
These settings are a good starting point for all systems. Systems with very fast CPUs, such
as 333 mHz machines may find increased performance by decreasing the Disk Block Buffer
size, and in some cases the Memory per Channel as well. Experiment with your system to
determine your optimum settings for your particular machine. Additionally, please consult
our Website for new information regarding all machines, setups, and optimizations.
MIDI Sync Reference
Use the Audio Clock setting in sessions with MIDI information to synchronize MIDI with
recorded digital audio. This may also yield superior results in digital I/O situations.
Use the Timecode setting when using timecode in a session (this is more current
information than in your printed manual).
Audio I/O
ASIO Control Panel: This button will open the Core-32 Control Panel. See your manual for
more details on the features controlled by these panels.
Sample Rate: This selects the sample rate of the current job you have open. If your playback
seems to be monitoring at incorrect pitch, the sampling frequency may be set incorrectly. A
48 kHz file played back at 44.1 kHz will sound slow and at a lower pitch, while a 44.1 kHz
file played back at 48 kHz will sound faster and higher in pitch.
Audio Clock Source: For analog-only recordings, this should be set to internal. You may
also use the analog inputs while locked to an external clock source, but be observant that
you know where your audio clock is coming from, and that you are properly locked to it.
When recording from a digital source, you
for both S/PDIF and ADAT. The playback device is usually the clock master, and the record
device is usually the clock slave.
Monitoring
Use Tape Type monitoring when transferring audio from previously recorded sources.
Use Global Disable along with the Punch Record feature within Lexicon Studio when
live performances are being recorded. This feature will allow you to monitor with NO
DELAY, and eliminates the requirement of an external mixer for zero latency recording.
For larger sessions with many instruments and microphones, you may still benefit from
the use of an external mixer to provide headphone feeds to your musicians.
