Additional
Setup
This section covers general preferences
and adjustments you can make to improve
the performance of Scratch Live. From the
top of the main screen, click on
SETUP
to
get to this area.
Hardware: General
USB Buffer Size (Latency)
Scratch Live processes audio in small
chunks. When smaller chunks are
used, the movement of the record is
translated into audio more often, which
results in a lower overall system latency.
However, this requires more processing
and therefore a higher CPU load, so
lower buffer size settings require a
more powerful computer to produce
uninterrupted audio. If you want tighter
control, try decreasing this setting. On
the other hand, if you experience audio
dropouts, you need to increase this
setting (or use a more powerful computer).
Updating Firmware
If a firmware update is available after
installing a new Scratch Live software
release, an
Update Firmware
button
appears in the Hardware screen. During
the firmware upgrade the Sixty-One will
not be usable.
Control Source
Select the Input you wish to use as
your control source for both PGM 1 and
PGM 2. Select 1 or 2 for PGM 1 and 3 or
4 for PGM 2.
Default control sources are Inputs 1 and
3. To reset the Channel Filters and Control
Sources of the Sixty-One to default
settings,
See “Factory Defaults” on
page 11
.
Allow MIDI Assign of Mixer
Controls
Check this box to allow the mixer controls
to be custom MIDI-mapped in Scratch
Live.
See “MIDI Mapping” on page 46
.
Recording Bit Depth
Choose to record in either
16-Bit
(CD
quality, smaller file size) or
24-Bit
(high
quality, larger file size).
See ““Recording”
on page 34.
Input Select Status
The input levels currently set by the
switches on the Sixty-One are displayed
for each input. To change the input level
setting, use the switches on the Sixty-
One. Choose
PH
for Phono and
cD
for Line
level.
When Phono is selected, the
Phono
Sensitivity
setting is also displayed. Set
the Phono Sensitivity to the same level
of your cartridge (see your cartridge
documentation for the correct value).
Another method is to match the level of a
CD on another input.
The default setting is 5mV.
See
“Factory Defaults” on page 11.
Hardware: Effects
Channel Filters
Adjust the Resonance for the PGM 1 and
PGM 2 Filters. Filter resonance controls
how “peaky” the filter cutoff frequency
gain is. The Low setting provides the
smoothest Filter without adding gain. The
High setting adds accent to frequencies
near the Filter cutoff point by adding
about 12 dB of gain. Adding gain in a
narrow region around the cutoff frequency
adds a “zip” effect as the Filter is swept.
See “Filter” on page 8
.
With a resonance range of 0 to 12 dB,
the default setting is 5 dB. To reset the
Control Sources, Phono Sensitivity and
Channel Filters of the Sixty-One to default
settings,
See “Factory Defaults” on
page 11
.
NOTE: Settings are saved in the mixer.
Software is updated with the mixer’s
settings.
