Core Audio
and ASIO
Drivers
The Scratch Live installer includes drivers
that allow you to use your Rane Sixty-Two
with other audio applications. The Core
Audio (Mac) and ASIO (PC) drivers can be
installed when you install Scratch Live.
See the instructions in “Installing Scratch
Live” on page 12.
Once installed, you will have the option
to use the Sixty-Two with 3rd party DAWs
using ASIO or Core Audio interfaces.
NOTE: These drivers only work with audio
applications that are compatible with
these audio standards.
ASIO (Windows)
The Sixty-Two comes with a low-latency
ASIO device driver to interface with
software applications other than Scratch
Live on Windows operating systems.
Multi-client ASIO allows different audio
software applications to simultaneously
stream audio to and from the Sixty-Two.
If the same playback channel is selected
in more than one application, the driver
mixes the audio from the applications
before streaming it to the device.
The driver Control Panel may be
launched from the Windows Control
Panel. Select Start > Control Panel > Rane
Sixty-Two.
Core Audio (Macintosh)
The Sixty-Two uses a low-latency Core
Audio device driver to interface with
software applications other than Scratch
Live on Macintosh operating systems.
Core Audio allows different audio software
applications to simultaneously stream
audio to and from the Sixty-Two.
To launch the Sixty-Two driver Control
Panel, open the System Preferences
window. Locate the Sixty-Two in the
“Other” section and click the Sixty-Two
icon.
Driver Control Panel
The control Panel consists of four pages:
Preferences, Program Inputs 1-2, Effects
and MIDI. To move between the four
pages, click the
icon in the upper
left-hand corner of the control panel.
Preferences page controls:
•
USB-6 (11-12) Record source
: Two
radio buttons select the Main Mix or
Mic.
•
USB-3 (5-6) Filter Resonance
: Slider
adjusts the resonance from Low to High
for the
AUx
Filter.
•
USB Port Status
: Indicates active USB
port(s).
•
Buffer Size
: The Buffer Size control
allows the USB driver buffer to be
increased or decreased. The Sixty-Two
drivers are designed to run at latencies
as low 8 milliseconds. However,
computer performance and available
resources (number of applications
running) may adversely affect the
computer’s ability to stream audio
reliably. If pops and clicks are heard in
the USB audio, try increasing the buffer
size to eliminate them. With ASIO, total
round-trip latency is equal to Buffer Size
plus device latency. With Core Audio,
total round-trip latency is equal to Buffer
Size plus software application buffer
latency, plus device latency. Device
latency is 2.26 ms.
•
Update Device Firmware
: This panel
indicates the firmware version currently
installed in the Sixty-Two. If the Sixty-
Two firmware installed on your computer
is newer than the firmware in your
Sixty-Two, the Update Device Firmware
panel is enabled. Pressing the Update
Firmware button updates the Sixty-Two
firmware to the newer version.
PGM Inputs 1-2 Page Controls:
There is one panel for each channel strip
on the mixer. Each PGM panel controls
these functions:
•
Analog Input Source
: The analog input
for each channel may be set for Line
level (CD) or Phono level (PH) using a
switch on the rear of the mixer. PH/CD 1
and PH/CD 2 are associated with PGM
1. PH/CD 3 and PH/CD 4 are associated
with PGM 2. The control panel shows
the input mode selected on the mixer for
each of the four inputs. The mode can
only be changed on the mixer.
•
Phono Sensitivity
: If Phono Input
is selected on the mixer, the Phono
Sensitivity adjustment appears in the
panel. Click the down-arrow to display
a list of 16 sensitivity settings between
2.5 mV and 10 mV in 0.5 mV steps. The
default is 5 mV. 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.
•
Filter Resonance
: Each channel of
the Sixty-Two has a Filter knob that
provides High- and Low-Pass filtering.
Filter resonance controls the “peak”
of the filter cutoff frequency. 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 to audio as the Filter is swept. The
default is 5 dB.
