USB Audio
In addition to the stereo line outputs, Kyra streams each of
its 8 stereo Parts over USB as 'virtual' connections to the
host DAW (Digital Audio Workstation). The Output Mixer
is not used for USB audio (but remains functional for the
line outputs) and each Part is streamed independently
directly from its Part without any further mixing or pro-
cessing.
Any mixing required can be done in your DAW. Like the
line outputs, Kyra's USB audio runs at the native 96kHz
audio format to ensure the highest possible quality audio
is available to your DAW. You can also select 48 kHz audio
by configuring your DAW for 48 kHz operation. Note that
the 48kHz downsampling only affects USB audio. Kyra's
internal processing and the line outputs always run at 96
kHz. At either sample rate, the bit depth of the audio is 24
bits.
You can of course resample the audio in your DAW as part
of the final mixdown of your song, e.g. if you are mixing
down for mastering a CD at 44.1 kHz. Note that Kyra can't
stream at 44.1 kHz, only 48 kHz and 96 kHz are available.
If you are mastering for CD, run your project at 48 kHz or
better still, 96kHz and resample to 44.1 kHz when you
produce your final master.
g
We recommend you stream Kyra’s USB audio at
96kHz 24 bit and only resample when you produce
your final mixdown for mastering. Consider 48kHz
only if your DAW is not fast enough to accommo-
date 96kHz audio.
As Kyra has a USB 2.0 port with a capacity of 480
Mbits/sec, there are no inherent constraints on audio
streaming as was often the case on synthesizers using the
older USB 1.x specifications (referred to as 'low speed' and
'full speed'). Check that your computer has the specifica-
tions necessary to support the high data rates involved.
Note that Kyra does not support legacy USB 1.1 (for audio
or MIDI); a USB 2.0 or above compatible USB port is requi-
red.
r
Kyra will not connect to a low speed or full speed
USB 1.x port.
Remember that the
Master Volume
control does not affect
USB audio. Use Part Levels or controls on your DAW to do
any necessary mixing and levels management.
You can check the sample rate Kyra is running at in the
System Configuration pages.
