The MIOConsole3d Application

• Changing the host domain sample rate or USB port channel configuration will necessarily reset the
3d USB port. Generally this requires manually re-establishing the satellite audio software to the SCP
USB connection.
To minimize the possibility of unstable audio connections, it is recommended that you quit or tem-
porarily stop the audio connection of your satellite audio application, iOS or Android SCP clients
when reconfiguring the USB ports from MIOConsole3d.
• As with a 3d USB Host computer connection, the maximum sample rate available via each USB port
varies with the maximum channel count set for the USB connection. The number of input and output
channel can be set independently. The larger channel count of the two will determine the maximum
sample rate for the USB port.
• 4-12 channels works at all sample rates (44.1k - 192k)
• 4-24 channels works up to 2x rates (44.1k - 96k)
• 4-48 channels works only for 1x sample rates (44.1k - 48k)
This has the side effect that a USB port channel setting can lock out higher sample rates for the
domain. If you find yourself unable to set the domain sample rate higher than your current setting,
check the USB I/O channel count of each 3d box.
If your target sample rate is 4x (176.4 or 192kHz), make sure all USB ports are set to 12 I/O channels
or less.
If your target sample rate is 2x (88.2 or 96kHz), make sure all USB ports are set to 24 I/O channels
or less.
• Chances are, audio is not the only kind of data that will be bouncing around your computer‘s USB
buses. For instance, a great way to implode your USB audio connection is to connect a USB hard
drive on the same USB bus as you are playing and recording 48 channels of audio. Best practice is
always to keep critical audio transport on a physically isolated port, whether that be USB or Ethernet.
Gaming mice and keyboards, USB control surfaces and especially USB storage and video peripherals
can all have an impact on USB port audio stability. The degree of that impact will vary with each
individual computer configuration and software applications.
If you are getting tight on ports, a good-quality Thunderbolt dock can provide one or more isolated
USB ports, as well as HDMI and (more importantly) a Gigabit Ethernet port.
