Soundcraft Ui12 and Multitrack Recording: Capabilities and Options

Before you start

The Ui12 is a digital mixer with built-in USB audio streaming, so the recording process runs locally through a computer connected by USB. Check that the mixer firmware is current and that you have a compatible USB cable. Windows and macOS computers are commonly used as the recording host, but you must verify support for your operating system version before relying on it.

Confirm that the Ui12 is recognized as an audio interface by the computer before opening recording software. If your computer does not show the mixer as an available audio device, the recording application cannot access its channels. You also need enough free storage space for the multitrack session and a recording application that can select the Ui12 as its input device.

Step-by-step instructions

Connect the Ui12 to the computer using a USB connection that is suitable for the ports on both devices. Avoid unpowered hubs if the mixer is not detected reliably.

• 1. Power on the Ui12 and let it finish starting up.
• 2. Connect the Ui12 USB port to a port on the recording computer.
• 3. Open the computer audio or sound settings and confirm that the Ui12 appears as an input and output device.
• 4. Open your recording application and create a project at a sample rate and bit depth supported by your setup.
• 5. Select the Ui12 as the audio input device in the application.
• 6. Create one track for each mixer channel you want to capture, or use the multitrack template if the application offers one.
• 7. Assign the correct Ui12 input channel to each track.
• 8. Set sensible recording levels on the mixer while sending a normal signal from the source.
• 9. Arm the tracks and record a short test before the full session.
• 10. Stop the test, play it back, and begin the real recording once routing and levels are acceptable.

Keep the USB cable stable during the session. Movement or an unreliable connection can interrupt the recording or make the mixer disappear from the application.

Check the output

After recording, play back each track individually and check that the expected source is present on the correct channel. Listen for clipping, dropouts, or digital noise. Watch the track meters during playback and compare them with the levels you saw while recording.

Multitrack recordings made through the USB interface are generally dry signals from the assigned inputs. Do not assume that channel processing such as EQ, compression, or effects is included in every routing option. Confirm whether your tracks are captured before or after the mixer processing by checking the routing choices available in your firmware version.

Common problems and next steps

If the computer does not see the Ui12, try a different USB port, use a different cable, and avoid hubs. Close other applications that may be using the mixer as an audio device, then reopen the recording program.

If recording starts but one or more tracks are silent, check the channel routing in the recording application and verify that signal is reaching the selected Ui12 input. If a track records the wrong source, reassign that track to the correct input and test again.

Clicks, small gaps, or stops during long recording sessions may indicate USB instability or buffer settings that are too low. Increase the audio buffer size in the recording application if dropouts occur, but be aware that this can raise monitoring latency. If the problem continues, test with a shorter cable or a different recording application to identify the failing part of the setup.

Because the Ui12 is primarily a live mixer rather than a dedicated studio interface, treat full multitrack capture as a configuration that should be tested before the event. Verify the number of assignable USB channels available in your current firmware and plan the session around that limit.
