To use the MADI-USB Combo Card on PCs additional drivers are necessary. Soundcraft's
MADI-USB Combo card audio drivers can be found on the Soundcraft website (www.soundcraft.
com). The install package includes WDM and ASIO drivers for low-latency operation with a control
panel to configure driver settings for best performance. You do not need additional drivers for Mac.
onto your PC, you will need to restart your machine for the install process to be complete.
The Soundcraft Audio Driver settings can be found in the Soundcraft USB Control Panel. Within this menu,
there are options to adjust the streaming mode of the MADI-USB Combo Card and the buffer size from 64
samples up to 8192 samples.
large buffer size results in higher latency to your DAW. A small buffer size reduces the latency to your DAW
but can cause audio glitches and errors.
To adjust the buffer size of the MADI-USB Combo card, both the streaming mode and the buffer size
settings need to be set correctly corresponding to one another.
For example, by setting the streaming mode to 'Reliable' and then the buffer size to 1024 samples, the
system will then be running at 1024 samples and the audio will be clean. For lower buffer sizes, the
streaming mode should be set to 'Low Latency' and the buffer size to 128 samples.
A mismatch between Streaming mode and buffer size could cause artefacts in the audio and could corrupt
the audio recording. A mismatched buffer setting such as setting the streaming mode to 'Reliable' and the
buffer size to 64 samples would result in distorted audio in your recording.
To avoid artefacts and to produce a reliable recording you should select the appropriate buffer size for the
streaming mode. When a mismatch occurs, a dialogue will appear at the bottom of the control panel menu
with instructions of where to go from the current setting to make a compatible setup.
User Manual
Before you install the PC drivers, insert the MADI-USB Combo
Card into the console, connect the PC to the MADI-USB Combo
card and boot the console. Once the drivers are installed, short-
cuts for the control panel are available on the desktop or under
all programs, Harman Pro, Soundcraft, Multichannel USB Audio.
When the card is connected to the computer, task-bar icons will
indicate a device has been detected and clicking the icon will
open the appropriate control panel. When the drivers are installed
Recommended buffer size will vary depending on application,
however higher buffer sizes should be used when monitoring
from the DAW is not necessary. For most live recording
applications, a standard buffer size of 1024 samples is enough to
ensure reliable operation and clean audio.
The streaming mode settings modify the behaviour of the USB
driver for maximum optimisation when set in conjunction with the
buffer size setting. The buffer size modifies the amount of audio
data that is stored before being released into the application. A
