Using the FW­1884 with TASCAM GigaStudio (GSIF)
The Windows driver for the FW­1884 implements the GSIF (Giga Streaming Interface)
protocol, for high­performance operation with TASCAM GigaStudio software. The GSIF
driver is installed automatically with the FW­1884 driver; there is no need for a separate
installation step.
The FW­1884’s GSIF interface always operates at full 24­bit resolution, although
GigaStudio has settings which can dither output to lower resolutions in special situations.
To use the FW­1884 as your GigaStudio output device, make sure the FW­1884 is
plugged in and turned on, and then start GigaStudio. When the main screen appears,
select the Settings | Hardware/Routing page. Use the drop­down combo box labeled
“Hardware” to select the FW­1884. If you will also be using the FW­1884’s MIDI Inputs
to connect a keyboard or other controller, you should select the FW­1884’s MIDI Input
ports in the drop­down boxes labeled “Midi In Ports.”
IMPORTANT: Be sure to click the “Apply” button to activate changes you
have made in this screen!
All eighteen output channels of the FW­1884 may be utilized with GigaStudio. Since
GigaStudio allows individual pairs of channels to be enabled via its Settings |
Hardware/Routing page, it’s easy to control the number of active channels that
GigaStudio is using. Channels that aren’t selected for use in GigaStudio are available to
other applications via MME/WDM or ASIO since the FW­1884 is a true Multi­Client
device.
Here is a chart that shows the association of GigaStudio channel numbers
with FW­1884 outputs:
