15. Operation under GSIF (Gigasampler Interface)
15.1 Windows 98/SE/ME
The GSIF interface of the DIGI96 series Windows 98/SE/ME driver allows direct operation with
Gigasampler and Gigastudio, with up to 8 channels, 96kHz and 24bit. Additionally the driver
supports multi-client operation. For example ASIO can use channels 1/2 and Gigastudio (with
GSIF) channels 3/4 simultaneously, and so on.
In case more than 2 channels shall be used under GSIF, activate 'Force ADAT' in the Set-
tings dialog before starting the software.
Gigasampler/Studio requires a lot of the computer’s calculation power. An optimum performan-
ce is achieved with a stand-alone GSIF PC. Else we recommend not to use the DIGI96 ASIO
driver, but the ASIO Multimedia driver. It can be set to much higher latencies (i.e. 750 ms),
thus providing a problem-free simultaneous operation of ASIO and Gigastudio. Gigastudio itself
will still work at a very low latency.
The DIGI96 series requires identical formats when used in multi-client operation! All pro-
grams simultaneously accessing the hardware MUST use the same sample rate and bit
resolution. Otherwise de-tuned sound or no sound at all will be heared.
Additional simultaneous operation of GSIF and ASIO requires to use different channels. As
Cubase VST always uses tracks 1/2 these tracks must not be activated in Gigastudio/Sampler.
The tracks activated under GSIF have to be de-activated in ASIO.
Please note that the ASIO Multimedia driver will use the maximum bit resolution by default. If
the bit resolution of Gigasampler/Studio and other programs do not match, audio output will be
stopped, until the settings match and a reset is initiated ('Reset Devices' or software restart).
15.2 Windows 2000/XP
Basically as under Windows 9x. Differences: GSIF under W2k/XP uses a modified interface,
which needs interrupts (similar to ASIO). Therefore the user can now set and change the laten-
cy (under W9x latency was fixed inside Gigastudio). However, when using the Hammerfall
DSP, the latency is always the same as the one selected for ASIO operation. This can cause
performance problems on slower machines when using GSIF and ASIO at the same time.
Please note that the W2k/XP driver fully supports multiclient operation, including the combina-
tion MME/ASIO. So for example Cubase, Gigastudio and Sonar can be used simultaneously,
provided each of these programs uses its own audio channels exclusively. Please also note
that Gigastudio is running unexpectedly in the background (thus blocking its assigned audio
channels), as soon as the Gigastudio MIDI ports are used – even when Gigastudio itself hasn't
been started.
