14. Operation under GSIF (Gigasampler Interface)
14.1 Windows 98/SE/ME
The GSIF interface of the Hammerfall DSP’s Windows 98/SE/ME driver allows direct operation
with Gigasampler and Gigastudio, with up to 18 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.
Gigasampler/Studio requires a lot of the computer’s calculation power. An optimum
performance is achieved with a stand-alone GSIF PC. If this is not an option we recommend to
set the ASIO latency to the highest value (186 ms). This should allow you to achieve a
problem-free simultaneous operation of ASIO and GSIF. Gigastudio itself will still work at a
very low latency.
Please note: The HDSP system requires identical formats when used in multi-client operation!
All programs simultaneously accessing the hardware MUST use the same sample rate.
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.
Additionally the tracks activated in Gigastudio/Sampler have to be de-activated in the ASIO
software (for example in the Master Bus section of Cubase).
14.2 Windows 2000/XP
The GSIF interface of the Hammerfall DSP allows direct operation with Gigastudio, with up to
18 channels, 96 kHz and 24 bit.
Gigastudio requires a lot of the computer’s calculation power. An optimum performance is
achieved with a stand-alone GSIF PC. 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 multi-client operation, including the
combination MME/ASIO. So for example Cubase, Gigastudio and Sonar can be used
simultaneously, provided each of these programs uses its own audio channels exclusively. For
example ASIO could use channels 1/2 and Gigastudio (with GSIF) channels 3/4
simultaneously, and so on.
Simultaneous operation of GSIF and ASIO requires to use different channels. For
example, if Cubase uses tracks 1/2 these tracks can not be used by Gigastudio.
Common Problems
Please 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. This causes a lot of confusion, as the driver seems to
behave completely buggy, and the user does not recognize the simple reason for it – for
example simultaneous operation of ASIO and GSIF on the same channels.
In case Gigastudio loads well, load gig files too, but won't play at all even when using the virtual
keyboard: Go to Hardware/Routing and select a valid MIDI input port. Note that blank is not
valid, but <none> is.
