               DIGI32 Series     24 Bit PCI Digital In/Out Card

              Important informations Using ASIO Version 1,0,0,6


New:

Version 1,0,0,6 is more compatible to Logic 4.0.


Before:

Version 1,0,0,5 finally supports all cards of the DIGI32 series. There are two drivers available:

ASIO DIGI32/2 is a 2-channel driver, supporting DIGI32, 32/8 and 32 PRO in SPDIF mode. The 32 PRO can be used with up to 96 kHz.

ASIO DIGI32/8 is a multi channel driver for the DIGI32/8, supporting both 2-channel mode (SPDIF) and 8-channel mode (ADAT) with this card. The output format depends on the used number of master busses. If only 2 channels (1 master bus) is active the output format is SPDIF, when more than 2 channels (more than one master bus) is active the card's output switches to ADAT mode. Attention: as long as a ADAT signal is present at the card's input the output will always stay in ADAT mode, even when only 2 channels are used! This method ensures that even with only 2 channels used it is possible to use ADAT format on the output.

With ASIO de-activated in background it's now possible to use the MME interface.


Older Infos:

The included drivers are now able to share an interrupt under Windows 95/98. This was tested using SCSI-controller, USB, graphics cards and multiple DIGI's - all sharing and using the same IRQ. The operating system does not support IRQ-sharing with the following devices: EIDE-controller, ISA-bus-cards und -devices (PS/2 mouse etc.).

Using ASIO we discovered a problem with IRQ-sharing with the USB controller, which we think is caused by too long response times of the Windows USB drivers. ASIO plus IRQ-sharing with USB leads to a stuttering playback. We therefore recommend to disable USB in the Device Manager (Properties, 'Deactivate in this hardware profile').

This ASIO driver supports mnulticard usage, the 32/2 driver also mixed card usage. Important: The cards MUST be synchronized! This is done as usual using the optical input signal, which has to come from a common clock source (digital mixing desk) or several synchronized ADATs. Under Windows MME the unsynchronized cards will only drift in their absolute positions, but with ASIO it will periodically come to heavy crackling distortions, that slowly rise and fall.

All cards operate fixed in AutoSync mode, so the external clock source has to be master!

Please delete the old RMEAUDIO.INF (see readme.txt), as the ASIO DLL will not be installed else! After installation start Cubase, choose ASIO control under 'Audio/System' and choose the device 'ASIO DIGI32/8' or 'ASIO DIGI32/2' - you 're done!
