First approach 2001: Trying to get access to digital sound signals through
Prodif Plus soundcard. The SEKD-Prodif Plus (Type 1999) offers both
digital S/PDIF and Alesis ADAT and the data can be accesses
To synth more than one card, the device offers a connector which can
be used to get the clock from, to synch digial interfaces.
Hardware for S/PDIF (external devices)
Second approach in 2003: Use a standard digital input device from
german manufacturer mindprint to get both S/PDIF and AES/EBU level
signals fromexternal studio devices. It can be synched from external
sources. The data can be accessed using the internal bus.
DIY-Hardware for S/PDIF
An S/PDIF interface can be created in VHDL easily using existing
sources: See OpenCores. Read a report and this discussion about this in
The physical S/PDIF interfac is tweak in order to transmit the
10-Bit data für the synthesiszer boards and to transmit MIDI-Data.
