USB
p
This is the USB connector of d3c. If you want to run the d3c via the USB interface (instead of
Midi) this socket has to be connected to the USB socket of your computer with a suitable
cable (A-B type). A suitable cable is included with the d3c. But each standard A-B type USD
cable will work. The computer system has to be equipped with so-called generic USB
device class drivers for Midi devices. These are included in the Windows XP™ or Mac
OSX™ operating system.
Former Windows™ or Mac™ operating systems are not supported. In these cases the Midi
interface of d3c has to be used.
If the operating system supports the USB device class drivers the computer recognizes the
d3c connection as soon as the USB cable is connected and the corresponding driver is
installed. This is normally indicated by an acoustic computer signal.
After that a new Midi Input and Output labelled USB audio device is available and can be
used in all programs (e.g. Native Instruments B4).
If an error message appears (e.g. "USB device not recognized" or similar) the required USB
driver is probably not available or not installed on the computer. It is difficult to find out the
reason why it does not work as it depends upon the hardware and software (especially the
operating system and the installed drivers) of the computer.
But we will try to give some hints in this manual and on our website provided that we hear
about such problems and their solutions.
Using the USB connection has both advantages and disadvantages compared to the Midi
connection. Please read the corresponding notes in this manual and on our website.
Midi In

This is the Midi output and the Midi Input of d3c. There are different possibilities how to use
these sockets:
• Only the d3c is used (no d3m or other Midi keyboards):
In this case Midi Out of d3c is connected to Midi In of the sound generator that is
controlled by d3c (e.g. computer with organ emulation, stand-alone organ exander). The
Midi In of the d3c remains unconnected in this case.
A typical example for this type of connection is a running sequence (e.g. with the VST
plugin B4) that is modified while it's running.
• The d3c is used in combination with one or more d3m (or other Midi keyboards):
The d3m and d3c are daisy chained via Midi In and Out. Midi Out of the first d3m is
connected to Midi In of the second d3m. Midi Out of the second d3m is connected to
Midi In of the d3c. Midi Out of d3c is connected to Midi In of the sound generator that is
controlled by the d3c/d3m (e.g. computer with organ emulation, stand-alone organ
exander). Each d3m requires a different Midi channel to be able to distinguish the
keyboards (for details please refer to the d3m manual).
If a bass pedal d3b is used (future module) the Midi Out of the d3b is connected to Midi
In of the first d3m in the chain.
If Native Instruments B4 is used the Midi channels of the d3m keyboards have to be set
