Connecting Midi - Kurzweil PC3K Series Musician's Manual

Digital
For digital audio output from the PC3K, connect a 75‐Ohm coaxial cable from the PC3K's RCA
Digital Out jack to the AES or S/PDIF input of the receiving device. You may need an RCA‐to‐
XLR adapter to connect with the receiving device. If the receiving device receives only optical
signals, you'll need a converter as well. The PC3K's Master Page (press the Master mode button)
lets you select a range of useful sample rates for the digital output.
The RCA jack labeled ʺSync Inʺ allows you to synchronize the PC3Kʹs S/PDIF Digital Audio
output sample rate to an external S/PDIF source. Although no audio signal is received by the
ʺSync Inʺ jack, its clock is received and may be used to set the output sample rate. For more,
please see Master Mode Page 1: Digital Output on page 11‐9. NOTE: Sync In is NOT a ʺWord
Clockʺ input. Only a valid S/PDIF signal is recognized.

Connecting MIDI

The simplest MIDI configuration uses a single 5‐pin MIDI cable: either from the MIDI Out port
of your PC3K to the MIDI In port of another instrument, or from the MIDI Out port of another
MIDI controller to the MIDI In port of the PC3K. There are all sorts of possible configurations,
including additional synths, personal computers, MIDI effects processors, and MIDI patch bays.
Depending on your system, you may want to use the PC3K's MIDI Thru port to pass MIDI
information from a MIDI controller to the PC3K and on to the next device in your system. You
can also connect MIDI devices to the PC3K's MIDI Out port, which can send channelized MIDI
information from the keyboard or through the PC3K from your MIDI controller.
The MIDI Thru port can be configured to serve as an additional MIDI Out by sliding the nearby
switch to the Out position.
You can also use the PC3K's USB port to send and receive MIDI. By default the PC3K will show
up as a USB MIDI device. If you choose USB Temporary Drive from Storage mode, the PC3K
will temporarily (while on that Storage mode page) become a "virtual storage device" and USB
MIDI will be disabled. Different host programs on your computer may indicate various errors as
the USB MIDI device is no longer present. Leaving Storage mode will restore USB MIDI
functionality.
USB MIDI and 5‐pin MIDI can be used at the same time; the MIDI signals will be combined into
a single 16‐channel MIDI stream.
