Clock and Reset Outputs
The clock and reset outputs are used to convert MIDI clock messages into pulses that can be used to
drive analog sequencers. MIDI clock ticks received by the K1600 will be output as pulses on the clock
output. The MIDI song stop message will cause the reset output to pulse for a short time. (approx. 20ms)
This can be used to reset analog sequencers when a MIDI sequencer is stopped.
Normally each MIDI clock tick received causes an output pulse on the clock output. There are 24 pulses
per beat in MIDI. It may be desirable to divide the MIDI clock to some lower rate. Divisions from 1-48 are
supported. Sending a program change command of 1-48 to channel 16 will set the clock division to any
value from 1-48 respectively.
Program change 1-48 – Clock output divide amount (1-48)
•
The clock output will pulse for approx. 5ms. The reset output will pulse for approx. 20ms.
MIDI OUT / THRU Switch
Because the K1600 can act as a MIDI expander for other modules such as the K4815 Pattern Generator,
the MIDI output jack can be used either as a THRU connection (for daisy-chaining more K1600s or other
instruments) or as the MIDI OUT jack for a module connected to the internal MIDI expansion port. If the
MIDI OUT / THRU switch is set to OUT, MIDI received on the internal MIDI port will be output on the MIDI
OUT jack. In the THRU mode, MIDI input to the K1600 will be relayed through the unit. Note that this is a
soft-thru connection so that the K1600 can also send its own data from the THRU port. There will be a
short delay in relaying messages which will accumulate as more units are daisy-chained. (about 1-2ms
per module) Also note that SYSEX messages sent through the K1600 cannot have a payload greater than
64 bytes. For software updates or bulk dumps to down-stream equipment, please plug this equipment
directly into the source and not pass it through the K1600 when performing these functions.
Using the MIDI Expander Port
The K1600 can be used as a MIDI breakout board for modules such as the K4815 Pattern Generator. A 10
pin IDC ribbon cable must be connected between the two modules. Observe the correct polarity of the
cable, and connect it to X11 on the K1600 and to the appropriate port on the other module.
The connected module will receive all MIDI messages received on the MIDI IN jack of the K1600. If you
wish to get MIDI output from the connected module, move the MIDI OUT switch to OUT. This routes MIDI
data from the connected module to the MIDI OUT jack on the K1600. Note that the MIDI THRU function of
the K1600 cannot be used when the connected module is using the MIDI OUT jack.
The setup function on the K1600 can be used to place the connected module into its SETUP / TEST
mode. Click the SELECT switch until both MIDI LEDs are flashing. Place the switch in SETUP mode to
hold the other module in its SETUP / TEST mode. This can be used to enable MIDI learn mode and
calibration mode on the connected module.
