Kenton Pro-4 - Manual (Page 7)

7
- a voltage output for connecting to an auxiliary input on a synth such as filter control or VCA volume.
Connect this output to the input marked VCF in, VCF fcM, Filter, etc, on your synth to control the filter cut-
off, or the input marked VCA, Volume, loudness, etc., to control volume. You could also connect this to
inputs such as portamento, pulse width, high pass filter cut-off, etc.
Cable Connections
All minijack outputs on the PRO-4 need standard 3.5mm mono minijack plug. The connection at the synth
end of course depends on what synth you are using.
THE ARP CLOCK & SYNC 24 OUTPUTS
CLOCK PULSE - (arpeggio clock)
- this output provides a 5 volt clock pulse related to the incoming MIDI clock. The ratio of MIDI clocks to
arpeggio pulses can be adjusted - (see CLOCK PULSE DIVIDE).
A 5 volt voltage will be outputed on the first MIDI clock after a MIDI start (or continue if selected) is
received, and thereafter dependent upon the CLOCK PULSE DIVIDE ratio.
You may wish to connect this to an input marked Ext. Clock In on an analogue drum machine or
sequencer. It could also be used to gate/trigger envelopes or Sample and Hold circuits in time to MIDI
clock.
SYNC 24 - (DIN 24 sync, used on SOME ROLAND equipment)
- this output provides clock and stop/start signals.
Pin 1 - Stop = 0 volts Start = 5 volts (or continue if selected)
Pin 3 - 5 volt pulses; 24 clocks per quarter note, the same as MIDI
Pin 2 - Ground
Pins 4 & 5 are not used.
Cable Connections
MIDI leads are not suitable for connecting to the SYNC 24 socket as they have different pins connected.
Use a 5 pin DIN to 5 pin DIN audio lead available from a HI-FI shop.
Connect this output to the SYNC 24 input on a TR606/808, MC202, or TB303 to synchronize these
instruments` sequencers to MIDI clock.
