ARTURIA – KeyStep – USER’S MANUAL 39
 When the external source is not running, KeyStep will function according to its
internal clock at the last known tempo.
 KeyStep will pass the synchronization messages it receives from the external
source to all three clock outputs, and will convert all clock types to MIDI clock for
the MIDI and USB outputs.
7.2.1 Sync In/Out types
The MIDI Control Center can be used to configure the KeyStep to send and receive one
of the following types of clock signals at the Sync input and output connectors:
 1 step (Gate)
 1 step (Clock)
 1 pulse (Korg)
 24 pulses per quarter note (ppqn)
 48 ppqn
The default rate is 1 step (Clock).
7.2.2 Clock connectors
There are several types of connectors that have been used for musical synchronization
purposes over the years. Here’s a chart that indicates the best kinds to use when
connecting older devices to KeyStep:
Connector type
Signal(s) sent
1/8’’ mono (TS)
Clock pulse only
1/8’’ stereo (TRS)
Clock pulse and start/stop
1/8’’ stereo (TRS)
plus DIN sync adapter
(not included)
Clock pulse and start/stop
You can use optional DIN sync adapters to connect to devices which utilize DIN sync
messages. Check the owner’s manual for your device if you are not sure which sort of
sync capabilities it has.
