Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 35)

4.1.6.2. Clock In/Out Connectors
Over the past few decades, several types of connectors have been used for musical
synchronization purposes. Here's a table that indicates the best kinds to use when
connecting older devices to KeyStep Pro:
Connector type Signal(s) sent
1/8'' mono (TS) [1] Clock pulse only [1]
1/8'' stereo (TRS) [2] Clock pulse and start/stop [2]
1/8'' stereo (TRS) plus DIN sync adapter [2] Clock pulse and start/stop [2]
You can use a 3.5 mm jack to 5-pin DIN adapter 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.
If Sync is set to an external source and a TS connector is used, the sequencer needs to be
armed before it can start when receiving a clock signal. You must press the Play button to
arm the sequencer. For example:
• If the Play button has been pressed but no clock signal has been received, the
unit will wait for a clock signal and only start when it receives one.
• If clock signals are being received but Play is not active, the unit will start as soon
as you press the Play button.
If Sync is set to an external source and a TRS connector is used, the KeyStep Pro will follow
the master and will:
• Play on receiving a high-state signal and clock,
• Pause on receiving a high-state signal and no clock, or
• Stop on receiving a low-state signal, with or without clock.
