Arturia BeatStep Pro MIDI/Analog Controller and Sequencer Kit with CV/Gate Cables (Black) - Manual (Page 80)

7.2. As Slave
BeatStep Pro functions as a slave to an external clock when one of the other three SYNC
LEDS are lit (USB, MIDI or CLK). When BeatStep Pro is in Slave mode:
• The Tempo controls will not control the internal sequencer while the external
source is running.
• The BeatStep Pro transport section will still perform as usual; you can still stop,
start and pause the internal sequences, and you can still record patterns.
• When the external source is not running, BeatStep Pro will function according to
its internal clock at the last known tempo.
• BeatStep Pro will pass the synchronization messages it receives from the
external source to its USB, MIDI and Clock outputs.
7.2.1. Clock In/Out rates
The MIDI Control Center can be used to configure the BeatStep Pro to send and receive one
of the following clock signals at the Clock input and output connectors:
• 1 pulse per step
• 2 pulses per quarter note (ppqn)
• 24 ppqn - standard DIN sync
• 48 ppqn
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 BeatStep 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 the supplied 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.
1. If Sync is set to an external source and a TS connector is used, the sequencer
needs to be armed before it can start after receiving a clock signal. You must
press [Play] to arm the sequencer. For example,
◦ If [Play] is pressed but no clock has been received, the unit will wait
for a clock signal and start when it receives one.
◦ If clocks are received but PLAY is not active, the unit will start when
you press [Play].
2. If Sync is set to an external source and a TRS connector is used, BeatStep Pro
will follow the master and will:
◦ play when it receives a high state signal and clock,
◦ pause with a high state signal and no clock, and
◦ stop on a low state signal, with or without clock.
