9.10.3.1. Sync Clock In/Out settings
KeyStep 37 is endowed with the ability to transmit or receive clocking signals from a huge
range of vintage devices. Here's a brief look at each setting:
• 1step (Gate): Interprets the rising edge of the voltage as a Note On command and
the falling edge as a Note Off. Then it will advance to the next step.
• 1step (Clock): It is likely the input clock has a fixed period, so KeyStep 37
interpolates between the edges of the clock signal to derive a steady tempo.
• 1 Pulse (Korg): As the name implies, this is a special sync clock used by Korg
devices.
• 24 PPQ: the DIN sync used by Roland and other companies in their devices.
• 48 PPQ: the clock signal used by Oberheim drum machines, et al.
9.10.3.2. Sync Clock Start
When KeyStep 37 is slaved to an external device via the Sync input, this parameter allows
you to specify how the sequencer and arpeggiator will start:
• On Clock: the Seq/Arp will start as soon as a clock is received on the jack tip. This
mainly applies when you are using a Tip-Sleeve (TS) connector.
• On Gate Start: the Seq/Arp will start when a clock signal is received on the tip
of the connector and the start signal is high on the ring. This setting is ideal for
when using a Tip-Ring-Sleeve (TRS) connector.
9.10.3.3. Next Seq
This parameter decides how quickly the KeyStep 37 sequences will change after a new
sequence has been selected, and whether the new sequence will start from the top or the
middle somewhere.
• End: KeyStep 37 will not change sequences until the end of the current sequence.
• Instant Reset: The sequence changes immediately and starts at the top of the
new sequence.
• Instant Continue: The sequence changes immediately but transitions at the
current position into the new sequence.

If the two sequences are not the same length, the current position of the new sequence is calculated
as if the new sequence had been played from the beginning.
9.10.3.4. Transposition Input port
Use this to tell KeyStep 37 which MIDI port will receive the transposition request.
9.10.3.5. Transpose Input channel
Instructs KeyStep 37 which MIDI channel will set the transposition amount.
