ARTURIA – KeyStep – USER’S MANUAL 65
Next we’ll go through those parameters one-by-one.
10.9.3.1 Sync Clock In/Out settings
KeyStep 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
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.
10.9.3.2 Sync Clock Start
When KeyStep 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.
10.9.3.3 Next Seq
This parameter decides how quickly the KeyStep 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 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.
10.9.3.4 Transposition Input port
Use this to tell KeyStep which MIDI port will receive the transposition request.
10.9.3.5 Transpose Input channel
Instructs KeyStep which MIDI channel will set the transposition amount.
10.9.3.6 Transposition Latch
This allows you to choose whether a sequence will be transposed momentarily or
latched. With either setting the transposition will happen immediately; the difference is
what will happen once the key is released.
When Latch is Off the sequences will transpose back to the center pitch immediately
after the key is released. When Latch is On the sequences will stay transposed after the
key is released, and continue at that transposition until another key is pressed.
