Sequencer

KeyStep has a sequencer and arpeggiator. You can record eight different sequences, each of which can contain up to 64 steps. The arpeggiator generates notes based on the keys you press and plays them according to the Arp mode setting.

Seq/Arp switch

If this switch is set to Seq, you can play or record sequences. Controls in this area select which sequence is currently active and the time step at which it will play. When the switch is set to Arp, the controls select the pattern and time step for the arpeggiator.

Seq/Arp modes

The function of the Seq/Arp Mode encoder changes depending on which mode is selected. In sequencer mode, it activates one of the eight available sequences. In arpeggiator mode, it selects which pattern will be used to play the notes held on the keyboard.
