5.3. The Four Sequencers
The KeyStep Pro has four sequencers, each of which can hold 16 patterns/sequences. And
as each sequence can be up to 64 steps in length, you have 4096 steps to fill! Your actual
sequences can be much longer because you can chain sequences together: for example,
play sequence A three times, followed by sequence B two times and ending with sequence
C once. Don't forget that the sequencers are polyphonic, capable of stacking up to 16 notes
per step.
The KeyStep Pro thus enables you to create and play up to 64 unique sequences wherever
you go. And in spite of its small footprint, there are lots of ways to modify your sequences
during a performance. We'll cover those later in this chapter.
Sequences can be stored in Projects. A Project is a collection of sequences that you create
for a specific event, such as a recording session or a performance.
5.3.1. Exploring the Sequencers
A sequencer will play a series of notes, stored in steps. Per note, each step can store a pitch
value, a velocity value, a gate time, a time shift and a randomness value. These values will
be transmitted over MIDI (via the USB or 5-pin DIN connectors). They will also be sent to the
Voice outputs corresponding to the tracks; for example, for controlling a modular system.
Once stored, the steps are referred to as a Pattern. Patterns can be modified, copied and
chained together.
The 64 steps are grouped into four pages: page 1 holds steps 1-16, page 2 holds 17-32, page
3 holds 33-48 and page 4 holds 49 to 64.
5.3.1.1. Using the Transport Buttons
You control the sequencers with the three Transport buttons; Record/Quantize, Stop, and
Play/Pause/Restart.
Each button has an additional function when creating a sequence:
•
SHIFT + PLAY will restart a sequence.
•
SHIFT + Record/Quantize will toggle between quantized and unquantized
recording mode.
•
Pressing Stop repeatedly will clear any stuck notes.
