3.3. Sequence Creation
The BeatStep Pro provides an astounding array of options for music creation. Each of the
following features plays a major role in shaping a sequence:
3.3.1. Quantize Recording
The process of recording a sequence has been described in the Basic Operations chapter.
But there’s an important concept to know about recording in real time using the pads or
incoming MIDI: the notes will be quantized according to the time division you have selected.
So for example, if 1/4 is the time division setting then the recorded notes will quantize
forward or back to the nearest quarter note. And as the sequence loops you can replace
certain notes by playing a new one within the timing range of those notes.
