Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 102)

5.4.3.2. Real-time Recording of a Pattern
To record a Pattern, press the Record button then press the Play button to start the Pattern. If
the Pattern is already playing, just press the Record button. When the KeyStep Pro is running
with both Play and Record lit up, it is in Record mode. If it isn't running, check the sync
settings in the Utility menu by pressing 'Shift' + Project, scrolling down to Sync, pressing the
selection encoder and checking the Input parameter. It's best to set this to 'auto'.
Now play one or more keys. Whatever you play will be captured and added to the current
Pattern. You can toggle individual events ON/OFF with the step buttons.
The Tie/Rest button plays a key role in getting the sequence just right; while the sequence
is recording/looping, you can delete notes by holding the Tie/Rest button: while the button is
depressed it will erase the content of steps you're passing over.
You can also record the input from an external MIDI/USB source, but the only steps that
will be recorded are those that correspond to the current Drum note mapping. For more
information, see the Drum Map section of the MIDI Control Center [p.155] .
The active quantization setting will have a direct effect on your recording. When recording
with active quantization in a low time-division (1/4 or 1/8), the beats will be 'forced' together.
Turn quantization OFF by pressing 'Shift' + Record/Quantize to preserve the irregular feel of
your playing style or the external input.
