NOTE CAL
When NOTE CAL is highlighted, pressing the CURSOR button takes you into the NOTE
CALIBRATION menu. Note calibration allows you to run a full-range calibration procedure,
which ensures the oscillators remain in tune for every playable note. During note calibration,
the Sub 37 “listens” to each note the oscillators produce and then adjusts them to the
expected pitch. The control voltage required to produce that pitch is recorded and saved in
the Sub 37’s internal memory.
NOTE: Note calibration is not the same as the FINE TUNE knob on the front panel. FINE
TUNE adjusts the overall reference pitch for the synthesizer, allowing you to quickly bring the
synthesizer in tune with other instruments. The two operations do not depend on each other.
Because the oscillators in the Sub 37 are extremely stable, note calibration should rarely need
to be performed.
To run note calibration, choose the range of notes you wish to calibrate, and press SAVE.
The standard note range is the full range of notes the Sub 37’s oscillators can produce (MIDI
notes 15 through 116). Because calibration is a slow process, if you only need to calibrate a few
notes, you can save time by choosing a smaller note range. Normally, however, you should
calibrate the full range.
START NOTE
This chooses the lowest note number to be calibrated. It is best left at 15 unless you
have a very specific reason for doing otherwise.
END NOTE
This chooses the highest note number to be calibrated. It is best left at 116 unless you
have a very specific reason for doing otherwise.
PRESSURE CAL
When this is highlighted, pressing the CURSOR button takes you into the PRESSURE
CALIBRATION sub menu which allows you to set values for the precise tracking of aftertouch.
SENSOR
This is a real-time readout of the aftertouch sensor’s current value. You can press any
or no keys to observe the typical minimum value (no pressure) and maximum value (a
lot of pressure). Some keys may have higher values than others.
MINIMUM
To achieve the full range of response to aftertouch set this value to the lowest SENSOR
value while not touching any keys. (If you want aftertouch to work only when you press
the keys significantly harder, set this value higher than the lowest SENSOR value.)
Press CURSOR to highlight the numeric value for MINIMUM. While this value is
highlighted, press the SAVE button to capture the current SENSOR value as
the MINIMUM value.
MAXIMUM
To achieve the full range of response to aftertouch you will want to set this value to
the highest SENSOR value while applying full pressure to multiple keys simultaneously.
Press CURSOR to highlight the numeric value for MAXIMUM. While this value is
highlighted, press the SAVE button to capture the current SENSOR value as the
MAXIMUM value.
