(KEYBOARD)
This diagram shows how the “button” keyboard of the Werkstatt (above) re-
lates to a standard piano keyboard. Although the note names shown are correct
for this layout, the actual note being produced will also depend on many
factors, including the VCO FREQ knob, etc...
The Werkstatt is equipped with a one-octave, C to C keyboard. The keyboard
features round buttons as opposed to traditional keys, but the layout is the
same. The keyboard operates with a low note priority; if more than one note is
played at the same time, the lowest note will sound.

KEYBOARD OCTAVE SCALING
Play the lowest note [ C ] on the keyboard; now
play the highest note [ C1 ]. The interval you hear
between these notes should be one octave. If
you have an electronic guitar tuner, you can use
it to verify the notes being played. If the interval
is not one octave, there is a Variable Resistor
trimmer [ VR10 ] on the Printed Circuit Board la-
beled KB TRIM that can be adjusted to fine-tune
the keyboard octave setting.
GLIDE (GLIDE KNOB)
To achieve a smooth pitch transition from one note to another, increase the
Glide amount. Turning the knob clockwise increases the amount of time re-
quired to glide from one note to another. Turning the knob counter-clockwise
will cancel the glide effect.
