Note that on the Patchable
Header, the KB CV is output
as about 0.3 Volts/semi-
tone, which is equivalent
to about 3.6 Volts/Octave.
This allows the use of the
Keyboard as a wider range
controller than if it were
output as 1 Volt/Octave.
CREATING CABLES
For internal patching use the included Patchable Header cables. If you
want to patch the Werkstatt to external gear, you may want to convert
theincludedpatchcablessotheycanplugintothe1/4”(3.5mm)patch

provided by the audio output, you would only need to splice and solder
the inner conductors of the two half-cables together, and then insulate
the splice with electrical tape or heat-shrink tubing.
