different values across the pedal’s travel. At KMI we use Roland EV-5 expression pedals without
issue.
Third, check to make sure that your expression pedal operates on the correct voltage. All KMI gear
operates from 0 to +5 volts. If your expression pedal goes beyond that there will be a lot of pedal
travel that appears to do nothing.
Note:
Volume pedals
do not
work with the 12 Step or any KMI controller with expression pedal input — at
least, not without some modifications... With some basic soldering skills a volume pedal can be modified into
an expression pedal. There are also some workarounds:

corner-3-volume-pedal-as-an-expression-pedal/
Also note that most volume pedals use logarithmic tapered
pots as opposed to linear pots — this will have an effect on the curve/ response of the pedal.
4.9.21 Does MIDI sent to the Expander’s input get passed out
the MIDI Out? Like a MIDI Thru?
No, the MIDI Expander’s input does not behave like a MIDI Thru (pass the input out the output).
The Expander’s MIDI input is exclusively for getting MIDI into a connected computer (like a MIDI
interface) or for
external control
of the 12 Step.
4.9.22 MIDI notes are always an octave off in [insert software/
hardware here]. Is something wrong?
Nope.
There are actually multiple MIDI note number to note name conventions — different companies
follow different standards. KMI follows the C3=60 paradigm (as does Ableton, Logic, MainStage,
and more), while other companies follow the C4=60 paradigm (Native Instruments and others). It’s
even possible to run into a C5=60 standard, but that is much more rare.
If all MIDI notes appear to be an octave off, it simply means there are two different note naming
standards involved. It’s only the note
number
that matters —
the
name
is irrelevant.
4.9.23 12 Step only shows up as “USB Audio Device” or “USB
MIDI Device” when connected. Is something wrong?
If you’re on Windows XP, then nope, nothing is wrong. Windows XP lists any class-compliant USB
MIDI controller as “USB Audio Device” rather than the actual port name. The correct port name
should be displayed on Windows 7 and 8, as well as all versions of Mac OS.
If you would rather it show up as something else, it is possible to change the displayed port name.

If you’re on Mac, then this is an issue easily fixed.
1. Unplug the 12 Step from the computer
2. Open Audio MIDI Setup (located in /Applications/Utilities/)
