Distance Sensor
Infrared distance sensors are very popular and even used in commercial prod-
ucts from a well-known Japanese company. This is how you can attach them to
the KB37. Please note that you need an additional battery to power the sensor
because it draws a notable amount of current and requires a stable 5V supply.
Of course you can omit the power switch and the LED to make it simpler.

Firmware Update
The unit’s internal firmware can be updated over USB. To perform this opera-
tion, the KB37 has to be put in bootloader mode at startup. Then the firmware
file has to be send via MIDI SysEx from your computer.
This is how you update the firmware:
• Switch off the unit in case it is powered on
• Press and hold the Setup button on the controls panel
• Switch on the unit
• The Setup button LED as well as the Octave LEDs will blink
• Open the SysEx transfer utility on your computer
• Send the file containing the new firmware code
• While receiving the data, the Octave LEDs will indicate the progress
• After the new firmware was successfully transferred, the KB37 will reboot
We recommend using either SysEx Librarien on OS X or MIDI-OX on Windows.
Both applications are free of charge and we found that they work well with their
default settings.
In case of an error, the unit will not reboot and may show an error condition via
a blinking Octave LED. If no error is indicated and the unit just stalls, it’s likely
that the data stream was interrupted unexpectedly.
Please check the following and retry the transfer:
• Make sure the KB37 is in bootloader mode before launching the SysEx
transfer utility. Otherwise it may not find the right MIDI port.
• Check if SysEx data is sent to the correct output port
• Try to reduce the transfer speed. The host software usually offers a delay
parameter for that.
