KS1
GULBRANSEN MIDI ADAPTER
Congratulations! Your investment in a GULBRANSEN KS1 will tremendously enhance the musical
variety and pleasure obtainable from your acoustic piano.
What does the KS1 do? The Gulbransen KS1 is a simple MIDI interface for your acoustic piano. The
KS1 allows you to use your piano as a MIDI controller. The KS1 MIDI OUT jack can be connected to
any synthesizer, sequencer, or computer having a MIDI IN jack.
If the SS88 sensor strip is not already installed in your piano, refer to the installation manual that was
shipped with the KS1. The first thing you will want to do is perform a bench test to make sure none of the
KS1 components were damaged in shipping. It is much easier to resolve any problems if the system is
bench tested before installation into the piano. The general bench test procedures are outlined in the
installation manual. This manual covers the steps that are specific to the KS1. See the Setup section
below.

KS1 Operation
The KS1 is a very simple device and is easy to use. Once the setup procedure has been performed, there
are only three controls that you need to worry about. Everything you need to know is on this page!
Volume: This control allows you to set the volume of your external sound module(s).Twisting this knob
causes the KS1 to transmit a new Channel Volume* (Controller 7) message on the current MIDI channel.
Any device that is listening to that MIDI channel will set its volume for that channel to the new value.
* “Channel Volume” was called “Main Volume” prior to an agreement made by the MIDI Manufacturers Association in January 1995.
Mute: Shuts off any held notes and releases sustain and sostenuto pedals. This button allows you to easily
turn off your piano’s MIDI output.
Set MIDI Channel: By default, the KS1 transmits on MIDI Channel 1, but you can change this to any of
the 16 MIDI channels. The MIDI channel assignment is permanently stored in non-volatile memory, even
if the KS1 is turned off or the power is disconnected.
To display the current MIDI channel, press and hold the Channel button for one second. The light above
the button will “flash the channel.” For example, if the MIDI channel is set to four, the Channel light will
flash four times and go out. You can release the channel button when the light starts flashing.
To change the MIDI channel, press the + or - button as indicated on the front panel. The flashing cycle
will reflect this new MIDI channel.
To exit this function, press and release the Channel button again. The Channel light will stop flashing and
the KS1 will resume normal operation.
