If there are notes that seem to play too loudly relative to other notes, you probably need to perform a 
keyboard adjustment, described above. Most of the time this will solve the problem. There is a way to 
adjust the calibration of an individual note, however. 
 
This function only works on notes that actually play, but whose relative loudness you wish to adjust. As 
with the tuning function, you should set the volume to an appropriate level before entering this function 
because there's no way to adjust the master volume while you’re in this mode. 
 
To use this function, play some notes on the keyboard. When you find one you want to adjust, play it 
repeatedly while slowly twisting the volume knob back and forth. You should discover that the note will 
get louder ("hotter") as you twist the knob clockwise, and softer ("colder") as you twist it 
counterclockwise. Go slowly. If you play lots of different notes while twisting the knob like a maniac, 
there's no telling what the result will be. The software uses the knob's position to alter the settings of the 
last note you played. The only way to use this function predictably is to be careful to only move the knob 
AFTER you've played the note you want to adjust. 
 

Clear  EEPROM

 

 
The KS1 stores its setup information in an EEPROM, which is a small circuit about the size of a very flat 
crouton. This amazing little device will retain this setup information for 10 years without power. The use 
of this device means the KS1 has no batteries to replace. Truly no user-serviceable parts inside. 
 
There are times when it is necessary to clear the EEPROM. This will restore the KS1 to its factory 
settings. It will also erase the keyboard adjustment and MIDI output channel assignment. If you clear the 
EEPROM, you absolutely 

must

 perform the keyboard adjustment over again. To clear the EEPROM, 

press and hold the all three buttons for five seconds. The KS1 will clear the EEPROM and automatically 
reboot. The first thing you need to do is perform the keyboard adjustment, described above.
