Lesson 14
System Procedures and Operating Guidelines
This lesson covers system functions and general notes on the Bass Bot's operation and maintenance.
In this lesson, button combinations are written as [FUNCTION] + [NOTE], where "NOTE" is a key on the
musical keyboard portion of the front panel.
Automatic Tuning ([FUNCTION] + [C#])
The Bass Bot can self-calibrate its tuning. Set the Mode switch to MIDI mode. Set the Tuning control knob
to the center position. Then press [FUNCTION] + [C#]. The Function and C# LEDs will light up for a few
seconds. When these LEDs turn off, your Bass Bot will be in tune with accuracy of ± 5 cents. Take a few
seconds to check the tuning's accuracy using a tuner or by ear by pressing the keys on the keyboard after
completion. If the desired accuracy is not achieved with the first tuning, very slightly adjust the Tuning
knob then run the automatic tuning function a second or third time. They keyboard's low C is a C2 note and
it should be 65.4Hz when accurately tuned.
System Colors ([FUNCTION] + [F#])
You can customize the system color of your Bass Bot's LEDs. While in MIDI mode, press [FUNCTION] +
[LED]. You will see the keyboard key LEDs light up in different colors. Simply press the key for the color
you want to use for the system LED color. The factory default system color is red.
Protect Your Hearing
Please be aware that many of the Bass Bot's harmonics and dynamics may damage hearing on loud
speakers and headphones. Care should be taken to avoid high volume listening for extended periods.
Bots Have Feelings Too!
It is important to understand that while designed for portability, just as with humans its performance can be
greatly affected by travel and environmental conditions, especially those which drastically differ in a very
short period of time. There are three considerations that affect tuning, especially before live audience
loudspeaker performances in a real-world professional environment.
a) Power source. Operating on batteries should be performed with fresh batteries to avoid
inaccurate tuning from low batteries, or the compact universal AC adapter designed for use in
travel.
b) Output sound source. When using headphones, it is important to realize that sound produced
so closely to the ears can appear incorrect in comparison to the sound produced through the
output jack to a speaker systems, with greater bass response at greater distances.
c) Temperature. Operating conditions should not exceed 0°C ~ 35°C. Any rapid temperature
change can cause internal condensation possibly causing tuning inaccuracy.
Examples of Extreme and Rapid Environmental Changes to Avoid:
•
Movement from excessively cold conditions, such as an automobile during winter or air-cargo hold
in freezing temperatures, into excessively warmer / humid environments (such as an indoor live
event).
•
Movement from excessively hot conditions, such as an automobile during summer, and brought
into excessively colder / hotter environments.
•
Use in direct sunlight (such as an outdoor live event), or too close to equipment such as and
air-conditioner, portable heater, or high wattage lamps or amps.
Tip!
It is recommended that the tuning function be performed before live performances after at least thirty
minutes of 'temperature stabilization' at any location greatly differing environmental conditions that of last
use. It just takes a few seconds!
