No sound (when a MIDI
device is connected)
Are all devices powered on?

Moving your hand over the D
Beam controller does not
produce a sound
Could the D Beam button for the desired sound effect be lit green?
If a D Beam button is lit red, moving your hand above the D Beam
controller will apply an effect to the sound you play from the keyboard.
Not all the notes you play are
sounded
The maximum simultaneous polyphony is 128 notes. If you are playing
along with a song and making heavy use of the damper pedal, the
number of notes the RK-300 is attempting to produce may exceed the
maximum polyphony, meaning that some of the notes will drop out.
