"Sticky Note"

Question: When I play "B" and "C" on the EWI, I get the same tone, what's up with that?

Answer: This sounds like a touch-sensitivity problem. The original EWI manual describes a method for adjusting the touch sensitivity. It is adjusted by turning the screw head loacated on the bottom of the instrument near the "earth" or "ground" plate. The correct playing area exists between two areas of imbalance. Hold your EWI's earth plate and turn the knob on the EWV so that a strident tone is emitted. By turning the screw counterclockwise you will reach an area where the sound goes nuts. Then turn the screw clockwise. You will pass through an area where the sound is correct and then into an area of imbalance again. The best place to set the screw is close to but not into the counterclockwise imbalance area. This will cure most of these type of problems.

I have encountered at least two EWI's that have this problem and it was related to the cord. The cord connecting the EWI to the EWV was damaged by people stepping on it, etc. Lastly, if the problem persists, or the problem is more like octave-jumping, it is most likely a bad ground in the EWI. If the earth plate is not grounding the instrument properly you will have this type of problem. If you are comfortable cracking the EWI open, check all connections having to do with ground including the earth plate and bend plates. Lastly, check for corrosion on the breath block.
