DP-01FX Appendix
The line of symbols on either side of the center square gets shorter as the played note approaches the �target� and the center square fills when the string is in tune:
Changing the tuning Most instruments are tuned to A=440Hz. If you
are playing with another instrument that cannot be tuned, you may want to change this value, that is, tune your guitar to the other instrument. Use the jog wheel to change the reference tuning away from 440Hz if you need to do this.
Noise reduction
When you are recording, the background noise of microphones, or the noise from guitar amplifiers, etc., may be too loud. The DP-01FX allows you to �gate� this noise, and only open the gate when the input signal goes over a certain level. This only takes effect when the MULTI effect is enabled.

Set the level at which the gate opens to a value of: OFF (the gate is always open), or from 1 (the gate will open easily, with very quiet sounds) to 60 (a lot of force�a very loud sound�is needed to open the gate).
Using a noise gate like this sometimes requires a little work to make sure that you don�t accidentally cut off quiet parts of a song. Before you make a recording using the noise gate, it�s a good idea to rehearse the whole part to make sure you�ve got the right gate level.
