Usage Instructions for 4Dperception MusicTuner

4D perception MusicTuner is developed based on our patented algorithm, which could detect the absolute frequency of a tone and provides robust detection under noisy environment. You may not recognize that, so far, all the similar products on the market cannot provide a detection with relative robust absolute frequency; as a result, their products cannot distinguish the notes that have octave relations, such as C2, C3, C4, are reported as a same result C, and even report wrong frequency in an even weak noisy environment.

In version 3.2, 4D perceptionl MusicTuner covers instruments: piano, violin, viola, cello, bass, guitar, and banjo, with different styles and transposes, and provides the metronome and timing functions.

If you use this software for first time, you need to set you instrument and style if the default settings does not match your case. To access the settings panel, press 'Change' button in main panel, then you can change instrument, style, and parameter settings.

By pressing the 'UserDef' in 'Custom Define' group in setting panel, you can define strings for your own instrument if the instrument is not covered in the setting panel.

If there is any style that is not covered in the setting panel, you can also press the 'UserDef ' in setting panel to define your own style.

Please frequently check back with our version update at www.4Dintel.com.

We DO NOT recommend using 'auto' for tuning piano strings before you get familiar with this software. However, it is convenient to use 'auto' to tuning strings, including piano strings.

The right steps to use 'auto' for tuning piano strings are:

(1) use 'manual' to tune one key (any key) of piano first
(2) then switch to 'auto', tune any nearby key
(3) do not jump too many key (say one octave), if you jump too many key (say from A0 to C8), the frequency will not be detected correctly.

Button: Select String
When using 'manually' (AUTO button light is off), you need to select a string button that you want to tune the string.

It has no effect when using AUTO button light is on.
