Change root frequency menu
This dialog allows you to change the root frequency of A(440 Hz) to any
desired frequency within two halftones. For example, when you set the root frequency
to 445 Hz and tune your guitar in standard tuning, all tones will sound
slightly higher than ”real” standard tuning. This could be useful when you want to adapt your guitar
to vocals, so that they can sing higher or lower.
Remark: This option is available only in registered version of DGT.
