With the chromatic approch, you can easily make a "chromatic scale", up to a pre-defined chord .
The speed of the approch is set in the processor. If the value is nul, the approcah is done manually, re-pressing the note manually.

Example 1 :
to make chromatic approch up to a tonic played on track 1, grouped by 4 notes : select a chromatic approch with value -3 ( or 3 ), and play four time the tonic.
Example 2 :
chromatic approach, selecting value -2, for a chord C-E-G played three times = Bb-D-F , B-Eb-F#, C-E-G

The selection of the value for chormatic approach is made with a Selector in section Transposition, in user Tab.
First key-shortcut makes maximum approach from down. Second key-shortcut makes maximum approach from up.
Chord in the Selector must be "between two notes". Note in the middle sets null value. Each note on the left adds one half-ton from down. Each note on the right adds one half-ton from up.
Example with a Selector with X and V key-shortcuts, and a chord between "white notes" C2-B2 : X will do a chromatic approach of 3 half-tone, from down. C2 will do a chromatic approach of 3 half-tone, from down. B2 will do a chromatic approach of 3 half-tone, from top.
