However, note that you cannot select Structures
which contain the same Bank, e.g., the Structures
And A/B, or A and AB/CD.
When the Velocity Mix function is in use, the S-
220 is eight voice polyphonic.
To turn the Velocity Mix function off, simply push
any of the Structure Buttons.
The Velocity Mix function involves two perform-
ance parameters.
This can set the threshold level (minimum volume)
at which the Velocity Structure can sound.
You can set the minimum strength of your key
touch required for the Velocity Structure to sound
from 0 to 127. When the value is higher, a strong-
er playing manner is required, therefore, only by a
very strong playing manner, can you hear both
Structures.
This sets the maximum volume of the 2nd Struc-
ture when receiving the maximum volume mes-
sage via MIDI, from 0 to 127.
