These 16 keys act as additional selection keys, e.g. to address one of 16 sub-menus or to extend the
number range (like bank keys). They are labelled 1-16 on the case (white characters on black background).
VALUE / NUMBER KEYS
The remaining keys are numbered 1-64 (black characters on white background). They are used to enter
numerical values. The number range may be 1...64 or 1...128 or –64...+64 depending upon the function. In
the case 1...128 the numerical distance between two steps is 2. In the case –64...+64 the numerical
distance between two steps is 2 and the middle position (or zero position) corresponds to key no 32. Most of
the part parameters use this data range. This is used also for relative data. In this case the key no 32
represents the original preset value.
If it is necessary to input an exact value (e.g. program no) the numbers above the keys help to find the right
key. For other parameters (like volume, pan, effect) the exact value may be not so important. In this case is
valid: more left = smaller value / more right = higher value.
The meaning of the keyboard keys in different menus are shown in the table on the next page.
