Shifting - Cont’d

Post-Scale:

Post-Scale shifting is the easiest to understand of all the shifting types. For this type, the shift value is simply added to the scaLED note.

So if my scaLED note is C2 and the shift value is 4 and the destination is A (and still using CMajor scale) then the resulting note is

OUTA = C2+4 = E2. OUTB would be the unshifted note (C2) plus the interval value (e.g. 5) OUTB = C2+5 = F2.

If the destination was B then OUTA = C2 (no change) but OUTB = C2+interval+shift = C2+4+5 = A2.

If destination was A+B then OUTA = E2 and OUTB = A2 (i.e. both are shifted by the same amount of semi tones and can be considered

to have changed keys by the amount of shifted semitones).

So far we have looked at only using A, B or A+B as shift destinations. The fourth destination “ROOT” is an exception. With this destina-

tion the shifting type is irrelevant (and changing those values will have no effect). Instead the shift value is applied to the entire active

scale moving it forwards or backwards by the shift amount. When the scale is being shifted it maintains the interval relations between

each scale step so that the result is that the root note of the scale is shifted.

It is highly recommended that the user experiment with these different shift type and destinations. You will find that small settings

changes can result in dramatic changes in the melodies generated.
