Arpeggio Direction

Controls: Sgram/PT Dialog >> Pitch-to-MIDI >> Setup
Changes: ADv=n, AAv=n

When Arpeggio is active (non-zero), repeated clicks of the Direction button change the chord note sequence direction.

The default is '/', which indicates a rising pitch. The root is played first, then the remaining notes of the chord in increasing pitch.

Clicking gives '\ ' to indicate a falling pitch. The highest note is played first, then lower notes down to the root.

A second click gives /\ ', which alternates between the rising and falling directions. A third click returns to the default rising direction.

Direction is especially useful for strumming with instruments like guitars and banjos. Note that for a conventionally-strung guitar, a down-strum is a rising pitch, and an up-strum is a falling pitch.


MIDI Changes Script:

Use ADv=n to set the Arpeggio Direction for Voice v to the value of n, which may be any unsigned integer or valid expression, including current MIDI control values, random values, current computer keyboard states or mouse position, input or buffered notes, or oscillators. If the value is zero, the direction is rising; any other value sets it to falling.

Alternatively, you can use x instead of a value to toggle the current state. For example, AD2=x toggles the current Arpeggio Direction for Voice 2.

Similarly, use AAv=n to set Alternate mode. This is a separate command to allow more control; using both commands, you can set the starting direction of Alternate mode.

You can use "voice" 9 to set or toggle Arpeggio Direction or Alternate for all 8 voices at once.
