Chord Memorizer Object
The chord memorizer maps individual notes to chords. You can assign one chord to
each pitch class (to C, C#, D, and so on).
The octave of the incoming note determines the octave of the resulting chord. A chord
can have zero to 12 notes in it. (Zero and one note chords can be useful for creating
scale-filters and scale-correctors).
The easiest way to use the chord memorizer is to connect its output to the instrument
that you want to play the chords, and assign it to an Arrange window track. You can, of
course, place it anywhere else in the MIDI signal path.
To create a new chord memorizer, select New > Chord Memorizer.
Chord Memorizer Parameters
Cha
All chord notes will be output to the defined channel.
Lim
Notes within this range are mapped to chords. Notes outside the range are passed
through unaltered.
Trp
The output chords are transposed by the amount set here (±99 semitones).
Example: if you map C to a chord consisting of CEG, and set transpose to 1, then C will
be mapped to C#FG#.
