The Chromatic Scale module produces pitch voltages representing all the notes in the chromatic scale.
The KEY IN socket is used to control which of 12 keys the scale is based on. If no voltage is connected then the key defaults to C.
The KEY IN signal is a standard 1 V/Octave pitch signal. It is used to transpose the scale by simple addition so will handle octave offsets and non-standard tuning, but it’s also used to update the helpful yellow note value labels. So the module is expecting the KEY IN voltage to be relatively stable. From an efficiency point of view it’s therefore best if things like vibrato or glides are added after this module .
Individual pitch outputs can be used for transposition, to build chords or be used in generative music patches.
The commonest application is perhaps to connect the S-Poly chord signal output from the SCALE OUT socket to Adroit modules that utilize scales.
The Chromatic Scale module is part of LSSP XL.
