The Blues Scale module produces individual pitch voltages and an S-Poly signal representing the notes in the blues scale.

The small yellow numbers show the number of semitones difference in pitch between the outputs.

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 fused 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.
