Unison stack mode transposes outer voices to musical intervals rather than just detuning them in pitch

Standard unison detunes voices by small cent amounts around the root note. Stack mode changes this: voices are offset by musical intervals — octaves, fifths, sevenths — rather than microtonal detune. The result is a built-in chord or thickening that uses the unison voice count. Combined with the center voice control, stack mode lets a single oscillator produce harmonically-meaningful layers without routing multiple oscillators. It is particularly useful for building organ-like stacks (octaves + fifth), power chords, or jazz-inflected superchords in a single patch layer.

Examples

Stack set to +1 oct: every outer voice plays one octave above. Stack set to +7 semitones (fifth): outer voices play a fifth above for a power chord effect. Combine with blend for balance.

Assessment

Set a saw to unison 3, stack mode, +7 semitones. Describe the chord character. Then change to +3 semitones. What interval is that and how does it change the harmonic feel?
