Shift A & B drops you to Eb tuning at -m2, then to D at -M2. You are dropping a minor 2nd, or a Major 2nd. This is where you increase or decrease the pitch shifts in semitone steps.
Detune A & B adds or subtracts 50 cents to the Shift values above, in 1 cent increments. Fine-tuning Shift A & B values, by up to +/- one quartertone. You might use this to match an instrument that isn’t exactly tuned to A440.
But usually, it is used to offset shifted pitches by a very small amount, for a detuned (chorusing-like) effect. Think of it like the EVH micropitch effect for W/D/W fatness, or an automatic double-tracking effect. Sounds like multiple guitars / instruments playing together (or the “hoover” effect with detuned sawtooth oscillators in synthesizers).
You’ll hear what I mean with settings like this:
- Mix: 50
- Shift A & B: Uni
- Detune A: -10
- Detune B: 10
You can enhance the triple-tracking illusion with very slight amounts of delay, such as this:
- Delay A: 0.010
- Delay B: 0.020
- Feedback A: 0
- Feedback B: 0
- Pan A: -25, -50, or -100 (narrow to wide spread)
- Pan B: 25, 50 or 100 (narrow to wide spread)
Of course, this is in a stereo setup. Works almost the same with mono, though. All this will come in handy across many H9 / H90 algorithms with similar features. Polyphony uses the newest, most advanced SIFT technology to get you there.
