Diatonic

Diatonic pitch shifters track the notes that you’re playing and shift the pitch by the selected harmonic interval based on the Key and Scale that you’ve selected.

Diatonic Shifter features twin independently-controlled pitch changers (A & B) with independent delays and feedback. Diatonic tracks the notes that you’re playing and automatically adjusts the amount of pitch shift so that the resultant note is in-key. Use the Pitch A/B control knobs to set each pitch interval. Use the Control Knobs to select the key, scale and interval.

Using H9 Control (or if you’ve connected an AUX Switch), you can use Learn mode to set the key. See SYSTEM Mode section of the H9 User Guide for details on setting up an AUX Switch.

Note: Due to the limitations of Diatonic Pitch Shifting, the pitch tracking algorithm is monophonic and works best on single, isolated notes, and octaves.

Diatonic Algorithm Controls
Mix [MIX]
wet/dry mixer, 100% is all wet signal.
Pitch A/Pitch B Mix [PICHMX]
Controls the ratio of the level of Pitch A to Pitch B.Note: The A/B mix is set before the feedback delays so that feedback can continue on A or B and not be affected by new audio when the Pitch Mix control is turned completely to the opposite channel. This allows you to create a mini 'looper' effect.
Pitch Shift A [PICH-A]
Selects the harmonic interval (pitch shift) for Pitch A
Pitch Shift B [PICH-B]
Selects the harmonic interval (pitch shift) for Pitch B
Delay A [DLY-A]
Controls the amount of time delay of the A pitch shifted output. With Tempo OFF, delay is displayed in mSec. With Tempo ON, delay can be sync’d to the tempo and is displayed as a rhythmic sub-division of the tempo beat value.
Delay B [DLY-B]
Controls the amount of time delay of the B pitch shifted output. With Tempo OFF, delay is displayed in mSec. With Tempo ON, delay can be sync’d to the tempo and is displayed as a rhythmic sub-division of the tempo beat value.
Key [KEY]
Selects the key.
Scale [SCALE]
Selects the scale. The supported scales are: [MAJ]-Major, [min]-Minor, [DOR]-Dorian, [PHRG]-Phrygian, [LYD]-Lydian, [MLYD]-Mixolydian, [LOC]-Locrian, [Hmin]-Harmonic Minor, [Mmin]- Melodic Minor, [Wton]-Whole Tone, [ENIG]-Enigmatic, [NPLT]-Neapolitan, [HUNG]-Hungarian.
Feedback A [FBK-A]
Controls level of voice A Feedback. The feedback delay length is the length of either Delay A or Delay B, whichever is longer.
Feedback B [FBK-B]
Controls level of voice B Feedback. The feedback delay length is the length of either Delay A or Delay B, whichever is longer.
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
TEMPO ON / TEMPO OFF
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Active
Turn effect on or off..
LEARN MODE
Press and hold the Learn switch while playing a note and the H9 will set the key to that note..
TAP
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
