Controls the amount of pitch shift for A in cents (1 cent = 1/100th of a semitone).
Pitch Shift B [PICH-B]
Controls the amount of pitch shift for B in cents (1 cent = 1/100th of a semitone).
Reverse Delay Buffer A [RDLY-A]
Controls the length of the reverse time buffer for A. 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.
Reverse Delay Buffer B [RDLY-B]
Controls the length of the reverse time buffer for B. 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.
Reverb Mix Level [VRB-MX]
Selects the Reverb Mix level.
Reverb Decay Rate [VRB-DC]
Selects the Reverb Decay rate.
Feedback A [FBK-A]
Controls level of Feedback A.
Feedback B [FBK-B]
Controls level of Feedback B.
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
