What the hell is MODFY DLY O/P — the x-knob label on the flanger (and chorus|organic)? I have the stompbox, not the H9, but tweak using H9 Control on iPad. I searched the (latest) manual, this entire forum and I got as far as discovering that it’s “delay offset.” I assume MODFY is knob-speak for “modify.” So can somebody explain why I would want to offset the delay? I of course played with it, and can’t hear any difference. Offset what to what? Is it a stereo panning thing (like DEPTH in other algos), or something more elemental to the flange itself? 

Thanks in advance. 



I see from the ‘Get More Out Of Your Flanger’ thread you’ve been digging deeper.  Here’s an old reference link, but still valuable in its clear and progressive explanations.  My take on the Eventide implementation follows.

Using Short Delay Effects



Think of the MODFY DLY O/P like the ‘manual’ control on an MXR M-117.  It’s a very short delay time (milliseconds, or less), and the heart of flanging, chorus, ADT, and Haas-type FX.  It’s the ‘center frequency’ starting point, from which a RATE or SPEED range will deviate.  The shortest delays provide a higher apparent ‘pitch’, with relatively longer delays shifting the frequency cancellations lower.

To best hear what the parameter does, turn the DEPTH control down to 0.  In the preset below, you won’t hear any of the slow, sweeping SPEED modulation.  The DEPTH control will ‘add’ the LFO modulation to the ‘manual’ setting of MDO.   Turn DEPTH up to 50, and you’ll introduce the modulation cycling.

I mapped the MODFY DLY O/P parameter to an expression pedal; sweeping the entire range from 0-99.  If you don’t have one, you can use the ribbon in the H9 Control app, or dial the physical control on the stompbox itself. The preset becomes a wah-like foot control over the flanging sweep.

The INTENSITY parameter is set high, for an exaggerated effect.  It’s a multi-purpose parameter, depending on the algorithm.  From what I understand, it’s mainly feedback / regeneration here.  But you can hear how resonant delays can be used for vocal formant FX, and in generating discrete ‘pitches’.


CHORUS is based on slightly longer delay times, so the entire MODFY DLY O/P range will shift (as compared to the FLANGER).  With DEPTH still at 0, sweeping the span of MDO will give you more of a pitch deviation, from adjustments to the longer delay times.  INTENSITY is multi-faceted (I believe wet/dry balance + some feedback here).  Turn INTENSITY down to 15 to get closer to a ‘wow & flutter’ effect in an EchoPlex.

With exploring a ModFactor algorithm, or when emulating a ‘classic’ effect, it’s best to start with the entire 2nd row of parameters at zeroed or neutral settings.  See the examples above.

As a Hint, I wrote:
When venturing into the 2nd row of controls, I like to hit the TAP button once, to synchronize the LFOs.  Do it again before saving the preset.  Maybe overzealous, but safe practice.

The DEPTH & SPEED MOD, MOD RATE, and MOD SOURCE controls are the keys to multiple modulation effects.  Keep in mind that these parameters ‘add’ to the main settings in the top row of controls.  They’re good for creating – for example – an audio triggered PHASER, that also has a sweep cycle, or rate changes in a ROTARY effect.  But they can also be used subtly, to add an asymmetrical ‘throb’ to a UniVibe emulation.
