Eventide Modfactor - Questions about type and waveforms

[ndrly]

Okay, so I have been reading the manuals for the Eventide Stompboxes. Very interesting, I will try them out first chance I get. Maybe even purchase them.

But I think the ModFactor manual is quite vague - like, I've seen some of the waveforms and types, no description, and thought "***???"

Okay, so I will list down the types and waveforms. If it has a question mark, that means I’m unsure. Anything with an “???” means “I have no freaking idea”.

Please correct me if you think I’m wrong.

CHORUS
Liquid - ???
Organic - ???
Shimmer - ???

PHASER
Negative – Negative feedback?
Positive – Positive feedback?
Feedback - ???
Biphase – Mu-Tron Biphase?

Q-WAH
Wah-Wah – Everyday run of the mill Crybaby
V-Wah – Has a more vocal quality, kind of like a vocoder/talkbox?

FLANGER
Positive – Positive feeback?
Negative – Negative feedback?
Jet - ???
Thru-0 - ???

MODFILTER
Lopass – Low-pass filter
Bandpass – Band-pass filter
Hipass – High-pass filter

ROTARY
Standard – Normal-sized cabinet
Giant – Large cabinet

TREMELOPAN
Bias – Tremolo via biasing the output valves, eg Vox AC30
Opto – Tremolo via a light bulb and photo resistor, eg Fender Deluxe/Twin Reverb

VIBRATO
Modern - ???
Vintage - ???
Retro - ???

UNDULATOR
Pitch - ???
Feedbck - ???

RINGMOD
DC - ???
AC - ???

Wave
SINE – Sine wave
TRIANGL – Triangular waveform
PEAK - ???
RANDOM - ???
SQUARE – Square waveform
RAMP – It just goes up, doesn’t come down
SQUARE – Why is SQUARE listed twice?
SMP/HLD – Sample and hold filter
ENVELOP – Controlled by the sensitivity of your playing
ADSR – Similar to ENVELOP, but how is it different?

I take it you looked at the demo?

I've been looking at the "Undulater" effect... tasty!
anyone know if i can get that style of effect in a compact/single pedal?

[ndrly]

Can someone please answer my question?

I'm sure the Modfactor is a very interesting pedal, but I want more answers to the questions about types and waveforms.

Organic - "
Shimmer - "

PHASER
Negative – Negative offset of time relative to input signal
Positive – Positive offset of time relative to input signal
Feedback - feedback, AKA regeneration, the signal is sent back into itself.
Biphase – two phase circuits in parallel

Q-WAH
Wah-Wah – Everyday run of the mill Crybaby
V-Wah – who knows, I wouldn't assume anything

FLANGER
Positive – I believe this is the same time principle as phaser, just different effect voicing. I could be mistaken though.
Negative – "
Jet - extreme feedback and depth, perhaps with some dirt added
Thru-0 - Through zero means inclusive of both positive and negative cycles, a full 360 degrees.

VIBRATO
Modern - same answer as chorus.
Vintage - "
Retro - "

UNDULATOR
Pitch - "Undulator" is not a known effect, so there is no point in guessing the values. Try it and see.
Feedbck - "

RINGMOD
DC - fixed settings, probably fixed pitch
AC - modulated settings, probably modulated pitch

Wave
PEAK - ??? good question, maybe a reverse sawtooth (ramp down)
RANDOM - random! What else?
RAMP – ramps up and then drops sharply: a sawtooth wave
SQUARE – Why is SQUARE listed twice? good question, maybe one is a pulse wave.
ADSR – "Similar to ENVELOP, but how is it different?" see below

ADSR stands for "attack, decay, sustain, and release" which are values of an envelope. Attack is the time it takes the envelope to go from zero to 100%; decay is the time it takes to go from that initial 100% to the level set by 'sustain'; sustain is a fixed chosen level somewhere between 0 and 100%; and release is the time it takes to drop from the 'sustain' level down to zero. IOW the "ENVELOP" setting follows the envelope of your input signal, whereas that ADSR setting follows the values of the ADSR settings; the envelope attack is triggered by your input signal crossing a threshold.

The modfactor manual is iffy, I think because they expect the pedal to appeal to experimenter / tweaker types who would prefer to build sounds outside of presets, but maybe Eventide did miss the mark somewhat. I'm just going to add a little to Bongo's post. The Undulator is an effect from other Eventide products. Because I am becoming a near-"fanboy" of these pedals I went ahead and found the description of the Undulator from the H8000 manual for you. "Dynamic tremolo from 2 delays and 2 detuners in a mixed series/parallel configuration. BIAS sets how the LFO dynamically reacts to input level. An ethereal texture from H3000 days. Written by ITALO DE ANGELIS..but don’t let that scare you. Mono in, stereo out." The last thing I'd add is, I will try to recreate the shimmer / organic / liquid chorus modes using just the parameter knobs (sans mode knob), but I do they they are unique characters.

[grovest]

OK, I experimented with the peak waveform, and how I'd describe it is like triangle but with a little pause at zero.

[whoatherechunk]

that undulator effect sounds sick.

I actually tried posting something like this on the Eventide forum and got NOTHING!!!

lemme try out the wave section...

PEAK - I think its resonance. They go by many names: Res, Q, Peak... its how squelchy u want your signal to be.
RANDOM - by random, do they mean a random LFO or random waveform?
SQUARE – Square waveform
RAMP – It just goes up, doesn’t come down ramp is a trapezoid wave, something like a triangle wave but with a flattop.
SQUARE – Why is SQUARE listed twice?
SMP/HLD – Sample and hold filter
ENVELOP – Controlled by the sensitivity of your playing
ADSR – Similar to ENVELOP, but how is it different? what bongomania said
