Duplicate Effects


Recommended Posts

While looking at @hefonthefjords' great list of all FX models in the Helix (Thread Link) , I discovered that with the introduction of the Legacy Effects in Firmware 2.50 we now have multiple duplicates:


1. Dynamics: Red Squeeze <-> Red Comp (MXR Dyna Comp)

2. Distortion: Vermin Dist <-> Classic Dist (ProCo Rat)

3. Distortion: Tycoctavia Fuzz <-> Octave Fuzz (Tycobrahe Octavia)

4. Delay: Ducked Delay <-> Dynamic (TC Electronics 2290)

5. Pitch/Synth: Twin Harmony <-> Smart Harmony (Eventide H3000)

6. Modulation: 60s Bias Trem <->> Bias Tremolo (Vox AC-15 Tremolo)

7. Modulation: Script Mod Phase <-> Script Phase (MXR Phase 90)

8. Modulation: Bubble Vibrato <-> Pitch Vibrato (Boss VB-2)

9. Modulation: Analog Flanger / AC Flanger <-> (possibly) Gray Flanger (MXR Flanger)

10. Modulation: Vibe Rotary <-> Rotary Drum (Fender Vibratone)

11. Modulation: 145 Rotary <-> Rotary Drm/Horn (Leslie 145)

12. Modulation: 70s Chorus <-> Analog Chorus (Boss CE-1)

This list is possibly incomplete.


I haven't updated yet because I have a gig coming up. Did anyone compare those models yet?

I asked about this in another thread. Apparently the M Series Effects were copied en-mass and it was easier to include everything than it was to leave the duplicates out.

The secondary benefit is that if you are getting short of DSP the legacy versions will sound similar but use less DSP.

What you say makes sense but I just saw a post that showed that that's not always going to be true. The example he gave is he was able to add an HX tube screamer in a certain patch but the legacy Tube Screamer was to big. Wouldn't let him add it instead of the HX version.

Not all legacy FX are available in stereo -


Notes taken from the HXFX manual - English .pdf


Legacy effects models vary in behavior, just as on the classic Line 6 effects from
where these models originated.
• Legacy Distortion, Dynamics & Pitch/Synth effects are mono.
• Legacy Modulation & Delay effects vary in that some are mono, some stereo,
and some mono-in/stereo-out, where adjusting the effect's Mix parameter
can narrow the stereo image that is fed into them. It is best to experiment
with these effects and tweak the Mix parameter to achieve the desired stereo
output results.
• Legacy Filter and Reverb effects are stereo.



Some Notes On the original Reverbs and Wahs in Helix.


Digital Igloo on The Gear Page


June 12th 2015

At launch, all reverb models are based on HD models, but rebuilt in HX. They sound notably better in Helix tho'. Eight of the ten wahs came from HD as well. All other FX models were created from scratch in HX.



july 2nd 2015

We felt that two HX wahs weren't enough, and the eight HD wah models were fairly simple to rebuild in HX (unlike models in other categories).




April 8th 2016

The only reason we ported 8 out of 10 wahs and the reverbs from HD (everything else is built from scratch in HX) is because we simply ran out of time. Ideally, everything in Helix would've been brand new. I'm not morally opposed to porting M-Class/HD models to HX, but we'd much rather make new stuff.




The 2 HX wahs -


UK and Teardrop.


BenAdrian -  TGP



Digital Igloo - TGP


The Reverbs and eight of the ten wahs are HD models rebuilt within the HX engine. We also rebuilt Doom, Epic, and Elektrik, but they're favorite custom hybrids that, IIRC, utilize some HX components—will have to confirm?
