The six Original Amp Designs in Helix/HX 3.70 (Clarity, Aristocrat, Carillon, Voltage, Kinetic, and Oblivion) are taken from Line 6's popular line of Catalyst guitar amps. Each boasts a unique, integrated boost circuit optimized specifically for that amp. You can assign the Boost parameter to a stomp switch:
Amp/Preamp > Line 6 Clarity, Original Amp Design inspired by classic clean solid-state and tube amps. Lots of clean headroom with just a touch of overdrive at the very end of the Drive knob's range.
Amp/Preamp > Line 6 Carillon, Line 6 Original inspired by modern and vintage versions of a popular EL84 driven tube amp with added grit at higher gain settings. We kept the good quirks and eliminated the ugly ones, while also making the tone controls more flexible.
Amp/Preamp > Line 6 Kinetic, Line 6 Original where all the preamp stages clip at roughly the same time, allowing the amp to go from mostly clean to heavily distorted using the guitar's volume control.
Oh man, this one is fun with a capital Ffffff but you'll want to read up on how to get the best results. Works best as one of the first blocks in your signal flow. NOTE: Feedbacker loads bypassed by default.

Helix/HX's new cab engine (introduced with 3.50) makes it easy to quickly find a great cab sound by automatically phase and time-aligning the mics in dual cab setups; this avoids the phasing or "thinning out" that can occur naturally when using two mics at different distances. However, some studio engineers are very adept at using phase misalignment to achieve interesting sounds. We've now added a new "Auto" value to the Cab > Delay parameter (all the way left, before 0.0 ms) that automatically approximates the delay through the air when changing the mic Distance parameter.
"The Grammatico GSG100 is an amp based on the study of legendary amps made around 1980. This model aims to capture all the unique details of this amplifier circuit, many of which are quite different than popular guitar amps from the major companies. The GSG100 is a feature-rich and complicated amp. There are many amazing sounds in the amp; however, the controls allow for such a wide range of adjustment that it's possible to get unpleasant sounds from it as well. To best use the amp, it really helps to know exactly what each of these features is doing to the guitar signal. Let's go through the parameters as they are found in the Helix model:"
"The Line 6 Elmsley is a new Line 6 original amplifier that employs a parallel distortion topology that layers distinct saturation characteristics across the lower and upper registers. The Elmsley features a smooth and present bottom end with some exceptional sparkle and definition all through the midrange and above. The result is an amplifier that is dazzling across the full spectrum, and the amplifier deals with pedals in spades.
Amp/Preamp > PV VitriolCrunch, based on* the crunch channel of the Peavey Invective (Master boost off). Peavey designed this 6L6 tube-powered monster in collaboration with Misha Mansoor of Periphery, with the goal of offering no-compromise, high-gain performance and flexibility.

3.50 renames the Impulse Response > Mono subcategory as "Single" and adds a new subcategory: Dual. The IR > Dual block can accommodate two 1024-point IRs, you can pan them independently, flip the polarity of either one, and even slightly delay one vs. the other to account for any phase inconsistencies between IR developers.
Due to further improvements to Helix Core, new Cabs and 1024-point IRs use roughly 66% less DSP as in 3.15 or earlier. Even the new IR > Dual block uses less DSP than a single IR block in 3.15. 2048-point IRs use roughly 80% less DSP, although they still use a lot of memory, so they're still limited to one instance per path. NOTE: Older Hybrid cabs use the same amount of DSP as in earlier firmware.
Before updating Helix Native, it is highly recommended that you export a bundle and/or export all of your setlists. This is done by going to Settings (the gear icon in the bottom left of the window), the Presets/IRs tab, and clicking Export Bundle. Some hardware compatibility modes (HX Stomp, HX Stomp XL, HX Effects) do not have this feature as they only have one setlist. In these modes, the setlist or presets will need to be exported instead of a bundle.
