Guitarix vs Helix Stadium Native

Guitarix is free software that acts as a virtual guitar amplifier on Linux through the JACK Audio Connection Kit. Mono sound-card input passes through a main amplifier and rack section, which can be routed separately for stereo output via JACK. The rack contains more than 25 effect modules, including noise gate, flanger, phaser, and auto-wah. LADSPA and LV2 plugins can be added, and Guitarix is also available as an LV2 plugin suite for loading amps and plugins in a digital audio workstation. The project names Ardour and supports connection to Rackarrack or another JACK-aware host. It can process synths and other sound generators as well as guitar. The maker says a properly configured Linux system can process signals in no more than 10 ms. Guitarix is standalone software with an IR loader, licensed under GNU GPL version 2. It is listed for Linux and macOS; source can be built for BSD and MacOSX.

Helix Stadium Native is an amp and effects plugin that brings Helix Stadium hardware sounds and tone tools into a digital audio workstation. It runs on macOS and Windows in AAX, AU, and VST3 formats, and is not a standalone app. The product page lists 132 amplifier models with 152 channels, more than 260 effects models, and more than 60 speaker cabinet models. The full license lists 27 Agoura amps with 55 channels plus 111 HX amps, 46 cabinets, and 274 studio effects. Hype control blends between more authentic and idealized amp sounds, while Focus View provides contextual parameter controls. The plugin supports third-party cabinet impulse responses and Proxy clones, as well as presets and setlists from Helix Stadium and Helix Stadium XL and original Helix and HX products with firmware 3.50 or later. External MIDI controllers and software can control parameters and snapshots. A free Intro plan is available; the full license costs $399.99 as a one-time purchase purchase and includes a 15-day trial.
