Line 6 released Helix Stadium 1.4, a free firmware update for its multi-effects processors, on October 13, 2026. The update supports the Helix Stadium XL Floor and Helix Stadium Floor amp and effects processors1.
The new Showcase stem separation feature lets players isolate parts from an audio file, then mute them to practice or perform alongside the remaining tracks. Users import an audio file through the Helix Stadium app and use the cloud-based separation service to create five stereo stems: drums, bass, guitar, vocals and other. Individual parts can be soloed for closer listening when learning a song, and players can mute the original part and play it themselves over the remaining stems1.
The three new Agoura amp models are the Brit SL100, based on the Marshall Super Lead from 1967, 1968, 1970 and 1971, with Normal, Bright and Jumped channels available for each era; the Omega Granophyre, based on the Omega Ampworks Granophyre 6L6; and the Prosecutor, a Line 6 Original Agoura amp inspired by the Litigator1.
The six effects comprise four distortion models and two modulation effects1:
| Model | Based on |
|---|---|
| Mercator | Line 6 Cartographer amplifier preamp |
| Rock Box Boost | Z.Vex Box of Rock boost circuit |
| Rock Box Distortion | Z.Vex Box of Rock distortion circuit |
| PortaBox 424 | JHS Pedals 424 Gain Stage |
| Essex Vibe | Vibrato circuit in a Vox AC-30 |
| Dimension W | BOSS Dimension C DC-2W chorus |
Line 6 calls firmware 1.4 the "Eras Update," referring to the different versions of the Marshall Super Lead represented in the Brit SL100 model.
"We dubbed the 1.4 update the 'Eras Update' because our new Brit SL100 Agoura amp model lets you choose from four sonically different 'eras' during the evolution of the Marshall JMP 1959 Super Lead 100 head"
According to Line 6, firmware 1.4 significantly reduces preset load times. The Helix Stadium app gains tethered USB-C connectivity for editing on macOS and Windows alongside its existing Wi-Fi connection. MIDI control now extends to Matrix Mixer settings, and Showcase playback can automatically skip marked song sections. Other changes include nested folders for organizing Clones and the ability to convert effect blocks from mono to stereo while retaining their parameter settings; the release notes specify that switching between mono and stereo clears snapshot and controller assignments1.
The update is free and available through the Line 6 software downloads page. Line 6 also requires hardware users to install the latest Helix Stadium app1.
