Helix Py API

Unofficial API for managing Line 6 Helix files and related devices

Overview

Helix-py-api is the unofficial API for managing Line 6 Helix files and related devices. It includes features for editing, standardizing, importing/exporting, renaming, reordering, and cloning bundles, setlists, presets, and snapshots. You can easily build setlists and presets from separate files as well as breakup bundles and setlists into individual setlist and preset files. It also includes simplified MIDI control (i.e. no MIDI message format/value knowledge needed) for Helix hardware and software (Helix Native) as well as direct MIDI control for other Line 6 (ex. FBV) and 3rd party devices.

Helix-py-api will open up a new world of possibilities. Here are a few ideas to get you started:

Automatically change to a specific setlist, preset, and or snapshot with one click (i.e. script, button, etc) ex. Change on your Helix, your co-guitarist, your bass player, or all at once Cleanup all your setlist, preset and snapshot names: ex. Uppercase, no special characters, etc ex. Change "Lead" to "Solo", "New Preset" to "" Standardize snapshot colors (for every preset in every setlist) to your desired criteria (ex. SOLO=red, CLEAN=WHITE, etc) Easily mass import a ton of presets into a single setlist ex. After you downloaded bunch of presets from CustomTone Individually backup all your presets to Github

Notable Limitations

Until time, knowledge, and desire permits to add new features, below are some notable limitations.

Helix

• Reading state/changes directly from the Helix
• Importing/exporting files to/from the Helix
• Anything not exposed in the API (ex. blocks, IRs, favorites, etc)

Helix Native

• Controlling Helix Native requires a virtual MIDI cable: https://springbeats.com/2016/12/10/springbeats-free-virtual-midi-cable/
• Helix Native midi control through VST's is severely limited as stated in the Helix Native product manual: AU and AAX Plugin Formats Only: At this time, remote MIDI control of setlist and preset changes is supported only with the AU (Mac) and Pro Tools AAX (Mac and Windows) Helix Native plugin formats. It is not supported for the VST2 or VST3 Helix Native plugin formats on Mac or Windows.

Your contributions are greatly appreciated!

Getting Started

Download and install the API

git clone https://github.com/HackLabsGuitar/`Helix-py-api`.git
cd `Helix-py-api`
pip install -r requirements.txt

Optionally change any default settings.

Create an API instance.

import helixapi

helix = Helix()

This will load a default empty bundle template. You can instead load your own bundle:

import helixapi

helix = Helix(file_path="/path/to/bundle.hlb")

Usage Examples

The full API of this library can be found in the API reference.

# Example: Import/export files
helix.setlists[1].import_setlist(file_path="/path/to/setlist.hls")
helix.bundle.export_bundle(file_path="/path/to/bundle.hlb")

# Example: Import multiple/export to individual files
helix.setlists[4].presets.import_presets(file_paths=["/path/to/preset1.hlx", "/path/to/preset2.hlx"])
helix.setlists.export_setlists(file_path="/path/to/setlists")

# Example: Change properties of a setlist, preset, or snapshot
helix.setlists[0].name = "Setlist 1"
helix.setlists[1].presets[0]. = "Set2-Pres1"
helix.setlists[0].presets[0].snapshots[0].name = "Snapshot 1"

import helixapi.snapshot.LEDColor as LEDColor
helix.setlists[0].presets[0].snapshots[0].ledcolor = LEDColor.RED

# Example: loop through items
for setlist in helix.setlists:
    print(setlist.name)
    
    for preset in setlist.presets:
        print(preset.name)

        for snapshot in preset.snapshots:
            print(snapshot.name)

# Example: standardize setlists, presets, and snapshots
helix.setlists.standardize()
for setlist in helix.setlists:      
    setlist.presets.standardize()
    for preset in setlist.presets:
        preset.snapshots.standardize()
