Everything to get you playing, authoring, and unstuck — guitar, bass, MIDI, licensing, imports, note effects, and troubleshooting.

Connect your input.

Use an audio interface for fretted parts, or a MIDI device for drums and keys, then select it in settings.

Pick a song.

Choose a song from Library, or use Browse to download verified songs from the official ShredQuest repo.

Set up the selected part.

Use the tuner for fretted parts, Kit Setup for drums, or Keyboard Setup for keys before starting a run.

Press Play.

Follow the preview and live lanes, hit the notes, and use Practice Scope to loop a difficult section until it's tight.

Fretted parts

Guitar, bass, and other fretted charts use the selected tuning and listen for pitch during gameplay. Open the tuner from song details and wait for stable strings before a scored run.

MIDI drums

Drum parts use MIDI lanes. Pick your MIDI input, use Kit Setup to teach ShredQuest which pad belongs to each lane, or reset to the General MIDI-style default mapping.

MIDI keys

Keys parts use MIDI note input. Pick your MIDI device, open Keyboard Setup, and detect or set the playable range so the lane matches the keyboard you are using.

Difficulty and scope

Songs can offer Beginner, Intermediate, Advanced, and Pro difficulties. Practice Scope loops a chosen section instead of the full song, so you can put focused reps into the bars that trip you up.

Results and mastery

Runs show streak, best streak, accuracy, hit ratio, pitch lock (the detector confidently locking onto your note), grade, and best score where those metrics apply. Full-song attempts build mastery and progress over time.

Visuals and timing

Gameplay can show preview and live lanes, optional metronome, background video when the song includes one, and simplified visual settings for a cleaner practice view.

Create your own tracks

Shredit is the free browser editor for authoring fretted parts, MIDI drum lanes, and keys parts. Authoring is free; importing or playing those custom packages in the desktop app requires ShredQuest Full — unless the package is verified official repo content.

Open Shredit

Use Browse for official songs

Browse shows verified songs from the official ShredQuest repo. "Verified" means each package is signed with an Ed25519 key and checked against a SHA-256 integrity hash, so what you download is exactly what was published. ShredQuest Free can download and play official repo songs after that check passes.

Add community repos

ShredQuest Full can add community or external repositories by URL. These are user-hosted sources, separate from the verified official repo and not a centralized publishing service.

Import ZIP packages

Local ZIP/project imports require ShredQuest Full. ShredQuest Free keeps import controls visible but locked so existing custom content stays visible.

Review inspection logs

Before installing, ShredQuest checks layout, metadata, chart data, audio, album art, background video, duplicate state, and edition access. Blocking checks stop import; warnings explain what will be skipped or changed.

Update or replace songs

If a repo publishes a newer version, ShredQuest can replace your local copy. Duplicate and update prompts show when recorded mastery would be reset, and you can keep the existing copy instead.

Handle optional video

Some repo songs and packages include an MP4 background video. Browse shows the required download size plus optional video size, and imports can continue without video when needed.

Restore official content

If an official song is modified, outdated, or no longer matches the verified package, ShredQuest can restore the official copy from the official repo. Full does not bypass official integrity or app-version checks.

Locked content is preserved

Custom songs, external repos, custom tones, and local imports remain in your library when Full is inactive — they just aren't playable until your install has an active Full entitlement. Nothing disappears when you change editions.

Start from Guitar Pro

Import supported .gp, .gp3, .gp4, .gp5, and .gpx files. Shredit inspects the file, shows importable tracks, and can bring in fretted parts, drum lanes, and keys parts.

Manage song parts

Build multi-part projects, rename parts, choose the default part, duplicate or reorder parts, and keep each part's notes, lanes, or pitches together.

Shape the chart

Add sections, tag note difficulty, edit beats and durations, apply fretted note effects, quantize selections, duplicate notes, and preview the timing as you work.

Add media

Attach .ogg, .mp3, or .wav backing tracks, adjust backing alignment, review audio with preview playback, crop cover art, and attach an MP4 background video.

Save safely

Shredit saves recovery drafts in the browser and offers them when you return. Save Project exports a ShredQuest ZIP package with project.json and resolved media.

What is included in Free?

ShredQuest Free can play built-in content and verified songs from the official ShredQuest repo. Custom songs, custom tones, external repos, and local imports require Full.

What does Full unlock?

ShredQuest Full unlocks custom songs, custom tones, external repos, and local imports for the shredquest-1 product line, including future 1.x updates.

Steam or direct Full?

Steam builds use the ShredQuest Full Upgrade managed by Steam. Direct license-key builds use Settings > Edition. Both unlock the same Full feature set when active.

Activation limit reached?

Each direct Full license allows 3 active devices by default. Email support with your license email and the masked key suffix shown in Settings > Edition.

Need a support reset?

Support can reset only local direct-license identity and activation state. Songs, tones, repo settings, progress, and normal app settings should stay in place.

Imported note effects can appear above gameplay notes. These markers are visual guidance only and do not change scoring.

No input detected?

Check Audio settings, your operating system input permissions, interface input gain, and the selected MIDI input if you are playing drums or keys.

No sound?

Confirm your output device, mixer level, model selection, and whether your interface is selected by the system.

Notes feel inaccurate?

Tune again, lower background noise, check your input level, make sure the song tuning matches your instrument, and calibrate the noise gate if pitch detection is unstable.

MIDI notes do not match?

For drums, open Kit Setup and remap the lane that is wrong. For keys, open Keyboard Setup and detect or set the playable range for the selected MIDI device.

Repo sync failed?

Check the repo URL, network access, and the repo's current status in Content settings. Official repo integrity failures should be reported with the visible error text.

Visuals feel sluggish?

Enable Simplified Visuals in Game settings and close GPU-heavy apps before long practice sessions.

Import failed?

Review the inspection log. It usually explains missing files, unsupported package shape, Guitar Pro track limits, validation issues, duplicate state, unresolved media, optional video problems, or whether the import requires ShredQuest Full.

Need deeper debug details?

Open Diagnostics in the desktop app and include the visible system status, selected model/tone, input/output devices, repo or package name, and exact error text when contacting support.
