Limits and availability
Check project limits, phrase lengths, browser audio requirements and the automatic output processing.
Glob Studio edits and renders music in your browser. The available tools depend on signing in, music being enabled on the site, browser audio support and the limits of the current project.
Access and browsers
The Studio entry and Jukebox appear only when the signed-in music feature is available. Signed-out visitors do not get the Studio entry. If you cannot find it, sign in and check the Glob Social guide.
Studio needs Web Audio and AudioWorklet support to make sound. Export also uses the browser's offline audio rendering. A browser with ordinary audio-file playback alone may be able to play rendered listener audio without supporting the full editing and synthesis tools.
MIDI input needs Web MIDI and the browser's permission. Without it, use the computer keyboard and on-screen piano or drum pads. Studio does not provide a microphone recording or audio-interface input selector. Use your operating system and browser controls for the listening output.
Small screens can open the Studio layout, but some detailed modular controls depend on the wider inspector. The Grid reference explains which controls require more room. A responsive layout does not imply that a phone has the same audio-processing capacity as a desktop.
Song limits
| Item | Limit |
|---|---|
| Project duration | 20 minutes. |
| Project data | 256 KiB for a saved project version. |
| Tracks | 1–32. The last track cannot be deleted. |
| Effects on a track | 20. |
| Shared FX channels | 8. |
| Arrangement clips per track | 128. |
| Launcher columns | 1–16. |
| Launcher repeat lengths | 1, 2, 4 or 8 bars. |
| Track modulators | 8. |
| Modulation routes per track | 64. |
| Automation lanes per track | 16. |
| Points per automation lane | 1,024. |
| Project and track names | 80 characters. |
| Launcher column names | 32 characters. |
| Tempo | 50–220 quarter-note beats per minute. |
The size limit covers the whole musical project, so it can be reached before a separate note, module or lane-count limit. If an edit cannot be applied, Studio keeps the previous project and reports the refusal.
Phrase and recording limits
An ordinary editable note pattern has 32 sixteenth-note steps. The roll shows 16 for a one-bar launcher clip. A longer arrangement placement repeats the shared track pattern. A longer launcher repeat length does not expand the note-writing window.
Notes use MIDI pitches 0–127. An ordinary pattern or launcher clip can hold up to 10,000 notes, subject to the overall project-size limit. The note editor limits written lengths to 0.25–128 sixteenth-note steps. Live note recording rounds held duration to 1–32 steps and uses the first launcher clip's wrap reference. Read recording before recording a longer performance.
Modular processing limits
A Grid graph supports up to 1,024 modules and 4,096 cables in its stored shape, with nesting limited during compilation. Saved or packaged devices can meet stricter processing budgets than that stored shape allows. Increasing voices, unison, delay memory or spectral processing can make a patch too large to prepare even when its module count is small.
The modular audio engine permits at most four prepared spectral stretch processors, including processors retained while a sound graph is being replaced. A patch near that limit can fail a replacement that temporarily needs both old and new processing. Simplify the patch or stop playback before retrying it.
Voice limits belong to each instrument. The factory sources use 16 voices, except Granular Dust with four and Mono Bass with one. When all voices are occupied, another note can replace an older voice. There is no single 48-voice limit for the whole current Studio engine.
Read sampling, custom devices and performance for the limits of those specific tools.
The automatic output limiter
The song's master path includes compression followed by a limiter. The limiter reduces peaks above its −3 dB ceiling and releases the reduction afterwards. It operates on the left and right channels separately. This processing is part of ordinary song playback and export, rather than a device you must add yourself.
The audio engine also replaces invalid final sample values with silence and resets invalid processing state. A device performance display can report these interventions as output guards or state resets. Such guards do not mean the patch is working correctly; use them to investigate unstable processing.
The limiter does not choose a comfortable speaker or headphone volume. Listening level controls your Studio monitoring, and your operating system sets the output-device volume. Lower track and effect-channel levels when the mix is overdriving processing. Turning down Listening level is not a way to change the exported mix.
Saves and exports
Browser saves belong to that browser and account. They can be removed by clearing site data or by browser storage removal. Deleted projects remain recoverable only while their browser copies exist. Undo history is bounded and is not a permanent version archive.
The current engine refuses old v1 projects instead of converting them silently. The refusal explains that the original is kept unchanged. Start a new Grid project when you meet it.
Export provides 16-bit WAV at 44.1 kHz through the visible panel. Full song, loop and stem options require a Grid instrument on every track. Publishing has separate listener-audio preparation and rights controls; see publishing.
