Common questions about accounts, downloads, and how each tool works.
Browsing the tools and reading guides never requires an account. Some tools are open to anyone, and some require a free account to use or to download — each product card shows which applies before you commit to anything.
Everything currently on SubverseLab is free. Signing in with Google creates a free membership — no payment details are ever requested for any tool or pack listed today.
Where a tool applies a daily limit, the exact rule is documented on that tool’s guide. Subverse Mix Check allows members one completed analysis per IP address per UTC day; verified admins have no product quota. The website passes membership into the tool, so the tool does not show a second sign-in screen.
It shouldn’t. Opening a member-gated tool from its Launch button on SubverseLab passes your session to the tool automatically. If a tool still asks you to sign in separately, that’s a bug — please report it using the link below.
Free access and free downloads are two different gates. A product can be fully public to look at and even use, while its actual download is reserved for signed-in members — this is stated on the product card itself, next to the download button.
Use the “Report Broken Link or Technical Issue” button on the tools page, or email info@subverselab.com directly.
Standard MIDI drum patterns — not audio. You pick one of 22 genre styles and Sensei writes an 8-bar, 4/4 pattern across six drum channels: kick, snare, hi-hat, open hat, crash and perc. Tempo comes from the style and the seed is drawn fresh each time, so both are shown as readouts rather than fields you fill in. You export a .mid file and load your own kit or sampler in your DAW.
Yes — kick, snare, hi-hat and perc each have a density knob that thins the pattern already loaded, removing the least structural hits first. The knobs take effect while playback continues and never start a new generation, so you can shape a groove by ear without losing it. Variation is the separate control: it derives another take from the same pattern at the same style, tempo and seed, and leaves locked channels untouched.
Full Pattern gives you one .mid containing every channel. Every Channel gives you a .zip with one .mid per channel. A single channel on its own is the Channel MIDI button on that channel’s mixer strip. Exports follow what you are actually hearing, including your density settings; mute and solo affect playback only and never remove notes from the file.
No. Your WAV or MP3 is analyzed from temporary storage and deleted after processing; only the measurement result is returned. The tool reports direct loudness, level, spectrum, and supported mono fold-down evidence. It does not invent a quality score, key, BPM, or AI recommendation.
Members get one completed analysis per IP address per UTC calendar day. Failed or undecodable files release the reservation. Verified SubverseLab admins are exempt from the product quota. Membership is handed over from the website; Mix Check has no separate login.
On SubverseLab’s own server. The Splitter became a web tool in August 2026, replacing the desktop app that ran separation on your machine — so the honest answer changed with it: your file is uploaded, separated in a dedicated Cloud Run service, and held in that instance’s temporary workspace only until you have collected the stems. Completed jobs and their audio are discarded within about thirty minutes, and nothing is written to the product database. Key and BPM analysis is unlimited; separations are one per member and per network address each day.
SynthPulse writes melodic and bass patterns; Sensei writes drums. SynthPulse gives you a 16-step pattern across six lanes — four lead, two bass — in one of four styles, and exports it as MIDI. The sound you hear in the browser is a preview to help you judge the idea; the exported file carries notes only, and your own instruments decide how it sounds.
It is the ranking model’s prediction, from 0 to 100, that a pattern is one somebody would keep. Generate writes several candidates, rates them and hands over the best. The model learns from exactly one signal — which patterns members download — so downloading a pattern is what teaches it. Editing a pattern by hand clears the score rather than recalculating it, because the score belongs to what the tool proposed and you have since changed it.
No. It is a calculator and it runs entirely in your browser — no upload, no server processing, no account. Enter a tempo and it returns delay and reverb times, note-to-Hz harmonics and sample repitch math, and you can hear each value before you use it: it plays a real echo at that division, a synthetic reverb tail at that decay, or a tone at that frequency.
No. It’s built for ideation, not project storage — a generated idea can be downloaded as a one-time recipe file, but nothing is saved on SubverseLab’s side.
