Where the facts come from. Every spec, feature tick and claim comes from the maker's own page, a store listing, a manual or a retailer's spec sheet, read on 2026-10-07, and the exact words relied on are kept with each row (open "Sources" on any card). Store ratings and review counts, where an app exists, are the stores' own on that date, pulled through Sonar, an app-store analytics service. A feature is marked yes only when one of those sources says it; when none does, it is shown as unknown rather than as no.
How it was checked. Every row was researched once and then handed to a second, independent pass whose only job was to break it: open the same pages, check every spec, every tick, every rating and every quote. Rows it could not confirm were corrected, marked unknown, or dropped before publishing.
What this page does not measure yet. Accuracy. Every accuracy figure in the table is the vendor's own claim, quoted, and vendors measure on their own test songs. We have not run the same recordings through every tool and counted the wrong hits; when we do, the method and the songs will be here. In the reviews we have read, the common experience is a usable draft that needs correcting, better from a drums-only track than from a full mix.
Prices. Every price is in US dollars, read on 2026-10-07 on the store or page named next to it, with a link: Sweetwater, Musician's Friend or the maker's own store for gear and books, the US App Store's in-app purchase list or the maker's pricing page for apps. When a maker sells for less on its own website than in the app, both are shown. Prices change, so the date is part of the fact: check the store before you buy. Nothing on this page is an affiliate link.
Photos. Product photos and icons belong to their makers and publishers, taken from their own pages to show which product a card is about. Each card names its source; a maker who wants a photo removed can write to support@upbeat.studio.
