Independence and trademarks
303_LINE is an independent fan project. It is not affiliated with, sponsored by, or endorsed by Roland Corporation, Behringer, Acidlab, Reverb, Ticketmaster, or any artist mentioned on the site. Roland, TB-303, TB-03 and all other product, company, and artist names are the property of their respective owners and are used only to identify the products and people discussed.
This site is an archive, not a shop
303_LINE does not sell gear or tickets. Gear is sold by the marketplaces and retailers it links to, and tickets are sold by Ticketmaster. Any purchase is a transaction between you and that seller, and their terms apply.
Third-party data
- Prices come from Reverb listings. They are sellers' asking prices, not sale prices, and they change quickly. They are not offers, appraisals, or valuations from 303_LINE.
- Tour dates come from the Ticketmaster Discovery API. Dates, venues, and availability can change or be cancelled. Always confirm details on the event page. Not every show is listed on Ticketmaster, so the list is not a complete tour schedule.
- Data may be delayed, incomplete, or occasionally wrong. Please check the source before you buy or travel.
The sequencer
The sequencer is an original synthesizer built with the Web Audio API in your browser. It is inspired by the TB-303 sound but is not Roland software and does not reproduce the original hardware exactly. Sound varies by browser and device.
Volume and hearing
Acid sounds can be piercing at high resonance and distortion settings. Turn your volume down before you press run, and raise it gradually.
Accuracy of the history
The history and gear descriptions on this site are summaries written for general interest, based on publicly available sources. They may contain errors or simplifications, and gear specifications and availability change, so please verify details before you buy.
Affiliate links and commissions
303_LINE does not currently earn commissions from links on this site.
No warranty
This site is provided "as is" for information and entertainment, without warranties of any kind. 303_LINE is not responsible for decisions you make based on its content.
