Terms of use

TEK-660 · last updated 30 September 2026

TEK-660 is a hobby project: a browser player, editor and MIDI librarian for the BOSS DR-660 drum machine. By using it you agree to these terms.

Not affiliated with Roland

TEK-660 is an independent project and is not made, endorsed or supported by Roland Corporation. BOSS, Dr. Rhythm and DR-660 are trademarks of Roland Corporation and are used here only to say which machine the software works with. The sounds are recorded by the author from the author's own DR-660. If you are a rights holder and object to anything on this site, write to the address below and it will be taken down.

Use

Accounts and paid features

An account is optional. Some features may later need a paid subscription; its price and what it includes will be shown before you pay, and you can cancel it at any time, keeping access until the end of the paid period. An account used to abuse the site may be closed.

No warranty

TEK-660 is provided as is, without any warranty. It may change, pause or stop. When it sends data to your DR-660 over MIDI, it overwrites the machine's memory: keep a backup dump of your own data. The author is not liable for lost data or any other damage from using it, as far as the law allows.
