Roland adds another classic drum machine to its product line.

The release of Roland’s AIRA, a series of emulated digital synths, was one of the year’s biggest stories. Now, following takes on the legendary 808, 909 and 303 machines, Roland has turned its attention to the TR-707 — a staple of early house and acid records — and the Latin-flavored TR-727.

Every sound from the two machines, along with new and modified 808 and 909 sounds, will be released as part of a TR-8 expansion pack, available on December 19 for $95.

Watch videos about how the module was developed and see it in action below. As important as they were, the 707 and 727 are on the outside looking in of our list of synthesizers that shaped modern music. [via RA]
