Roland today introduced the TR-707 and TR-727 Software Rhythm Composers, the latest in their Legendary series of software-based virtual instruments available via Roland Cloud.

The pair of virtual instruments use Roland’s Analog Circuit Behavior (ACB) technology, which models the behavior of the individual components of the original circuits.

Here’s what Roland has to say about the TR-707 and TR-727 Software Rhythm Composers:

“In 1985, Roland introduced the now-famous TR-707 and TR-727, the company’s first drum machines with all sounds based around PCM samples. The TR-707, with its orange livery, had the most advanced pattern sequencing capabilities to date and included 15 punchy drum sounds covering all the basics, from kick and snare to toms and cymbals. Its sibling, the blue-highlighted TR-727, was an all-out percussion powerhouse with 15 Latin-inspired sounds that could take any groove to new heights. Each unit was formidable on its own, but together they were unstoppable.

Taking their rightful places next to other classics in the Roland TR series, this dynamic duo of drums and percussion has appeared on hit tracks in many genres through the years, including synth-pop, acid house, industrial, electro, indie, alternative, and more. The software-based recreations reproduce their sound and behavior with 100-percent authenticity, coupled with modern upgrades that take them into all-new creative territory.

The playback engines in the TR-707 and TR-727 were primitive by today’s standards, with 25 kHz sample rates and 8-bit resolution (and even 6-bit for some tones). To optimize performance, Roland engineers used short PCM waveforms with decay introduced later in the analog circuitry. But this early hybrid approach had its limitations, with deviations in the digital clock and analog circuitry causing variances in the pitch and decay characteristics. This combination of factors strongly contributes to the charm of the TR-707 and TR-727 and their unique and pleasing lo-fi punch. To replicate these behaviors in software, Roland started with the original PCM wave data from the hardware. Next, ACB technology was used to recreate the interaction between the PCM engine and analog output stages, carefully including all its quirks and instabilities.

The software-based TR-707 and TR-727 also include many updated features inspired by popular aftermarket modifications. Users have deep levels of sound control unavailable with stock hardware units, including attack, decay, and tuning for individual sounds, the ability to overdrive the internal circuitry, and much more. Additionally, the sequencer features include numerous modern enhancements for infusing grooves with added detail and nuance.”

Pricing and Availability

The TR-707 and TR-727 Software Rhythm Composers are available to now from Roland Cloud for $149 each, and are also included with the Roland Cloud Ultimate membership.
