Modeling the analog envelope and amplifier stages that came after the D/A converter allowed us to implement tuning, decay, PCM clock adjustment, and other parameters available in the plugin but not present on the original unit. To replicate its sound in software, we started with the original PCM wave data found on the classic machine, then used our advanced circuit modeling to completely recreate the PCM output stage, carefully including all of its quirks and instabilities. And though the TR-727 lacked the ability to edit sounds, the combination of these factors ultimately led to it being highly sought after for its iconic sound and infectious groove.Įven though the TR-727 was primarily a digital device, it’s impossible to perfectly capture its unique sound using samples. Furthermore, deviations in the clock and the analog circuitry downstream of the D/A converter caused variances in the pitch and decay characteristics. These low bit rates caused quantization noise during the sound’s decay, so non-decaying PCM waveforms were used, with decay introduced later in the analog circuitry. It’s a classic to this day because even with its limited palette and no sound editing capabilities, it’s one of those things that “just works.” And while this software recreation nails that vintage vibe, it introduces tuning, decay, and other manipulations that make the creative possibilities bloom.ĭeveloped in the mid-1980s, the TR-727 had a 25 kHz, 8-bit (or 6-bit for some tones) sample playback engine that was primitive by today’s standards. The blue-highlighted TR-727 could take any track to new heights with its 15 Latin percussion-inspired sounds and powerful sequencer. However, after the TR-909’s release, Roland embraced the trend towards digital technology with a Latin percussion machine that combined sampled sounds with the user-friendly TR interface-newly enhanced with the hands-on immediacy of individual faders. Memory chips and digital-to-analog converters were costly at the time, so there was concern that an all-digital design would make the product unaffordable for many musicians and would have limited sound shaping options. Thanks to our Analog Circuit Behavior (ACB) technology, you can now have the authentic sound and experience of this classic percussion machine right inside your DAW- with modern upgrades that take it into all-new territory.īefore the TR-727, Roland released the now-legendary TR-909, which was developed as an analog-digital hybrid rather than a fully digital device. And it’s perfect for afrobeat, reggaeton, and other more exotic contemporary styles. Lesser known but no less loved, the TR-727 found its way into a wide range of styles over the decades, from tribal and acid house to pop and techno.

In 1985 Roland released the TR-727 Rhythm Composer-the Latin percussion packed sibling of the now-famous TR-707.
