Roland TR-8S: Rhythm Composer for the Modern Producer

Music has been a constant presence throughout human history, and with it, the tools to create and manipulate sound. One such tool that has made a significant impact on modern music production is the Roland TR-8S Rhythm Composer. In this article, we’ll delve deep into the features and capabilities of this device and why it stands out in today’s production landscape.

Roland: A Brief History

The Roland Corporation has long been a pioneer in the music industry, with groundbreaking instruments that have shaped various genres. Their TR series, particularly the TR-808 and TR-909, have left indelible marks on genres like hip-hop, techno, and house. Their signature drum sounds have been emulated and sampled countless times.

Fast forward to today, the TR-8S is Roland’s homage to the legacy, melding the classic with the contemporary.

Connectivity & Hardware

  • Outputs: The TR-8S provides eight separate analog outputs, supporting individual sound processing. This is complemented by high-quality 24-bit/96 kHz digital-to-analog converters.
  • External Integration: The drum machine includes a dedicated trigger output and stereo audio inputs, widening its utility both in the studio and onstage.
  • Interface Capabilities: Beyond its drum machine functionality, the TR-8S doubles as a multi-channel audio and MIDI interface. It facilitates seamless MIDI and audio transfer via USB.
  • Software Integration: Roland’s TR-EDITOR complements the TR-8S, allowing users to design and manage patterns and kits on a computer.

Design & User Experience

  • Ergonomic Layout: One of the striking features of the TR-8S is its ergonomic layout. Buttons, faders, and knobs are positioned intuitively, making it easier for both new users and seasoned pros to navigate the system. This thoughtful placement not only speeds up the workflow but also reduces the learning curve for newcomers.
  • Visual Feedback: The integration of RGB color faders and TR-REC buttons is more than just an aesthetic choice. These elements provide immediate visual feedback, signaling what’s active, muted, grouped, and more. This clarity is particularly beneficial during live performances, ensuring that the producer remains in control and is informed of the ongoing processes.
  • Material & Build: The TR-8S exhibits a sturdy build quality. The tactile response from the buttons and knobs feels reassuring and indicates that the machine is constructed to withstand regular use, be it in a studio or on the road.
  • Customization: The machine allows users to customize the brightness, glow, and color of its elements. Beyond the obvious visual appeal, such customization can be used functionally to categorize and identify specific sounds or patterns quickly.
  • Aesthetic Appeal: Without compromising functionality, the TR-8S has a sleek and modern appearance. Its color palette is understated, making it fit seamlessly into any studio setup. A notable feature is the ‘lava lamp mode’, which, while whimsical, adds a touch of playful dynamism to the device.
  • User-Friendly Interface: Feedback from users indicates that the TR-8S offers a user-friendly interface. The large display, coupled with clear labels, simplifies the task of accessing and modifying sounds or patterns.
  • Backup & Portability: The inclusion of an SD card slot is a testament to the machine’s user-centric design. This feature ensures that users can backup their entire setup and, in case of any mishap or when shifting to another TR-8S unit, can restore their configurations effortlessly.

Features and Functionality

  • ACB (Analog Circuit Behavior) Technology: Central to the TR-8S’s sound is Roland’s proprietary ACB technology, which meticulously replicates the nuances and intricacies of classic Roland instruments. Instead of simply relying on samples, ACB provides a digital emulation of the entire analog circuitry, capturing the unique character and tonal quality of the original hardware. This technology is instrumental in recreating the sounds of iconic drum machines like the 808, 606, 909, 707, and 727.
  • Versatile Sound Palette: Beyond the classic TR sounds, the TR-8S introduces FM sounds that are designed to push boundaries. These FM sounds range from ethereal, silvery drum hits to more esoteric, contorting sonic elements, all of which can be manipulated through a variety of parameters.
  • Hybrid Kits Creation: The TR-8S is not limited to preset sounds. Users have the flexibility to layer their own samples, either mono or stereo, with the onboard collection. This means that one can craft custom kits that blend TR, FM, and sampled sounds, yielding tracks that are both distinct and dynamic.
  • Detailed Sound Manipulation: The device provides deep control over the various sound elements. Users can adjust aspects such as tuning, decay, start points, and playback direction of samples. This level of granularity enables producers to fine-tune their tracks, ensuring that they sound exactly as envisioned.
  • Effects Suite: The built-in effects have been crafted with percussion in mind. Whether it’s adding reverb to specific instruments, delay on a rimshot, or overdrive on a kick, the effects are designed to enhance and elevate drum sounds. Each channel on the TR-8S comes with a customizable CTRL knob, streamlining the process of sound-shaping and providing real-time control during live performances.

Pattern Creation & Performance Tools

  • Step Sequencing: The TR-8S incorporates Roland’s signature “TR-REC” step sequencer, but with modern enhancements. This allows for intuitive and flexible pattern creation.
  • Performance Modes: Users can either program using the 16 TR-REC buttons or the velocity-sensitive pad. The machine supports live recording and offers tools like velocity, accents, and sub-steps to add nuance to drum patterns.
  • Dynamic Drum Programming: The inclusion of probability tools adds an element of unpredictability to drum patterns. Additionally, users can store up to 128 patterns, each with its variations and fills, promoting dynamic live sets.
  • Motion Recording: The TR-8S offers motion recording capabilities, enabling users to capture subtle shifts or significant tonal variations within their patterns.

Real-world Application

Dance Music Production

Electronic dance music producers have found a friend in the TR-8S. Its intuitive sequencing and iconic sounds are perfect for creating pulsating rhythms. For instance, techno producers often use its 909 kicks and hats to lay the foundation for their tracks, layering custom samples to bring a unique twist.

Sound Design and Film Scoring

Surprisingly, the TR-8S has also found a niche in sound design for films. Its vast sonic palette and effects allow sound designers to craft unique textures and rhythmic elements that can be layered into a film’s soundscape, adding depth and dimension.

Live Performances

The hands-on control and real-time sound manipulation capabilities of the TR-8S have made it a favorite for live electronic performances. Artists can manipulate patterns on the fly, introduce new samples, or tweak effects, giving each performance a unique flair.


The Roland TR-8S Rhythm Composer, while nodding to its historical predecessors, is very much a tool for today’s producer. Its melding of classic sounds with modern features ensures that it has a place in studios across the globe. As with any piece of equipment, it’s not just about the specifications but how artists and producers harness its potential. The TR-8S, with its vast capabilities, offers a canvas limited only by one’s imagination.
