INTRODUCTION
The TR-09 is a sound module that uses cutting edge modeling technology to faithfully model the Roland TR-909 drum
machine which went on sale in 1983. In addition to its compact size, it allows battery-powered operation and
contains a small speaker. You’ll be able to enjoy full fledged TR-909 sound anywhere.
•"The TR-09 can operate on batteries or on USB power. If you are using batteries, insert four AA batteries, making
sure that the batteries are oriented correctly.
•"If you handle batteries improperly, you risk explosion and fluid leakage. Make sue that you carefully observe all of
the items related to batteries that are listed in the “USING THE UNIT SAFELY” and “IMPORTANT NOTES” leaflet that
came with your machine.
•When turning the unit over, be careful so as to protect the buttons and knobs from damage. Also, handle the unit
carefully. Do not drop it.
•"When the batteries run low, the “btLo” blinks on the display. Replace the batteries as soon as you can and this
message will go away.
From the Roland Web Site regarding the TR-09:
The influence of the TR-909 drum machine is still heard—and felt—more than three decades after it was launched.
Now, the 909 sound is available as part of the Roland Boutique series in the form of the TR-09. Featuring the same
front-panel layout and user interface of the original, the TR-09 is powered by Roland’s ACB technology, delivering the
speaker-pummelling power of the TR-909 in a super-affordable and portable format. Offering precise control over an
array of drum parameters and the ability to keep playing when switching modes, the TR-09 may be compact, but it
still has the power to move people. Studio sessions are well catered for too, with four separate outputs via USB
audio, external instrument control via a trigger output, and USB MIDI.
909 Power via Roland’s ACB Technology
The original TR-909 blended analog kick, snare, and tom drums with six-bit samples for the hi-hats and cymbals. This
hybrid approach to sound generation meant that the 909 sounded like no other drum machine. Accurately recreating
such an influential sound while retaining the ability to edit and tweak the various parameters is only possible via
Roland’s ACB (Analog Circuit Behavior) technology, which is also found in the popular AIRA series.
Connect with External Gear
The TR-09 is designed to easily connect with other gear. The main stereo mini-jack output can also be reconfigured
to send the selected instrument to the right channel, with the other instruments output to the left. A mix input routes
external audio through the main outputs, while the trigger output lets the TR-09 drive vintage analog synths such as
the SH-101 or JX-3P, or modern gear like the current SYSTEM-500 modular series. Sync and control other gear via
standard MIDI ports or USB, and even send the audio of four individual drum parts via USB to continue working in
your favorite DAW.
USB Audio Interface for Direct Recording to Your DAW
Via its USB port, the TR-09 also functions as a high-quality audio interface, providing a simple and reliable way of
recording directly to your DAW application. You can even send individual drums to separate channels, thanks to the
TR-09’s four discrete outputs over USB. Saving your favorite settings and sequencer patterns is easy too via the USB
data backup function.
Classic TR-REC Sequencer with Enhanced Functions
Dedicated TR-909 users will recognise the classic TR-REC style of programming found in the TR-09, with a choice of
Step or Tap write modes. You can even change modes while the pattern continues playing, something not possible on
the original. The TR-09 sequencer has 16 steps, and each has 16 sub-steps so you can fine-tune your performances.
And just like the original TR-909, the Shuffle/Flam parameter can be selected using the buttons—but if you need
greater control, simply use the display and rotary encoder to perfect your pattern.
Battery or USB Bus Power
Some of the best music is made away from the studio, so the Roland Boutique series runs on 4 x AA batteries, ready
for when inspiration strikes. Alternatively, you can power the TR-09 with USB bus power.
