TR-909 Rhythm Composer
Made in 1983

TR909 RHYTHM COMPOSER is a programmable drum machine
with 96
rhythm patterns can be memorized-48 patterns in each of two banks.
There are two banks, each having four tracks for
storing programmed rhythm chains of up
to 896 measures.
Eleven kinds of sound sources-Bass Drum, Snare Drum, Low Tom,
Mid Tom, High
Tom, Rim Shot, Hand Clap, Closed and Open Hi-hat, and Crash and
Ride Cymbals.
Several controls such as Tune or Level are provided for each sound
sources. You can
accurately tailor their sound. A Shuffle function and Flam effect
are also provided to create
full variety of drumming.
There are two loading modes. In the real-time mode, you can create
rhythm patterns by
tapping the sound source buttons to the rhythm. In the single-step
mode, you can program
a rhythm pattern by writing each sound source in the each step.
The same as with the
TR-808 and TR-606 rythm machines.
A large LED display indicates the measure number and tempo in
numerical number.
A tape interface is provided for data storage on cassette tapes.
In addition to the Master Output, each sound source
can be outputted separately
using Multi-Output jacks.
Three MIDI jacks are provided-two for output and
one for input. They allow the
TR-909 to be connected with other MIDI devices to synchronize
or to use external
sound sources. Or, the TR-909 can be controlled by the device
connected to it.
This allows you to create complex, sophisticated drumming. The
TR-909 has a
5-pin DIN Sync jack for synchronized performance. It can be started
or stopped
by the optional DP-2 foot switch. It also generates the Rim Shot
trigger to control
an external device. The use of an M-64C RAM cartridge (available
from Roland)
doubles the memory capacity of the TR-909 for the rhythm patterns
and rhythm
chains.
