Resumen del manual
Among its many operating features is its ability to write and record thirty two percussive rhythms incorporating up to eleven different sounds plus accents. Each of these percussion sounds has its own level control for full mixing flexibility over the total sound, and each sound also has its own separate output so that it can be mixed or processed separately from the others. Programming of the Rhythms can be accomplished either in or out of real time by means of a Step programming method which basically breaks each beat down into a series of steps, which can be varied to suit the desired rhythm. Each beat (or quarter note), can be divided into 3, 4, 6, 8, individual steps so that rhythms can be written incorporating as small a division as thirty-second notes. Once the various rhythm patterns are written and stored in computer memory, they can be arranged to perform an entire composition's percussion track by means of a Compose function. The track can last up to 768 measures. The memory can also be used in individual increments of 64 measures each to play up to twelve different songs. Three separate Trigger Outputs allow the TR-808 to be connected to various digital sequencers, synthesizers or other such devices for synchronized control of sound. Other performance features such as automatic insertion of Introduction or Fill In rhythms as well as remote control over both this and the Start/Stop function expand the TR-808's uses into live performance in addition to its obvious applications in recording and composing music.

Front and Back Panel Layout 2 Control Descriptions___________________________________3 P0W6T On/Off Switch This push-On/push-Off switch controls the flow of A.C. power to the TR-808 Rhythm Composer. The power must be switched 'On' for the TR-808 to perform any function. The 'On' status may be verified using any of the various LED lights on the front panel. Mode Selector The MODE selector is the knob located in the extreme upper left hand corner of the TR-808 control panel, used for both programming and playing operations and for memory protection as described in the Basic Connections section of this manual. Moving clockwise from the lower left the MODE options include: PATTERN CLEAR, 1st PART, 2nd PART, MANUAL PLAY, PLAY, and COMPOSE. Rhythm Programming Modes The first three yellow color-coded positions relate to programming Rhythm Patterns into the TR-808. The boxed PATTERN CLEAR position allows any of the 32 programmed Rhythm Patterns to be wiped from the memory, preparing their memory positions to be reprogrammed. The actual CLEAR function is activated with the red CLEAR button located below the MODE selector. 1st part position selects the first section of individual measure to be programmed with rhythm information. If the rhythms you are programming are made up from 16 or less evenly spaced increments, the 1 st position may be used as a complete single measure by itself. The 2nd part allows the selection of the second section of an individual measure to be programmed with rhythm information. By combining the 1st part and 2nd parts with suitable PRE-SCALE information it is possible to write rhythms with up to 32 evenly spaced increments for writing complex or subtly flexible rhythms of virtually any time signature. The relationship of the 1st part and 2nd part sections of any measure is determined by the PRE-SCALE programming for that measure, as described in the Writing Rhythm Patterns section of this manual. Play Modes The MANUAL PLAY Mode allows you to play any of the 32 TR-808 Rhythm patterns as you would a conventional rhythm machine, with the addition of automatic switching for intros, and'fills. MANUAL PLAY and PLAY are the only two Mode positions that wili protect your programmed memories when the TR-808 is switched off or disconnected. . The PLAY Mode allows a selection of up to 12 independently programmed rhythm compositions to be played with a combined maximum memory of 768 bars. These tracks are selected by the INSTRUMENT/TRACK selector to the right of the MODE selector Compose Mode The Compose Mode position allows the 16 rhythms programmed into the TR-808 to be combined into compositions (Tracks) and programmed into any one or more consecutive memories selected by the INSTRUMENT/TRACK selector positions. To COMPOSE within any of the 12 memories, that memory must first be cleared using the red CLEAR button. The actual programming of the 16 available rhythms into compositions is done using the STEP buttons along the bottom of the TR-808. Instrument/Track Selector This 12 position selector serves a dual purpose. During the programming of Rhythm Patterns it is used to select which of the 11 different drum voices or the Accent is being prog...
