The Yamaha TX816 FM Tone Generator System basically consists of eight identical TF1 modules, mounted on a MIDI rack frame. This rack frame supplies the power to the TF1 s, and provides COMMON MIDI IN/OUT terminals so that all eight modules may be controlled by a single MIDI signal, or they may be controlled independently. The TX216 contains two TFls, mounted in the same MIDI rack frame, and you can easily install further TFIs into the TX21 6 whenever you like, with the possibility of building up to exactly the same system as the TX81 6. The tone generating unit incorporated into each TF1 module is equivalent to the one incorporated into the Yamaha DX7 Digital Programmable Algorithm Synthesizer, which has completely revolutionized the world of digital music.And, just like the DX7, each TF1 contains a memory bank which can store the data of 32 different 1 6—note polyphonic voices. However, these compact modules are actually more sophisticated than a DX7, because, as well as being able to store the 145 parameters relating to each voice, they can store 25 function parameters, for effects such as portamento, glissando, modulation wheel setting, and so on, which can be individually set for each voice. All the voices and functions are available for editing and modifying, so that on the TX81 6 you can have 256 different voices, which can be considered as 32 sets (or “combos”) of 8 voices. This aligns particularly well with the Yamaha 0X1 Digital Sequence Recorder, which can store 32 banks (or "songs") each containing eight tracks of music data. Yamaha’s FM Digital Synthesis technique enables you to produce amazingly lifelike acoustic sounds, as well as the more "conventional" synthesizer tones. For the user, it requires a completely different approach to creating voices. There are no voltage controlled oscillators, amplifiers or filters (VCOs, VCAs or VCFs). An entirely unique tone generating technique is used, employing six sine-wave "operators", each with an envelope generator, that can modify each other in billions of ways to produce the complex, moving structures that are characteristic of any acoustic sound. A full description of FM Digital Synthesis is given in the DX series systhesizer owner’s manuals. All the voices in the TF1 modules are controllable using MIDI signals from the DX series synthesizer, the KX series Remote Keyboard, the 0X series Digital Sequence Recorder, or the Yamaha CX5M Music Computer. MIDI instruments made by other manufacturers may also be used to control the TX81 6, but editing voices is only possible with the Yamaha DX7,DX5 or DX1 synthesizers. Through the use of state-of—the-art microcomputer circuitry, the wide range of functions can be controlled by just three buttons mounted onl the front panel of each module. Each of these buttons fulfills a variety of functions, and together they control all the sophisticated circuitry incorporated into the TX816 and TX21 6, with ease and efficiency. A superb example of Yamaha's aim to make state-of-the-art digital music technology available to all. The TX816, and all Yamaha's digital instruments, are MIDI compatible, and may be joined together in a variety of configurations so that each unit may either drive, or be driven by, the others. As the name suggests, digital music instruments convert all musical information into numbers, which are easily handled by computer circuits, and easilytransmitted from one device to another. Using extremelysimple connections, highly powerful digital music systems may be easily assembled. There are four basic modes of operation-- Play, Edit, Store and Utility. These are selected by pressing the selector button on the front panel of each module. This button is also used to select the sub- modes, of which there are 14. The LED Display on the front of each module shows you at a glance which mode or sub-mode the TX81 6 is using.


Your favourite DX7 revision?

which do you favor? DX7 original style DX7II/D/F DX7S TX7 TX816 TX802 obviously a lot of the revisions add the extra layering that makes them really worth hunting down, but do you prefer the sound of the original etc etc etc which is easiest to program?

...DX27, DX21 or DX100 for those who want something a little more usable, a DX1 if you're rich, or a TX816 for the psychotically insane with way to much time on their hands. There are plenty more to chose from 2)Go through the presets marvelling at the brilliance of 'Solid Bass' and 'Pluck Bass' 3)Think to...

Why FM? (Yamaha style)

...something different though and it had limited programmability from the front panel. Tg77 is box version of sy77. There was also the tx816 which had several full blown dx7s on cards. At least that’s what I seem to recall.
