Notes 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 TF1s, 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 TF1s, mounted in the same MIDI rack frame, and you can easily install further TF1s into the
TX216 whenever you like, with the possibility of building up to exactly the same system as the TX816.

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 16-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 TX816 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
QX1 Digital Sequence Recorder, which can store 32 banks (or "songs") each containing eight tracks of music
