Yamaha TX-81Z

4 Operator FM multi-timbrel synth module, has some classic low end bass sounds and many other DX-7 like sounds. Has less operators than the DX-7 but more waveforms, that is more than just sine wave. Like all rack synths many people don't like to program it from the front panel because of the fiddley buttons and small display. There is a map of the menu that slides out from the lower section of the  rack unit that makes operating it from the buttons and LCD easier, after a while you know where all of the parameters are "off by heart". Some people can't get their head around the FM way of modifying sounds. If you want original FM sounds you have to play with it a bit. It has no drum samples. The built-in effects consist of some midi echoes and other midi effects (that I have never used). Mine is a us import and requires a clunky adapter to get it onto 250 V power.

Sounds

Great sub sonic bass sounds, the classic post 70's R+B electric piano and bass sounds. Many stinging and bubbling FM sounds. The usual FM metallic bell and vibe sounds. Dose the drum and bass sine wave bass with that extra bight. It can't make the classic warm analogue sound. It makes its own analogue like sounds that great in their own tight way. It has a family of piano like sounds that have their own unique and wonderful nature but don't expect a Steinway. It makes some pretty rippy and ravey hard sounds. Accused by some of being a bit thin. Has a layer feature that allows you to put all of your 8 synth modules on the same channel that give it a pretty fat effect. The drum sounds that can be made by the normal synth section can make some wonderful extra percussion effects but are no substitute for sampled drums unless you want something really arty.

Relations

It is a rack version of a DX-100. Is superior but related to the DX-21 DX-9 DX=27 and it is a smaller multi-timbrel cousin of the DX-7.

 

Pro

  • Multi timbrel.

  • Can be layered to create really complex wide sounds.

  • Lots of classic FM and useful presets.

  • Pretty cheap on the second hand market.

Con

 

  • You have to learn how to program it if you are used to massive banks of knobs.

  • Only 32 user patches, you have to compensate this by using a patch librarian, I have heard of 3rd party memory expansions.

  • No real drum sounds.
