Yamaha TX7

Yamaha TX7 Image

The TX7 is essentially a non-rack-mountable desktop module form of Yamaha's DX7 FM synthesizer. Editing can not be done from the front panel, but must be accomplished externally via MIDI using either a DX7 keyboard, the PR-7 programmer or a computer. Software such as Unisyn can be used to edit the parameters of the TX7. There are only 32 patches for storing any sounds as on the DX7. It's probably better to collect patches from the internet to expand your library of sounds since FM patch-editing is difficult enough on a professional DX synthesizer. Aside from its limitations, the TX7 is an affordable way to get your hands on original DX7 sounds. It has been used by Genesis, Human League and the producers behind the Spice Girls.

I had this one few years back. Not so cool, really hard to program and it's not even rack version. I use FM8 software these days - much more programing posibilities (filters, effects...) plus is compatible with DX7 patches.

Got one in the mail today. Sounds exactly the same as the DX-7 I ditched a few years back in favor of a Juno. So glad to have the sound back. Sure I'll miss the DX-7 keybed (perhaps my favorite keybed ever) but having such a big thing that I couldn't program wasn't worth it. I'll probably just use this thing with pre-made patches from online, but there are plenty of editors. CTRLR.org has a free panel.

About 20 years ago, I bought a used TX-7. If I remember correctly, it came with a multi-pin to mini (mono) cable and a cassette of (extra?) Yamaha factory presets.

commodorejohn, any sane synth or other audio device w/ a DAC will have a filter to remove aliasing & unwanted high freqs. It's called a reconstruction filter. You don't have to go far to find this out.

Totally irrelevant & unrelated to filters as used in synthesis, famed for being configurable & controllable in real time.

The LPF on the outs is fixed, hopefully at a sane value to cut only high freqs that would interfere with reproducing the sound, & common to digital synths & analogue. Again, anything w/ a DAC will have a final lowpass/reconstruction filter.

@acemonvw: You're right that the synthesis isn't accomplished with filters, but I've heard this trivia-bit about the TX7 from a number of sources. I recall that various Yamaha FM synths do have filters to remove unpleasant high-frequency components/aliasing from the finished sound, but I'm not sure to what extent that would really make the overall sound "warmer..." I'm curious as to whether this has any basis in fact...
