Yamaha TX816 For Sale. You all know the classic Yamaha DX7, the best known digital synth ever. World famous for the beautiful synthetic sounds generated by its FM synth engine. There's hardly an 80's synthpop band that didn't use one (or many)! This TX-816 is essentially EIGHT DX-7 modules in a single rack - the ultimate multi-timbral FM synthesizer, featuring a whopping 128 note polyphony! I believe it originally sold for several thousand dollars when it came out in the mid 80's. This was THE synth to have at the time and, to this day, is still quite widely used.
Basically, the TX-816 is a modular synth containing 8 DX-7 cards. Each card, also known as a TF-1, is 16 note polyphonic, can hold 32 of its own sounds, and can respond to its own MIDI channel. It can receive patches from the original DX7 or other TX816s.
