Demo of the YAMAHA DX7 digital synthesizer (frequency modulation synthesis) from 1983. I played it along with a Lexicon MPX 500 (reverb).

This DX7 has the JAHN SPX 1.6 installed. This is a great expansion from Germany, which was available in the eighties. It adds some very cool features, such as "double" mode (2 voices per key/8 voice polyphonic) and "quadro" mode (4 voices per key/4 voice polyphonic), which makes the sound really fat. These voices can be detuned like on analog synths, to make fat sounds possible. It also expands the RAM memory to 128 (4 internal banks). The MIDI OUT channel can be set from 1 to 16 (not only MIDI IN).

I bought the new backlit display from Ebay. A DX7 expanded this way sounds excellent! The DX7 MK1 is my favorite DX7 version, I prefer it over the newer DX7II, because it has the better basic sound, is simpler to use, it's better built, and has a better MIDI timing. And you have a real classic, which is heard on tons of eighties hits."
