Synths ⇝ Yamaha ⇝ Yamaha SY77

The SY77 is a hybrid synthesizer that combines AWM and FM synthesis for vast sound scupting capabilities. Yamaha refers to the 6-operator FM synthesis as AFM, meaning Advanced Frequency Modulation. The "advanced" part comes from the availability of 16 extra oscillator waveforms and 45 different algorithms. These FM and AWM sounds can combined into a single patch to build complex sounds and layers.

It has a 16-track, 1-song sequencer.

The screen's backlight will commonly burn out, making the screen harder to read in dim light (but still functional). It is fairly easy to find an aftermarket replacement.

The SY77 is available in rackmount form without a sequencer as the Yamaha TG77. The SY99 is an upgraded version with a 76-key keyboard.
