Synths ⇝ Yamaha ⇝ Yamaha TG77
The TG77 is a hybrid synthesizer that combines 6-operator FM and AWM2 synthesis for some very expansive sound creation capabilities. Yamaha refers to the FM synthesis as AFM, meaning Advanced Frequency Modulation. The "advanced" part comes from the availability of extra oscillator waveforms - 16 in all, with 45 different algorithms available. Each of the two engines is 16-note polyphonic, allowing for up to 32 notes of polyphony depending on how sounds are structured.
The TG77 is a rackmount version of the Yamaha SY77. It lacks a sequencer, but is otherwise nearly identical. The Yamaha TG55 is an AFM-only rackmount tone generator from around the same time and uses the same button style.
It has PCM waveform and data card slots, and expansion cards typically come in pairs. View the available expansion cards.
The display back light commonly burns out on these units. It can be replaced, and the screen is usable without it, but it is harder to read without a working backlight.
