Up for sale, a Yamaha SY77 digital synthesizer workstation in excellent condition and in good working order. All features of this keyboard function as intended aside from the backlight on the display, and the keyboard shows only a few faint nicks on the edges of the enclosure.

The SY77 is like having a super-sized sample-memory workstation with the added synthesis and sounds of a DX7mkII. For its synthesizer section it employs a 6 operator AFM synth engine similar to, if not better than, the original DX's. The AFM section offers 45 algorithms, 3 feedback loops and 16 waveforms for creating some of those unique FM sounds. Sampled sounds (AWM2) which are in memory (or on external ROM cards) can then be mixed with the AFM sounds to create entirely wild new sounds! And these sounds are quite shapeable thanks to the resonant multi stage Time Variant Filters which offer the chance to recreate the warm analog sounds of classic synths, or create something entirely new.

There's an on-board sequencer section for creating your songs right on the SY77. It's got 16 tracks, channel 16 belongs to the SY77's built-in drum synthesizer which holds up to 61 sounds. The sequencer can hold up to 16,000 notes, 99 patterns and 1 song. And since the SY77 features 16 voices of polyphony for the AFM section, and another 16 voices for the sampled sounds, there are (32) plenty of voices to go around to build your song. Add the fact that there are 4 independent digital multi-effects which include reverb, delay, chorus, panning and more and you have yourself a classic music production workhorse.

Specifications: Polyphony: 32 (16 AFM layers, 16 AWM layers), shared between up to 16 voices Timbrality: 16 voices, each containing up to 2 AFM layers and 2 AWM layers Oscillator: sine wave and 15 harmonically enhanced variants thereof LFO: sine, sawtooths, triangle, sample-and-hold; can control pitch, amplitude, cutoff, etc. Synthesis type: Digital Frequency modulation, Digital Sample-based Filter: lowpass (12 dB or 24 dB), highpass, or multi-pole Storage Memory: 64 custom patches can be stored in battery-powered onboard RAM Effects: 2 reverb units (40 effect types) and 2 modulation units (4 effect types) Keyboard: 61 keys with velocity sensitivity and aftertouch Left-hand control: Pitch-bend, 2 modulation wheel External control: MIDI
