Yamaha SY77

Yamaha SY77 Image

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.

The SY77 was also marketed in a rack-mount module called the TG77. All the same features as the SY77, except the keyboard, sequencer and 3.5" disk drive are gone. Following the SY77 came the upgraded SY99. Its main features and guts were the same however it had increased memory, waveforms and a bigger keyboard. The SY77 (or TG77) is great for really controlling and creating sounds for use in various electronic forms of music and has been used by 808 State, Skinny Puppy, Brian Eno, Europe, Toto, Vangelis, Chick Corea, and Front 242.

I bought one for 240 euro and I still can't believe it. Amazing keyboard and amazing FM sounds.

Great FM, really bad filter. Very easy to make it (the filter) sound awful.

Professional Classic this is timeless, 16 tracks also with drum track and you will be immersed in the sounds, something for a synth player to keep forever.. If you see one snap it up, reliable, rare and an important synth to any set up.

I've had all three and the SY77 was my main synth for a long time, but now I only have the TG77.....I'll probably never sell it.....the DX7 inside it is miles ahead of the two real DX7's before it.....and it's wonderful to have a full range of effects for TG77 DX7 sounds (the first two series of DX7 keyboards didn't have built in effects).....also, the DX7 in the TG77 doesn't sound dated like the two series before it.....it sounds like samples without the annoying DX7 flavor of the two DX7's before it.....it is also more advanced than the two before it.
