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 owned the TG 77 and the SY 77 and together they provided everything I could possible need being a professional music producer. Some would sniggle and laugh when I brought them to the studio or a gig but after I performed, I ALWAYS got positive responses back. I sold them when times got tough Classic synths are synthes that stand the test of time being useful and 'musical' The Yamaha TG-77 can not be replaced, only upgraded and is much more than a classic. It ranks with Moog and Kurzweil and is even much better than the DX7 and some so called new synths!!!!

@ Peter, if you are OK with a soldering iron, try removing the back panel (lots of screws) and remove the power supply board, then resolder everything on it. Mine developed a number of weird and random faults and eventually started freezing up totally. Once I resoldered all the dry joints on that board, it worked like new again and is still working flawlessly today. I've had my SY77 since the early 90's and it is still my main workhorse synth.

lamster, the sy-55 and the sy/tg-77 cant even begin to be compared to each other. They are two totally different types of synths. The sy55 is a awm rompler only. The sy-77 while yes it does use awm at its heart its a monster 6op FM synth that will make the sy-55 seem like a cheap lil 8 preset battery operated Casio.
