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.

Hey Tony
It is probably the battery. You get just rubbish in the ram, if the battery power is too low.
I am guessing ofcause, but it helped my beloved DX7s

Hi, i'd like to clear up the fact that the 3rd wheel can be assigned to a few different things, for example, filter cutoff (make sure the filter is set to LFO mode) panning, and a couple of other ldestinations. It's really nice to play a phat moogy lead and use the 3rd wheel to expressively filter it.

Does anyone know where I can get troubleshooting info for these. I have never had any trouble with mine but all of the sudden I can't get any voices to function. All i get is weird sounds, regardless of which setting I use.

@Laura - If the backlight is working nice and bright, then £250-£300. They are quite sought after on ebay.

Ok, so I have a Yamaha TG 77 in a rack mount case ,appears to be working and in really good shape. It was in my dads recording studio but we are selling his stuff now that he is gone. What is this thing worth with the case in really good (excellent even) condition?
