Yamaha SY99

Yamaha SY99 Image

The SY99 is like having a super-sized sampling workstation with the synthesis and sounds of a DX-7mkII. Basically the same as the SY77 it features a larger 76 note keyboard with upgraded synthesis, sample memory, sequencer and more! For its synthesizer section it employs a 6 operator AFM synth engine similar to, if not better than, the original DX's. Sampled preset sounds (AWM2) can then be fused 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 ability to recreate the warm analog sounds of classic synths, or something entirely new.

There's an enhanced on-board sequencer section for creating your songs right on the SY99. It's got 16 tracks, from which channel 16 belongs to the built-in drum synthesizer. The sequencer can hold up to 27,000 notes, 99 patterns and 10 songs. And since the SY99 features 16 voices of polyphony for the AFM section, and another 16 voices for the sampled sounds, there are 32 voices to go around to build your song. Not to mention there are 2 digital multi-effects processors which include reverb, delay, chorus, panning and more! Professional features for those of you want to really control and shape your sounds using the unique sounds (and complex synthesis) of a Yamaha FM synth with some special features up its sleeve. It has been used by Vangelis and Chick Corea.

I just bought this synth and it is by far the most amazing thing I have ever laid my hands on. Even compared with modern high-end synthesizer workstations, this synth is very very impressive. The keyboard feels almost exactly like a real acoustic piano's keyboard, and the sound is nothing short of amazing. The amount of customization you can do to a voice is incredible; the UI hides nothing and everything is editable, so it's almost like having an analog modular synth. In spite of it's age, it has very impressive digital filters, and produces very warm and fat tones.

I bought one new, in 1992. Still have it.
A superb machine, I loved getting under the bonnet straight away to play with the RCM synthesis, mixing samples and FM. I have taken it apart a fe times , and recently serviced the floppy drive. I will never give it up.

I now have an SY99. Hooooooly brilliance. This thing is fantastic. (the usual dying battery and unresponsive floppy drive notwithstanding, which I'll have to operate on soon)

Also, gigantic! I previously thought my SY77 was pretty huge, but the SY99 makes it look like a little toy! Not sure how I'll ever move it around, but it'll be totally worth it. :D
