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 had one, and I really loved it. I had to sell it because it was too heavy. However, if I remember correctly, the 77 series (SY and TG) had 4MB of sampled ROM, while the SY99 had 8MB of ROM.

This keyboard looks great on first sight. The manual is a disgrace and the keyboard is not self explaining. So using all features like the sequencer is allmost impossible. There is not even an internal demo song. Some voices are ok but most are not worth being packed in such a spacious keyboard.

It is definitely a good synth! There are lots and lots of patches to be found and you can load up your own samples which makes this thing pretty awesome.
Distinct 80's sound and that typical vangelis atmosphere stuff going on.
Used it a lot !
I saw one in a small shop in my hometown for sale!

The description is incomplete. The SY99 is like the SY77 but with added user sample memory. So you can use your own samples.
