The SY35 is a hybrid FM/PCM synthesizer released by Yamaha in the early 1990's. It has a 2-operator FM engine, 2MB of waveform sample ROM, 16 performance memories, and can also use expansion cards to increase its sound palette.
The key feature of the SY35 is a joystick that allows morphing from one sound to another. It can be set up to morph between two or four different sounds depending on the patch settings.
It is very similar to the Yamaha SY22, but contains higher-quality waveform data. The sound sets have a lot of overlap, but are not the same. The TG33 is a tabletop module in the same series.
The SY35 uses a PA-3 external power adapter and uses a standard CR2032 lithium battery to maintain its patch memories.
