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.
The SY35 uses a PA-3 external power adapter and uses a standard CR2032 lithium battery to maintain its patch memories.
