Synthesizer - an electronic musical instrument that creates (synthesizes) sound using one or more generators of sound waves. The required sound is achieved by changing the properties of the electrical signal (in analog synthesizers) or by adjusting the parameters of the central processor (in digital synthesizers). A synthesizer made in the form of a body with a keyboard is called a keyboard synthesizer. A synthesizer in the form of a body without a keyboard is called a synthesizer module and is controlled from a MIDI keyboard or other device, such as a MIDI guitar. In case a keyboard synthesizer is equipped with a built-in sequencer, it is called a workstation. A synthesizer in the form of a computer program using a universal sound card for scoring and standard input-output means (computer keyboard, mouse, monitor) is called a software synthesizer.

1.We need a circuit for the device. (Every little thing, such as display backlight lamps, etc., does not work)
2. The key is faulty (works - does not work). The principle of the node is not clear. Perhaps there are some developments on the restoration.

1. Scheme.
2. Dirt or wear under the contact rubber bands on the keyboard. The principle of operation is the same as in the buttons on the remote control. Repair methods:
Cleaning the rubber bands, if only for dirt. If a lot of wear and tear does not help, then, normally, they need to be changed. If this is not possible, then use the old-fashioned methods, such as rubbing with graphite. But this is not good, because the dynamics of the keyboard is disrupted.

Thanks a lot for your answer! But the problem with the key is more mechanical (like the spring there is either worn out or broken - the key is lower than the others). how to disassemble and repair a node.

Yes, there are no springs there. This is due to the torn rubber band, so the key sags. Take off the back cover from the device, remove 2 narrow long boards on the keyboard (they are latched), get to the rubber bands and see everything for yourself. And for an elastic band you will have to bow to the ASC Yamaha.

Reads the flop poorly (you have to overload the floppy disk several times).
What kind of flop drives are suitable for this instrument - ordinary computer drives or some special one.

With flops, nothing can be said for sure. kaie kompovye can go, some can not. Sometimes you need to rearrange the jumpers. In general, replacing a flopak with a computer one resembles dancing with a tambourine. And the original one costs about 40 euros without taking into account the interests of the ASC.
