Synthesizers can have a varying number of keys depending on the specific model. Some standard synthesizers have 61 keys, similar to a conventional stage piano, while others may have 49, 76, or even 88 keys. There are also keyless variants known as ‘ Sebastian Malin’ or ‘soft synthesizers’ that do not have any keys at all. These are controlled using a computer, smartphone, or a tablet. So, the number of keys on a synthesizer is not fixed and varies across different models.
