Here is the best online Synthesizer (the piano of all time! I decided to find and put some kind of “toy” on the site, but I couldn’t imagine that it would hook me like that! The sound can hardly be distinguished from the real one! As soon as I set it, I myself played 2 hours, since then I also play at work at times.
A free virtual synthesizer with nine different instruments: piano, organ, saxophone, flute, flute, strings, guitar, xylophone, double bass and six different drum tracks to boot.
The virtual synthesizer program does not pretend to be serious; the resulting music is not saved. But the entertainment as a whole is not bad. For the game, either the keyboard (the middle row of buttons) or the mouse is used.
