A musical instrument that generates sound using oscillators,
LFO's, filters, sequencers, and other things of that nature. Most true synthesizers are controlled with three things, a keyboard of various sizes, pitch bend and
modulation wheels, and a complex interface of knobs and switches. The
Minimoog is a great example of this. But the
main thing that makes synthesizers so unique and beautiful sounding is that they are not limited by the physical world to create sound. They are not a string instrument, wind instrument, or percussion instrument. Synthesizers are classified as quintephones. Which means they create sound informaticly. Synthesizers are very expensive but are a great thing to own and use!
