INTRODUCTON I’d like to introduce this section focusing on the old glories, unique machines which are nowadays almost out of reach, in terms of price and / or availability. I wanted to share my studies and researches on the keyboards that made the history: Rhodes, Clavinet, Wurlitzer, Pianet, Mellotron, string machine, Hammond, Farfisa Compact, Vox Continental and the most famous synthesizers of the time. I will publish an article for each machine, trying to give a general and complete overview of all one should know about the subject which will be discussed.
