In the synth department you will find synthesiser keyboards and modules. Synthesisers were developed in the 1960's and the idea was that they would sound like other musical instruments as well as allowing the operator / player to create their own weird and wonderful sounds. Some early examples were the Moog synth or Dr Moog, the Art Odyssy and Roland and Korg models. The actual instrument sounds weren't anything like the real thing but the sounds created were very interesting and were liked by a lot of then famous keyboard players. The keyboard player was able to create his or her own unique sound using the many filters and oscillaters, effects etc.
As time went on in 1988 Yamaha came out with a digital synthesiser called a DX7. This synth was a major step forward as the instrument sounds were very realistic and they could be synthesised ( changed to suit the players requirements ). The DX7 was a milestone in synthesiser development and has become an iconic product that is still in demand today. The DX7 has probably been the most successful synthesiser of all time and even has other companies now emulating what is now called the DX7 electric piano sound.
One of our Directors Graham Blackledge still uses a Yamaha Dx7 today when he plays in the local entertainment venues. He said he can't get the same Dx7 sounds on any other instruments, particularly the DX7 string synth sounds and the modern electric piano sound
