Ok so in reason we all like to expand, tweak sounds and search for new refills right?
I'm a BIG BIG fan of instruments and synths from the70's and 80's when things were that good old analog.
A lot of these instruments are being recreate into vsti's...if you like the synths in reason than you are gonna love this synth from 1973 called "Yamaha CS-80.
This thing was a monster, it weighed about 200 pounds and cost approximatly $6,900 usd. You had to be rich to get one back in the day.
This Machine would get soo hot that musicians couldnt play it for long periods of time maybe about a hour im not sure. Musicians like Stevie wonder had a team that would go on tour with him just to carry it around.
The sounds from this thing is AMAZING i mean you got to see for yourself....
