While researching these lego builds, for the classic Tony Banks keyboard setup, I came across some very interesting youtube videos. The videos feature Dave Kerzner, Tom Lord-Alge, LileighWhiteLilith and the amazing Musical Box.
The Classic mid-70’s Keyboard Instruments
The first synthesizer used by Banks was the monophonic ARP Pro Soloist, which he first acquired in 1973 along with a Hammond T-102 and a Mellotron M400 for the Selling England by the Pound album. In 1974 he also started to use the RMI 368x Electra Piano and Harpsichord.
This is a very interesting series of videos delving into the wonderful vintage setup used by Tony Banks.
