Its funny....what goes around comes around. Ketron (distributed through Solton) pioneered the arranger...and guess what the format was? Modules.
They were originally designed for Accordionists. Google Disco 64 or Solton Polyvox.
According to the details I can find they came out in the early 80s, however some organ manufactures made similar in the 70s, so I wouldn’t say Solton pioneered them. (Primarily a European idea though)
