Jack Cookerly was an accordionist who was among the first to connect the instrument to the technology behind the electronic keyboard. He was chief engineer at Lowrey Organs and designed a number of unique and important advancements for the electronic organ. The resulting efforts can be found in the now historic Lowrey MX1. The MX1 organ had seven separate synthesizers that were all programmed to produce a given set of instrument sounds within the instrument. The MX1 was introduced at the 1979 NAMM show to a delighted industry. In more recent years, Jack has also been a noted composer and arranger.
