Eventide - Company Biog

Eventide have spent the past 50 years creating technical solutions for various industries. Richard Factor initially founded the business in 1971 to create custom-made solutions for studio engineers. The first product was a tape search unit for the Ampex MM1000, built for New York producer Steve Katz to assist his workflow in the studio. This led to Ampex themselves requesting units and a range of small electronic projects followed. One of those projects became the 1745 Digital Delay Line with the introduction of RAM and, later, pitch change.

In 1972 Tony Agnello joined the company and developed the H910 Harmonizer® which became a huge success and was followed by the H949 with ‘deglitch’ feature, allowing for cleaner pitch control. At this time they started to develop products for the broadcast market, including the Monstermat and the Mono Stereo Matrix unit. This led to them developing HP compatible RAM boards, and HPIB buffers and ethernet cards. In the '80s they returned to their original idea of developing a general purpose digital audio processor utilising DSP, and the Eventide SP2016 was created.

Following a move to larger premises, Eventide became involved in developing moving maps for aviation use. They also solved another problem for the broadcast and customer service industry by creating the Logging Recorder, using DVD-RAM storage media. Today their tech is used extensively within the broadcast, music, aviation and customer service industries.
