The EVI (Electronic Valve Instrument), a trumpet-style electronic musical instrument in the Wind controller family, was developed in the early 1970s by inventor and musician Nyle Steiner. The EVI is an endangered instrument and the EVI player is an endangered musician. Why? Because no one is creating new EVIs anymore. Nyle Steiner was making MIDI EVIs for a period of time, but no longer makes them.
IMO, the EVI is one of the finest windcontroller designs in existence. The octave mechanism is sheer brilliance, and the vibrato mechanism is the best thing out there (IMO). The fingering system is efficient and fluid. It's a great instrument. But it's an abandoned instrument. A relic. My EVIs are older than my children and they are about to go to college. An old trumpet can live forever, but a technological instrument ages in iPhone years. Our EVIs, even the Midi EVIs, ARE ANCIENT!
Our choices these days are trying to find a used EVI (which is rarer than hen's teeth - you essentially have to wait for an EVI player to die), or use an EWI or Aerophone in EVI fingering mode. Those are grim options for those of us who really like the EVI design. The EWI in EVI mode is OK, but it doesn't come close to a real EVI, IMO. It's only an option if my EVIs get stolen. The only option is for EVI players to make their own EVIs in the future.
I have decided to explore creating my own EVI with micro-board technology such as Raspberry Pi and Arduino. I would still GLADLY pay top dollar for a new EVI but there is currently no options on the market other than used MIDI EVIs which are virtually never available. And they are old technology now.
In short, the EVI as a musical instrument, is at risk of being left behind. EVI players (and I am one of them) are in serious trouble down the road unless we step-up and take measures to preserve this well designed and long used instrument. It may fall on the individual at this point. The EVI is a superb musical instrument. It deserves to be preserved and improved (like the Bach Strad trumpet). This project will attempt to create a reliable and gig-worthy DIY EVI using commonly available materials that can be used professionally.
I invite all interested electronic musical instrument enthusiasts to join me and help SAVE THE EVI.
