After trying to use my Instrument 1 (I1) for a dozen or so hours during several months, I gave up and sold it on eBay during November for $182. But unfortunately, the buyer was apparently also trying to use it as a guitar, also found it to be unuseable, and demanded a refund. Not wanting to pay for additional shipping to another buyer who might also demand a refund, I decided to cut my losses and told the buyer to scrap it.
I had watched all of the videos and tried all of the settings, but concluded that whatever hardware the I1 uses for sensors in the fretboard and the strumming buttons is simply not good enough music performance, regardless of how they are tweaked in software. There is little predictable correlation between how you push and the sound you get, or don’t get. The fact that like-new units are selling on eBay for less than half the original price suggests that many others have come to the same conclusion.
The I1 might be useful for musicians who want to lay it down flat and tap on the frets, as you see in almost all of the Artiphon videos. But, as a string instrument, the I1 is not.
I hope that other prospective I1 users find this post to be useful, and wish Artiphon well in designing better sensor hardware into their next product.
