Since the release date, all six production runs have sold out at the Japanese SONICWARE online shop (they are currently accepting reservations for the seventh production run, which will be shipped in October). It seems that a combination of factors, including a shortage of parts, makes mass production difficult. I think you can still make reservations, so be sure to check the English page of the SONICWARE online shop. *I've included a link to the SONICWARE online shop in the video description.
Thank you for watching the video. Ambient0 does not have a USB port, so you cannot record directly. I'm using an Android system, so I can't check on the iPad, but for this video, I input the signal from the Ambient0's Line out to SmplTrek, connected the SmplTrek's USB out to an Android (smartphone), and recorded and recorded using a camera app that supports USB recording.
