Yeah, that’s nasty - wasn’t noticeable on my hi-fi. Sounds a bit like the interference I get when I use my Blofeld’s usb midi connection, though not quite as bad. As I understand it there have been a bunch of hardware issues that delayed shipping, reports of units being swapped out more or less immediately too - say it’ll be well into the second half of the year before a clear picture emerges.
For all that, still a much better demo than the the previous ones - I like its character, if it works out it seems for me to be just the ticket for bread and butter vintagey chords and pads. And I definitely like the price tag. Still interested for sure, but I think it’s fair to say that it hasn’t been plain sailing in Parva land. Even leaving aside selfish considerations I’m rooting for the guy, the whole project is a brave move, hoping it works out for him.
