What people said
“I'm asking people to test some Window and Linux previews that I have here: I'd be interested to see how it does on instruments. I've not had the bandwidth to try myself.”
“Will do, check out to register your interest in other platforms. Need to test feasibility.”
“Show HN: OnKey – I'm a bad singer, so I built an app to show where I'm off-key (237 points)”
