Show HN: Just intonation keyboard – play music without knowing music
I want to say first off that this is super cool, and I really applaud you for shipping it. The tones sound pretty great on my machine, and the button pressing is good. I don&#x27;t detect any jank or latency like I frequently do with web-audio.<p>That being said I have a few constructive critiques.<p>First is I wouldn&#x27;t say it&#x27;s intuitive. Having the harmonics ascending from right-to-left breaks my brain. Wait, on second look they are kind of scattered about in a somewhat random way? Why are 5 and 3 so far from each other? I might like it if this was laid out in a lattice or some kind of regular structure. I don&#x27;t doubt that with practice and reading I could learn it but, IMO, if I have to read an instruction manual I&#x27;m already checked out..<p>Second, there needs to be some kind of indication at where I&#x27;m at in terms of the internal state of the multiplied ratios. So if I&#x27;ve stacked on 3 consecutive 2&#x2F;3, the only feedback I get is when I hit a note.. and I might forget where I&#x27;m at in the &quot;pitch space&quot;. You could just have a simple &quot;stack&quot; at the top that shows the last applied ratio, and maybe the final product or quotient next to it.
