Hello,

After reading many reviews of OXI1 and polyendplay I concluded that the Hapax was probably the best for me. However I wanted to test it without buying it. So, I made a simulator in js with Codex, it is able to control successfully my Nina from my iPad (however you must open the link in WebMidi instead of Safari to use midi). It’s far from perfect and I only spent a few hours, but I would be happy to share it for fun.

Here is at least the gui:
