Works well on Windows, not on Mac or iPad
For AZSMZ opto isolated USB MIDI Converter
This interface is nice and compact with competent build quality.
It functions perfectly on a PC running Windows 10 and apparently under Linux, according to another review.
Unfortunately, my intention was to use it with an iPad, which detected the device, but will not send multiple note at once / polyphonically. I also tested on two different generation (m1 and intel) mac laptops with the exact same issue, so if you are an apple user, it is unlikely to work currently, assuming my device is not defective somehow. Btw, the tests were all done using the same (confirmed working) usb and midi cables across all devices.
