Yesterday it was possible to form the sent midi message in such a way that the software on the computer could recognize the midi as a hi-res midi. Thus potentially midi resolution can be 127*127(14bit). But so far, not everything is so smooth. With a keyboard polling time of 3.6-4 µs for my device, it turns out that midi hi-res capabilities are fully enabled at speeds up to ~11(velocity). Higher speed - resolution drops. Speed 60-61(midi-velocity) is divided into 6 steps. And at speeds of 125-126-127 - the resolution of the device is enough for the usual midi resolution.
The delay is also pleasing - the message flies to the usb channel 20-30 μs after the event.
