This adapter met my expectations completely. I connected him to both an electronic drumset as well as on a very old (20 years +) Keyboard and had no distracting latency / delay in any case. Very good!
Tip, if the detection of the actual notes played incorrectly works: try around with the MIDI connectors! For example, do the IN connector to the OUT jack, sometimes pull out one of them, etc.
Tested Hardware:
