1. My order was delivered quickly ond tidy. 2. The USB to Midi Convertor cable has in me works the same way. Before, I could not establish a communication Keybord my Yamaha PSR-420 to the PC. Although I used the included MIDI cable (Serielen Port). 3. The control of the transmission direction by LEDs is very good. 4. In note entry with Keybord in program "MuseScore" I have great delay. But I suspect this is due to musical program (this feature is not yet mature). With z. B. Capella 1200 I do not have this delay.
