L'article présente un défaut de conception. Il transforme le jeu des pédales en note. exemple pédale forte devient E3.
Plusieurs utilisateurs équipés de Yamaha, comme moi, ont rencontré le problème.
Une analyse trouvée sur le net :
it seems, that you are getting Note On 64 instead of Control Change 64 Midi events.
A quick research in the internet showed, that several cheap MIDI to USB Cables hab Problems with some Keyboards.
The Amazon reviews for your Logilink cable (at least at the german amazon page) says, that there are some other people who have exactly the same problem as you.
Some other review says, that the user openend the electronics an it was not according to the MIDI specification. The opto-isolator and other parts are missing.
He than did the following changes:
resistor R11 -> 0 Ohm -> removed
resistor R3 -> 1 kOhm -> 680 Ohm
diode D1 -> BAS21 added
resistor R5 -> 220 Ohm -> added
opto-isolator U1 -> LTV817B -> added
After the changes everything worked fine.
If you are not into modding the USB cable by yourself, i would suggest, to test another cable.
I'm pretty sure everything will work ok with another MIDI to USB cable.
