Hello all, Let me present myself. I am Paul age >70 living in Belgium. I own. A Roland digital piano since 1998 and used it in that time with a 80486 and Soundblaster 16 to reproduce midi files on Sibelius. I was studiing guitar at that time. Now so may years later i picked it up again but the world has changed.

I bought a usb to din 5 usb midi cable from NEEWER ref NC11 with the intention of coupling GUITAR PRO 8 on the macbook.

After puzzling with the settings i managed to have piano sounds represented on score and play midi files on the piano.
However this is not a stable connection. 

• Inititialy i have blue leds showing midi is on, laptop on, piano on. Then, there is not a way to say when exacly, the leds turn red and the piano shows error 41 meaning a MIDI communication problem.
• I know i have to change the internal battery of the piano but i think that is only for memory purposes. The piano's settings are standard to accept MIDI on channel 1.

The files i have are general midi files and some GS files.
I would very much like to use the GTP files from guitar pro to be reproduced on the piano in a stable way. As i said sometimes there are no issues but mostly it does not function.

What could be the issue here?
