Need help adjusting keyboard.c

Hey,

 

I hope you are well.

I need help with my keyboard. I've got a Yamaha DX-11 keyboard here and also the schematic. I attached the necessary part (high resolution).

 

A few months ago I had another Yamaha keyboard here and TK really helped me and developed a variable in the keyboard.c to make it work. On this DX-11 I also need to set this variable to 1.

 

The problem:
 

I connected B3 to O6 on my DIO-Matrix, N11 to I3 of SR1 and N1 to I3 of SR2. Now I've got key F1 working fine. The next step would be, to connect another row to the DIO. So I connected B4 to O5 to hopefully get key B1 running... not working. But... and here I start to wonder ... if I connect B4 to O4, the key B1 itself works fine, but because I "skipped" a DOUT-Pin MIOS thinks, I press key F2 and not B1.

 

I know it seems complicated... to summarize:

I need to "deactivate" all DOUT-Pins with uneven numbers and to tell the software, to continue pin-counting on every second DOUT-Pin. 

 

Everything else is working fine... just this little issue ;)

 

I hope, you have any ideas...

 

Thank you very much,

Chris
