MIDI retrofit of 8x6 matrix keyboard

1 post in this topic

Hi,

 

I'm just checking how to go about this. The synthesizer I'm working on has an 8x7 active-high keyboard matrix. Actually, it's mostly a 8x6 matrix, however the top key (C) has its own data line. Lines KD1 to KD8 are select lines and lines B1 to B7 are data lines.

As you can see in the image below.

I have a Core V3 and a bunch of DOUTX4 and DINX4 modules (I expect to only need one of each). Is any other hardware needed to complete this? To be clear, I want to add MIDI input to the synth to control it from a DAW. Can the core run off 5V and output 5V to the data lines?

 

Thanks
