So that's one bit latch taken for that already. Then, your encoder project was probably going to use one or two latches. Adding a scanning latch to HAWK would not be too difficult so it would seem unnecessary to steal keyboard inputs.<


So can the code be altered to release that note hit latch?
I'm guessing the first three used up are required to pick between memories or something...

Am I following that it's possible to add in another 3 to 8 demux to create another scanning routine to a new set of matrix's?
