Hello , how We can make a sound logic in new version , We have 2 ways
First is hard , but satisfaction . Make a special logic 8 bit for Pitch and 4 bit for Volume
This solution is very big and slow the simulation
But We can make a second way compact , and easy to copy
Use ROM first 8 bit for Pitch and second 8 bit split to 4 bit for Volume
Ok , but how make a logic for this , It`s simple
