Hi, i see this thread is very old, however it did not show any conclusion with respect to MisterCharlie's posts. I've encountered the same issue; as i use the gate off by writing the gate bit to 0 in the control registers, it does trigger the release of the vca, however it does not kill the sound thereafter. Is this expected behavior with the 8580? what s the proper way to program a note off? shoud i use the gate off, then use a timer to count to whatever milliseconds are required for the release and then write a 0b0000XXXX to the control registers? Thanks in advance for your replies. also, i'm not building a midibox, but a sid synth of my own (for my own pleasure and for my final exam for my bachelor's degree in electronics. See pictures attached :-) (the casing is under devellopment). Regards, David
