I'm still in the midst of reworking the SEQ-16 circuit. Everything is functional but not very practical in this state. I have lost track of how many jumper wires there are in this big mess. As a friend put it, "rainbow spaghetti." The process of recreating the circuit, laying it out, and testing everything has allowed me to make a couple of improvements, as well as take out some unneeded components (while adding some in other places).
I did not get a chance to record any music yet with this hooked up to the rack, but I will try and grab a sample to demonstrate the functionality.
More to come.
