sequencer 4

so as i was learning about making the expander section for this.. (which is a little easier than the main unit...) slightly. i found a circut using a single chip that drives the leds in time with the clock from the main board.. this is what led (no pun intended) to think about a trigger sequencer unit as well for lfos. drums. envelopes.. whatever. so its actually pretty damn easy to do and i found what may be pretty interesting switches to use on it. thy're really small switches like those on the ARP 1601 for the gate bussing. so i though .. whaty not try them out rather than the big and more expensives spdts i used on the main unit. i also founf these flat top round leds as a close out for ridiculous prices as well.. so i rearranges the circut and used dpdt switches to utilise an led for trigger on status as the clock timing hits it along with the main blinking clock counter.. so we'lll see how that goes on a single row expander as a test of the idea.. i have an enclosure and faceplate from the trash to use up so.. it wont really cost much of anything to do (cept in time) so .. be goos to get it down and make some interesting and useful machines with it.
