peroja Posted April 24, 2010 Report Share Posted April 24, 2010 hello im working on a step secuencer with a 555 and a 4017 is it possible to bypass the input comming from the 555 into the 4017 with a clock signal? as example, right now the 555 gives the 4017 the clock signal for every step but i want to put a switch in between to switch to an external clock signal so the signal comming from extern gives the 4017 the pulse for the steps. i know what a midi clock is. either i want to build a midi clock that gives the signal to the 4017 processor and also gives the signal for another device OR to simply RECIEVE a signal from extern. any sugestions? thanks randy Quote Link to comment Share on other sites More sharing options...
TK. Posted April 24, 2010 Report Share Posted April 24, 2010 Hi, so long the MIDI interface only sends the clock signal (0xf8) and nothing else, it should be possible to create a discrete solution with a 1:6 divider (because 0xf8 is sent 6 times for each 16th step). Once other events are sent as well (such as 0xfa for MIDI start, 0xfb for continue, 0xfc for stop), it will get a bit more complex if you don't want to use a microcontroller. Best Regards, Thorsten.
