YMfos 10 step sequencer add clocks input |
|
|
Hi there, I want to add an external clock input to my 10 step sequencer. I think the input should go in where the step button is connected. Has anyone done this or have any thoughts on it? Thanks |

I'm planning on building the 10 step sequencer soon as well and was disappointed by the lack of external clock. Here are some of my thoughts: The step button probably just completes a circuit in order to tell the sequencer to move to the next step, whereas an external clock would be a 5V signal. I suppose you could measure what the voltage is running through the switch when pushed, then make sure that your external 5V source gets scaled down to that voltage??? I'm no electronics engineer so I am likely wrong, but It's what I had been considering trying. |

Simplest solution would be:
Input - diode - resistor to the junction R37/R38/C6
With taking something like 47k for the resistor and the diode "pointing" to the junction. |

It is one of Ray's earlier designs, so probably there was no need when designed. His newer sequencer proves a lat of progress in insight. |
