If you want to understand how a flip-flop works, read through Rob Hordijk's Logic Workshop and look for the chapter Logic and the outside world. Most of the ideas and concepts described here are from that workshop for the "old" Nord Modular and edited for the G2. Setting the flip-flop to "S" and using only the clock input will make it toggle between on and off (e.g. a keypress to start a sequence or a note or whatever). The output will be ON until the flip-flop receives another signal. If you want to turn something on with one signal (e.g. a key) and turn it off with another signal (e.g. another key), set the flip-flop to "D" and apply something >1 in the D-input. Pressing ON will then toggle the flip-flop and let the signal through. Pressing OFF re-sets the flip-flop and the output is nada again. The next example looks more difficult but is actually the same thing as above but with a similar additional circuit. Turn on one oscillator, turn on another one, and shut them BOTH down with ONE signal. Say you want to turn something on but only if something else is on, too. E.g. you want to start a sequence, but only in combination with a certain bass line. The D-type flip-flop does just that. In the below example the output you can trigger the clock as often as you want - if the D-input isn't above 0 the output will always be 0. When the D-input receives a positive signal, you can then turn the Q output on. The reset input is always the "strongest" party in a flip-flop, so pressing reset will turn the output to 0, no matter if there's a positive signal or not. You can use the flip-flop to run something (in this case a sequence) twice (or more) and let it stop automatically. |
