The first output is stage 6 (pin 2) so it'll take 6 transitions before the

Data on the serial input (pin 11) is shifted throughĮverytime the clock input (pin 10) changes from low to high. Ok, so when the par/ser control (pin 9) is low it works as a standard shiftregister. Yes, or at least you will only get 3 outputs at a time, but let me add that to the answer of the next question. Would love to hear any thoughts on this strange chip. But maybe a different shift register ic is more suited to what I want to do? One thing I like about the chip is that adding all the Q outputs together you get a kind of pulse phasing that sounds quite nice with certain percussion voices. When I pull P/S high it seems to just stop outputting anything at all.Īnd can anyone explain the last sentence of that quote about 'the clock input of the internal stage.asynchronous parallel entry.'Īnyone have an idea why it seems to stop spitting out pulses when the clock goes too slow or when the clock and serial are at certain settings? In the CD4021B, the CLOCK input of the internal stage is 'forced' when asynchronous parallel entry is made' Input is high, data is jammed into the 8-stage register via the parallel input lines and synchronous with the positive transition of the clock line. It also tends towards faster rhythms because it seems to stop outputting pulses when the clock frequency falls below a certain threshold, or if clock and serial oscillator are at certain settings in relation to each other.ĭoes anyone know if its possible to output p1-8 in plain vanilla fashion in the way that the Klee sequencer can play a programmed sequence back and then the user can affect or indicate how much randomness? So far what i've gotten out of it is interesting if not mostly arrhythmic, and very random and hard to control in any predictable way. I thought a shift register might be a way to expand this idea further.

Initially I'd been using several oscillators gating each other out of a 4093, and I was surprised at the variety of rhythms (and their musicality) that could be generated with just a few knobs. I'm interested in making a pulse generator/sequencer/pseudo-not-sequencer, that can go from standard user controlled input to controlled randomness. I'd be interested in hearing anything anyone wants to share regarding this chip, although I do have a few specific questions. Of course this is the chip used in the Rob Hordijk's Rungler circuit but what are some other ways it has been or could be used?
