Muff's Modules & More

I don't know if this kind of thing exists in the euro world, but maybe there is or maybe there is a way to emulate such behavior.

I'm looking for a counter module.
An input is looking for events and puts out a gate/trigger after a certain number of events have passed.

something like "do X after 10 times (number should be adjustable) of event Y"

Does this make sense?

Wouldn't a clock divider work for this purpose? You can use a module like a slope detector or window comparator to detect particular events and send out a gate/trigger, then run that into a clock divider to send out a trigger for every X number of events. Or if you're setting the events with a trigger to begin with then just mult the trigger to a divider.

Endosine is working on a clock divider in this thread which would allow you to set custom divisions for your events. Beyond that there's the Doepfer and 4ms dividers as well.

Thanks for the input NV
A clock divider comes close.

Although it would just work with steady events.

For example if the event is not coming from a fixed LFO for example, but rather from something like a burst generator or a modulated LFO, it wold not be possible to output an event Y after a number of X events.

Plus, with a click divider i won't be able to select an adjustable threshold fo triggering event Y

The Snazzy FX Ardcore could probably be programmed to do this. If you can code, it is probably pretty simple. If not, you could ask some of the Arduino ninjas if they can get it running...

I think you can do this with several Doepfer A-151

a clock divider, like the 160, is just a counter. it doesn't care if the input is steady, intermittant or otherwise, just that it qualifies as what it sees as 1 & 0.

as long as the input signal qualifies as events it will count them & give you the tally as a binary number.

Edit; BananaPlug beat me to it.

[yghartsyrt]

Thanks for the input guys, but it seems i was not precise enough.
The module should trigger a gate (or something similar) after it received X events on its input no matter. A clock divider would give me the fraction / divisor of the input, but it won't output after it received a certain number of input events.

Or am i completely wrong here?

you just use X to restart the count, which is I assume the same way you'd do it in code, you may need some sort of delay - fire an envelope & get an "end of"

ignore the panel for a moment & turn the 160 on its side;



/2 = 1

/4 = 2

/8 = 4

/16 = 8

send it a reset, all the lights are off, a count of 10 will mean /4 & /16 will be on, AND those & you have X = 10.

hrm... i use the a-152 for that (it has a row of "digital outs" ~ gates), which has a clock in and then steps to the next step when high + reset input which you feed back from one of the outs for your desired "sequence" length; i guess you could use any step-sequencer (as long as you have to count to < number of steps).

[monstrinho]

It just occurred to me that you could patch all of the outputs of a clock divider (or the gate outputs of a step sequencer that has per step gates) into a Low-Gain Short Bus. Connect what you want to be triggered to the A and B outputs of the Short Bus, and just select whatever you want your "X" to be with the toggle switches. Probably easier and more accurate than using an EG as a gate/trigger delay.

Maybe you want the FSS decade counter? I don't know much about it but it seems to be what you are asking for.

[yghartsyrt]

it seems there was a bit of the clock divider concept that slipped my comprehension. Looks like that would do the trick.
Maybe the ardcore is something to investigate, too.

Thanks guys – you rock.

[earlykooka]

it depends if you want an event to occur every x clocks ( in which case the above answers are probably going to be useful, or if you are thinking in a sort of 'max/msp structure generation' way ... eg: seçtion one does something in a semi- random way until 117 events have occurred at a certain inlet that then triggers an event that changes many things into another state which is seçtion two etc etc

this is very common max/msp strategy, and very easy to do in max, seems to me that the best bet in euro for something like that would be the Ardkore ... it is certainly the sort of thing that would potentially interest me in that module.

however, i am a complete arduino ignoramus and still a relative eurorack noob so i might well be mistaken

You can probably get pretty close to what you want to do with a clock divider, intellijel flipflop and a plog. Although it would only work with even numbers.

Basically you hook the clock divider upto whatever trigger you are using to count events.

If you want something to trigger every 10 clock cycles (I think!).

Hook clock divider to cycle source.

Hook the first flipflop up to /2 on clock divider
Hook the second flipflop to /8 on clock divider
Hook both flipflops upto the plog and put it in boolean "AND" mode.
When both /8 and /2 are true output on plog will go high and trigger event.
Then use the normalized connection on the plog to reset both flipflops back to zero state.

I haven't had a chance to test it, but I'm sure that a clock divider coupled with a plog and flipflop will get you what you want even if this isn't these aren't the precisely the correct connection scheme.

Alternately if the event is time based and you're just using a counting device to track that timing you could use an LFO driving a square wave, and trigger when the wave goes high. You'll have to mess with the LFO timing to get things running cleanly but that *should* also work.

[andrewl0]

Actually I just looked at blacet hex zone, forget what I said and go with that if you have the cash.

[yghartsyrt]

@earlykooka yeah something along that way. But I think for starters the simple solution with a clock divider should work (although not perfectly)



@andrewl0 cheers – if I now find a solution for numbers that are not even I should be somehow set. I guess the RCD is something that would come close, since it also does odd numbers.

ah ok – thanks. Much appreciated.
