Frequency divider with setable divisor

#1

trying to model the dopefer a 163 voltage controlled frequency divider
(http://www.doepfer.de/a163.htm), where the divisior can be set from 1 to 32.

i am aware of lokkis octaver, but chaining several of those would only give power of 2 divisions (i.e. octaves). the doepfer one produces "undertones", i.e. mirrors of the overtones (a bit of it is explained in the pdf linked on the doepfer site). these were used in trautoniums.

anybody got an idea, how to do this with existing objects or does it need to be coded?

thanks in advances

Following ! Im building a eurorack version of this dual clock div / octaver from AnalogLabSwiss

I found a very nice patch here from @valmir

Basically in some of them you can see the divider used and hopefully figure out how to use other divisions .

I didnt test yet the square patch yet, but I see some clock dividers used as variable dividers , so in theory looks like doable, but is tricky to read for me whats going on from audio-rate world to bool to message again ....

thanks!
i ended up with a design based on the screenshot you posted and hacking a control inlet to the clk_div object, following the "Hacking objects 101: adding modulation inlets" posted on this forum.
it does what i want satisfactorily, but has wetted my appetite for further explorations :grinning:

i attach the patch here, i hope my object hack (as embedded object) makes it thru.

(on the other hand, its a really trivial hack...i wish, i understood more about data types, to directly embed a blue float in).

Wow Cheers man ! Happy to see success :slight_smile:
Thanks for sharing the patch , I will be trying it out soon and potentially some others jump into the thread.
Its a really cool thing to have and they are basically the same thing { a clock divider and octaver down, clock mult octaver up } so there must be a super easy way we are not seeing .
Keep Axing !
