Does anyone make a clock divider whose ratio is set by a switch or buttons? I'm thinking of something very simple : 1 input, 1 output, and the choice between clock ratios of 2, 4, 8, or 16 at the output.

I have had look through the MG database but I don't see anything like this. There are a few modules (2hp, SSSR) which are quite similar but use pots to change the ratio, and obviously lots of clock dividers with those ratios on different outputs. The effect I want could be achieved by combing such a classic clock divider with a 4-position switch but I was hoping to find it in a single module.


Maybe the Shakmat Time wizard is what you are looking for..


Hi The-Erc,

I can recommend the Time Wizard as well, very lovely tool and in every patch where I use a clock, I use it in combination with Time Wizard. I use it in combination with Tempo (from Make Noise) but you can use it with any other clock module as well, of course.

Kind regards, Garfield.

I've been adding Noise Engineering's Fractio Solum for this sort of thing in some of the recent builds I've done. Works as desired...but ALSO adds clock multiplication in addition to division so that you could just as easily use it for ratcheting.


Thanks for the suggestions guys. I don't think either of those modules does what I'm looking for.

The Time Wizard does look very cool and is clearly overkill fro what I want. Having peered through the manual I don't see a straight forward way to even get the binary divisions I want. The switchable ratios are 1:1, 1:3, and 1:4. If that 3 was a 2 it would basically work, although it seems ridiculous to use such a large and powerful module for such a small task.

The Fractio Solum looks good also, but I want to be able to instantly change the ratio, which I doubt I can do with an encoder.

I expect that this would be easy to DIY, but otherwise it looks like basic clock divider + switch is the way to go.


This DIY module from yusynth is pretty close to what I''m looking for.
(Found via this thread at Muff's which has a few schematics for making clock dividers.)


Hi The-Erc,

If you look for a cheaper and simpler clock divider, then why don't look into Doeper A-160-1 or A-160-2? The A-160-5 is a mulitpler by the way. Saves you the DIY part ;-)

Kind regards, Garfield.

Doeper A-160-1 or A-160-2?

They don't have switches.

Perhaps I should have explained what I want it for. I need a reset for looping material which will be either 1, 2, 4, or 8 bars long. I don't want to repatch to change the length of the loop. I want to do it accurately and quickly with one hand while my focus (and other hand) is elsewhere.

To achieve this with a plain old clock divider I'd need to combine it with a 4-way switch or something like the Malekko Mute 4


Hi The-Erc,

Ah, okay :-) Now got it, how about DivKids - Mutes?

Kind regards, Garfield.

Nah, Divkid mutes is four independent mutes, whereas the dirty secret of the Mute4 is that it is four mutes summed to a single output which is essential to my intended use here (and might screw you if you actually want 4 mutes!)


Ha, ha, okay fair enough, then the 4 Mutes it is ;-)
