Hello all, thank you mother misty for starting the thread. I just came on here to do exactly that. I'll post all the information below, thanks for sharing the video. Lot of info here of course but people can skip it :hihi:


Hello hello, here's my second eurorack module øchd or ochd. It's pronounced "oct" as in octave or octuplet and as if by magic there's eight outputs on this module, an octuplet of analogue LFOs if you will. I often find I need more modulation, simple sources that will keep things moving and stop things getting repetitive. That’s why ochd was brought to life, to keep patches organically drifting and moving… and as it’s modular, we wanted an intuitive easy to use module with plenty of patchable tricks up it’s sleeves too!

ochd is a 4HP Eurorack module with eight analogue triangle LFOs. The outputs go from fast on the top output to slow on the bottom output. The default ranges are deliberate NOT synced. These are free running LFOs that were tuned by ear to be musical useful for a range of fast to slow modulations in a patch. Organic animation, drifting and musical phasing is the intention of the module. The rate control controls the rate of all LFOs globally and takes this into lower audio rates right down to 25 minute cycles on the lowest output. This can be extended even slower with CV, with the CV input and attenuverter on board and we can also track and hold the outputs with a negative CV, interrupting and holding modulation values with external gates of CVs. Another trick to take this from simple triangle shapes is to patch a spare output into the CV input and wave shape with feedback. Exponential curves, odd squares, stepped waveforms and more are available with some adjustment of the attenuverter and using different outputs to voltage control itself.

While patching a prototype at DivKid HQ Richard Devine said this was "the most organic little modulator ever" - lovely stuff!

This module is made in collaboration with Instruo and I'm very proud to be part of their amazing line up of modules. https://www.instruomodular.com

The full product description and specs can be found on the Modular Grid link or my website link below

DivKid website



Designed in collaboration with Ben “DivKid” Wilson, the Instruō øchd packs 8 all analogue LFO’s into a convenient 4HP package.

Each independent core is free running with rates con gured from fastest to slowest arranged from top to bottom. Each frequency range was tuned by ear during development to give the optimum spread of control frequencies running in parallel. Being 100% analogue, the LFO’s will phase organically with the ability to ebb and ow together with their global frequency control.

Modulation breathes life into otherwise static patches, but CV sources can often run out quickly. Even in larger systems. øchd adds a lot of movement without hogging a lot of space. Both small lunch box cases and larger set ups can be made to drift, move and organically change over time. With either subtle use of øchd to keep things alive or wider ranging use that drives a whole patch that drifts around itself.


• 8 independent, un-synced free running analogue triangle LFO’s

• Wide frequency range across the oscillators (160Hz to 25 minute cycle time, this goes much lower with CV)

• CV controllable global rate with attenuverter

• Track and Hold capabilities using negative CV to stall oscillator cores

• Bipolar LED display for each LFO

• Self patchable for complex wave shaping

80 mA +12V
80 mA -12V
0 mA 5V
32 mm deep

wicked little idea for a module - so simple, yet so useful and efficient in terms of HP-per-function without being really cramped :tu:

....and selling very fast!

Fantastic - congrats ben hex and Instruo! This looks perfect for the person who can never have enough LFOs (like me)!

Two questions (sorry if I missed this in the announcement video):

a) What voltage range is the input expecting?

b) What is the voltage range of the outputs?

Wow! All this time I was hoping someone will make a 4hp version of Batumi and here it is! Of course approach is different but it fits my needs. Gonna get one.

Thank you Ben Hex!

Batumi has four separate LFOs and four different waveforms for each LFO. It can’t be compared to Ochd, can it? :)

Ochd is a simple but clever module, though. And everything Jason does seems to be of great quality. So this is a winner, surely.
My second ever track using Mutable Instruments Rings. Here paired with Make Noise 0-coast and Arturia DrumBrute and Korg Minilogue. A rather bittersweet piece. ❤️

It says “bipolar LED display” but this doesn’t necessarily equal bipolar LFOs. Does anyone know the voltage range?

Well, my point of view is very subjective, I know. I mean I was going to get a Batumi, but in my case it would be an overkill. So Ochd is a better choice for me.

Instruo's design is top notch. I'm fairly certain anything they touch is going to be gold.

My synth is full at the moment, but I'm keeping on the radar should some room open up.

Congrats Ben! Super well executed!

Looks great. Want one! Was hoping this would be $150 usd not $180 though tbh.

I was kind of "meh" on Mutes because I already had that function covered, but an octo-LFO in only 4HP is insane. Quite often in planning out rack expansions, I've had a 4hp space possibly come up and I thought "nah, better just leave that open as future room to shuffle things for bigger modules" - here though is a module worthy of claiming a leftover pocket in a big system that gives a full-functioned-feeling result, or surely being a top-tier option in compact setups.

It's too bad their shapes can't be altered; it might have been nice to have jumpers on the back or something for that, even if it only changed the shape on all of them. I also wonder if a button toggle to select the individual LFOs to adjust rates individually could have been done over a CV/attenuator, but the idea of simultaneously tweaking 8 LFO rates at once via CV is also really cool and will encourage unconventional exploration.

$185 at Control, and they are not even taking anymore preorders till they get the second batch. :cry: I should have jumped on it when I first heard about it this AM :doh:

What would be the benefit of that, considering the 8 LFOs all run at different, non-sync'd tempi?

It seems like it will be a great companion for an Individual Wavebank Batumi to keep a patch animated. Also... Black!

I was just shown the North Coast Synths Fixed Sine Bank a few days ago by a dude I bought an Instruo oscillator from, and he mentioned how much a gamechanger it was to have a box that was just organically ratio'd lfos out with no settings. I'd been thinking about it ever since and even got a kit in my cart – thankfully I didn't buy it because Instruo's new drop is cuter, smaller, and has just enough parameters to keep it extra functional but not too much.

I can't wait to get one when I upgrade cases.
