STOCHASTIC INSPIRATION GENERATOR & OMSONIC //
I thought omsonic made the Stochastic Inspiration Generator?
Stochastic and its Expander are no longer being manufactured or sold by omsonic. While omsonic were the original manufacturing partner for the Stochastic Inspiration Generator they were unable to meet the demand for the module.
In mid-October 2020, some concerns with omsonic's outgoing communications necessitated my personal involvement in the 'shop front' on
this MufWiggler thread. Up to mid-November 2020 we were assured by omsonic that production would quickly increase, so we persevered on that basis. However, at the end of November 2020 we received an email from omsonic stating that production was on indefinite hold. At that point we made the decision to part company and take over production ourselves.
It took December 2020 to accommodate the manufacturing changes, arrange the legal requirements of forming the new Stochastic Instruments company and negotiate the exit agreement with omsonic. Our complete redesign of the hardware is optimised for outsourced SMD fabrication and vastly expedites in-house completion.
We are pleased the situation is now resolved amicably and are now free to manufacture and sell Stochastics exclusively under the SI name.
Stochastic Instruments will never experience the issues that beset omsonic's handling of the project in 2020.
In recognition of their role in SIG's early stages we offer a panel option that retains with updates some of his panel artwork on our SI SIGs, under licence.
Do SI & omsonic Stochastic Inspiration Generators differ?
SI boards are expertly designed for reliability and performance. If you are one of the very few with an old omsonic unit we have already contacted you with our Replace-And-Upgrade offer (if you have one of these and we havn't contacted you, please get hold of us on the Contact Page).
SI Stochastics are largely functionally identical in performance operation to the omsonic-made ones, but our SI hardware redesign (primarily intended to optimise scalable manufacture) brings several important upgrades:
Only SI SIG/Expander units…
SI units ('Rev-E's) are easily differentiated from the omsonic Rev A-Ds: their finish is in shinier 'white gold', they show the Stochastic Instruments name and logo, have a dotted line connecting the Tempo and 1/16 controls (to indicate their special Control functions), and the PCBs have single rather than double expander headers on the back (see below).
Flash Storage Memory to retain their settings after power-off
use a faster MCU chip for optimised performance
have a TRS ClkIn jack to set an
Arbitrary Barline on an external trigger
32mm Skiff Friendly
have CV calibration trim pots
use keyed and shrouded headers to avoid reverse power issues
Analogue Noise Source rather than a PRNG
where available have
Centre-Dented Sliders to better identify
50% probability point
‘home’ Individual Note Octave
16bit TrEG Outputs
Are SI & omsonic Stochastic Expanders compatable?
No. But don't worry, we have everyone covered.
The Expander brings Stochastic's track count from 1 to 4 probabilistically independent tracks, increasing the capability of the system dramatically into a completely self-sufficient multitrack sequencing ecosystem for only 4hp of extra footprint. With a careful selection of sound modules this can make a fully performably probabilistic track (e.g. stochastically performable melody, chords, bass and drums).
Rev E and pre-Rev E main units must match their Expander versions:
Rev E SI Stochastics can only be used with Rev E SI Expanders (also clearly identifiable from their panels) and Pre-Rev E (omsonic-made) Stochastics can only be used with pre-Rev E (omsonic-made) Expanders. Omsonic boards employed two small ribbon connections and SI ones use one large one: there is no mechanical way to cross-connect thus no risk of accidental damage.
If you have an omsonic board and want an Expander, don't worry: SI will Replace-And-Upgrade your omsonic unit for a superior SI unit at a very considerable discount and offer the compatible SI Expander at no additional cost to the standard price. We will handle this directly by email to avoid confusion (i.e. there is no product page listing for a pre-Rev-E Expander). We have the list of everyone (we believe) sold an omsonic model and have mailed them already. If this applies to you but have NOT heard from us, please
contact us we'll sort you out.
If you don't yet have a Stochastic you'll be getting a Rev E from us so just request an Expander when we email (see below) or add one to your basket when they become available on the products page of the site: because we ship them together, you’ll save £10 on P&P if you buy them together!
Where am I on the Stochastic Inspiration Generator Waiting List?
Due to the serious issues with manufacturing and communications with omsonic there was a waiting list for the Stochastic Inspiration Generator. Happilly, once Stochastic Instruments Ltd. was formed to take over the operation things started to move, and we have now cleared this initial list. :-)
While we did this over 2021, thanks to the incredible positivity the Eurorack community is showing us, requests and demand directly to SI for SIG grew significantly. We feel the fairest way to handle this is to honour these enquiries in the (ongoing) order we receive/d them, so please visit our
Contact Form to reserve your place in the list and guarantee you get your SIG as soon as we possibly can!
SI is therefore contacting everyone on our ongoing list in the order we received your first approach. As long as you asked to be added and recieved our reply then we will be getting to you as soon as we possibly can. When we do, we will contact you again and arrange shipping to your destination. I'm afraid I cannot give an exact date for when this would be—however, progress through the list is going very well (thanks largely to our new UK manufacturing system) so it will be absolutely as soon as possible. Most important, rest assured your SIG is safe!
All this means you are in one of three groups of people...
1) People who got an omsonic-made Stochastic from omsonic
If you're in this group: thank you for being early adopters! You should already have received our special
SI Return-And-Upgrade offer and had your units sent by us! Omsonic is not making omsonic-compatible expanders, so if you have an omsonic and for whatever reason were not offered this, the only way to get a full 4 channel system is to
contact us and we'll sort you out.
2) People on omsonic's waiting list who never got one from them
If you're in this group: the list is now cleared! You waited so long––thank you, genuinely, for your support and interest. We are very sorry things took so long with omsonic but creating SI solved the problems and you should all have your SI units now!
If you have NOT yet heard from us then it means either we never got your email from omsonic or our email to you might be lost in your spam folder. Please
contact us with proof of the first date you contacted omsonic and we'll sort you out with your SIG+EXP immediatelly!
3) People who have contacted us at SI for a unit since we took over
If you're in this group: you may well already have your SIG and are raving about it on our Feedback Page! If you don't already have your SIG+EXP as long as you have asked to be added to the SI list, we are fast getting to you.
As I say, the incredible support we continue to receive from the Eurorack community for SI and SIG means SIG is now much in demand. To manage this demand fairly we are emailing people in batches by the date of when they first emailed us. We are manufacturing in parallel so can send out units in the order we receive the replies, pending payment arranged and confirmed by email. However, the only way to guarentee your SIG is to be on the list via the
Please bear with us: we are fulfilling the backlog as fast as we can and we will get to you.
The more time we have to get our heads down and honour the list, the quicker everyone will have their module so please only contact us with really critical questions.
We also completely appreciate you will be anxious to know where are on the list, and how fast we are progressing but again, please could we just ask that you let us work through and get to you as soon as we possibly can?
We promise you will hear from us more quickly if you just let us get to you.
When will the Stochastic Inspiration Generator go on public sale?
We had initially anticipated that public sales of Stochastics / Expanders would start as soon as the omsonic waiting list was cleared. While we have indeed now cleared the omsonic list, we had not realised the demand for SIG direct from us would be so high.
This is a wonderful problem for us to have(!) and we are eternally greatful to you all in the Eurorack community for the incredible support you have shown, and continue to show us. We want fairness to lie at the heart of our customer policy and so we think the best solution for everyone is to serve everyone in the (ongoing) order they came to us.
Please be assured that this actually means we will be getting to you just as quickly: it just means we can also guarentee the people how have waited the longest don't have to wait any longer than absolutely necessary for us to actually manufacture their SIG. We really hope you understand and ask you to be patient just while longer while we get to you.
If you don't yet have one, the only way to guarentee one is to reserve your place in the list via the
Contact Form. As soon as we get to you we will contact you and arrange shipping to your destination. I'm afraid I cannot give an exact date for when this would be—however, progress is going very well thanks largely to our new UK manufacturing system so it will be absolutely as soon as possible.
Thanks for understanding.
Who is supporting omsonic (not SI) Stochastic Inspiration Generators?
omsonic should continue to provide support to all the Stochastics they sold. However, we have Replaced-And-Upgraded the vast majority of these, and so of course at that point we will take over responsibility.
Obviously all SI Stochastics fall under SI's ongoing support. Please see our
Policy page for more details.
Will the price increase with SI SIGs?
Prices remain frozen: we are honouring the original ‘omsonic’ rates for the Main unit and Expander.
While Brexit and CoViD bring their own uncertainties, at the time of writing it does not appear that our production/parts costs will rise dramatically, and we are absorbing the small increases at our cost for you.
We will only ever increase this if external factors further raise costs significantly in the future and will always be transparent about this.
However, Brexit has created import issues for the EU. Like omsonic, SI is too small to be VAT registered so for both omsonic and SI, the sale price was/is the actual price: there is no VAT to remove at the point of sale. In turn, as with every other UK export following Brexit, EU customers are now charged VAT, Duty and processing fees in the same way as US customers (for example) would be. There is nothing we can do about this. It's not the way we wanted it.
Please see our
T&Cs for more information. It is important EU customers are aware of this.
Why doesn't the SIG have any CV ins?
First and foremost, our design ethos comes from a playing tradition, alloyed to a love of process within the modular ecosystem. Setting a process into motion and letting it run only holds so much interest so the SIG is about making something that exists in the hinterland between instrument, sequencer and dueting partner. It should respond to you, rather than either doing exactly what you trigger or entirely its own thing.
Obviously there's a practical aspect to adding CVs: it would increase price, footprint and decrease ease of use (there are something like 73 separate parameters the SIG can control, and clearly 73 CV ins is not feasible). But much more important is the underlying concept: we want you to be able to
play (or rather influence) these, in real time
with your fingers. We aim to encourage muscular interaction with SIG rather than 'outsource' control to an LFO or secondary sequencer so all its controls and design is geared towards that: even its playable Loop manipulation where you can beat-repeat, reverse, and otherwise mangle it.
Do I have to menu-dive to play SIG?
No! Even without reading the manual SIG's controls are completely intuative to both brain and fingers: everything is where it feels like it should be.
But SIG is also
deep. With 73 controllable parameters, a 1 knob 1 function approach would be counterproductive: the footprint would be huge and interface less (not more) intelligible. We follow a design philosophy of "intuitive intelligibility": everything you need, pitch, duration, octave, Loop, is under immediate primary control, and everything else is only a button hold away. You're neither compelled to use 2ry/3ry functions nor hunt for them with a screen, and SIG's note-specific functions are bound to each note so in performance the connection between finger and function remains absolutely obvious.
Who are dBs Music?
You will see the dBs Music logo on our modules. dBs is an highly innovative and long established teaching and research institute in music, audio and sound engineering based in Plymouth UK and with sites in Bristol and an afiliate institution in Berlin.
SI company director Phin Head has been a staff member there for nearly 20 years and, lectures there in Electronic Music Composition and Performance and also heads up their ground-breaking Modular Research Group.
The MRG is an open research forum open to any staff or student member with a good idea related to Eurorack and/or music software that they want to develop into a product. It aims to help integrate accademia with industry (a key dBs ethos!) both through the generation of new ideas and through connections with our friends in the Eurorack community (see below) where we collaborate on beta-testing.
The Stochastic Inspiration Generator grew out of support from dBs, and both Phin and Stuart see their industry work as a fully integrated aspect of their academic teaching, allowing their respective students in music and electronic to see innovation in the flesh and the marketplace, not just the classroom.
SI maintains extremely close ties with dBs Music (as the teaching institution) and also its sister companies
dbs-i (where Phin is a research collaborator) and dBs' commercial wing
To recognise this, and the essential link between innovation and education, we proudly put dBs' logo on our modules to thank them, our colleagues, and our wonderful students for their continued support.
Our freinds in Eurorack
The Eurorack community is mostly small (often single operator) companies doing amazing things. Along the way, we've met many extraordinarily talented people making incredible modules. Best of all, because it's people making things that interest them as individuals, there is much less sense of direct competition between makers than with the big music tech giants.
In no particular order, we'd like to shout out to our modular manufacturer friends, from whom you will find many wonderful things.
Tubbutec - Tobi makes the best multifunction MIDI & tuning system in Eurorack, period (and much else besides). Phin was lucky enough to get to beta-test it and deliver a
microtonality lecture/gig on the µTune at Superbooth '18.
ThisIsNotRocketScience - Stijn & Pricilla, working out of Amsterdam have somehow found a way to reinvent the building blocks of modular with incredible combinations of familiar concepts with innovative twists. And, the new Fenix will be a history book classic.
WMD - from Denver Colorado, Will, Alex and friends build modules that combine the grit of urban techno with the intellectual refinement of process-driven composition: truly modules for players, by players. The Performance Mixer, MSCL and Overseer redefined output staging in Eurorack, and Metron is simply untouchable for trigger sequenceing. We would also like to personally thank Will for his kind technical advice during the manufacture of SIG!
Kinesotronic - Our great friends, colleagues and collaborators Matt Ward & Chris Pratt created the incredible
Refractor multidimensional gestural morphing application initially for use in Ableton (bridged to Eurorack via a DC-coupled soundcard) but are already planning to take this much further.
Winter Modular - Eloi's 8 track powerhouse has fast become the centre of many people's racks and with good reason. There's little to touch it in terms of compact immediacy and functional depth and it's saved Phin's life a few times an hour into an improv set! We would also like to personally thank Eloi for his kind technical advice during the manufacture of SIG!
Superbooth - Where else combines an international academic conference, a music festival, a trade show, the best
vegan food in the vegan capital of Europe, and
Jean Michel Jarre on a shopping trip?
Herr Schneider's carnival of wonders is our annual pilgrimage.
What the hell is a milliWard?
The bigger the rack, and the more experience you have, the more you can do, for longer: but how do you measure that?
SI's Phin Head and his great friend and colleague, modular DJ, composer and lecturer Matt Ward derived a unit of "Eurorack skill". The 'Ward' is defined in min/hp where 1Wd = 1 minute of decent music per 1hp of rack space. That is, the more skilled the player, the longer the set they can get out of a given rig size.
1 Ward is a big value (like a Farad!). WMD's Will and Alex (drinking with us at the time...) reckoned a maximum set length of about 40mins was possible with two rows of 104hp, so thats 40/208 = 192 milliWards of 'skill' –– and those guys are world experts, playing live several times a week, week in week out.
Matt and Phin managed a 2 hour set with two 65% full 4 row 126hp rigs = 120 / (65%*(2x4x126)) = 183mWd which they were actually pretty pleased with.
So there it is, the milliWard––get practicing people! :-)

I've heard going vegan can save the world?
Well, funny you should ask, but, yes, that's right!
Animal Agriculture––meat, fish, dairy & eggs––kills 3 trillion animals every year, 95,000 every second of every day. The multidisciplinary
science is clear: the
animals feel and suffer, the
environmental effects are devastating (it's the leading driver of the 4 main non-warfare existential threats to organised human survival,
Antibiotic Resistance (AMR),
Pandemic Zoonoses (like
Pandemic Obesity), and its direct effects on
human health are serious too.
But the really great news is that the
dietary science is also really clear and really positive:
vegans thrive and enjoy
significant health gains from birth, reduced heart disease, cancer, diabetes, infections and obesity...and the growth in delicious, cheap and healthy vegan options is
So, here are a bunch of
really amazing recipes for you!
Save the world, be kind, love food and play modular. :-)
How do you Calculate Shipping Charges?
We have worked hard to secure the best balance between cost and security for your valuable package––particularly in the current climate of uncertainty with Brexit and CoViD. We also never profit from our P&P: everything is done at cost. Please see the Shipping section of our Policy page.
What are your Company Ethics?
Stochastic Instruments believes companies should be inclusive of everyone, transparent, pay taxes, ecologically responsible, supportive of education and above all, ethically brave. Every big ethical step forward a society takes was once unpopular, born from the fortitude of individuals striving for a better future and a better world. We believe this applies to all its sentient inhabitants, irrespective of race, colour, creed, belief system, gender, sexuality or species.
We bank ethically, use biodegradable materials wherever possible, try to minimise energy use, and ensure that we and, whenever it's possible to control, the services we use, do not invest in military, tobacco, gambling, tax-avoidance or animal agriculture products/services.
What about custom panel colours?
Company panel colour is black but we recognise that Eurorack is also all about individuality. If you really wanted a particular alternative colour it is something we can explore, but is limmited by the options available with the PCB fabricators we use and will cost more as it will be a special order. If you still want to pursue this, please contact us.
Finally, please see our
Support page for details of how to make your own panels if you really want to show off!
What about Brexit?
Music transcends all barriers: including those artificially forced upon us by politicians. SI hopes this is au revoir e auf wiedersehen––it's
EuroRack, not BorisRack––but until then, our EU friends should expect a similar situation to ordering from a US company.
We are too small to be VAT registered so our sale price is the actual price: there is no VAT to remove at the point of sale. As with every other UK export to the EU, EU customers are now charged their local sales tax, Duty (typically 0-3% on electronic goods) and processing fees. There is simply nothing we can do about this.
We can only provide the cheapest reliable shipping options available (and a range of pricing/insurance options within that), as well as the appropriate customs paperwork stating the full value of the items.
As a brand new start up already facing potentially increased production costs through Brexit, sadly we cannot absorb the additional costs for EU customers that these politicians have created. Thank you for understanding.
Please see our
Policy Page for more information. It is important EU customers are aware of these details.
I'm a fashionista and would like both panel colours. Can do?
Company panel colour is black, but in honour of the original omsonic SIG, we also offer blue. If you wanted the option to buy both to swap between them, no problem! We charge an extra £5 for the SIG Main Unit and £2.50 for the Expander panels so please contact us before placing your order and we can ship with both colour panels included (one fitted, one loose).
In addition, due to customer demand we now also offer Stealth Edition panels which retain omsonic's graphics but in a more muted profile which can also be added to your order.
