The Entropic Doom takes noise and tuned noise to a whole new level, it can almost be described as an oscillator for noise, or Noisillator as we like to call it. Traditionally in modular synthesis we use either white or pink noise and then treat it through envelopes and filters to give various effects, however the Entropic Doom takes modular noise creation to places its never been before!
We have a CMOS Logic Gate based Noise Generator with Coarse and Fine tuning control along with a two, three and four pole low pass filter and a passband resonator within the noise loop itself. We have both Audio and Sync inputs, which can be mixed into the noise loop to add even greater variety to the sounds generated. We have both Bright and Dark Noise outputs, which are pre and post filter respectively, however because the noise and filter are in a feedback loop the Bright output responds to filter type and settings too.
There are CV inputs to allow voltage control of both Frequency and Resonance, and also an all important 1V/Oct input so that we can "play" the noise in tune from a keyboard or sequencer.
In addition we have a separate XOR based Ring Modulator and a Cmos gate based VCA sub modules. These can be used independently from and simultaneously with the Noisillator circuitry.
What is the Entropic Doom?
The Entropic Doom is a very unique module, we like to think of it as an oscillator for noise - a noisillator! It has a unique and unusual topology, featuring a cmos logic gate that is biased for use in the analogue region between logic zero and one. We use this for controlled noise generation, and it is in a closed loop circuit along with a variable pole low pass filter and VCA. The output of the filter is fed back into the input of the cmos logic gate, which generates noise that can be tuned depending upon the resonant loop gain, filter frequency and filter pole selection. We can take the output from two different points in the noise loop, either pre-filter (Bright Out) or Post filter (Dark Out). We can also mix an external audio signal into the noise loop with the Audio In jack and level control, and also use an audio sync signal (Sync IN) to reset the cmos gate and / or mix in adio to a different part of the noise loop. We also have included an XOR Ring Modulator and XOR VCA too, each of which is rather different in function from its regular analogue counterpart.
Usually in analogue synthesis we use a reverse biased transistor or Zener diode in avalanche mode as a noise source, however the Entropic Doom takes a different approach and uses a CMOS logic gate in a biased, analogue configuration as a noise generator - this is useful as we can also apply as Sync signal to the other input of this gate so that the noise generation is reset, in a similar way that Oscillator Sync works on an analogue VCO.
The Noise core itself is contained within a loop that also includes a low pass filter, which can be switched between 2 pole, 3 pole and 4 pole configurations, and the feedback from this filter is fed back into the noise core itself to create a resonant feedback loop. We have two noise outputs, the Bright output is taken directly from the Noise source itself, and the Dark Output is taken from the output of the filter.
External audio can be mixed into the pre-filter section of the noise loop using the Audio In jack and its associated Audio In level control.
There is also a Sync Input, to allow a signal to be fed into the other channel of the Cmos logic gate that is used as a noise generator - if a square or pulse waveform is used at a suitable frequency then this gates the noise source to give a similar effect to Oscillator sync in a VCO - the effect is subtle, and most obvious when using the Bright output. The sync signal is also mixed into the noise loop, so it serves as a second Audio input too.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
