The Circadian Rhythms, is a professional performance gate sequencer in Eurorack format. Sitting at the center of your system the Circadian provides triggers and gates to all your drum modules and percussive sounds as well as clocking your other sequencers with exceptional timing accuracy. Each channel voice can be programmed directly from the intelligent, eight-channel, 512-step master gate sequencer designed for composers looking to make music on the modular and perform live. Building up from basic step programming, multi-channel patterns of musical phrases can be repeated, looped, chained, muted, and manipulated in real-time, and, most importantly, all through a simple, clearly labeled menu-free interface.
Led Grid
Built around 72 buttons set as a multi-color illuminated 8×9 array, Circadian Rhythms displays both note data and settings in a clear and precise manner. It takes only one click to switch to vertical view, turning the grid into a set of programming and real-time playing functions like Mutes, Loops, Swing, Fills, Copy and Paste, Grouping, Randomizing, and Manual drum-machine-style trigger entry. Activate any of those functions with only a button press or two.
Using an array of multi-color, illuminated buttons and innovative grid views provides a highly functional live performance sequencer with a beautiful, glowing appearance that will look amazing on stage for both performer and crowd. As a master controller, the heart of the modular synthesizer, the Circadian Rhythms generates high precision clock and reset signals for all the other sequencers and devices in the system and can also act as a high precision bridge for DAW synchronization.
Clock
Inside the CR ticks an extremely precise clock with jitter and latency measured in mere microseconds for the ultimate feel of the groove. The four modes of clock sync make interfacing with other modules, hardware, or software simple. Whether driving a large Eurorack system or synced to a DAW, the groove always remains tight.
Under the Hood
When state of the art chip technology, musically driven firmware, and professionally engineered hardware design all come together in one electronic device, the result is a music sequencer with unparalleled specifications. Starting with a powerful, precise sequencing engine that has superb feel for the groove, add internal functions that automatically balance performance and smooth user interface operation, and finish with outstanding low power consumption placing minimal stress on power supplies even at maximum output, Circadian Rhythms has a design focused on the requirements of the most dedicated musicians and composers. Long-time pros will immediately feel a machine made for their needs, while newcomers can instantly dive into next-level programming and performance.
SyncBus Technology
The Tiptop-Audio-designed SyncBus enables the CR to connect to any number of other SyncBus devices with the highest possible level of synchronization. A SyncBus master directly injects its core clock and running status into every connected unit so they work seamlessly as one device. Hook up two CRs to make a 16 channel device or add a Trigger Riot (or three) to the mix for further experimentation. Plus, the connection is done behind the panel so there is no need to patch anything together.

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 15:00 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.
