Constellation is all about rhythm. It is an 8 channel pattern generator that works by combining multiple dense and sparse patterns to create long, complex and musically interesting trigger and gate rhythms. Constellation takes a "parametric" approach to rhythm - there is no explicit step sequencing on the module, rather the rhythms are defined by euclidean (and more) parameters that build the rhythm mathematically.
Constellation aims to evolve the concept of euclidean rhythms far beyond the useful but repetitive patterns we often think of when we hear the term "euclidean rhythm". We accomplish this by combining up to 8 individual euclidean patterns of different lengths and density. Each pattern may provide only a small component of the final output, but together create immensely musical and varied rhythmic material over a very long time frame - up to 999 steps! If each of those steps are 1/16 note in length at 120 bpm, that's a full 2 minutes of explicitly defined, yet non repeating rhythmic material.
In addition, Constellation's parametric approach allows any of these parameters to be modulated with CV through one of 8 freely assignable CV inputs. CV modulation introduces further ability for Constellation's rhythmic output to vary over time. Paired with a Maestro or Navigators, hours of interesting morphing rhythms are possible without the need for tons of step programming or the uncontrollable chaos of a purely generative approach.
When writing music, rhythmic interest is often built through the combination of repeating and non repeating elements that work together to anchor the overall feel but also keep the ear free from boredom over the duration of the piece. We feel that Constellation provides a unique set of tools to accomplish this goal and achieve rhythms that are intentional, unexpected and exciting to use as the foundation of your compositions.
Constellation Features:
- 8 channels of trigger/gate generation
- 8 Euclidean patterns per channel each with clock division, burst, ratchet and probability
- Combine multiple dense and sparse patterns with logic to arrive at complex, musical rhythms
- 8 freely assignable CV inputs to modulate pattern parameters for continuously evolving rhythmic movement
- Per channel clock division and multiplication to achieve a wide range of true polyrhythms
- Save and load channel settings from up to 20 save slots per bank and up to 999 banks
- Manually play save slots like a keyboard in live mode
- Robust internal and external clock options to sync tightly with all your other gear

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, 'next working day' shipping is free if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.

Shipping to mainland EU typically costs 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 DPD, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce 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 aim to dispatch the same working day if we get the order before 16:00. 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 the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.

Saturday/Sunday shipping

If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.

International 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.

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.
