Shipping info
The ES-40 is a Eurorack format module which converts a standard S/PDIF input to five channels of expansion headers, which are used in conjunction with the Expert Sleepers ESX range of expanders (currently including the ESX-8GT, the ESX-4CV, the ESX-8CV and the ESX-8MD).

The ES-40 will connect to any audio device using the S/PDIF standard. This includes the digital audio output provided as standard on many recent Macs (more info here on the Mac connection).

The ES-40 also includes an S/PDIF output for sending data back to the computer. This output is used by expansion modules connected to the ES-40; currenty, the only such module is the ES-7 CV Input Expander.

The ES-40 is essentially an ES-4 with the DACs and CV outputs removed. Much of what has been written about the ES-4, and many tutorial videos etc., still apply to the ES-40.

Suggested combinations:

The ES-40 does nothing by itself, but forms the basis of a very configurable system. Simply add the expansion modules you need. Here are some ideas:

8 general purpose CVs - an ES-40 plus an ESX-8CV gives you a flexible, general purpose modular controller.
8 CV/gate pairs - an ES-40, an ESX-8CV and an ESX-8GT gives you enough outputs for 8 classic monosynths - or to realise that 8 voice polyphonic modular you've been dreaming of.
8 drum triggers - an ES-40 and an ESX-8GT gives you 8 triggers for your rack of drum modules, for the ultimate in sample-accurate rhythm. Add up to four more ESX-8GTs for up to 40 triggers/gates/clocks!
MIDI & DINsync - an ES-40 and an ESX-8MD form a sample-accurate, jitter-free, multi-port MIDI interface.
digital audio - an ES-40 and an ES-7 gives you two channels of 24 bit analogue-to-digital conversion to get your modular audio into your DAW.
Unlike the ES-3, the ES-40 requires particular software in order to generate meaningful output signals. Currently, the only such software is the 'ES-4 Controller' plug-in, part of Expert Sleepers Silent Way, and our Max/MSP external (see below). Note that the ES-40 works with all software written for the (previously available) ES-4 - software-wise, the two are interchangable.

Silent Way is available in AudioUnit, VST & AAX formats for Mac OS X and Windows. Use of Silent Way therefore requires a compatible host application (DAW).

A Silent Way licence is not included with the ES-40 - however, the ES-4 Controller plug-in functions in a licence-free mode, so ES-40 users are not forced to buy Silent Way. Such users can than evaluate the rest of the Silent Way suite in demo mode.

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.
