Manufacturer's description

The DSS is intended as a companion for the Buchla 245/246 sequencers and other "quad" modules in Buchla format such as the 281 and 292. New possibilities for performance and composition arise from the ability to dynamically route multiple sources to multiple destinations without repatching.

The main I/O is bidirectional, meaning that the module works as a 4:1 multiplexer or a 1:4 demultiplexer. Patch up to four signals to the inputs labeled 1-4 and they will be sequentially routed to the common I/O jack. Alternately, patch one signal source to the I/O jack and it will be sequentially distributed to the 1-4 jacks.

Each half of the module has its own independent loop length (from 1 to 4 steps) and sequencing mode: forwards, backwards, forwards and then backwards (pendulum), or random. The SC (Step Change) output generates a trigger whenever the sequence length is changed, which is useful for synchronizing the upper and lower halves of the module or communicating state changes to other modules. The analog CV addressing input (ADDR) bypasses pulse-based control and allows an external CV source to select which step is active, similar to the "analog" CV input on the Buchla 245/246.

Expanded control and sequencing options make the DSS one of the most fully-featured sequential switches available in any modular format. Every aspect of the switching schema is accessible, facilitating patches that were not previously possible in the Buchla ecosystem.

Specs

  • 4:1 (multiplexed) or 1:4 (demultiplexed) switching of audio or CV
  • Variable sequence length (1-4 steps) with voltage control
  • Variable switching mode (forward, reverse, pendulum, random) with voltage control
  • Step addressing via clock, direct selection, or external CV
  • Extensive pulse I/O for synchronization with external modules
  • Width: 1PU
  • Depth: 46mm

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.
