Push (or Pulse) the Envelope
Snappy, classically analog envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons —then double it—now you've got Tangrams.
Get In Shape
Tangrams, like our Dual ADSR before it, is a dual analog core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, we have added a voltage-controlled pulser circuit to link the triggering of two envelopes – allowing for delayed one-shots, cycling organic envelopes, and more. In addition, we’ve added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you’d like to envelope – freeing up your other VCAs.
The Pulser
The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.
ADSR + VCA Features
- Dual Analog ADSR envelopes with digital gate Pulser for trapezoid shapes
- Pulser stages P1 and P2 can be selectively routed to trigger each ADSR via panel switches
- Three timing ranges: (FAST: ~5 seconds, MED: ~35sec, SLOW: ~1min A/D times)
- Retrig input (allows re-triggering of the envelope if source gate held high)
- VCA input can be used to dynamically control the respective ADSR output level (bipolar) or to process signals to be modulated in amplitude by the ADSR.
- Manual GATE buttons for each envelope
Pulser Features
- A pulse is made of individually controllable T1 and T2 stage lengths
- CV control over T1 and T2 time
- Pulser can be one-shot (SINGLE) or repeating (CYCLE)
- PULSE output has a switch to select P1 or P2 as the source.
- Pulser stages P1 and P2 can be selectively routed to trigger each ADSR via panel switches
- START trigger input for starting/restarting the Pulser sequence
- Manual GATE button to trigger the Pulser sequence

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.
