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
- Width: 14HP
- Depth: 35mm
- Power: 66 mA +12V / 49 mA -12V

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
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 at info@signalsounds.eu if you have questions.
