The DH-ADSR is exactly the same circuit as the original Model D envelope and therefore features the same contour shape and retrigger behaviour, but with the addition of a release control. However, they have also added a pulse delay and pulse stretch circuit, along with a re-trigger facility (both of these can be switched out of circuit so that the envelope is a simple ADSR unit).
The addition of pulse stretching and retrigger makes it into an LFO module and it can perform in a similar way to the EMS Synthi A and VCS3 Trapezoid generator, with a variable delay between each trigger and a variable "on" time - however it can also have full ADSR envelope on each retrigger too!
Notable Features:
- PREDELAY - This control determines how long (up to 10 seconds) the start of the envelope is held off, after a gate is received. This ability to delay the onset of the envelope is especially useful when used in conjunction with a standard ADSR: With both envelopes receiving the gate simultaneously complex envelopes can be produced as the DH-ADSR only starts running through its stages after the standard ADSR has completed. Once their outputs are mixed together in a mixer a single evolving envelope with multiple stages is produced!
- Use of the bipolar mixer found in the MINIMOD CV MIX-OFFSET-VCA module can enhance this technique even further, with more precise control over the polarity/offset of the envelope mix possible. Using the VCA of this module could allow for external modulation over either/both of the signals. It goes on...
- HOLD - When in Del-Hold mode (switch down) the HOLD control determines the gate length applied to the envelope, and thus controlling its length/overall shape. When the switch is up, normal ADSR action is produced.
- RETRIG - In this mode the DH-ADSR becomes an LFO, which can mimic the "Trapezoid" function of the vintage EMS designs. HOLD controls the length of the trapezoid shape, and PREDELAY allows for adjustable gaps between each repeat of the shape produced.to an LFO module and it can perform in a similar way to the EMS Synthi A and VCS3 Trapezoid generator, with a variable delay between each trigger and a variable "on" time - however it can also have full ADSR envelope on each retrigger too!

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.

| Sweden | 3–5 |
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.
