Manufacturer's description
Future Sound Systems are proud to release the Cyclical Function Generator ENV1 Eurorack module to the world. The CFG was designed preliminarily for Cric, yet stands as a fully-featured function generator for modular systems too. Each ENV1 module features two CFGs, with each featuring:
- an Attack and Decay stage
- different shape modes for the two stages (linear, exponential or logarithmic)
- modulation over each stage's time
- a Pulse output, switchable between an End of Decay pulse or a Comparator output which goes high when the CFG slope is above 50% of its total range
- three modes of operation - looping, attack/decay and attack/sustain/decay
- a Loop input, coupled with jumpers on the rear of the module to also force each CFG to trigger on an incoming pulse to this input
The CFG has been designed to cover a wide time range for both attack and decay stages, with their minimum times resulting in oscillations in the kHz range, up to their maximum times of several minutes per stage for a single cycle.
The Pulse source derived from each CFG can be switched between End of Decay (EoD) or Comp. In EoD mode, a brief trigger is sent as soon as the Decay stage has completed. This can be used to chain several CFGs together in a sequential fashion. Meanwhile, in Comp mode, a comparator sends a pulse which is high as long as the Slope is above the midpoint of its range, and low when it is beneath this midpoint. With Attack and Decay set to produce a perfectly
triangular slope, a 50:50 square wave will be generated in Comp mode.
The CV Depth attenuverters follow the law that, for a positive voltage source at the corresponding destination, negative settings (anti-clockwise from 12 o’clock) reduce the stage times and positive settings (clockwise from 12 o’clock) extend the stage times. Without a jack present at the corresponding input, the CV Depth control becomes a fine tune for each stage, which is particularly useful if using the CFG as an audible oscillator.
As with many "West coast" inspired function generators, each CFG can cover a plethora of use cases:
- low-frequency oscillator
- envelope generator
- frequency sub-divider / sub-harmonic generator
- audio oscillator
- pulse-train generator
- gate/trigger delay and monostable

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.
