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
Specifications
- Module width: 14HP
- Module depth: 40mm (including ribbon cable) behind 2mm FR4 front panel
- Current draw: +90mA, -70mA
- Function voltage range: 0V to 10V
- End of Decay pulse volage range: 0V to +10V
- Comparator pulse voltage range: 0V to +5V
- Minimum threshold for Trigger and Loop voltage inputs: +2.5V
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.
