Pittsburgh has released a neat and perfectly formed bucket brigade “Analog Delay Unit” taken straight from the Lifeforms Voltage Lab modular synthesizer.
Lifeforms Analog Delay Unit
Oh, the satisfaction you get from using something simple that sounds fabulous. The Analog Delay Unit is a wonderfully easy module that will bring the warmth and depth of analog echoes to any system. Two sliders; one controls the delay time, the other the feedback (or number of repeats) and then a nice knob for the wet/dry mix. Ridiculously easy and instantly rewarding. I don’t mean to labour the point but delay modules seem to have taken a bit of a turn into the complex and fascinating, and that’s really cool, but sometimes you just want some echo.
The Analog Delay uses a pair of 4,096 stage BBD chips to generate the voltage controlled delay signal. This is not about the long meandering delays of digital units this is audio signals feeding through a chain of 8,192 capacitors for up to 340ms of delay. But it’s a delay that comes with the warmth and variation normally associate with tape. You can push it a little further with CV control up to 465ms but with some reduced fidelity and high-frequency clock noise bleed.
You have some attenuation on the input signal and a CV input on the delay time which can go positive or negative.
That’s about it, for $199 in 6HP, a completely useful analog delay module.
