In the world of modular synthesis there are certain names that command veneration and respect, like Moog, Buchla, Doepfer, and Serge, but there are others that inspire the kind of fizzing delight and excitement that simply won’t leave you alone until you’ve filled your bedroom and half the hallway too. Mutable Instruments have been making Eurorack modules in that latter category for almost a decade, and now Clouds - the texturizing module which sold like crazy in hardware and became a firm favorite of enthusiasts around the world - is available for Softube Modular.

A long-awaited addition to the Softube Modular platform, the 4ms Pingable Envelope Generator opens up a vast array of possibilities beyond the basic ADSR envelope generator included in the core Modular package.

With the 259e, the answer is - pretty twisted. A coveted dual oscillator module now available for Softube Modular, Buchla 259e Twisted Waveform Generator is the first-ever officially licensed plug-in version of a Buchla product. While the unit can be used for traditional synth patches, its unusual inner workings makes Buchla 259e excel at metallic, cold, harsh, digital and screeching sounds.

A deeply useable and versatile module by USA West Coast synth specialists 4ms, the Spectral Multiband Resonator (SMR) for Softube Modular can process audio like a classic filter bank, ring like a marimba when plucked/struck, vocode, re-mix tracks, harmonize, output spectral data, quantize other oscillators to scales and much more. It's colourful, complex, and musical, infinitely expanding what is possible to achieve with Modular.

It's time to take control of time itself, with the Doepfer A-188-1 Bucket Brigade Device for Softube Modular. Our officially licensed software version of the BBD module represented a new challenge in terms of component by component analog modeling, and the results were worth the effort.

By passing your signal along a line of capacitors, the BBD delays your sound in time, but also degrades it with high-frequency loss and additional noise (as well as noticeable sample-rate reduction and aliasing at high delay times). This creates a warm and dirty effect, much sought after in the mid/late '70s, and still loved.

Ever since the low pass gate was invented by Don Buchla for his 200 series instruments in the early 1970s, low pass gates have been heralded for their ability to add a lifelike and organic response to modular synth patches. They work by applying an envelope to a low pass filter with its 0-voltage cutoff frequency way below audible range, so when the envelope is down, the 'gate' is closed. As a note decays, its high frequencies die soonest – just like most acoustic sounds.
