cropped SINFONION by ACL front

Unleash the power of your modular system with the Sinfonion. Not only is the Sinfonion the most complex and versatile quantizer, chord generator and arpeggiator in Eurorack format, it is also a very musical module and fun to use. It has been designed and programmed by Mathias Kettner and is produced by Audiophile Circuits League in Berlin.

The Sinfonion is designed for those musicians that do not want to be limited to creating “sound sculptures” or rhythmic grooves with their modular instruments but want all their fabulous VCOs and other voices to play together in the most musical and polyphonic way – may it be harmonic or even disharmonic on purpose. The Sinfonion comprises of three independent quantizer channels, a four-note chord generator, an arpeggiator and a complex progression sequencer in one. Thanks to a vast array of buttons and knobs placed around a sharp OLED display, it is easy to use and come up with musical ideas.

Sinfonion a control center of your modular system

With a total of 8 pitch outputs, 4 gate outputs, 11 CV inputs, and 9 gate inputs, it offers a large number of controls. Its plethora of buttons makes it an actual instrument you can play. Furthermore, the Sinfonion features an expansion port to add modules and expand functionality in the future. The three quantizer channels provide direct access to harmonic scale notes via dedicated buttons per channel (Root, 3rd, 5th, 7th, 9th, 11th, 13th). The buttons are made for jamming, controlling the sequences on the go. A fast processor allows quantization times below 1ms.

Chord, Sequencer & Arpeggiator

A chord section generates four pitch outputs, allowing to create four-voiced chords. It offers a lot of options directly accessible from the front panel. Thanks to dedicated knobs for pitch and spread, buttons for selecting the notes chord inversion and optional slew, you can get the chord you are looking for in no time. The arpeggiator section features 8 different patterns, dedicated knobs for pitch and range, and an array of buttons for selecting the scale notes and the pattern (Up, Down, Up/Down, Down/Up, Baroque, Octaves, Brownian, Random).

Creating your Own FX banks

There are plenty of videos on YT about FX-Aid, but one of its best features is the ability to pick your own favorite effects from a huge library that frequently grows. You can use a web-based editor (, but you can also download a desktop version. After creating a firmware audio file, you can then ‘play’ the firmware into the module.

Use your laptop/phone for best results because the module expects line-level sound, and make sure it’s in airplane mode to avoid unwanted sound effects. The audio goes into the FX-Aid CV input or the FX-Aid XL SRR input. You can switch the module to upload mode by pressing the two little buttons for at least 10 seconds. Have fun! The module does not ‘brick’ when something goes wrong, you can simply press any button and try again. Have fun!

Weather Drones 1.5

Weather Drones started as a DIY project a few years ago but is now available as an affordable prebuilt module. Weather Drones is a great module for creating evolving drones, textures, and soundscapes, but it also responds to pitch very well. It has a mix out for the final result, but it also has separate noise, triangle, square, and fold outputs. It has a built-in low pass filter that can be modulated with the internal ‘helper’ oscillators which also accepts external modulation.

The final output has a ‘spread’ and ‘wavefolder’ knob to create all kinds of sounds, but its digital core really needs some external FX processing. Version 1.5 adds a built in VCA that can be modulated with an internal AD envelope generator.
