ACL Sinfonion

Over the years, you have build a big modular system, containing lots of oscillators, filters, voices and sequencers...
and now you would like to play all these together without ending in a cacophony?! Sinfonion is the answer!

After a long time of development and refinement, Mathias Kettner is proud to present his creation, which could be finalised in cooperation with ACL.

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.

The Sinfonion is meant to be the 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 make 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.

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).

All these sections are under control of the Chord Progression Sequencer. It is the brain of the Sinfonion and is operated easily thanks to the display. You can change the root, degree and mode by simply turning the according knobs. It enables the creation of 16 songs with 4 parts each, and 32 steps per part. This comprises the sequencing of chord voicings, octave switches and scale note selections.

The Sinfonion puts an unbelievable sequencing power at your fingertips! Harmony in it's purest form! It will bring your music to the next level!
