Description

The ACL Sinfonion is a harmonic quantizer in 42 HP: a root, a mode and a scale chosen on the panel set the harmony that three quantizer channels, a four-voice chord generator and an arpeggiator follow.

Key features

  • Three quantizer channels, their allowed notes chosen as intervals on dedicated buttons, with an optional triggered mode
  • A chord generator on four pitch outputs, with knobs for pitch and spread and buttons for the inversion and the slew
  • An arpeggiator with eight basic patterns, knobs for pitch and range and buttons for the pattern and the start note
  • A chord progression sequencer: 16 songs of 4 parts of up to 32 steps, advanced by clock, button, gate or CV
  • 88 built-in scales, 16 button presets, a 128 x 64 OLED display
  • 4 CV inputs, 2 gate inputs, 2 gate outputs and 2 pots with assignable functions, an input and output matrix
  • Everything saved automatically; any number of Sinfonions linked into one with Harmonic Link
