Overview

The core idea for KALI is that complex and musical sonic patterns/beats can be created naturally by combining a modulated audio source with a time-domain (i.e. a delay) effect, especially if the modulation is synchronized to the effect.

Kali has two major sections to facilitate this.

  • 32-bit (Float) 48000khz Stereo Time Domain FX Processor
  • 6 x Bipolar 12-bit CV Outs (Approx -7v to 7v*) + 2 x Clocks

The L and R delay times are the main timebase to which everything else is synchronized; the rates of everything else can be adjusted in multiples of this time, both independently and (with the lfo rate knob) all at once.

* Not factory calibrated so there is some variation. Basic digital tuning of this range to balance + and - range is on the way.

Specs

Kali is built around an Electrosmith Daisy Patch Submodule, an embedded development platform (STM32 H7 @ 480mhz) with a high fidelity PCM3060 codec.

Audio input/output is 48000khz @ 24-bit, internally 32-bit (floating point). Input gain (on PCM3060 itself) can be adjusted from -100db to +20db.

Because of the generous SDRAM on the Daisy Patch Submodule, these delay lines have a maximum time of roughly 150 seconds per channel (we cap it at 10 seconds in most modes as that has proven to be a good generally useful range, but this maximum can be changed).

CV outputs are all 12-bit, and lowpassed to mitigate aliasing. Output range is -7v to 7v, most LFO modes can be toggled between bipolar and unipolar output. 

Synchronization
Sync in by pulse/trigger or TRS MIDI In (A or B, thx to lpzw modules https://leipzigwest.org/).
