Description
Audrey II Touch excites a feedback loop to create drifting drones, and it can also be driven by external audio (left input channel) as an effect on drum loops, melodies or voice. Knobs set the excitation threshold, input gain, dry/wet, reverb size and low-pass and high-pass filters, and pads P03 to P09 excite different frequencies. The repository includes a manual with the MIDI CC map and a faceplate design, and Synthux sells the matching Audrey II Touch faceplate separately.
Install notes
Flash AudreyTouch.bin from the latest release with the Daisy Seed web programmer (flash.daisy.audio) or Synthux's firmware page. The README advises starting with the knobs fully counter-clockwise and raising the excitation amount and input gain slowly.
