Includes the engine Greyhole and a simple lua script for control.
From the greyhole description here:
" A complex echo-like effect, inspired by the classic Eventide effect of a similar name. The effect consists of a diffuser (like a mini-reverb, structurally similar to the one used in JPverb) connected in a feedback system with a long, modulated delay-line. Excels at producing spacey washes of sound."
Greyhole was developed in 2013 as part of the DEIND project:
The project aimed to connect people with autistic spectrum disorder with the field of contemporary electronic and digital music practice. People with severe autistic spectrum disorders were invited to take part in the design process of electronic instruments. To facilitate music practice, we aimed for a holistic instrument experience rather than a modular approach in which the underlying modules of electronic instruments – interface/mapping/sound synthesis – would become too evident and possibly confuse the player too much.
Requirements
norns 2.2.3 nb: restart norns after installation
Documentation
key1 = alt
enc1 = time
enc2 = size
enc3 = damp
alt + enc2 = diff
alt + enc3 = feedback
just tried to install from maiden. getting error: init on the home screen when I try to run. did try sleeping and turning norns back on but that did not fix

glad that greyhole finds some love!
information on deind is scarce because funding ran out at some point…
the greyhole engine (as well as jpverb, an awesome sounding reverb) are written and designed by julian parker back in those days.
