This is a ~5 min segment from a recent recording session of an atonal ambient/drone patch, inspired by Jaap Vink’s ‘screen patch’ explorations. New territory for me, been trying out feedback patching for awhile and this is a first attempt in doing one on this style. The sound source is ring modulated feedback created by patching a handful of Eurorack modules together.

The key modules are a Doepfer BBD delay, Make Noise Mimeophon, Make Noise Maths, Make Noise Rxmx w/ Fxdf, and Mutable Instruments Blinds. Altogether, a simple "record head / playback head" feedback loop is created that slowly builds by itself, and using Maths to suppress/compress the signal by acting as an envelope follower that controls the overall patch amplitude.

Blinds is patched as a ring modulator, and Rxmx/Fxdf stand in for the 'third octave filter' suggested in the original Screen Patch. This allows the feedback to be processed through 6 bandpass filters, including being able to scan through one or more filter bands. 

I also added another multi-mode filter, wave folder, and through zero FM VCO into the patch, allowing for more timbral range and ending up with a metallic resonance that I was pleased with.

If you're interested, check out Jaap Vink's work in the 1970s at the Institute of Sonology in Utrecht, exploring ring modulated feedback patching with the 'screen patch'. More on the process here: https://www.youtube.com/watch?v=X_Bcr_HS9XM
