The idea for the discussion first came up on this topic here: Live recording, april 25th 2017 - much MI going.
Everybody seems to have their own favourite excitation signals for Rings. I personally really love using field recordings to create long evolving drones and short percussive lo-fi samples (usually using the GrandPa), often combined, so I can have a base drone and add some percussive elements to it.
Another things I like (and which surprised me somehow as well) was to use a square-wave-based chaotic oscillator to excite Rings in “sympathetic string” mode. The resulting sounds mantains some of the original excitation sound’s properties, but of course is heavily shaped by Rings, so the result is this kind of brassy sound, which I really like. Works great with the Hexinverter Jupiter Storm (but you need to find the sweet spot).
So what are your favourite excitation signals (or patching tricks) with Rings?
