GREAT WALL is a harsh noise / harsh noise wall synth i've been working on for a couple months or so. it attempts to provide an environment for anybody to explore a huge spectrum of harsh noise sounds, which is usually somewhat obnoxious to do on a desktop computer. "feedback" doesn't really exist in computers the way it does in the world of audio hardware, and since feedback is so much of what makes a lot of these sounds what they are, it can be frustrating to attain them without investing in gear.
rather than employ much actual feedback (latency is involved when doing so, so its uses are limited), GREAT WALL simulates certain aspects of feedback and the amplification of audio circuits through a huge web of oscillators, filters, delays, and clippers. just about every one of the controls on it is a macro control adjusting many internal parameters, and a huge number of the controls also have influence on one another. there's not really any use explaining what any of them do as a result. the main "generator" can be patched out as a controller for some of the other functions on the synth, which makes for several additional layers of exploration.
it can also attempt to use the filters to track the pitch of your midi input (which usually just controls the generator rate), but the use cases for this will probably be fairly few and far between.
while there are many ways to push it into relatively textureless screeching, i've tried to tune all of the controls so that most of the settings are interesting. this is a little difficult when each of the controls is doing so many things, but i feel that i've mostly succeeded in narrowing it down to a sweet spot; it's very easy to quickly get bouldery noise walls, metallic scratching and screaming, and most things in between.
