Rakarrack has a GUI written in FLTK. It was my earliest adventure with guitar effects and DSP (ca 2008); it ran on a potato laptop and still kept up, which made the whole setup actually viable for spontaneous jam sessions at other people's places. Good times. - Source: Hacker News / 5 months ago

I was messing around with a guitar, a USB interface, and a software called https://rakarrack.sourceforge.net/ (I don't know if it is available on windows) and it was a lot of fun! You could scroll through the presets and make the guitar sound like all kinds of things! Definitely worth tinkering with. Source: about 1 year ago

If you haven't tried it, I love this, makes songs seem like one forever long song! https://eternalbox.dev/jukebox_index.html. Source: over 1 year ago

This is only one song, but did it have a similar UI to The Eternal Jukebox? That one also uses a big circle layout and was big on Tumblr back in the day. Source: over 1 year ago

Yes! I’m so glad I saved this link! So this particular website takes a song and makes it last forever. Well it mixes it up and just keeps it going. Just check this out it’s amazing. I don’t know who made it or where I saw it on here but dang it’s worked for pretty much every song I’ve tried. Https://eternalbox.dev/jukebox_index.html. Source: over 1 year ago

I like The Eternal Jukebox. It perpetually mixes a single song so no play through is ever the same. Source: over 1 year ago
