yes, it's a delicious way to make guacamole. but it's also the name of a plugin that'll fuck your shit up good. avocado is only available as a js effect, which means you'll need to download reaper to get it. but since reaper is available for a free 30-day trial, has a very relaxed purchasing scheme, and doesn't rape your computer with a bunch of bullshit that takes forever to install and uninstall, there's no reason not to give it a shot. but that's for another thread.
avocado is a glitch plugin, or, as many people fondly say, an fsu plugin. for the uninitiated, "fsu" stands for "fuck shit up," since that's what these plugins are generally built to do. they make normal, pretty sounds sound completely unrecognizable and often produce unpredictable results. there are tons of fsu plugins around, many of them available for free in a place like kvr's database. i've tried out lots of them over the years, but i guess i'm too tame in my fsu tastes, so few of them really caught my fancy. one that does, though, is avocado (you can see a thread about avocado here).
there are lots of plugins that will store your audio in a buffer, mangle it up someway and repeat it back to you later, but to get the most out of them, you have to be modifying the parameters in real-time. with trombone, though, that's not really possible since your hands are busy doing something else. the cool thing about avocado is that it has up to 16 buffers that it records to and plays back from in random order, so if you improvise along with it, the audio that comes back out could come from 100ms in the past or 10 seconds in the past or anything in between. this keeps you on your toes as you're improvising and provides a "partner" who responds somewhat to your playing. it also has pitch, repeat, and other parameters to mangle up the audio in random ways.
here's some free improv i did with it. mangled plunger sounds sound particularly great, so i used mine.
