I'd like to play guitar again. Since I'm out of amps, I'd like to plug it into the computer.
Among you, does anyone do that? Is it possible to use VST effects and if so, how?
In brief, what is the state of MAO on FreeBSD?
I don't play either, but somehow ended up with a guitar some years ago and messed around with it. I just used a 1/4in to 3.5mm adapter and plugged directly into the on-board sound card line-in or mic (honestly do not remember). Was able to use a tuning and effects ports. I don't believe either of the ports I had used back then are there anymore, but audio/gnuitar and audio/gtkguitune are probably good candidates. Take things even further and use audio/jack along with audio/hydrogen.

While plugging an electric guitar directly into the line-in/mic will work (most of the time). It is risky. The line-in has a maximum safe power rating. Electric guitars do not have any sort of limiter on the maximum power they can produce (it depends on how violently you pluck/strum). You can burn out the input (and the sound processing chips) on the computer with your guitar.
I do have a guitar. I do plug it into my computer. I use my Apple iMac, so I can't really add much else to this conversation. I suggest you look at something specifically intended as a guitar input. Personally, I use an older iRig device. Please do not consider either of these links as recommendations that they will work with FreeBSD, I haven't tested either one.
