Quick MIDI Synth Guide

Plug your MIDI controller into a USB port.

Run aconnect -o, and look for your MIDI controller in the output:

1
2
3
4
5

$ aconnect -o
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 20: 'AKM322' [type=kernel]
    0 'AKM322 MIDI 1   '
The controller’s client number here is: 20

Run aseqdump -p 20 (replace 20 with the client number) to verify it is working

Then: 
1
2
3

$ sudo apt-get update
$ sudo apt-get install fluidsynth fluid-soundfont-gm
$ aplay /usr/share/sounds/alsa/Noise.wav

This last command should make a noise through your speakers.

Then, for my computer, the following setup seems to run best:



$ fluidsynth --audio-driver=alsa --gain 3 -r=22050 -c=16 -z=64 /usr/share/sounds/sf2/FluidR3_GM.sf2
In a second terminal, run:

1
2
3
4
5
6
7
8

$ aconnect -o

client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 20: 'AKM322' [type=kernel]
    0 'AKM322 MIDI 1   '
client 128: 'FLUID Synth (1179)' [type=user]
    0 'Synth input port (1179:0)'

In terminal 2:

1
2

# xx is your midi controller, yy fluidsynth
$ aconnect xx:0 yy:0

Base64 decode to file

The internet sometimes sucks. I spent about 20 minutes searching the internet for an easy way to decode a base64 file in linux. Shouldn't be that hard. In fact, there is a base64 command. But fuck me, I sure couldn't get it to work with the file I had (which was supposed to decode into a .jpg). There is tons of nonsense about the theory and some stupid unhelpful web applications, but no practical examples. That is, until I stumbled upon this little gem - which gave me exactly what I wanted. perl -MMIME::Base64 -ne 'print decode_base64($_)' < file.txt > out A one-liner in Perl (of course). The fact that this info was so easy, yet it was so hard to find pisses me off. I'm sure there are other ways to do this. In fact, if you know of other ways to do this, then please leave me a comment telling me how. I hate when good info gets buried under the load of crap clogging the internet tubes.

Swiftboating from the Left - Paul Harris's "The Real McCain"

The teaser of Harris's article is this: "To his fans he's a lovable patriot with a maverick streak. But to his critics he's an anti-abortion Creationist who surrounds himself with religious extremists. Paul Harris uncovers the dark side of John McCain" I'm an Obama supporter, but merely from the teaser I already want to run to McCain's defense. An "anti-abortion Creationist"? Really?? Bullshit. This is like the Obama "Terrorist fist jab" teaser on Fox - its utterly stupid. And provably so from a not-to-long ago debate: The rest of the article is blindingly obvious in its propagandistic machinery. Briefly mention a few reasons someone might think he's not such a bad guy (make sure to put it in the subjunctive). Claim this is all a facade to "propel him to the Oval Office". Expose the "dark side" that "lies behind his public mask". Pull out any dirt you can and start slinging. Precisely this formula is ...
