lame for encoding the SooperLooper’s wav output to mp3.

I ended up just using echo to issue commands directly to /dev/ttyUSB0

node-serialport was initially used to control the display, however when compiling a custom kernel (more on that later) I could not get it to compile correctly.

onoff to control LEDs and listen for button presses.

node-OSC sends commands to SooperLooper.

Jack takes care of all audio routing from the sound card to SooperLooper and back.

Here are the electronic guts of the finished instrument: the Pi is driving buttons, LEDs, a display, those speakers on either side, the pickups and a fair old whack of software.

I am full of ideas (for other people’s pianos – mine’s staying un-hacked). I learned something new today: you can buy what are basically super-long guitar pickups (as seen in the picture above), which will work in pianos. With a Raspberry Pi, some magnetic pickups, and the open-source Sooper Looper (which I am downloading as soon as I have finished writing this post), Mike and Sean from MajorMega hacked an old upright piano into an instrument that can loop up to four separate tracks, and then upload your results to the internet to be listened to when you get home. A dotted quarter rest lasts for 1 1/2 beats, a dotted half rest lasts for three beats, and a dotted whole rest lasts for 6 beats.Music hacks are my favourite hacks of all, and this one had me bounding around the office with the video below playing on my laptop so I could share it with people yesterday. Like notes, rests can also be dotted, increasing their value in the same way.

Same thing applies to notes on ledger lines. In terms of notation, if the dotted note is on a space, its rhythm dot also goes on the space, but if its on a line, the dot goes on the space above.

For instance, a double dotted half note has the value of 2 beats plus one beat, plus half a beat, giving you a total of 3 1/2 beats.įor a double dotted quarter note, the duration is one quarter note plus one eighth note plus a sixteenth note, or 1 3/4 beats. But what if there are two dots after the note? In that case the duration of the note is increased by a total of 75% (which is 50% for the first dot and 25% for the second dot). Here’s a large image showing eighth, quarter, half and whole dotted notes.Īs we’ve seen, a single dot increases a note’s value by 50%. So a dotted half note lasts for three beats. Two beats plus one beat equals three beats.

In common time a half note equals two beats. So a dotted quarter note lasts for one and a half beats. One quarter note plus one eighth note equals one and a half beats. Half of that length is one eighth note beat.

Hold the note for its duration plus half of its original length. If it last two beats the dotted note lasts 3 beats. In other words if a basic note lasts one beat, the corresponding dotted one lasts one and a half beats. A dotted whole note is equal to a whole note (semibreve) tied to a half note (minim).

A dotted half note is equal to a half note tied to a quarter note (crotchet). A dotted quarter note is equal to a quarter note tied to an eighth note (quaver). A dot increases the length of a note by one half its value. Dotted notes are notes with a small dot written after them.
