Day 39 @ ITP: Phys Comp

Week 6
Midterm project: the beginning...

I met with Jim Schmitz today to start working on our collaboration for our midterm project. I found a pdf to the book "Arduino Music and Audio Projects" on the NYU library online and shared it with Jim who read it before we met and explained to me how MIDI works in binary code.


The first four digits of 0000 send whether or not a key or button is pushed. The second four digits 0000 send the note. (?)

In binary 1 = true and 0 = false. 

(a & b) = if one is false, then it is false

(a | b) (a or b) = if one is true, then it is true

Binary has a value of 0 or 1 and each bit after goes up in the powers of 2.
Or 1, 2, 4, 8, 16, 32, 64, 128.
1x16 + 0x8 + 1x4 + 0x2 + 1x1

Normal numbers are in the powers of 10... so ones, tens, hundreds, thousands...

A prototype of our prototype

We came up with a sketch of how we want our project to work. We had already decided on a musical instrument that would involve interactive elements using MIDI. Together we looked at materials we had to work with, and decided on an instrument which would be controlled by a sensor (most likely a pulse rate sensor attached to the user's index finger) that will change the tempo of the sounds, which in turn will be altered through push buttons that add effects or otherwise change the sound. The sound information will be generated through MIDI from the Arduino into a software instrument using an audio editing program (such as Logic or Ableton) or using Hairless MIDI (which was mentioned in the book "Arduino Music and Audio Projects.")
