The Logic of Logic
Thursday, May 21st, 2009Sometime in the mid 80s I bought one of the first midi sequencers to come out. It was a marvel of invention at the time and could literally record 160 midi notes in sequence from a synthesizer and then play back the pattern at practically any speed maintaining the pitch of the instrument as the tempo was increased. Remember that tape always moved the pitch up the faster the tape was played, hence the Mickey Mouse effect. It would only work for one instrument at a time and so we would usually use it for a bass line since it was monophonic, meaning that it could only play one note at a time (no chords). After 160 notes it ran out of memory and either repeated itself or stopped playing.
It was the size of a large microwave oven and made out of metal with many plastic buttons and little LED lights. We (my engineers and I) used to program it and then turn all the lights in the studio out and excitedly watch the lights run their sequence as the bass line played. We were kids with a new toy.
One day we decided to take it apart and see what was inside this marvel of engineering. We opened the metal case expecting to see it crammed full of gears and widgets and wiring only to find nothing but empty space. There, at the bottom, sat one computer chip half the size of a vanilla wafer that, of course, ran the entire machine. We looked at each other in wonder in our first real life experience with digital chip technology.
