The Inception of Keyboard Instruments
Is every new technological development just a deeper dream state?
Sound is basically waves of pressure changes. The exact definition is more complicated, but essentially we perceive sound because our ears decode the frequencies of oscillating movement of particles in gases, liquids, and solids. There are many ways to generate sound waves, such as plucking guitar strings so they vibrate, or hitting a membrane like a drum head.

Pipe Organs
A long time ago, people discovered that sound could also be made by blowing air through a pipe with a opening on the side, thus inventing the whistle. They also found that a range of tones could be produced by assembling a group of whistles with varying lengths and diameters. Then they attached a controller (called a keyboard or manual) so that one person could “play” this collection of pipes. Their invention is what we now know as the pipe organ.
At the start, pipe organs had only one timbre – a basic whistle sound, but over the next several hundred years, smart inventors and musicians made improvements in the technology. They found ways to emulate lots of other instruments, like brass, woodwinds, percussion, and even human voices. Their hope was to fully replicate those real life instruments.

As features were added, pipe organs evolved into enormous, elaborate, and expensive installations, increasingly more complicated to play and maintain. While these pipe organs were truly amazing inventions, capable of creating complex and beautiful music, they were actually quite poor emulations of the real life instruments they were intended to replace.
Still, we humans are adaptable and we fell in love with the sound of pipe organs, learning to appreciate the instrument for what it was, not what it wasn’t.
Electric Organs

Eventually, we discovered electricity and began to harness its power to create electromechanical instruments. Creative minds developed things like vacuum tubes, tone wheels, and transistors. Companies like Hammond and Wurlitzer implemented tone wheels to generate sounds approximating a pipe organ.
However, similar to the pipe organ, this new technology was a brilliant invention that poorly emulated its predecessor. These new organs were affordable alternatives to pipe organs, so in spite of being a bad imitation they became popular with smaller houses of worship. Traveling musicians took advantage of the portability of these smaller organs too, making their sound common in popular jazz, blues, and rock music.
Once again, our ears grew accustomed to the sound of the imitation, developing an affinity for the quirks of its particular aesthetic.

As the march of progress continued, electronics became smaller and more powerful. Engineers found ways to replace the delicate mechanical parts in electric organs, which were subject to wear and tear, with completely electronic sound generators. Lightweight, all electronic keyboard synthesizers used a variety of methods in attempts to replicate the sounds of their heavier electromechanical ancestors.
But just like before, history would repeat itself. The new emulators were incredible technological achievements that fell short of their goal of replacing the old technology. Though they lacked the ability to fully replicate the previous generation, they possessed attributes that eventually found an audience of connoisseurs that valued them not just in spite of their glitches, but because of their unique properties.
Software
Today, we synthesize the sounds of the old technologies with computers and keyboard MIDI controllers. While initially computers could only crudely imitate the old masters, DSP technology is progressing rapidly. CPU speed and available RAM are no longer the main limitation factors. As the computational power ceiling continues to rise higher and higher, software programmers are able to provide increasingly nuanced emulators that can easily fool the listener into believing that the software is actually the real thing.

At this point, if you’re still reading, then you probably can see how this history correlates to the plot of the film Inception. Each new technological breakthrough has been like a deeper dream state, where the simulation moves further and further away from reality.

However, just like in the film, while each level becomes more strange and abstract, the deepest level — Limbo — actually approaches something most like the real thing or maybe even better. Today’s emulators delve into such detail and are able to control even the most minute aspects of the sound, that it won’t be long before they easily eclipse the believability of the old technology. In fact, we may already be there.
A few years ago (when the emulators weren’t half as good as they are now), a friend of mine (who has very good ears) dropped by the studio to hear a song I was working on. When the B3 organ kicked in during the chorus, he declared, “That organ sounds great. There’s nothing like the real thing!” Muwhahaha! The smoke and mirrors of software emulation had worked.

This idea of how keyboard technology relates to Inception came about through a discussion with my friend Hoss. Over the weekend we were working on the keyboard parts for our band Rudisill’s next album Take To Flight. In between takes of an organ part we marveled at the realization that the software he was using was an emulation of an emulation of an emulation — a truly strange scenario.
Follow Rudisill to hear about the new album when it is released later this year (2012).

Modern recording takes lots of hard drive space. It’s easy to eat up several GB on a song of average length and track depth. I’ve filled a drive or two already with various recording sessions, Photoshop files, and media. Over the weekend I had to pick up another drive just so I can finish my upcoming album. I went to the nearest big box electronics shop and picked up the the biggest drive with the best price. What I found was the Western Digital 2 TB My Book Studio LX. The size should be enough for the next year or so (let’s hope!) and the 
The only thing that bothers me about WD is their pre-installed SmartWare software. It’s a huge can of donkey sauce. This multi-function bloatware takes up over half a GB of space, is loaded into the drive firmware (so it cannot just be formatted away), appears as a separate VCD that pops up everytime you connect to the drive, and cannot be completely removed without voiding the warranty. The only option WD gives the user is to download two more software packages, one that updates the firmware so you can run the second package that allows you to hide the VCD. Blehhhh…
