sip4: cricket v. space invader

by Larry Dunn, August 6, 2020

In week four of Synth in Place, the online course in DIY synthesizers taught by Kirk Pearson of Dogbotic sound labs, in collaboration with Thingamajigs, we focused on the basic components and technology of commercially produced music synthesizers, and we looked at plans for making two simple synths: one that sound like crickets, and one that can replicate the sounds of 1980s Atari games like Space Invaders.

Our inspiration this week came from Thaddeus Cahill’s prescient 1897 invention, the Telharmonium. This awesome contraption was a synthesizer long before the invention of synthesizers, music amplification before the invention of amplifiers and loudspeakers, a music streaming service long before the internet. Sadly, the Telharmonium was never a commercial success, because it required the nascent telephone network for transmission services. But the demand for telephone service grew so rapidly, that there was no available bandwidth. However, its concepts didn’t disappear completely, as they led directly to development of the Hammond organ. And where would jazz, and rock, and church music be without that?

Breaking down the inner workings of a commercially produced music synthesizer was a revelation for me, as I’d never put much thought to how they work. I’ve just always been content that they make cool sounds. As an introduction, we fist learned that all the commercial synthesizers out there are using the same fundamental technologies and components to synthesize sound, whether those sounds are in the realm most people would call music, i.e., imitating the sounds of acoustical music instruments, or less readily recognizable sounds we’re more likely to hear in the experimental music realm.

We also learned that there is an east-west divide in the synthesizer world, not in underlying technology, but in the nature of the human-to-machine interface, the mechanisms the operator uses to elicit sound from the electronic beast.

East coast synthesizers typically provide a primary interface in the form of a piano- or organ-style keyboard to play the instrument, along with various knobs and switches to customize the nature of the sound. The epitome of this east coast style are the Moog synthesizers, the name that many people think of when the topic of synthesizers comes up in conversation. Robert Moog (1934-2005) was an engineer, not a musician. So he spent a lot time with musicians when he was designing his device. His objective was to make the Moog Synthesizer something musicians would find interesting and easy to play, thus, the keyboard interface so you can play it like a piano or organ.

Moog presented the first public live demonstration of his synthesizer in 1964 at the Audio Engineering Society’s New York convention. A 2014 video made by Moog’s company looks back on that day and the legacy of the founder’s creation.

Soon thereafter, it was clear that the Moog Synthesizer was an instrument musicians could and would actually play, to amazing effects. Composer and performer Wendy Carlos blazed the trail for the possibilities of the Moog in the classical realm with her 1967 release Switched-on Bach. And Keith Emerson, of the power trio Emerson, Lake & Palmer, rocked the pop world with his Moog break in bandmate Greg Lake’s Lucky Man, changing pop music forever.

Stay tuned.
