I picked up a Sequential (DSI) Prophet Rev 2 polyphonic analog synthesizer a couple of weeks ago. After two weeks of playing, I decided to make a recording and talk about it.
First a few terms. “Analog” means that the sound is created by electronics as a continuous electrical signal which is then manipulated by other electronics. I know,obtuse, but that definition is a contrast with “digital”, which means the sound is created and manipulated by a computer. Most of the first commercial synthesizers were analog.
I said it was a polyphonic synthesizer (poly-synth). In this case “polyphonic” means more than one note can be played at once, sort of like a piano, with each note being distinct. The distinct note is called a “voice” – my Prophet Rev 2 is an 8 voice synthesizer (16 voice Rev 2s exist – more about this later). The way this works is that each voice is played by a completely different synthesizer! In the late 1970s, Dave Smith perfected a way for a computer to store values for a synthesizer so that all of the different voices (synthesizers) could have the same sound though the user only has to set up the sound once (one set of controls). It also let the user save sounds. This instrument was the Sequential Circuits Prophet 5. It helped to revolutionist the music industry and, actually, music itself.Continue reading
