Vibrato is a technique employed by singers and many instrumentalists (including guitarists, violinists, trumpet players etc) that slowly fluctuates the pitch of a resting note. These make them useful for changing other parameters such as filter cutoff or amplitude, or in the case of vibrato: pitch. So LFOs are below the human hearing range – if we plugged one into a speaker you might feel some change in air pressure or hear a click, but as an oscillator it’s inaudible. This range is sub-sonic, sub meaning below and sonic meaning audible. LFO stands for Low Frequency Oscillator, and would ordinarily function between about 0.01 Hz and 20 Hz. It’s been around for years to transmit radio signals. As a concept, I struggled with it for years until I had a eureka moment – I was unsure how it different from standard pitch modulation.
The term FM is probably (or at least until not that long ago) a household term which you would have come across through radio (see also AM, or Amplitude Modulation). So without further ado, let’s start with some background… Frequency Modulation Yes, it’s not a walk in the park to program compared to standard subtractive synthesisers, but it’s capable of producing the same detailed timbre sounds as its forefathers, and going further in the process. Ulrich owns one of the few external DX7 programmers, giving a slightly more sympathetic view to the complex matrix and cross modulation capabilities of the beast. Here’s an extract from a 1987 issue of Keyboard Magazine where Eno himself details four of his DX7 patches:
Here’s what the FM8 manual has to say about the DX7:īoasting aftertouch, velocity sensitivity, a new type of synthesis that was very different from analogue subtractive synthesizers, a new protocol called “MIDI,” and a shockingly low list price, the DX7 was an instant hit and went on to become the best-selling synthesizer of its time.Īmbient overlords Brian Eno and Ulrich Schnuass famously used the DX7 as workhorses in their music, the former on many of his eighties albums. One thing I think it really excels at too, is expressive ambient pads, and that’s what we’re going to have a look at today.įM8 is based on Yamaha’s DX7, which was released in 1983. Polarising the music production market and arguably changing synthesisers forever, the DX7’s architectures was based on frequency modulation (more on this later) and could create incredibly complex sounds with ease. Renowned as being a sod to program though, many users were confined to its trite classic sounding presets. Native Instruments’ FM8 is monster of a synthesiser capable of a vastly broad palette of sounds ranging from brutal Skrillex transformer-type bass to searing pads and leads to late 80s/early 90s rave sounds and beyond.
