Making a simple FM synth, part 3: Playing with frequencies
Watch the video
- (2:30) MINUS frequencies??? This makes sense... at NAMM this year, the Technicians of the Museum of Techno spoke to Cynthia Webster of Cyndustries.com, who makes an analog FM oscillator called the Zeroscillator. She's very proud that the oscillator is "through-zero", so if you tell it to play a negative frequency, it'll cycle through its waveform in reverse direction. I'm going to get a Reaktor oscilloscope going, I think, to investigate this... I'd like to see what it looks like.
- Watch the modulator's A input value going up and down... it feels like larger values, more frequency modulation, make for brighter sounds.
