Building a Waveform Generator When starting out in the DIY synth space, one of the first projects people typically tackle after creating their first oscillator is an analog sequencer—like the “baby-8.” It’s a simple circuit that steps through a sequence of adjustable voltages. And if you use those voltages to control an oscillator you’ll get… Read more: Waveform Generator

An Experiment in Tone One day I was flipping through random electronics parts on AliExpress and came across a chip I hadn’t seen before—the TDA1524. After popping open the datasheet, it appeared to be a tone control chip with voltage-controlled inputs for Bass, Treble, Volume, and Balance. Apparently they use this chip in car stereos,… Read more: TDA1524 VC Tone Filter
