Noise Toaster Lo-Fi Synth Build and Analysis: Part 5 – Attack Release Envelope Generator
Adding an LFO to modulate our VCO‘s frequency has already made our synth much more interesting. Let’s step things up a notch by adding another CV source – an AREG or Attack Release Envelope Generator. This is part 5 of a multi-part series about the MFOS Noise Toaster Lo-Fi Analog Synthesizer. Make sure to check…

Noise Toaster Lo-Fi Synth Build and Analysis: Part 4 – Low Frequency Oscillator (LFO) Circuit Analysis
Previously in this multi-part series on the Music from Outer Space Noise Toaster Lo-Fi Analog Synthesizer, we built and analyzed the main Voltage Controlled Oscillator (VCO) circuit. The VCO can be modulated by the Attack Release Envelope Generator (AREG) and the Low Frequency Oscillator (LFO). In this blog post we will build and analyze the…

Noise Toaster Lo-Fi Synth Build and Analysis: Part 3 – CV Mixer, Expo. Converter, and VCO
The Noise Toaster is built around a ramp core analog oscillator which acts as the synth’s main signal source. The frequency can be modulated by control voltages from various sources – this makes it a Voltage Controlled Oscillator (VCO). In this article, we take an in-depth look at how the Noise Toaster’s VCO circuit functions.…
