Voltage Controlled Slope
Hello! You seem to have gotten a M4TM VCSlope module to build! Nicely done, let's get started.
First, what is this module? It's a tweaked version of a universal slope generator, explored fully by synthesizer design genius Serge Tcherepnin (he's still around -- we're Facebook friends, basically bffs). It's an incredibly versatile circuit that's the backbone of famous, popular Eurorack modules like Maths (and clones) and various other DUSG modules you'll see everywhere.
Second, what is this module? Yup, get it, I designed the prototype versions of this module as a way to understand the hype. A slope generator creates a voltage that slopes up, then down. It can retrigger itself, so it can be a LFO or a VCO. The rise and fall shapes are adjustable from exponential to logarithmic. In this version of the circuit, you've got voltage control over these slope shapes. An audio signal can be processed with the core of this circuit, which will limit how fast (and what shape) the signal is allowed to rise and fall by, which behaves like a simple low-pass filter. There's outputs for the retrigger signal, the "slope-is-falling" signal, a DC-decoupled signal, and the output signal. There's an attenuverter available, making voltage tweaks possible.
This circuit can be:
A VCO
An LFO
A simple envelope generator
An envelope follower
A transient detector / trigger generator
A VCF
other stuff I can't even think of right now
This circuit really shines when paired with a second one or more than just two. Crosspatching a bank of these modules together can yield surprising, complex, non-repeating generative soundscapes.
