Frequently Asked Questions
The Aloysius's logarithmic, exponential, and linear curve options are more granular than many basic envelopes, allowing for smoother, more organic transitions.
It’s generally sufficient for most VCFs, but very sensitive or low-input VCFs might require attenuation or a buffer.
While it lacks the extensive features of high-end modules, it excels at its core function, offering a surprising amount of control within its compact footprint.
