PROS
- • Remarkable flexibility for complex modulation routing and shaping.
- • The characteristic curve adjustment adds nuanced envelope possibilities.
- • Solid build quality; feels robust despite the compact 16HP footprint.
- • Three channels offer a surprising amount of functionality in a small space.
CONS
- • The learning curve is steep for those unfamiliar with function generators.
- • Power draw is a bit higher than average, impacting PSU capacity.
- • Bound input functionality could be more clearly explained in the manual.

Frequently Asked Questions
The 'Bound' input acts as a threshold, limiting the envelope's output range; it's useful for preventing runaway modulation or creating softer, more controlled responses.
While both offer multi-channel function generation, the Boundary Layer emphasizes envelope shaping and modulation routing with its unique characteristic curves and bound input, providing a different workflow.
Absolutely! While it's capable of complex routing, you can easily configure each channel as a straightforward AD envelope, offering a wider range of possibilities than a standard envelope module.
