Critic Reviews

Buchla 200e: Part 2

soundonsound.com

The Buchla 291e Triple Morphing Filter is lauded for its innovative, digitally controlled analogue band-pass filters that can create dynamic soundscapes. It shines in its ability to morph between filter snapshots, offering a unique sonic palette. However, the filter's maximum frequency cap at just over 4kHz might limit some users, and the manual isn't very user-friendly, which can be frustrating for newcomers. Overall, the 291e is a powerful addition for those looking to explore complex filtering in modular synthesis, though it might not be for everyone.
