Description
Unlock the full potential of your modular synthesizer setup with the Buchla 257e Control Voltage Processor. This versatile module is designed to expand the creative possibilities of your rig by offering both linear transformation and advanced slew processing. Featuring dual independent voltage processors, the 257e allows you to manipulate control voltage inputs with precision, enabling the creation of complex, non-linear functions. The top section mirrors the functionality of the 256e, with the addition of user-defined breakpoints for even greater control over your sound.
What sets the 257e apart is its bottom section, which includes three independent, dual-input slew processors. These are voltage controllable, allowing you to fine-tune slew rates between 0.1 and 10 seconds, and switch between rate and time modes for each channel. Whether you're crafting waveforms or integrating pulse-based functions into your sequencer, this module offers a wealth of options for sound shaping. The intuitive LED display provides real-time visual feedback, making it easier to navigate complex signal paths and adjust parameters on the fly.
