Buchla folding II
Buchla Folding 2 A wavefolder using modular arithmetic to reflect a signal at variable boundaries, producing infinite folding stages without discrete stage limits. Inputs
Input (audio): Signal to fold. Drive (1–32): Multiplies the input amplitude before folding. Higher values = more folds. Threshold (0–2): Sets the reflection boundaries at ±T/2. Lower values fold more aggressively at the same drive level and reduce the output amplitude range.
Output
Folded audio signal, bounded to ±Threshold/2.
Usage Drive and Threshold both increase fold density but interact differently. Drive pushes the signal harder into the folding boundaries. Threshold moves the boundaries closer to zero, which also increases fold count but simultaneously compresses the output range. For classic Buchla-style folding, set Threshold to 2 (boundaries at ±1) and sweep Drive. For more extreme timbres, lower Threshold while keeping Drive moderate.
