Provides a comprehensive and improved Daisy Host API, a better clock detector, and support for delay-based effects. #68

colinbdclark · 2024-07-10T02:19:34Z

This "vaio-under-the-stairs" PR resolves gh-22, gh-66, and gh-67, and introduces an initial prototype for gh-65.

Highlights include:

A significantly refactored Host API and support for all the Daisy devices I own or have designed myself (which will need another round of refactoring to reduce duplication among Device implementations)
Improvements to the ClockDetector signal so that it is more accurate
Initial support for multi-segment fit calibration of CV inputs
Implementation of low-level delay lines, circular buffers, and higher level signals that provide support for multi-tap delays, delay modulation, comb filters, allpass filters, and reverbs
A series of examples illustrating pre-80s reverb algorithms and 80s-era chorus effects
