Raph Levien	e3b5ceebfc	Implement overdrive in resonant filter This patch implements nonlinear distortion in the resonant ladder filter. It's based on the differential equations in the Huovilainen '04 DAFx paper, but using matrix exponential to compute the evolution of the state variables. The implementation is scalar (and calls into sqrtf), but designed to be implemented in very efficient SIMD.	12 years ago
Raph Levien	68b44a4a89	Gather more stats Add a button to capture raw start and end callback time (just putting it in a text buffer so it can be copied), which is useful for making plots. Also a bunch of commented out code to provoke priority inversion or sudden increases in load (which exercises the governor), again for the purpose of probing performance and making plots.	12 years ago
Raph Levien	ee72c697c1	Add resonant filter to C++ synth This change adds a (single) resonant filter to the C++ synth unit, and wires up both USB MIDI and on-screen controls for cutoff and resonance. Also fixes a bug in KnobView which caused the knob value to jump around.	13 years ago
