use new table-based dspkit classes for performant envelopes with variable
audio-taper curves are applied for levels (including record / erase.)
arbitrary curves are allowed for filter parameters and phasor rate.
breaking change:
filters use pre-computed coefficient tables and linear pitch inputs. for SVF cutoff, the pitch scale accepts MIDI note numbers. for the pre-record lowpass, an arbitrary unit range is used (but this should probably be changed for consistency.)
