clocked-looping demo for norns

clockcut

simple demonstration of clocked looping / delay with softcut on norns

usage

at present, the demo has no interactive UI. it exposes parameters which are designed for MIDI mapping.

parameters

• clock_mul: multiplied by the clock beat duration to yield loop duration

• speed_ratio: speed of the virtual tape, as a ratio

• speed_tune: speed tuning offset, in cents

• rec_level: level at which input is written to the buffer

• pre_level: level at which existing buffer contents are preserved

• fade_ms: crossfade duration in milliseconds

EQ parameters

this script includes an EQ class which attempts to provide more usable controls for softcut's state variable filter.

• eq_mix: wet/dry mix

• eq_tilt: -1 = lowpass, +1 = highpass

• eq_select: mix in bandpass/bandreject. for positive values, this acts as gain around FC; for negative values it doens't (yet) act as a parametric cut; rather it brings in frequencies outside of the tilt control in addition to supressing around FC.

• eq_rez: resonance control. also could use some scaling work

TODO:

• raw midi clock mode (handle PPQ ticks directly)

• internal looping mode (ignore clock and division sequence)

• tweak EQ parameters

• trigger params to reset, clear, etc

• more voices (somehow)

• feedback routing (somehow)

• duration sequences

• position sequences?

• more UI:

  • display: show phase, etc
  • input: control parameters directly (assignable/meta?)
