Demonstration of the new allpass and comb filter modes of Bionic Lester. The patch is simple. One Hertz Donut 3 is patched into both inputs of Lester(routed in parallel) and its fold/mod controls are sometimes turned. The Lester outputs are panned hard left and right. First, allpass phasing with added dry signal is demonstrated.  Then, positive comb feedback with varying delay line lengths, resting frequently to let the feedback develop. Last, negative comb feedback and more tweaking. No other effects (or Lester overdrive)were used. There is occasional LFO modulation of delay line length.
